Dental Prosthetic Options

Dental Prosthetic Options S.N.: Introduction: Prosthetic options to replace a missing tooth fall into two main categories: Fixed prostheses and removable prostheses. When choosing the suitable treatment option to replace a missing upper incisor, multiple variables involving the patient wishes, expectations, dentist skills and training, cost of treatment, and clinical findings should be taken into consideration (Al-Quran et al., 2011). These factors will have a strong influence on the short and long terms success of the treatment selected. Based on the conservation of neighbouring teeth and annual failure rates, dental implants are the treatment of choice to replace a missing central maxillary incisor, followed by conventional bridges, and removal partial dentures (Pjetursson Lang, 2008). Facial growth in relation to age: Craniofacial development is a continuous process that starts intra-uterine and has shown different rates between males and females (Brahim, 2005) . Skeletal maturation in males is reported to be reached at the age of 20, while females reach the maturation phase earlier, at the age of 17-18 years (Heij et al., 2006). Therefore, it has been recommended, when selecting the prosthetic option to replace a missing tooth, to take the patient’s age into consideration. Dental Implants should be avoided until the cessation of jaw development mentioned earlier (Daftary et al., 2013) or after the end of the growth spurt (Heij et al., 2006). If dental implants are used before the vertical maturation is reached, it will not grow vertically with the alveolar bone and will be submerged at different levels depending at the patient’s age when the implants were inserted (Brahim, 2005). Dental trauma and the surrounding tissues: In most scenarios, it is rare that a single incisor will be traumatized with no damage on adjacent incisors, surrounding bone, or soft tissues. If any damage sustained to neighbouring teeth, the status and prognosis of these teeth should be assessed, as it will have a strong impact on the selection of the definitive treatment option. Traumatic avulsion of teeth, account for 0.5% 3% of all dentoalveolar trauma, and it is associated with damage to the alveolar bone, specially the buccal plate (Andreasen, 1970). After tooth extraction, reduction of the alveolar bone height and width can be as high as 50% in the first year (Schropp L, 2004) with the highest amount of bone loss within the first three months (Pietrokovski Massler, 1967). Bone loss is not even between the buccal and palatal bone plates, with more bone loss in the buccal plate (Pietrokovski Massler, 1967) and bone width than height (Van Der Weijden et al., 2009). There are several treatment options that could be used for replacing a lost maxillary central incisor: Removable Partial Denture (RPD): RPD have the advantages of minimal clinical skills required, minimal chair time, and preservation of neighbouring teeth. On the other hand, the patient satisfaction is low, with a sense of insecurity, high risk of accidental breakage, and loss. Still, RPD is the quickest, cheapest replacement option of a missing incisor, and usually used as a temporary treatment until healing is complete and bone remodelling is minimal. Resin Retained Fixed Bridges (RRB): Resin retained bridges share the advantage of removable dentures of having minimal effect on abutment teeth with no risk of pulpal injury and the reversible nature of the prostheses. It is also relatively of low cost and acceptable aesthetic result (metal frame could be masked by opaque cement on expense of translucency). The commonest failure associated with RRB is frequent debonding of 20% over 5 years (Pjetursson et al., 2008) which could cause social embarrassment to the patient. The patient could also be given an Essex Type retainer with a single tooth in the gap as an emergency prosthesis until recementation of the resin retained bridge is done. RRB could be used as a final prosthetic option but more often is used as an interim measure as it could be reversed at any time, with 87.7% 5 years prognosis (Pjetursson et al., 2008) If the prosthesis is planned to be a temporary option, Rochette type wings are made with holes to facilitate frequent removal. Conventional Bridge: This is an irreversible treatment, replacing the missing tooth with a 2 or 3 units’ conventional bridge. These offer superior retention and aesthetics over RRB by the mean of full coverage of the abutment teeth. The main drawback is the need to reduce the sound tooth structure of the abutments with 20% risk of nerve damage and higher caries risk. The reduction of tooth structure is more for porcelain fused to metal or full ceramic/Zirconia crowns than full crown which is a requirement in the anterior aesthetic zone. According to previous studies, â€Å"if the adjacent teeth are severed, or in need of being crowned, the conventional bridge is to be preferred (Annual failure rate: 1.14%)† (Pjetursson Lang, 2008). The success rate is reported to be 90 % for 10 years and 72% for 15 years (Pjetursson et al., 2008) and (Burke Lucarotti, 2012). Endosseous dental implants: When considering the success rate, dental implants are reported to have the highest documented survival rate of 94% for 5 years (Attard Zarb, 2003) and 89% over 15 years (Pjetursson et al., 2008). Dental Implants have numerous advantages over the previously mentioned treatment options. Comparing dental implants to other fixed treatment modalities, there is no danger of pulpable damage of adjacent teeth, as no abutment teeth preparation is involved. Implants also facilitate the patient’s daily oral hygiene routines around the prosthesis, since there are no connectors between the prostheses and abutment teeth, making flossing possible. Furthermore, the maintenance and regular follow ups by the dentist is easier for dental implants. Removing a conventional bridge is a challenging task compared to screw retained implant supported crowns which could be removed and re-inserted multiple times when required (not applicable to cemented crowns). For implant supported restorations in the anterior maxillary region, a detailed patient assessment, implant site assessment, and proper treatment planning is the key for a successful restoration. The planning should be derived from the restorative point of view not guided by the availability of bone. The following points should be carefully assessed: Lip position at rest and smile: The patient’s aesthetic expectations should be coupled with the upper lip position at rest and when smiling. In most cases, 2 mm of the incisal edge of the central incisors should show at rest, and it could be either 100% of all the incisors (high smile line), more than 75% visible (medium smile line), or (low smile line) showing less than 75% of the incisors. With low smile line lip position, the aesthetic challenges are lower, and the emphasis on soft tissue contouring and papilla regeneration is also lower (Tjan et al., 1984). If the patient’s expectations are high while having high smile line, patient education should take place prior to implant treatment as the implant treatment could be deemed a failure if did not meet the patient’s aesthetic requirements despite been successful in every other aspect. Attached gingiva and surrounding soft tissue: The attached gingiva could have thick, moderate, or thin architecture. Thick gingiva is more common than the thin biotype; it appears as a more stippled, flat fibrous band of attached mucosa, masking the underlying bony contours. It is associated with higher resistance to recession, better soft tissue contouring, and resistance to peri-implant disease. On the other hand, thin gingival biotypes are found in 15% of population (Tjan et al., 1984) and it is a thinner mucosal layer with the bony scalloping showing through it. This type is more prone to exposure of the implant and compromising the aesthetic result (Tjan et al., 1984). The thin biotype has been associated with long triangular teeth and more incisally positioned contact points, while the thick biotype is associated with shorter, square crowns with more apically positioned contact points (hence, more papillary regeneration). Implant size used: Implant size has a direct effect on the emergence profile of the coronal restoration and aesthetics. Natural existing teeth and available bone are helping factors when selecting the right implant diameter, while implant length should provide a safety distance to the surrounding anatomical structures. The implant diameter should allow 1.5 mm between implant and neighbouring teeth (and 3mm between adjacent implant fixtures) (Jivraj Chee, 2006). The gingival biotype also should not be overlooked when selecting the fixture diameter, for example; if wider implants are used with thin gingival biotype, the risk of recession is higher (Rodriguez Rosenstiel, 2012). Implant position: For the most aesthetic emergence profile, implants should be placed 1.5 mm – 2 mm from the adjacent tooth, 3mm – 4mm apical to CEJ (Jivraj Chee, 2006), and ideally should be placed under the proposed cingulum of the coronal restoration. A diagnostic wax up and a prefabricated surgical stent are of very important in deciding the crown and implant positions, and evaluating the amount of bony defect and the need for bone graft. Transfaring the surgical stent into the patient’s mouth will allow the visualization of the amount of incisor show and smile lines. The implant position and angulation will dictate the abutment type and the retention method used for the restoration (screw or cement retained). Available bone quality and quantity: Bone density has been classified by Lekholm and Zarb (1985) into 4 categories: Homogenous compact bone, Thick cortical bone around dense trabecular bone, Dense trabecular bone covered by thin cortical bone, Very thin cortex enclosing minimal density trabeculae. Types 3 and 4 are associated with more failure rates, and are more found in the maxilla. Therefore, under -preparation of the osteotomy site could be done to gain higher initial stability. Branemark et al 1977 defined ossteointegeration as â€Å"direct structural and functional connection between living bone and load carrying implant†. Implant fixture should be in direct contact with healthy bone in three dimensions. Therefore, the amount of available bone required around any dental implant is 1.5 mm buccally and palatally, 3 mm between adjacent implants and at least 1.5mm -2mm between implants and adjacent teeth (Misch, 2008) and (Rodriguez Rosenstiel, 2012). If buccal bone width is not sufficient, a smaller diameter implant that will be functionally and aesthetically sound could be selected. It will also allow slight palatal positioning (Rodriguez Rosenstiel, 2012). Bone grafting/augmentation procedure could be done to add the bone thickness (Esposito et al., 2009) and bone could be sourced from: Patient’s own bone (Autogenous graft): commonly could be harvested from calvarian bone, iliac crest, mandibular ramus or chin. This provides highest reported success rates (Esposito et al., 2009). Different human bone (Allograft): usually from cadaveric bone. Bone undergoes special treatment to be deproteinized and freezed (Esposito et al., 2009). Animal sources (Xenograft) usually cows or pigs. Synthetic materials (Alloplast): artificial graft material which could be used solely or in conjunction with autogenous grafts (Esposito et al., 2009). Bone regeneration membranes: these are used to act as a barrier between the superficial soft tissue and the grafted bone or material to prevent ingrowth of the fibrous tissue and allow pure bone development. These membranes could be either natural or synthetic, resorbable or non- resporbable. If block bone graft is used, it should be allowed to heal for minimum 3 months before implant placement, while bone augmentation with alloplastic materials and membranes could be done simultaneously (Esposito et al., 2009). It is worth mentioning that porcine- derived bone and membranes may not be acceptable by some patients based on their religious beliefs and a specific consent should be obtained. The bone height will also impact the papilla formation, together with the crown shape and level of contact points; the papilla regeneration is favourable is square crown, broad apical contact points, and when the distance is around 4-5 mm between bone crest and contact points (Rodriguez Rosenstiel, 2012) and (Tarnow et al., 2003). Vertical bone augmentation has been shown to be unpredictable (Esposito et al., 2009) and the patient should be aware of the black triangles (lack of papilla) if vertical bone is deficient (Tarnow et al., 2003). Conclusion: Based on the previously discussed factors and the evidence available, dental implant would be the treatment of choice if the neighbouring teeth are of good prognosis and the aesthetic results are realistic. It is safe to place an implant in 20 years old male, as the growth of the jaws is complete. A diagnostic wax up and stent could be made to evaluate the aesthetics, and available bone. A 4.5 mm buccal width is not enough to place a suitable size implant in a suitable bony envelope, so a block done graft for will be needed before the implant placement. If the source of the trauma was sports related and likely to occur again, a mouth guard should be worn to protect the implant and teeth during activity. Bibliography Abt, E.C.A.B.W.H.V., 2012.

Bankruptcy Essay -- essays research papers

Bankruptcy, today, is a very common thing among companies and individuals alike. Sadly enough there were as many bankruptcy cases filed in federal courts, as there were all other cases. The American bankruptcy law allows people to avoid paying their debts, by offering the debtors a discharge, which eliminates all their legal responsibilities. However, bankruptcy is a controversial issue amongst religious members of the Jewish population, for one must question whether it is morally correct to avoid paying a dept by filing for bankruptcy. According to the torah, a debt is an obligation that must be fulfilled. Consequently, if a bankruptcy discharge is invoked, under the strictness of Jewish law, one is still required to pay back the money no matter how long it may take him. According to Bais Din the debtor must hand over his property, with a few exclusions, to the creditor, and if this does not cover what he owes the creditor, then every time the debtor acquires new assets, he pays the creditor until he no longer owes him anything.   Ã‚  Ã‚  Ã‚  Ã‚  According to Halacha there is a way for the debtor to be discharged. This is through â€Å"Yeush†. This term denotes that this is the point where a person no longer believes he will recover the object he has lost. In this case, the creditor loses hope of being paid back the money the debtor owes him. Therefore the debtor is free from his obligation to pay the creditor. According to some poskim, yeush does not discharge the debtor, unless the circumstances, such as where the debtors fields are ruined by a flood, the debtor is in, makes the creditor lose hope of ever being paid back According to others, yeush can discharge the debt if the debtor becomes impoverished only and not because he didn’t want to pay back his debt.   Ã‚  Ã‚  Ã‚  Ã‚  If the debtor does not become discharged through the creditors yeush, there is one of two ways to obtain a bankruptcy discharge through halacha. The first way is through liquidation. This is where the debtor hands over all his property, with keeping some exempt property, and this covers his debt to the creditors and he is now free of his obligation to pay them. The second way is through reorganization. The debtor makes a plan to repay his creditors over a number of years, with a minimum payment required for each year. When he has finished with these payments,... ...t that the halacha is in accordance with one aspect of the debate, this being called â€Å"kim li†. Now the plaintiff, the creditor, can only win if he proves his case according to the view chosen by the defendant. In this case of a â€Å"kim li†, bais din has to determine whether dina d’malchusa dina applies to a bankruptcy discharge. As mentioned above, the Rema states that it does, and therefore the defendant may win this case and be free of debt. However, there is a question now as to whether the defendant should pay the creditor because of religious obligation. In a regular bankruptcy discharge, the debtor is free of all his debt and thus it may assumed in this case that the defendant is free from debt because of the use of â€Å"kim li†.   Ã‚  Ã‚  Ã‚  Ã‚  Working through secular law, unfortunately, may be the only way to clear debts owed between many. Although it is not the preferred way to do business, especially between religious Jews, it is the way the world works and it makes it easier to get rid of the debt between Jews and non-Jews. This paper is a very revised version of bankruptcy and the Halacha perspective, but I hope it provides all the information that is necessary.

Billie Holiday (Lady Day) essays

Billie Holiday (Lady Day) essays Billie Holiday,also known as Lady Day was born in Baltimore in 1915. She spent hard time in her childhood. Billie Holiday's grandfather was one of 17 children of a black Virginia slave and a white Irish plantation owner. She was born from 15 year-old father and 13 year-old mother. It is shown in the first line of her famous autobiography Lady Sings the Blues, "Mom and Pop were just a couple of kids when they got married. He was eighteen, she was sixteen, and I was three." Her musician father left the family early, and her mother wasn't able to keep her consistently which resulted in Billie often being put in care or relatives who abused her. She was raped at age of 11, became a prostitute when she was 14, and was arrested for prostitution year after. She moved to New York in 1929 and started working as a maid and a prostitute, and made her singing debut in bars and restaurants. In 1935, she recorded for sides that contains What a Little Moonlight Can Do, and Miss Brown to You, and acquired her recording contract. Lady Day was with Count Basies Orchestra in 1937. However, only three songs from radio broadcast are the all exist works because they were signed to different labels. She also worked with Artie Shaws Orchestra for a while next year, but the same kind of problem happened and only one song was recorded. She had her voice at its strongest during the period with Decca between 1944-1949, and she made her biggest hit with Love Man. Unfortunately, she became addicted to heroin and put in jail just after this period. She became famous, and Lady Day got a chance to make one Hollywood movie in 1964. She was not really pleased by playing maid, she came to perform with Louis Armstrong who is her early idol. After 1950, her story slowly starts declining. Due to the heroin abuse and excessive drinking continued, her voice was deteriorating fast, and by 1956 she was completely past her prime. Her final accomplishm...

Beowulf vs Ulysses Essays

Beowulf vs Ulysses Essays Beowulf vs Ulysses Essay Beowulf vs Ulysses Essay Contrast: Ulysses and Beowulf When an individual envisions epic poetry, you cant help but think of dragons, heroes and huge battles. In the two epic poems Ulysses by Lord Tennyson and Beowulf translated by Burton Raffle, you find the two major heroes who are very intelligent above all other heroic attributes. Throughout each epic, you find the hero using the combination of strength, intelligence and unbreakable courage. The heroes are natural born leaders, that others around them cannot help but be mesmerisms by. A major connected between the two epics was the definition of dervish is evident. Through the Journeys of the main characters, Beowulf and Ulysses are each portrayed as heroes in the poems as they lead their men on great adventures. While both display many characteristics of heroes and leaders, Beowulf first act of leadership in the poem is when he offers to fight Greened unarmed. This is an example of leadership because he is standing up above everyone else, when all the other men are scared to. While all the other men are fearful and worried about Greened attacking, Beowulf is able to stay fearlessly as he awaited the arrival of Greened. From Ulysses poem it is evident he was a true leader, captaining ships and winning many battles in the Trojan War. Beowulf was also a very prideful individual, for example in his fight against Grenade. He was trying to seem heroic fighting without a weapon. You can also see this as an example of Beowulf enormous about of pride; he wants the glory from killing Grenade and that glory would be given if he killed him without a weapon. But Beowulf only longed for fame leaped back Lento battle. He tossed his sword aside, Angry; the steel-edged blade lay where Theyd dropped it. If weapons were useless hed use Shes hands, the strength in is fingers. So fame comes to the men who mean to win it and care about nothing else! (Line 605-608) In the quote it is so present that Beowulf only seeks fame, and glory of defeating Greened.

Bodily Effects of Hazardous Materials Research Paper

Bodily Effects of Hazardous Materials - Research Paper Example Some technologically advanced landfills also leak from time to time. The tanks used to store petroleum or chemicals can easily leak and catch fire. Tanks in the underground can weaken and leak their hazardous materials. There are many risks when transporting hazardous materials, for example, when trucks overturn or train crash. People can also dump hazardous materials in sewer systems, warehouses that are abandoned or remote areas, ditches to escape the costs of safe dumping. There are three routes of entry that hazardous materials enter into the body: ingestion, absorption, and inhalation (SYKLI, 2012). Health risks commonly linked with hazardous materials are grouped as acute and chronic. It is a must for one to get medical attention when one is exposed to harmful materials. Most of these exposures have treatment if one takes immediate action. Acute/ immediate effects result from a short-time exposure to hazardous substances. Some of the immediate warning signs include headaches, nausea, dizziness, skin, eye or respiratory damage or irritation, unconsciousness and even death. The most noticeable and common warning signs are skin, eye, and respiratory irritation. Occurrences of deaths are very rare, and the majority of these exposures can be treated if immediate attention is taken. Chronic/delayed effects occur after a long time exposure to hazardous materials. The exposure can also be very small over a lengthened period. The effects mainly target the liver and kidneys as all chemicals that get into the body pass through these organs. A perfect example of an unending health effect is called lung cancer from radon inhalation or cigarette smoke. There are some products that can cause large health risks, though used as directed. For instance, there are products taken off the market or banned due to their health or environmental risks, for example, those containing PCTs, PCBs, asbestos fibers, mercury, lead and arsenic

Corporate governenance Essay Example | Topics and Well Written Essays - 1500 words

Corporate governenance - Essay Example lowed by series of consequences in the capital markets including managerial, and accounting corruption or weakness of the internal control systems panel on activities of the financial institutions. Based on the above the global economy has witnessed the introduction of new terminology namely Corporate Governance to detect the weakness in the companies’ control. The concept of the Corporate Governance has been developed to direct the management and business inside and outside the company.
