THE EFFECTS OF DIFFERENT ATTACHMENT SYSTEMS ON STRESS IN 2-IMPLANTRETAINED OVERDENTURES

Year 2014, Volume: 2 Issue: 3, 267 - 271, 30.12.2014

Abstract

Osseointegrated implants have been used to improve denture support, stability and retention. Currently, the placement of 2 implants and the fabrication of an implantretained overdenture is considered by some to be the standard of care. The influence of various types of attachments on stress distribution of 2-implant-retained mandibular overdenture designs has not been sufficiently assessed. The purpose of this study was to compare the load transfer characteristics of 5 attachment systems for 2-implant-retained mandibular overdenture designs. One photoelastic model was fabricated having 2 screw-type implants (3.75 X 13 mm) embedded in the interforaminal region and implants were parallel to each other and vertically oriented. Five retention mechanisms were studied on model; a bar with yellowcolored clips, a milled galvanoformed bar, a bar with two clear distal locator attachments, a bar with two distal ceka attachments, clear locator attachments. For measurements of stress a vertical load 135 N was applied unilaterally to the central fossa of the right first molar. The resultant stresses that developed in the supporting structure were monitored photoelastically and recorded photographically. A bar with two clear distal locator attachments and,clear locator attachments showed higher stress than other attachments

FARKLI TUTUCU SİSTEMLERİN 2-IMPLANT TUTUCULU OVERDENTURE UYGULAMALARINDA STRESLER ÜZERİNE ETKİSİ

Year 2014, Volume: 2 Issue: 3, 267 - 271, 30.12.2014

Abstract

Osseointegre implantlar protezin destek, stabilite ve tutuculuğunu geliştirmek için kullanılmışlardır. Günümüzde 2 implant ve üzerine yapılan implant tutuculu overdenture uygulamaları standart tedavi olarak kabul edilir. Farklı tip tutucuların, 2-implant tutuculu mandibular overdenture tasarımları üzerindeki stres dağılımına etkisi yeterince değerlendirilmemiştir. Bu çalışmanın amacı; 5 tutucu sistemin, 2 implant tutuculu mandibular overdenture tasarımlarında yük transferini kıyaslamaktır. 2 adet vida tipi implantın (3.75 X 13 mm) interforaminal bölgeye, vertikal düzleme ve birbirine paralel olarak yerleştirildiği 1 fotoelastik model üretilmiştir. Modelde 5 tutucu mekanizma değerlendirilmiştir; Bar-sarı klips, bargalvano, bar-distal locator (şeffaf), bar-distal ceka, locator (şeffaf). Stres ölçümü için, tek teraflı olarak sağ birinci molar dişin santral fossasına 135 N vertikal yük uygulanmıştır. Destek yapıda gelişen stresler fotoelastik olarak izlenmiş ve fotoğraf olarak kaydedilmiştir. Bar-distal locator (şeffaf) ve locator (şeffaf) tutucu diğer tutuculardan daha yüksek stres göstermişlerdir.
