Abstract
Background
Digitally customized abutments are increasingly used in contemporary implant prosthodontics.
Purpose
This systematic review and meta‐analysis aimed at comparing the peri‐implant clinical outcomes of digitally customized and prefabricated abutments.
Materials and methods
The search strategies included electronic databases (PubMed, Embase, Scopus, and Cochrane clinical trials database) and related journals up to September, 2020. A qualitative and quantitative synthesis was performed on data extracted from the included studies.
Results
Three RCTs (number of patients = 120; number of dental implants = 120) and two prospective cohort studies (number of patients = 144; number of dental implants = 144) with one to three‐year follow‐up periods were included. The quantitative analyses did not demonstrate a significant difference between digitally customized and prefabricated abutments for peri‐implant pocket depth (P = 0.62), plaque index (P = 0.67), bleeding on probing (P = 0.43), keratinized mucosa width (P = 0.75), and pink aesthetic score (P = 0.30) at one‐year follow‐up visit. The qualitative analyses for marginal bone level change, calculus accumulation, implant survival rate, implant success rate, white aesthetic score, and patient‐reported outcomes did not demonstrate a significant difference between two groups during 1 to 3‐year follow‐up visits.
Conclusion
The current data do not provide evidence of significant differences between two abutment fabrication methods in terms of peri‐implant clinical outcomes within short‐term period (CRD42020170807).
