Internally Irrigated and Externally Irrigated Surgical Guide Design for Placement of Dental Endosseous Implants

Background: Patient specific surgical guides (PSG) have been widely used to achieve a precise 3D implant position. However, they prevent external cooling systems from reaching the osteotomy site sufficiently. So, heat generated during guided implant surgery is greater than free hand technique. Adding internal irrigation channel to the conventional surgical guides allows better diffusion of irrigation to the osteotomy site and reduces heat generation. Aim of the study: Is to introduce a patient specific surgical guide design with internal irrigation system and compare it to the conventional surgical guide with external irrigation clinically through bone temperature, implant stability and radiographically by CBCT through crestal bone loss and bone density.
