Abstract: Objective To explore the exposure rate of customized titanium mesh and traditional titanium mesh after guided bone regeneration(GBR) and the time point of soft tissue dehiscence, and to provide clinical reference for GBR. Methods Databases, including PubMed, EMbase, Web of Science and Cochrane Central Register Controlled Trials, were searched by two independent researchers, for published articles on titanium mesh exposure after GBR. This study selected English articles published from January 1st, 2011 to December 31th, 2021. Stata 16.0 software was used to systematically analyze the research data that finally met the inclusion criteria. Results A total of 962 articles were found, and 9 of which were quantitatively analysed. The combined value of the total exposure rate of titanium mesh was 0.37(95%CI=0.31~0.42). The result of subgroup analysis showed that the combined value of the customized titanium mesh exposure rate was 0.20(95%CI=0.13~0.27) and the combined value of the traditional titanium mesh exposure rate was 0.60(95%CI=0.52~0.68). Conclusion The exposure rate of customized titanium mesh is lower than that of traditional titanium mesh, which is of great significance to provide sufficient grafting space for accurate bone reconstruction in GBR.
