Abstract :Aim: The volume of the edentulous crest and its proximity to critical anatomical structures are important limiting factors for implant surgery. Surgical procedures with complications can be avoided by placing angled implants. The aim of this clinical study was to evaluate marginal bone loss and the complications of angled implants. Materials and Methods: Fifty-eight dental implants were examined in 32 patients (16 females, 16 males) with cone beam computed tomography (CBCT) images from patients with angled implants and complete edentation. The marginal bone loss in angled implants that were functional for 15 to 30 months was evaluated according to factors such as implant angle, connection type, opposing arch restoration type and planning of superstructure restoration. Marginal bone loss measurements were recorded from CBCT sections. Results: It was determined that 3.44% of the implants placed had an inclination of less than 15°, 75.86% had an inclination between 15° and 30° and 20.68% had an inclination of more than 30°. While there was no marginal bone loss on the mesial and distal surfaces, the average marginal bone loss was 0.66 on the buccal surfaces and 0.93 in the lingual region. Only one of the implants examined failed. No pain or infection was observed in any of the implants examined. Conclusion: According to the results of this retrospective clinical study, further clinical studies with larger sample sizes are needed to evaluate angled implants supported by full arch fixed prostheses as a predictable and valid treatment method in the prosthetic rehabilitation of edentulous jaws.
