What this Trial Is About
This randomized crossover clinical trial aims to compare three different impression techniques for the construction of 3d-printed mandibular implant overdentures in completely edentulous patients. Sixteen patients will receive two mandibular implants and three overdentures fabricated using:(1) conventional open-tray implant level impression (2) functionally generated reline impression, and (3)mucostatic base with functional borders impression. Each overdenture will be worn for three months with a washout period between interventions. The primary outcome is masticatory efficiency, assessed using a color -mixing ability test at 3,6, and9 months. Secondary outcome is patient satisfaction, assessed using a Visual Analog Scale (VAS) at the same intervals. the study hypothesis is that the impression technique influences both chewing efficiency and patient satisfaction
