Abstract
Introduction: The extent of improvement in accuracy of orthognathic surgery depend on many factors such as used technology, type of orthognathic surgery and patients' characteristics. This article aimed to review the literature regarding the accuracy of virtual planning using three-dimensional computer assisted technology in bimaxillary orthognathic surgery.
Methods: The electronic MEDLINE search was conducted and the resultants studies were subjected into two types of screening, to identify eligibility. The primary screening was done based on abstracts of the articles and secondary screening based on the full texts of primarily eligible article. The articles should meet the inclusion criteria of being human in-vivo study, aimed to evaluate accuracy of virtual planning of hard tissue in bimaxillary surgery using 3-dimensional and computer assisted technology.
Results: The electronic search resulted in 39 studies which have been subjected for primary and secondary screening when 11 studies met the inclusion criteria. The accuracy of virtual planning was found accurate when compared to the postoperative results in five included studies, while no significant results found in three included studies.
Conclusion: There was a satisfactory accuracy of virtual planning using 3-dimensional and computer-assisted technology in conduction of bimaxillary orthognathic surgery. In particular, when a combination of 3-dimensional scanning, CBTC imaging and surgical splint guiding were used.
