Jaw Surgery Questions

What is a typical jaw surgery procedure done?

Jaw surgery might involve one jaw or both jaws concurrently. Preoperative diagnosis and planning for patients with jaw asymmetries and deformities may be first done by the pedodontist or orthodontist in coordination with the craniofacial surgeon. All findings are analyzed and pre-surgical model surgery performed to ascertain the feasibility of various treatment options.

Your maxillofacial or craniofacial surgeon pre-contrive all treatment planning with your before confirming for treatment. Orthognathic surgery is often not done until all permanent teeth have erupted unless medical conditions necessitate that the surgery be performed earlier. In adult patients, orthognathic surgery can be combined with soft tissue contouring to improve the aesthetic results.

Usually, pre-surgical orthodontics are necessary to straighten the teeth and align the arches so that a stable occlusion can be obtained post-operatively, while orthodontics following surgery are frequently required to revise minor occlusal discrepancies.

After pre-surgical orthodontics is complete, the actual jaw surgery is arranged and started at our BIDH jaw surgery clinic. Cuts in the mandible and/or maxilla bone is made and re-positioned to the planned alignment.

Post jaw surgery healing, this is followed by orthodontic treatment again to properly align teeth bite to the correct positions.
