Background: The retention of cement-retained implant-supported restorations can be affected by surface treatments such as anodizing. This study aimed to assess the effect of the anodization of titanium abutments on their tensile bond strength to implant-supported lithium disilicate (LDS) all-ceramic crowns.
Materials And Methods: This , experimental study was conducted on 26 straight abutments in two groups of anodization and control.
Article Synopsis
- The study compares the accuracy and internal discrepancies of removable partial dentures (RPDs) made through different methods: conventional casting, CAD-CAM milling, and additive manufacturing.
- It reviews 25 research articles to gather data on the manufacturing precision of RPDs, revealing that CAD-CAM techniques generally display lower discrepancies but can still produce some outliers beyond acceptable clinical limits.
- While CAD-CAM methods offer benefits such as fewer appointments and quicker lab times, the study also highlights challenges like limited design programs for RPDs.
Statement Of Problem: The conventional method of fabricating removable partial denture (RPD) patterns is a time-consuming, expensive, and complex process, and the success of the treatment depends on the fit of the framework. Questions still remain as to whether the 3D-printing method is an acceptable procedure compared with the conventional method.
Purpose: The purpose of this in vitro study was to compare the fit of RPDs cast from 3D printed frameworks and conventionally fabricated RPDs according to the gaps between the framework and the reference model.
