Commentary

Orthodontic preparation for surgery is totally different from odontology correction alone action of optimum facial esthetics needs integrated cooperation of orthodontists and external body part surgeons. Routine operative dental medicine involves dental alignment, tooth decompensation, and arch coordination for the aim of getting most intercuspal interdigitation. Once the jaws area unit surgically aligned the aims of presurgical treatment area unit to decompensate lower and higher incisors. Generally these corrections can build the upset look worse presurgically, however it will show truth magnitude of the skeletal downside so permitting an optimum correction at surgery.

To add up, the steps in odontology preparation for orthognathic surgery area unit is to align arches one by one, accomplish compatibility of the arches or arch segments, and establish the right anteroposterior and vertical position of the incisors.

Dental alignment

Dental state of affairs, spacing, placement and rotations of the teeth ought to be corrected before orthognathic surgery. The key's to urge the teeth in correct position and angulation. During this part of the treatment, extractions could be required to alleviate moderate to severe state of affairs and build required house for teeth alignment. Extraction may also facilitate take away dental compensations. It ought to be taken into thought that extraction ought to be avoided if the house of the jaw permits favorable dental alignment. Tooth inclination, crowding, variety of upset and surgical operation area unit among the crucial factors when deciding that teeth ought to be extracted.

Most severe skeletal jaw discrepancies area unit partially remunerated. This natural phenomenon called “dentoalveolar compensation” may be a system that tries to take care of traditional interarch relationship. Compensations is dental or skeletal in nature. Dental compensations is vertical, thwartwise and or mesial. For instance at II skeletal malocclusions the higher anteriors retrocline to catch up on jaw prognathism and lower incisors procline to catch up on inframaxillary retrognathism. Whereas at II skeletal upset the higher anteriors procline to catch up on jaw retrognathism and lower incisors retrocline to catch up on inframaxillary prognathism. this can be known as presurgical decompensation. Presurgical odontology decompensation is crucial to change the sawbones to create a substantial quantity of surgical correction. Failure to totally take away anterior tooth compensations presurgically can limit the surgical correction, resulting in compromised facial esthetics and occlusion.

For instance, decompensation of skeletal category II upset can usually need the utilization of category of sophistication. III elastics to upright lower incisors and decompensation of skeletal class III upset necessitates the utilization of sophistication II elastics to procline lower incisors and establish adequate reverse overjet. Decompensation accentuates the patient’s deformity however is important for action of traditional occlusal relationships once skeletal bones area unit properly positioned at surgery.

Arch coordination

Arch coordination refers to coordinating the widths of the dental arches so there's a traditional transvers relationship following mesial jaw movements. Coordination involves arch growth, arch contraction, and odontology growth or contraction to coordinate the higher and therefore the lower arches ought to be dispensed before the surgical operation so as to produce correct postoperative occlusal interdigitation. Coordination notably can prohibit or destabilize jaw movements at the time of surgery and compromise postsurgical stability.
