There is not enough strong evidence to say that OD is better than CD in the long term. More randomized clinical trials (RCTs) with standardized protocols and longer follow-up periods are recommended. Additional long-term, well-designed comparative human studies are needed to declare the advantages and disadvantages of the OD technique vs. the CD technique. There was some heterogeneity across sites, gender, duration of follow-up, implant system, and operator, but not affect the comparability and generalizability of this meta-analysis.
