Study Comparing Three Impression Methods for 3D-Printed Mandibular Implant Overdentures in Adults

What this Trial Is About

Researchers are evaluating three different impression techniques for making 3D-printed mandibular implant overdentures in patients who have lost all their lower teeth. This randomized crossover trial involves sixteen patients aged 45 to 70 years who will receive two implants in the lower jaw. The study aims to compare how these techniques influence chewing efficiency and patient satisfaction. The three impression methods being studied are conventional open-tray implant-level impression, functionally generated reline impression, and mucostatic base with functional borders impression. Each participant will wear three different overdentures made using these techniques, each for three months. Between each overdenture period, there is a two-week washout phase during which a provisional denture is worn. The order of techniques is randomly assigned for each patient. Participants will undergo assessments at 3, 6, and 9 months after overdenture insertion. Chewing efficiency will be measured using a color-mixing ability test, and patient satisfaction will be recorded using a Visual Analog Scale. The study includes clinical evaluations and questionnaires to monitor the effects of each impression technique on both function and patient experience.
