The influence of crown-to-implant ratio in single crowns on clinical outcomes: A systematic review and meta-analysis
A consensus about the effect of crown-to-implant (C/I) ratio in single crowns regarding the implant survival rate and marginal bone loss (MBL) is lacking.

| description | A consensus about the effect of crown-to-implant (C/I) ratio in single crowns regarding the implant survival rate and marginal bone loss (MBL) is lacking.
The purpose of this systematic review and meta-analysis was to evaluate the influence of C/I ratio in implant-supported single crowns on clinical outcomes.
The search was made in the PubMed/MEDLINE, Scopus, and the Cochrane Library databases following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria and registered with the International Prospective Register of Systematic Reviews (PROSPERO: CRD42018095711). The focused question was “Does the crown-to-implant ratio influence clinical outcomes for implant-supported single crowns?”
Five direct comparative studies were included (C/I ratio ≤1 or >1, or ≤2 or >2), including a total of 262 participants with a mean age of 54.5 years. The meta-analysis comparing C/I ratio between ≤1 or >1 revealed no significant differences (P=.18; risk difference:-0.05; 95% confidence interval: -0.11 to 0.02) in terms of implant survival rate; the same was true for C/I ratio between 1 (0.07 mm [-0.29 to 0.22]); |

The mean MBL was calculated based in the qualitative data for each C/I ratio: ≤1 (0.15 mm [-0.34 to 0.34]); >1 (0.07 mm [-0.29 to 0.22]); <2 (1.32 mm [0.38-0.9]); and ≥2 (1.37 mm [-0.02 to 0.91]). The qualitative data reported that the most common mechanical complication was screw loosening, and the most common biological complication was peri-implantitis.
The meta-analysis revealed no relationship between categories of C/I ratio for implant survival rate. The qualitative data also suggested that MBL increased as the C/I ratio increased.</description><identifier>ISSN: 0022-3913</identifier><identifier>EISSN: 1097-6841</identifier><identifier>DOI: 10.1016/j.prosdent.2020.06.010</identifier><identifier>PMID: 32948311</identifier><language>eng</language><publisher>United States: Elsevier Inc</publisher><subject>Crowns ; Dental Implants ; Dental Prosthesis Design ; Dental Prosthesis, Implant-Supported ; Dental Restoration Failure ; Humans ; Middle Aged</subject><ispartof>The Journal of prosthetic dentistry, 2021-10, Vol.126 (4), p.497-502</ispartof><rights>2020 Editorial Council for the Journal of Prosthetic Dentistry</rights><rights>Copyright © 2020 Editorial Council for the Journal of Prosthetic Dentistry.
