The application of retromolar mini-screws for distalization in preparation for orthognathic surgery: A case series

Combined orthodontic-surgical treatment is often chosen by clinicians and patients to enhance both skeletal and occlusal relations in cases of moderate to severe jaw discrepancies. Presurgical orthodontic preparation is crucial for achieving arch coordination and eliminating dentoalveolar compensation. Three cases with varying dental and skeletal characteristics are presented, one with protruded mandible and Class III relationship, the second with maxillary vertical excess and retruded mandible, and the third with retruded mandible. Distalization using retromolar skeletal anchorage for molar distalization was employed to achieve arch coordination and eliminate dentoalveolar compensation. The final outcomes demonstrated a harmonious occlusion with ideal interdigitation and a well-balanced facial profile. In cases with a favorable initial arch coordination that require space for incisor decompensation or crowding relief, distalization becomes a preferred strategy. Retromolar screws provide an advantageous force vector, facilitating efficient retraction of the entire dental arch.
