Abstract

Abstract: Objective: To evaluate the clinical outcome of implant-supported rehabilitation of maxillary incisors using angulated screw channel (ASC) abutment with or without simultaneous GBR. Methods: Fifteen patients with fifteen implants placed in anterior maxilla restored with ASC abutment were followed up for six months. The cumulative survival rate, bone resorption around implants, peri-implant soft tissues, and esthetics were analyzed through X-ray, clinical examination, and patient satisfaction investigation. Results: After an average follow-up of 6 months, the implant cumulative survival rate was 100%. The mesial and distal marginal bone loss of implants was 0.447±0.121mm and 0.355±0.127mm, respectively. Peri-implant soft tissues achieved satisfactory outcome and 93.3% patients were satisfied with the restoration. Conclusion: The implant-supported rehabilitation of maxillary incisors using ASC abutment is a minimally invasive and simplified therapeutic schedule with a certain clinical application value.
