Comparative Study Between Fabricated Surgical Guides And Using Roots Of Molar Teeth As A Guide In Immediate Implant Placement In Fresh Extraction Socket: Prospective Clinical Study

Aim of study : The aim of the study was to compare between fabricated surgical guides and using roots of molar teeth as a guide in immediate implant placement in terms of Stability and Accuracy. Patients and Methods: A prospective clinical study was used in this investigation. 20 patients were divided into two groups: 10 immediate implants were inserted in group (A) study group using interradicular bone drilling between roots of molar teeth, and 10 immediate implants were placed in group (B) using prefabricated surgical guide, CBCT done immediately postoperative to evaluate implant accuracy, Osstell was utilized to ascertain the intraoperative primary stability and secondary stability six months later. Results: 18 implants were successfully functioning in both groups (A,B), For implant accuracy, there was no statistical significance between two groups (A,B) . Also for the implant stability, there was no statistical significance between two groups (A,B). Conclusions: Interradicular bone drilling teqnique increases implant position accuracy, stability, and operation feasibility very similar to prefabricated surgical guide, which demonstrated only slight increase in Stability and Accuracy. keywords: Immediate implant placement, intraradicular drilling technique, conventional. fabricated surgical guides.Running title: Various methods for immediate posterior mandibular implants.
