3D-Printed PLA Guide Versus Resin Guide in Mandibular Molar Implant Placement
Sponsor: Mohamed Esmail Ahmed Hassan
Summary
This randomized clinical trial compares two tooth-supported computer-guided surgical guide systems for immediate implant placement in mandibular molar extraction sockets: a patient-specific 3D-printed PLA guide system and a modified resin guide system. The study evaluates implant positioning accuracy, primary implant stability, and surgical time.

Interventions
immediate implant placement using PLA guide
Preoperative virtual planning was performed using CBCT data and digital intraoral scans. The datasets were used for prosthetically driven implant planning and fabrication of a patient-specific 3D-printed PLA surgical guide. Following atraumatic tooth extraction and socket preparation, the guide was seated and osteotomy preparation was performed through the guiding channel according to the planned implant position and trajectory. The implant was then immediately inserted. Primary implant stability was assessed using an Osstell device and Implant Stability Quotient (ISQ) measurements.
