This finding is in contrast with another study,22 which concluded that even after 1500 pulling cycles, there was no difference in the retentive properties of ERA attachments. After the first year, the marginal bone level, attachment level, and Periotest (Siemens AG, Bensheim, Germany) scores hardly changed. This stress increase is the reason that a concentrated arrangement of implants in the anterior area is not suggested. Magnetic retention in prosthetic dentistry. Effect of anchorage systems and extension base contact on load transfer with mandibular implant-retained overdentures. ****Profesor, Director de Prostodóntica Graduada y Postgraduada, Tufts University, Facultad de Medicina Odontológica, Boston, MA. 334 0 obj <> endobj It can probably be concluded that there is no difference between the bar and ball attachment methods.

Foi realizada uma revisão da literatura baseada numa busca em MEDLINE limitada a artigos em língua inglesa publicados de 1988 até o presente, e um grande número de attachments disponíveis no mercado dentário foi revisado com relação a vários fatores. Hemmings KW, Scmitt A, Zarb GA. The use of an alloy with a low modulus of elasticity precludes larger stresses at the bone-implant interface on the loading side than the use of a rigid alloy, for a superstructure of the same geometry. Attachment Systems for Implant Retained Overdentures: A Literature Review @article{Trakas2006AttachmentSF, title={Attachment Systems for Implant Retained Overdentures: A Literature Review}, author={Theodoros Trakas and K. Michalakis and Kiho Kang and H. Hirayama}, journal={Implant Dentistry}, year={2006}, volume={15}, pages={24-34} } The 5-year prospective randomized study by Gotfredsen and Holm6of over- dentures retained from 2 implants in the mandible showed a success rate of 100%, which was independent from the attachment system used (ball or bar). This result contrasts with those previously published from the same group, when in a group of 5 patients who were treated with maxillary overdentures retained by 2 stud attachments (either ball or magnetic), the absolute success rate was only 40% after a mean loading time of 6.4 years. It has been successfully used to retain overdentures as well as partial dentures. According to Payne et al,60 a treatment of implant overdenture, where marginal integrity and associated patrices/matrices are maintained regardless of modifications, as long as it continues as an implant overdenture, should be considered as a repair. A literature review based on a MEDLINE search limited to English-language articles published from 1988 to the present was performed, and a large number of attachments available in the dental market were reviewed with regard to several factors, including: (1) implant survival rate, (2) marginal bone loss, (3) soft tissue complications, (4) retention, (5) stress distri-bution, (6) space requirements, (7) maintenance complications, and (8) patient satisfaction. The purpose of this article is to discuss the potential effect of the different attachments used routinely in implant-retained overdentures on: (1) implant survival rate, (2) marginal bone loss, (3) soft tissue complications, (4) retention, (5) stress distribution, (6) space requirements, (7) maintenance complications, and (8) patient satisfaction. Several clinical measurements proved that 3-dimensional loads occur regularly during function. Freeman C, Brook I, Joshi R. Long-term follow-up of implant-stabilised overdentures. The way stress is applied to implants after osseointegration was one of the first factors considered and studied in implant dentistry. It appears that, according to the up-to-date published research, marginal bone loss cannot be related to the use of different attachment systems. 43. Engquist B, Bergendal T, Kallus T, et al. Menicucci G, Lorenzetti M, Pera P, et al. The McGill consensus statement on overdentures. Activation of the clips seems to be a frequent maintenance problem.53 Other complications are the fracture of the clips and relining of the prostheses. Prospective clinical evaluation of mandibular implant overdentures: Part II-patient satisfaction and preference. Sadowsky SJ, Caputo AA. Wolters Kluwer Health Complications encountered were associated with acrylic resin and denture teeth fractures, as well as some retentive component failures. Bidez MW, McLoughlin SW, Chen Y, et al. [email protected]. 15. Los nombres y fabricantes de los productos se mencionan solamente si se relacionan con los sistemas de retención como se citan en los artículos originales. Results of this study indicated that the increased function after the treatment seemed to cause a load-related bone formation, which minimized the physiologic age-related mandibular BMC. Selection criteria previously published in the literature are discussed as well. Further in vitro studies,30,31 finite element analyses,32–35 as well as in vivo studies,36,37 have confirmed that ball attachments probably provide higher stability with the load more evenly distributed onto the residual ridges on both sides of the dental arch. Meijer HJA, Starmans FJM, Steen WHA, et al. Clin Oral Implants Res 2000;11 Suppl 1:108-25. 1. Highlight selected keywords in the article text. In a critical literature review of all relevant articles from 1988 to 1999, Payne and Solomons59 concluded that there appears to be a need for a more uniform, consistent classification with solid criteria for determining prosthodontic success, in terms of maintenance and complications associated with mandibular overdentures. www.indiandentalacademy.com 17.

Other factors, such as bone quality and quantity, arch morphology and implant length, seem to play far more important roles in implant survival rates. Thus, the most important parameter for the rigidity of a superstructure becomes the material used. Most of the instances occurred during the first year of function. However, there is published evidence that shows a higher plaque index associated with magnet-type attachments. There are reports that favor ball attachments toward bars, in terms of maintenance requirements.61 However, maintenance of ball screws, and especially of magnetic keepers, is high. *Exresidente en Prostodóntica de Posgrado, Tufts University, Facultad de Medicina Odontológica, Boston, MA. Search for Similar Articles types of overdentures (e.g., partial). Federick DR, Caputo AA. Diese Faktoren werden für ein erfolgreiches Behandlungsergebnis sowie die langfristigen guten Erhaltungschancen einer Prothese als maβgeblich erachtet. Registered users can save articles, searches, and manage email alerts. The Influence of Attachment Systems on Implant-Retained Mandibular Overdentures. This fact does not seem to apply to other attaching mechanisms that have different mean retentive forces and standard deviation of retentive values. Nevertheless, it is noteworthy that Periotest values were significantly lower at year 5 compared to year 1 for all groups, a fact that probably indicates a higher rigidity at the bone-implant interface. Närhi TO, Hevinga M, Voorsmit RACA, et al. Of the patients, 6, including 2 from the ball group and 4 from the bar group, thought that the opposing denture was less retentive after implant therapy than before. 23. may email you for journal alerts and information, but is committed 1, 2 However, the efficacy of some endosseous implant systems now allows patients to be successfully treated with implant-retained overdentures. 0 Please try after some time. A comparison of three treatment strategies with ITI-dental implants. Therefore, the results of fatigue tests contradict clinical experience. I: A prospective study of the effectiveness of implant supported fixed prostheses. It is noteworthy that, although the patients who participated in this study were clearly advised to remove the dentures during nighttime, only half of them did. Overdentures (OVD) are removable dental prostheses that cover and rest on one or more remaining natural teeth, the roots of natural teeth and/or dental implants improving stability and reducing ridge resorption. §Professor, Director of Graduate and Postgraduate Prosthodontics, Tufts University, School of Dental Medicine, Boston, MA. Implant angulation: A measurement technique, implant overdenture maintenance, and the influence of surgical experience. The aim of this case report was to describe a prosthetic rehabilitation associated with an alternative model of polymer capsule for fixation system of implant-retained overdentures. Critérios de seleção previamente publicados na literatura também são discutidos. Attachment retained implant overdentures are functionally superior to conventional dentures and are effective and cost saving alternatives to fixed implant dental prostheses. The edentulous predicament. Spark erosion technique frameworks have also been examined72 in regard to patient satisfaction, and they proved to be a good alternative to the ball or bar/clip attachments. Retention of ERA direct overdenture attachments before and after fatigue loading. ; 3 Ship package containing your impression(s) AND completed RX form(s) to: Sterngold Digital Department; 4 Once your case is ready for processing, a Sterngold Sales Representative will contact you At the end, selection criteria previously published in the literature are briefly discussed. 10. 28. The applicable CDT codes pertaining to the prosthesis for 70. Karabuda C, Tosun T, Ermis E, et al. Allen EP, Bayne SC, Brodine AH, et al. It should be mentioned that the authors’ opinion is that the most favorable results in the most recent study were probably related to the number of implants that were rigidly splinted. Correct placement of the implants affects the maintenance of the attachment systems and, therefore, should be very carefully planned.
