Artificial intelligence applications in smile design dentistry: A scoping review.

Purpose: Artificial intelligence (AI) applications are growing in smile design and aesthetic procedures. The current expansion and performance of AI models in digital smile design applications have not yet been systematically documented and analyzed. The purpose of this review was to assess the performance of AI models in smile design, assess the criteria of points of reference using AI analysis, and assess different AI software performance.

Strains in the implant collars supporting a cantilevered cross-arch bar prosthesis. An in vitro study.

Purpose: To examine the strains in the collar area of implants supporting a cantilevered cross-arch bar prosthesis during vertical load application.

Materials And Methods: A milled cross-arch metal framework supported by four implants in a trapezoidal design was supported in polymethylmethacrylate. T-strain gage rosettes were attached to the crestal areas of the implants with two grids, one recording circumference strain of the crestal area of the implant and the second recording vertical strain, torquing strains of the implant.
