Computer Guided Immediate Implant Placement in Mandibular Molars Using Patient Specific 3D Printed Polylactic Acid Graft Versus Conventional Immediate Implant Placement With Xenograft

Sponsor: Mahmoud Fawzy Mahmoud Mohamed

Summary

This randomized controlled clinical trial will evaluate a computer-guided immediate implant placement technique in non-restorable mandibular molars using a patient-specific 3D-printed polylactic acid (PLA) graft and implant position guide, compared with conventional immediate implant placement using xenograft for grafting of the jumping gap. Eligible patients requiring extraction and immediate implant placement in mandibular molars will be randomly allocated to either the PLA-guided intervention group or the conventional treatment group. In the intervention group, a patient-specific 3D-printed PLA graft and guide will be designed from preoperative CBCT data and used to guide implant placement in the digitally planned position. In the control group, immediate implant placement will be performed using the conventional protocol with xenograft grafting. The study will assess the primary stability of the dental implant and the accuracy of implant placement compared with the digitally planned position. Implant stability will be measured using the Osstell device, while implant position will be evaluated by superimposing the immediate postoperative CBCT scan on the preoperative CBCT using Blue-Sky Plan software. Patients will be followed clinically after surgery, with follow-up visits during the healing period and a six-month postoperative CBCT evaluation before implant loading.
