A Retrospective Clinical Evaluation Of Narrow Diameter Implant Supported Dental Prosthesis: Early Results

Abstract

Background: Narrow-diameter implants are planned for specific clinical conditions as locator implants between adjacent teeth with a narrow bone width or with only a narrow area in between. They are especially advantageous when restoring narrow teeth like lateral maxillary and mandibular incisors and first premolars. Methods: In the period between 2018 and 2019, 21 patients were rehabilitated with implant treatment. A total of 32 implants were placed (The Straumann® Bone Level Tapered Implants, ∅ 2.9 mm). The survival rates of the implants were analyzed and prosthetic complications were evaluated. Results: The accumulative 36-month survival rate of the implants was 96.9%. Prosthetic complications were mainly limited to loosening occlusal screws. No implant abutment fractures, screw fractures, or porcelain chipping were observed. Conclusion: The results show that narrow implants provide satisfactory treatment outcomes. Narrow implants can be preferred in cases, where the dental operation area is not wide enough.
