Radiographic Assessment of Bone Changes Around Implants Placed using Computer-Guided Approach with Single Drilling Protocol: A Randomised Clinical Trial

Objectives: The aim of this randomized prospective study was to evaluate and compare peri-implant radiographic bony changes following computer-guided osteotomy preparationusing novel single drill design versus conventional drilling technique. Materials And Methods: A total of 51 patients with maxillary single missing teeth prepared for implant placement using computer-guided template (CGT) in conjunction with either traditional sequential drilling approach (Group I, 26 patients) or single drilling approach (Group II, 25 patients). Seven days post-operatively, the patients expressed the degree of pain; and 6 months after surgery, marginal bone (MB) loss was evaluated radiographically for both groups. Results: Single drill approach showed significantly reduced MB loss and minimal post-operative pain when compared to sequential drilling approach Conclusion: Within the present study limitations, results concluded that preparation of osteotomy site using CGT with single drill approach demonstrated better conditions regarding peri-implant bony tissue,postoperative pain and reduce the surgical time.
