Study of Speech Clarity and Acoustic Effects of Titanium Partial Dentures Made by CADCAM Technology

What this Trial Is About

Researchers are evaluating the speech performance of partial dentures made from CADCAM milled titanium compared to traditional cobalt-chromium frameworks. Partial dentures help restore oral function and appearance for people missing some teeth. While titanium offers benefits like being lightweight, biocompatible, and corrosion-resistant, its effect on speech clarity and sound production has not been well studied. The study compares two ways of making partial dentures the conventional method using cobalt-chromium metal frameworks made through manual impression processes, and a modern digital approach using computer-aided design and manufacturing to create titanium frameworks. The titanium dentures are expected to be thinner and fit more precisely, potentially allowing more natural tongue and lip movements. Participants will receive either the cobalt-chromium or the titanium dentures fabricated by these methods. Participants will be evaluated through speech analysis and intelligibility tests at one and three months after receiving their dentures. The study includes assessments of speech sounds, focusing on clarity and pronunciation. Researchers will monitor how the dentures affect speech performance over time to better understand if titanium dentures provide improvements. The total study duration for each participant includes these follow-up evaluations.
