One-abutment one-time insertion and related outcomes

: a systematic review of the literature with meta-analysis

Abstract

Background: The one-abutment one-time (OAOT) insertion protocol is an emerging approach in implant dentistry, that aims to simplify the rehabilitation procedure compared to conventional protocol. This systematic review with metaanalysis synthesizes the current literature on OAOT insertion, evaluating its effects on clinical outcomes such as survival rates, success rates, and periimplant indices such as Marginal Bone Loss (MBL) to conventional protocol. Materials and Methods: This study was registered on the PROSPERO platform and carried out in compliance with the PRISMA statement for systematic reviews. A thorough electronic search was conducted in two primary databases Medline/PubMed and CochraneDatabase focusing specifically on RCTs spanning from 2010 to 2024 to identify pertinent literature. Each identified article underwent meticulous analysis, and inclusion or exclusion was determined based on pre-established standards. Results: Eleven RCTs with minimum follow-up period of 4 months were selected (550 patients and 830 implants). Notable variances were observed in MBL at 6 and 12 months, favoring the test group. Conclusions: The OAOT protocol demonstrates a discernible impact on clinical outcomes within the short to medium term, particularly regarding variables like MBL that are indicative of the sustained success of implants.
