Three-dimensional analysis of palatal shape in patients treated with SARME using traditional and geometric morphometrics

摘要: Structured Abstract Objectives To demonstrate the advantages of dense surface models in evaluation surgical-assisted rapid maxillary expansion's effect (SARME) on palatal morphology. Furthermore, we compared before (T1) and after (T2) therapy with controls. Setting Sample Population Surgical-assisted group 15 adult patients (Le Fort I midpalatal sagittal osteotomy, hyrax screw) 50 individuals. Patients were treated General Faculty Hospital, Prague. Materials Methods Eighty plaster casts digitized using a three-dimensional laser scanner evaluated traditional geometric morphometrics. Results An unpaired Student's t-test controls SARME T1 revealed significant differences all width measurements. Between T2 group, only related to interdental angle between first molars particularly height. The most remarkable pre- post-treatment morphology widening dental arch buccal shift lateral teeth associated apparent flattening alveolar crest. Conclusions Dense model provided descriptive visualization treatment was helpful shape variability including detection difficult patients. Correction discrepancy by successfully achieved. After therapy, comparable control group.
