The aim of dysgnathic surgery is to harmonise the occlusion (bite) and to remodel the face through bone correction. After a detailed analysis of the bite, position of the teeth and facial profile, and after an analysis of the way the mandibular joints are functioning, the patient will receive a personal treatment recommendation.
Generally dysgnathic surgery is only a part of the complex treatment plan, which comprises dental, orthodontic and surgical procedures. The Marigan Clinic provides all specialised disciplines necessary for successful dysgnathic surgery under one roof. In this way, the different treatments are most effective and complement one another.
The most frequently performed dysgnathic surgeries are:
Correction of the lower jaw
The surgical correction of the lower jaw is performed under general anaesthesia. All incisions are made inside the mouth to avoid unsightly scars. A sagittal cleavage (according to Obwegeser – Dal Pont) allows for the separation of the tooth-bearing part from the joint-dependent part of the jaw in order to correct the malposition of the jaw, realigning it with special titanium mini-plates and screws. Three-dimensional changes to the position of the lower jaw can be made. For aesthetic reasons this treatment can also be combined with a chin correction. This type of surgical procedure requires the patient to stay in the clinic for one to three days.
Correction of the upper jaw
The surgical realignment of the upper jaw is also performed under general anaesthesia. All incisions are made inside the mouth to avoid unsightly scars. With the Le Fort I Osteotomy the upper jaw is separated from the facial skull and subsequently realigned with special titanium mini-plates and screws. In this way, any malposition of the upper jaw can be corrected. In special cases, this method allows the surgeon to widen or narrow the upper jaw, depending on the individual needs of the patient. This type of surgical procedure requires the patient to stay in the clinic for one to three days.
Bimaxillary Corrective Osteotomy
Bimaxillary osteotomy includes the correction of both the upper and lower jaw. It is performed with one operation either with or without a chin correction or fracture of the upper jaw. This comprehensive modification is simulated and precisely calculated beforehand on models and x-rays. Patients of the Marigan Clinic will therefore have an exact idea of the changes they can expect prior to actual surgery.
The various stages of the orthodontic-surgical correction involve:
- Orthodontic pre-treatment – decompensation, duration between 6 to 18 months, according to the individual situation of the patient
- Surgery, corrective osteotomy
- Orthodontic fine-tuning
- Stabilisation of the treatment results, retention
