This trial tests whether a collagen matrix can match the standard tissue graft for improving gum shape around a single dental implant in the front upper jaw. Thirty adults with one missing tooth will receive an implant and then either a graft taken from their palate or a collagen…

This study is testing a new type of dental implant with a special surface (EK III NH) in 30 adults aged 20-80 who are missing teeth. Participants receive the implant and a temporary tooth replacement right away. Researchers will track how well the implant works over two years usi…

This study tests a collagen-based bone graft material (Bio-Oss Collagen) for sinus augmentation in people with bone loss and missing teeth. The goal is to see if it helps grow enough bone to support a dental implant. The study involves 36 adults who need a single implant in the u…

Researchers at Hanoi Medical University are studying whether small lingual appliances can correct an excessive Curve of Wilson at the lower second molars in people already wearing labial fixed braces. The trial uses a split-mouth design: one side of the mouth receives the auxilia…

Researchers compare two materials for the framework that supports a full set of replacement teeth on four dental implants in the lower jaw. Ten completely edentulous patients receive either a titanium or a nano-carbon fiber-reinforced CAD/CAM framework. The study tracks gum healt…

This study compares two ways to restore a full upper jaw with dental implants: placing the permanent teeth right away versus waiting 6 weeks. Researchers want to see which timing leads to better implant stability and patient satisfaction. 24 adults with healed upper jaw tooth los…

This study looks at how well different types of dentures and implant-supported dental devices help people chew and how they affect quality of life. Researchers will compare conventional dentures, mini-implant overdentures, and implant-assisted partial dentures in 240 adults. The …

This study looks at whether artificial intelligence can help dentists plan where to place dental implants in people who have lost all their lower teeth. Researchers will use old CT scans to compare AI-generated implant plans with plans made by expert dentists. The goal is to see …

This study compares two methods of making 3D-printed dentures: scanning directly inside the mouth versus scanning a traditional mold. Eight people with no teeth will try both types of dentures to see which one stays in place better. The goal is to find out if the newer, more comf…

This study looks at two different types of lower dentures held in place by dental implants in adults aged 60-70. The goal is to see which design distributes bite force more evenly and stays more securely in the mouth. Researchers will use special devices to measure bite balance a…

This study compares two techniques for placing dental implants in people with no teeth: fully guided (using a surgical guide) and partially guided. Sixteen participants will receive implants in both jaws, and researchers will measure how accurate the implant positions are and how…
