REPLACEPatient Perception and Oral Function of Implant-supported Restorations for Posterior Teeth

This clinical trial investigates how different dental treatments affect chewing ability and overall oral health quality of life for people missing back teeth. The study aims to determine whether implant-supported crowns, removable dental prostheses, or no treatment affect patients' perceptions of their chewing function and oral health differently. It also compares two digital methods for assessing how teeth come together and whether crowns that are joined together (splinted) or used individually (non-splinted) lead to different biological and technical outcomes. The study targets adults who are in good health, have missing back teeth, and are considering implant-supported crowns to replace these teeth. This research is significant as it may help improve dental care by identifying the most effective and patient-friendly treatment options for those with missing teeth. Participants will undergo various tests and procedures during the study. Initially, they will be screened with X-rays and other assessments to ensure they meet the study criteria and do not have conditions that could interfere with treatment. Participants will receive implant-supported crowns and undergo tests to measure their bite force, chewing time, and muscle activity during chewing. They will also complete questionnaires about their oral health and ability to chew different foods. Some participants will have their crowns joined together, while others will have them as individual units to assess the differences. Digital scans and traditional methods will be used to record how teeth meet during biting. The study will follow participants over time to assess outcomes like changes in bone levels around the implants and any complications with the crowns. This will help determine the most effective treatment approach for improving oral function and quality of life.
