The Reliability of a Surgery-First Orthognathic Approach Without Presurgical Orthodontic Treatment for Skeletal Class III Dentofacial Deformity

Abstract

The surgery-first orthognathic approach without presurgical orthodontic treatment was found to be predictable and applicable to treat class III dentofacial deformities, and we recommend consideration of the technique as an effective alternative for treating this condition.

Facial asymmetry correction: From conventional orthognathic treatment to surgery-first approach

“…6 It is believed that the direction of orthodontic tooth movement after surgery is coordinated with muscular forces that accelerate tooth alignment and dental decompensation. 7 In addition, the regional acceleratory phenomenon (RAP) is activated by the Review Facial asymmetry correction: From conventional orthognathic treatment to surgery-first approach Tahereh Hosseinzadeh Nik 1 • Elahe Gholamrezaei 1 • Mohammad Ali Keshvad 1 * orthognathic surgery as part of the wound healing process and can play an important role in shortening of the treatment course. 8,9 Evidence shows that the serum level of alkaline phosphatase, which is a key enzyme in bone formation, increases as part of the RAP process four weeks after surgery, and its level remains high for up to four months postoperatively.…”

Surgery-First: A New Approach to Orthognathic Surgery

“…Although Surgery-First can be applied to both second and third Classes, different Authors agree that the majority of treated cases are Class III malocclusions associated with previously reported characteristics and it can be applied successfully to cases characterised by at least three occlusal stops, placed between the upper and lower teeth. Moreover, Choi et al (15) suggest that the Surgery-First approach achieves similar results to conventional orthognathic surgery, and it is a predictable treatment that can be easily applied to the skeletal Class III as a valid alternative to treat the above-mentioned conditions.…”

Current status of surgery-first approach (part III): the use of 3D technology and the implication in obstructive sleep apnea

“…The mandibular incisor will go for labioversion which is also in accordance with the dental decompensation procedures. Therefore, even after pre-operative correction, complete stability of post-operative occlusion cannot be obtained and evaluation of post-operative orthodontic treatment for stable occlusion should be accompanied [13].…”
