Digitally Planned Static Guided Implant Placement for Posterior Mandibular Rehabilitation: Clinical Evaluation of Accuracy and Surgical Outcome

Abstract Computer-assisted implant surgery has transformed implant dentistry by improving the precision and predictability of implant placement through digitally guided workflows. Accurate three-dimensional positioning remains critical for achieving favorable biomechanical load distribution, prosthetic success, and long-term peri-implant stability. This report presents rehabilitation of a posterior mandibular edentulous site using a digitally planned static guided implant placement protocol. A 58 year old male patient presented with a missing mandibular first molar and reduced masticatory efficiency. Cone Beam Computed Tomography (CBCT) was performed for assessment of bone morphology and prosthetically driven virtual planning. A customized tooth-supported static surgical guide was fabricated to transfer digital planning to the surgical field. Following soft tissue punch removal and limited flap reflection for direct verification of guide accuracy, sequential osteotomy preparation was performed using a guided drilling protocol. A 4.5 × 8.5 mm implant fixture was inserted with primary stability of approximately 35 Ncm. Postoperative healing remained uneventful. Radiographic assessment confirmed accurate implant positioning and satisfactory relationship with adjacent anatomical structures. Successful osseointegration was observed at three-month follow-up. This case highlights the role of digital workflow-assisted static guided implant surgery as a predictable approach for improving implant placement accuracy in posterior mandibular rehabilitation.
