The Effect of Different Model Techniques on the Passivity of Fit of Implant supported Fixed Partial Denture.
ANDY KARAM NASSIF;
Abstract
This research was presented to evaluate the effect of different model techniques on the passivity of fit of implant-supported prosthesis.
A model simulating a clinical case was fabricated of epoxy resin with abutments of lower second premolar and lower second molar and a missing lower first molar.
Three models were fabricated, the first from 3D printed technology, and the second was a conventional cast and the third using milling technique.
The 3D printed and milled cast was fabricated using an optical virtual impression while the conventional stone cast was fabricated using a regular poly vinyl siloxane impression.
Five (three unit bridges) was fabricated on each group of cast to evaluate the passivity of fit on the master cast after attaching strain gauges on the mesial and dsital of each abutment. The measurement was done by measuring the strains transmitted to the model after seating the bridges and applying a 200N load.
The recorded measurements were statistically analyzed to compare between each channel in the three evaluated cast techniques.
