A Digital simulation of mandibular movements, B photograph.
Surgery of models was performed. The individual dental models were repositioned, simulating the movements of the mandible as represented by the digital prediction.
An acrylic intermediate occlusal splint was manufactured. Afterwards, the upper model was re-positioned in the semiadjustable articulator Figure 14A. Then the mandibular model was repositioned to oppose the upper model, simulating the final position of the occlusion during surgery.

Based on this position the final occlusal splint was made Figures 14 B-E. Surgical procedure.
Initially, the maxillary anterior segmentation from lateral incisor to lateral incisor was performed. In the mandible a bilateral sagittal osteotomy was conducted using surgical saws toper form a retraction of 5mm Figure 15 C.
An intermediate splint was used to secure the mandible in the correct position Figure 15 D.

Genioplasty would be carried out as a secondary procedure, if necessary, after post-surgical assessment of the scarring. During surgery mini-implants were placed to be used both for intermaxillary fixation due to the fact that during segmental osteotomy the archwires were cut as well as for the use of intermaxillary elastics for 30 days during the immediate postoperative phase to achieve maximum stability.

Active orthodontic treatment was resumed four weeks after surgery. The objective was to achieve ideal occlusal relationships, in terms of canine class, molar relationship, overjet, overbite, and matching dental midlines. Still accordingly to those previous authors [ 6 ] these individuals must constantly take into account the effect of their mismatched jaws in everyday things such as what they can eat in public without embarrassment or whether they will be considered stupid, mean, or angry when they meet others just because of their facial appearance.
It also has been declared that patients with DD are at a disadvantage in society due to low self-esteem and decreased levels of confidence, as well as associated physiological problems [ 7 ].
These important impacts in life aspects such as oral function, appearance and interpersonal relationships were also evidenced by others [ 4 , 8 , 9 ]. The study also aimed to explore gender and age differences through those instruments.
A convenience sample of 53 consecutive subjects with DD were interviewed while searching for dental treatment, orthodontic treatment or searching for specific treatment for DD.
The diagnosis for DD followed the standard literature concepts [ 6 ] and were made exclusively by orthodontists or maxillofacial surgeons invited. All perssonal enrolled in this research received full instructions concerning the methods. Cephalometric analysis was performed only for patients who were enrolled into presurgical orthodontic treatment.
Clinical diagnosis of mandibular prognathism, mandibular retrognathism, anterior open bite, laterognathism, vertical maxillary excess or a combination of these health problems were made and the patient were asked to participate and answer the questionnaires after a full explanation of the objectives of the research.
Previous orthognathic surgery, syndromes or congenital deformities such as cleft lip and palate, trauma sequel and edentate patients were excluding criteria. Instructions about how to answer the questionnaires were given to the patients and any doubt over the questions could be solved by a researcher assistant.
The 22 items are divided into concerns or domains regarding as social aspects of deformity first component , facial aesthetics second component , oral function third component and awareness of facial deformity fourth component.
The scoring of the OQLQ is performed by addition of individual items within the domains.
A total OQLQ score can range from 0 to 88, with domains counting specifically social aspects domain, 0 - 32; dento-facial aesthetics domain, 0 - 20; function domain, 0 - 20; and awareness of dento-facial aesthetics, 0 - The OHIP questionnaire is a question instrument developed by Slade and Spencer [ 12 ] and was conceived to measure how different oral conditions affect quality of life in an overall sense.
The OHIP domains range from 0 - 40 and the values are obtained through a weighted average of the questions which compose each dimension. Higher scores indicate a worse oral health-related quality of life state [ 13 ].The information about the effect of orthognathic surgery on patients during the recovery phase enables surgeons to better inform patients on their expectations from surgery [ 13 ].

PART 3: Wakae et al10 reported the extraction and syndactyly of fingers reduce the ability to obtain good of maxillary right canine, maxillary left lateral incisor and oral hygiene, causing greater dental plaque and periodontal maxillary left second premolar since they were in ectopic problems. The information about the effect of orthognathic surgery on patients during the recovery phase enables surgeons to better inform patients on their expectations from surgery [ 13 ].
This study has been conducted in full accordance with the World Medical Association Declaration of Helsinki. Outcomes and Special Considerations p. In most cases, they are the result of moderate or severe genetic distortions of the normal development process such as mandibular prognathism, bimaxillary prognathism or retrognathism, maxillary vertical excess and should be corrected using an integrated treatment of orthodontics and orthognathic surgery in adult orthodontic [ 2 ].
