Orthodontic consideration in Orthognathic surgery-A review
Skeletal malocclusions are one of the common problem encountered in today's orthodontics. Treatment of such skeletal deformities requires combination of orthodontic and surgical treatment. The treatment does not change only the bony relations of the facial structures, but soft tissues as well, and by doing so, may alter the patient's appearance. However, longer treatment times and transitional detriment to the facial profile has led to a new approach called " surgery-first, " which eliminates the presurgical orthodontic phase. After the jaws are repositioned, the orthodontist is then able to properly finish the bite into the best possible relationship. Surgery may also be helpful as an adjunct to orthodontic treatment to enhance the long term results of orthodontic treatment, and to shorten the overall time necessary to complete treatment.
Orthodontic Management of Dentofacial Skeletal Deformities

The treatment of complex malocclusions with overriding skeletal discrepancies requires an exceptional amount of pretreatment planning. The roles of the orthodontist and the surgeon are equally important. Sufficient input from each member of the orthognathic surgical team is ...

Dentofacial deformities are corrected by orthognathic surgery and there are two approaches: orthodontics-first approach and surgery-first approach. In orthodontics-first approach, the orthodontic treatment precedes the orthognathic surgery, whereas in the surgery-first approach, the orthognathic surgery precedes the orthodontic treatment. Surgery first orthognathic approach [SFOA] is defined as orthognathic surgery without presurgical orthodontics.Compared to conventional surgery, SFOA reduces the overall treatment time, achieves immediate aesthetics and adequate postoperative stability in selected cases. In SFOA, treatment time canbe substantially reduced by eliminating the presurgical phase and taking advantage of regional accelerated phenomenon for postsurgical orthodontics. SFOA is a good alternative to conventional orthognathic surgical procedures in skeletal malocclusion cases [especially in Class III and asymmetry patients]. A team approach between surgeons and orthodontists is vital for successful outcomes with SFOA. Thus, with the advent of SFOA, there is a paradigm shift in the traditional orthognathic approach. This article discusses about the indications, contraindications, advantages, disadvantages and relapse rate of SFOA, impact of regional acceleratory phenomenon on postsurgical orthodontics, and delineates the differences between SFOA and conventional orthognathic approach in the correction of dentofacial deformities.
Dentofacial Deformity: Treated with Combined Orthodontic and Orthognathic Surgery Treatment
Saudi Journal of Oral and Dental Research
Scope: Orthognathic surgery with pre-surgical and post-operative discussion is highest degree received procedure for rectifying of inadequate with dento-alveolar malocclusion. Nevertheless, recent advancements in pre-surgical orthodontic pretence and postsurgical orthodontic treatments utilise mini screws have exhibit noteworthy constancy and dominance of the occlusion after orthognathic surgery. Therefore, we have espouse a surgery-first orthognathic overture unaccompanied preoperative surgery, founded on a new presurgical simulation outgrowth employ a orthodontist version. Objectives: Through initiate recently developed protocol-named Anticipated Benefit-and into depict it near an analytic sheath. Methods: The outlining phases are given and formerly exemplified beyond evaluate a tolerant with a Class III malformation. According to that technique, later a little attentive outlining orthodontic instrument is rigid and later corrective jaw surgery is carry out. Conclusions: The surgery-first orthognathic access outwardly pre-operative identic therapy was detect to be predictable and applicative to treat class III dentofacial deformities, and we commend circumstance of the technique as an efficacious option for treating this stipulation.
Important Orthodontic Considerations in Preparation of Orthognathic Surgical Cases
Taiwanese Journal of Orthodontics, 2022
Nowadays some adult patients seeking for orthodontic treatment may present severe malocclusion associated with pronounced skeletal discrepancies. Accordingly, thorough consideration and planning would be beneficial for the patient by the combined efforts of orthodontic and orthognathic approaches. This review reiterated the genetic impact on the growth velocity of the jaw with age in Class III malocclusion, and outlined the treatment protocol for the steps including the initial evaluation, the diagnosis, and the alignment of the teeth and dental arches before and after surgical correction. Specifically, emphasis is addressed on how to obtain records of jaw relationship in centric relation (CR) position. Moreover, the combined efforts in correcting the dental and skeletal Class II jaw discrepancy were defined and discussed.
Versatility of orthognathic surgery in the management of maxillofacial deformities

Orthognathic surgery is a surgical procedure which is widely practiced throughout world for the correction of various maxillofacial deformities. The procedure for correction of a particular deformity will be done after proper evaluation, which includes cephalometric and dental model analysis and photographs. The patient undergoes pre surgical orthodontic correction for the dental compensation after which the surgery is planned.

The exact prevalence of significant dentofacial deformities that requires orthognathic surgery as a part of definitive treatment is not quite clear. [1] However, looking at the information collected about the severe and extreme forms of malocclusions (overjet> 7mm, reverse overjet> 3 mm, openbite > 3 mm) it can be estimated that about 5% of the UK or USA population present with dentofacial deformities that need orthognathic surgery as a part of their definitive treatment. [1,2] The estimated prevalence associated with a degree of underestimation because of the compensated malocclusions in patients with dentofacial deformities. [1] Orthognathic surgery describes several surgical procedures on either or both of the mandible or maxillae to realign the jaws into a more acceptable (normalized) or functional relationship. This often includes a course of orthodontic treatment before and after orthognathic surgery. Patients with dentofacial deformity frequently present with facial asymmetry and previous reports indicate that about 21%-67% of patients with prognathia or retrognathia had facial asymmetries, [3-6] with the chin deviation being the most remarkable feature of asymmetry. [4] In one study, deviation of the lower face was more common, and greater in length than that of the upper face (5%) as well as the middle face (36%), [7-9] and 74% of asymmetrical orthognathic patients had chin deviation. [4] According to Farkas, the incidence of periocular asymmetry was <2% in the normal population, and the periocular tissues were more symmetric than the nose (7%) or mouth (12%). [10,11] Information regarding the prevalence of surgical osteotomies used for dentofacial deformities in Iran is lacking, and therefore, the aim of the present study was to assess, retrospectively, the type of orthognathic surgeries and dentofacial deformities treated
