Artificial intelligence for treatment planning and soft tissue outcome prediction of orthognathic treatment: A systematic review

Abstract

Background: The accuracy of artificial intelligence (AI) in treatment planning and outcome prediction in orthognathic treatment (OGT) has not been systematically reviewed. Objectives: To determine the accuracy of AI in treatment planning and soft tissue outcome prediction in OGT. Design: Systematic review. Data sources: Unrestricted search of indexed databases and reference lists of included studies. Data selection: Clinical studies that addressed the focused question ‘Is AI useful for treatment planning and soft tissue outcome prediction in OGT?’ were included. Data extraction: Study screening, selection and data extraction were performed independently by two authors. The risk of bias (RoB) was assessed using the Cochrane Collaboration’s RoB and ROBINS-I tools for randomised and non-randomised clinical studies, respectively. Data synthesis: Eight clinical studies (seven retrospective cohort studies and one randomised controlled study) were included. Four studies assessed the role of AI for treatment decision making; and four studies assessed the accuracy of AI in soft tissue outcome prediction after OGT. In four studies, the level of agreement between AI and non-AI decision making was found to be clinically acceptable (at least 90%). In four studies, it was shown that AI can be used for soft tissue outcome prediction after OGT; however, predictions were not clinically acceptable for the lip and chin areas. All studies had a low to moderate RoB. Limitations: Due to high methodological inconsistencies among the included studies, it was not possible to conduct a meta-analysis and reporting biases assessment. Conclusion: AI can be a useful aid to traditional treatment planning by facilitating clinical treatment decision making and providing a visualisation tool for soft tissue outcome prediction in OGT.

AI in Orthodontics: Revolutionizing Diagnostics and Treatment Planning—A Comprehensive Review

“…These limitations stem from the lack of strict guidelines, which results in a heavy reliance on expert decisions and opinions. A systematic review conducted by Smith et al [154] further supports this notion by indicating that the results of current studies cannot be easily generalized due to their significant heterogeneity. The authors carefully concluded that AI might be a useful tool in planning orthognathic surgery.…”

“…This leads to a heavy dependence on expert decisions and opinions. A systematic review by Smith et al [154] further highlighted the significant heterogeneity among current studies and the difficulty in generalizing their results. The authors cautiously concluded that AI could be a valuable tool in orthognathic surgery planning, but further research is necessary.…”
