Single _ Drill Vs Full Sequence Guided Implant Placement

This randomized clinical trial aims to compare the accuracy of single-drill (pilot-guided) computer-guided implant surgery versus full-sequence computer-guided dental implant placement. The study evaluates clinical and radiographic outcomes, focusing on apical, angular, coronal, and depth linear deviations using post-operative cone-beam computed tomography (CBCT) superimposition.

Inclusion Criteria: Age \> 18 years, both sexes. Patients requiring dental implant placement in the posterior region (molar area). Patients systemically healthy with no medical history contraindicating implant surgery. Sufficient inter-arch space for future prosthesis (minimum 7 mm). Exclusion Criteria: Bone height \10 cigarettes/day). Alcohol or drug abuse. Pregnancy. Local or systemic infection. Uncontrolled metabolic disease (e.g., diabetes mellitus). Severe hepatic or renal dysfunction. Chemotherapy or radiotherapy within the last 5 years. Immunosuppression therapy or autoimmune disorders. Complete edentulism. Pathological conditions such as periapical or periodontal abscesses. Untreated gingivitis or periodontitis.
