The aim of this review is to evaluate the evidence for the diagnostic efficacy of 3D cephalometry for orthodontic diagnosis and treatment planning.
PubMed, EMBASE and the Cochrane library were searched comprehensively using specific search strategies. Two reviewers read the retrieved articles and selected relevant publications based on pre-established inclusion criteria. The data was then extracted into protocol 1 and protocol 2, which were based on the Quality Assessment of Diagnostic Accuracy Studies (QUADAS) tool. Next, levels of evidence were categorized into 3 groups: low evidence, moderate evidence and high evidence. Finally, the results were descriptively analysed.
Five hundred and seventy-one publications were found by using specific search strategies and 50 additional studies were found by the hand search. A total of 35 publications were included in this review. Based on our analysis limited evidence for the diagnostic efficacy of 3D cephalometry was found. Only 5 studies were found to provide a moderate level of evidence. Accordingly, this review reveals that there is still need for methodological standardized studies on 3D cephalometric analysis.
