Traditional orthognathic surgery has long been performed after presurgical orthodontic treatment. Despite some concerns, the surgery-first orthognathic approach (SFOA) or surgery-first approach (SFA) without presurgical orthodontic treatment has gradually gained popularity. In recent years, several articles dealing with the concepts of the SFA have been published worldwide. However, the SFA has not yet been standardized, and many surgeons use slightly different protocols and concepts. This review article discusses the beginning and evolution of the SFA and its current concepts, including some opinions based on the authors' clinical experiences over the last 15 years. According to recent investigations, the SFA could be applied effectively in several situations including class III malocclusion, class II malocclusion, and facial asymmetry. However, debate on the SFA continues and many issues remain to be resolved. This review article addresses the current issues regarding the SFOA, including its advantages and disadvantages, as well as its indications and contraindications. The authors summarize various aspects of the SFA and expect that this review article will help surgeons and orthodontists better understand the current status of the SFA.

Orthognathic surgery has steadily evolved, gradually expanding its scope of application beyond its original purpose of simply correcting malocclusion and the facial profile. For instance, it is now used to treat obstructive sleep apnea and to achieve purely cosmetic outcomes. Recent developments in three-dimensional digital technology are being utilized throughout the entire process of orthognathic surgery, from establishing a surgical plan to printing the surgical splint. These processes have made it possible to perform more sophisticated surgery. The goal of this review article is to introduce current trends in the field of orthognathic surgery and controversies that are under active discussion. The role of a plastic surgeon is not limited to performing orthognathic surgery itself, but also encompasses deep involvement throughout the entire process, including the set-up of surgical occlusion and overall surgical planning. The authors summarize various aspects in the field of orthognathic surgery with the hope of providing helpful information both for plastic surgeons and orthodontists who are interested in orthognathic surgery.

This case report describes the treatment of an adult female patient with a history of periodontal disease, Class I malocclusion with extrusion, dental spaces, and pathologic tooth migration. The patient was treated with clear aligners, which effectively controlled the strength and direction of orthodontic forces after 3 months of systematic periodontal treatment. The Peer Assessment Rating (PAR) index was calculated from study models before and after treatment. The pretreatment PAR score was 24, and the posttreatment PAR score was 4. The PAR score for this patient changed by 83%. Satisfactory appearance and good function were achieved for this patient.

Purpose: This study examined the factors influencing the choice of dental clinics by individuals who received orthodontic treatment for malocclusion. Methods: Participants were 320 male and female college students in Daegu and Gyeongsangbuk-do who had received orthodontic treatment in dental clinics for malocclusion. They were surveyed about their choices of dental clinics. Of the 320 questionnaires, 294 (91.9%) were used for analysis, and surveys with insufficient responses or errors were excluded. Results: The factors influencing the choice of dental clinics varied among the participants. Furthermore, factors that most commonly affected their choices were, in order, trust in dentists' skills and medicine used, information from community sources, friendliness of the dentist, friendliness of clinic staff, cleanliness of the hospital, availability of up-to-date medical facilities and equipment, convenience of location, and recommendations by acquaintances. Conclusion: Factors underlying the choice of dental clinics varied among the participants. Typically, these choices were strongly influenced by factors such as reputation, professionalism, and friendliness.

This report presents a case of successful treatment of skeletal Class III malocclusion with transverse discrepancy in adult by surgery-first approach. Traditionally dental decompensation is necessary prior to surgery in 2-jaw surgery to correct transverse and rotational discrepancy. However, the hyrax-type palatal expansion appliance was used to improve maxillary expansion accuracy and postoperative stability in this surgery-first approach (segmental Le Fort I osteotomy and mandibular setback surgery). It was established to be an effective means of precisely predicting postoperative occlusion and achieving stable retention after surgery of skeletal Class III malocclusion with maxillary transverse discrepancy.
