AI prediction of post-denture facial esthetics in edentulous patients

Source article: The Role of Artificial Intelligence Models in Predicting Post-Prosthetic Facial Esthetics in Edentulous Patients: Clinical and Anthropometric Comparative Study

Abstract: Objectives Artificial intelligence (AI) is increasingly used in esthetic dentistry; however, its accuracy in predicting post-prosthetic facial outcomes in edentulous patients remains unclear. This study aimed to evaluate the ability of AI models to simulate post-denture facial esthetics compared with actual clinical outcomes. Materials and methods A prospective within-subject observational study was conducted on 14 completely edentulous patients receiving new complete dentures. Standardized facial photographs we…

The quick read

A prospective study of 14 edentulous patients compared actual post-denture facial photographs with AI-generated predictions from pretreatment images using Gemini and FaceApp, assessing patient preference, expert esthetic ratings, and quantitative anthropometric measurements.

Esthetic comparability suggests AI could help patients visualize outcomes and support communication, but the demonstrated lack of anthropometric accuracy means it cannot replace clinically driven prosthodontic assessment, and the very small sample leaves uncertainty about performance across diverse anatomies.

Main points
  • Prospective within-subject study of 14 completely edentulous patients receiving new complete dentures.
  • Standardized facial photos at T0 pretreatment and T1 posttreatment compared to AI images generated from T0 using Gemini and FaceApp.
  • Expert evaluation showed high inter-rater reliability with intraclass correlation coefficient >0.85 and no significant difference between real and AI images.
  • Anthropometric analysis found significant differences across most variables, indicating AI lacked quantitative accuracy despite visual similarity.
Gain

AI models Gemini and FaceApp generated post-denture facial images rated as esthetically comparable to actual clinical outcomes by patients and experts.

Problem

AI simulations failed to accurately reproduce quantitative facial anthropometric changes after denture placement despite visual similarity.

The rundown

Researchers enrolled 14 completely edentulous patients and took standardized facial photographs before and after new complete dentures, then generated predicted post-treatment images from pretreatment photos using Gemini and FaceApp.

Patient preference testing and expert esthetic scoring showed no significant differences between actual T1 photos and AI predictions, but paired anthropometric measurements compared with Wilcoxon and Friedman tests revealed significant quantitative discrepancies while symmetry was preserved.

What this doesn’t fix

Findings based on only 14 completely edentulous patients in a single within-subject observational design, limiting generalizability and statistical power.
