ABSTRACT
Abstract Objective: To use virtual computer-assisted planning in orthognathic surgeries through meta-analysis and systematic review. Material and Methods: This search took place between 2010 and 2019. The databases searched in this domain included MEDLINE, PubMed, Cochrane Library, Embase, ISI, and Google scholar. Accordingly, the abstracts of the articles were initially reviewed and the ones that had the most coordination with the study objectives were selected. Then, the full texts of the articles were examined; and finally, five studies were selected. In addition to reviewing the related literature, the results were extracted and entered into the meta-analyzer Stata V.14 to summarize the final results. Results: The sample size in this study was at a range from 6 to 28 patients and a total number of 85 patients had participated in the given investigations. As well, CT and CBCT were selected as imaging methods. Clinical imaging and analysis were also employed in computer-assisted planning in all five studies. Subsequently, surgical planning was performed and the virtual splint was designed while the planning time was 225 minutes and 145 minutes in two studies. Conclusion: The present results supported computer-assisted planning and the quality of scientific evidence.
