Mandibular prognathism by bsso study

According to the surgical plan, it was decided to set back the mandible 7. Most instances are considered polygenetic. Postoperative orthodontic treatment lasted for 9 months Figure 2. No correlation was found between the remodeling changes at condylion and gonion and the surgical movement or relapse at B point and pogonion.

The original mandible and maxilla osteotomy procedure still remains almost unchanged, as it is the simplest and still the most effective for dentofacial deformity correction.

They were used to correct dentofacial deformities like a malocclusionand a prognathism. The basic design of the sagittal ramus split surgical procedure evolved very quickly.

Raffaini introduced this technique in after a four-year study done with local anesthesia and assistance from intravenous sedation. This remodeling occurred more in the condylar and gonial areas, while the Mandibular prognathism by bsso study remained relatively stable. The patients stated that there was no loss of the sense of taste.

Descriptive statistics are presented for all variables. Fifty-eight male patients with mandibular prognathism only were treated from to deformities such as discrepancy of jaws, mandibular setback of more than 10 mm, asymmetry, and vertical discrepancy were excluded.

Osteotomy Osteotomy is done with operative micromotor and burs. This article has been cited by other articles in PMC. Case 1 This patient was an year-old man who presented with chief complaints of lack of incisal contact, mandibular protrusion, and mastication problems.

The gonial angle plays an important role in ensuring a harmonious facial profile. The literature was reviewed, and the last modifications of the successful traditional splitting procedure are presented narrowly.

The change in occlusal plane angle at T0 and T1 was not significant in either group. His jaw was so deformed that he was unable to chew.

Mandibular Prognathism by BSSO Study

For many years, and in some countries still, this technique has defined the term oral and maxillofacial surgery. At this time, a vertical cut is made extending inferior to the body of the mandibleto the inferior border of the mandible.

This surgery is usually performed with the use of general anaesthetic and a nasal tube for intubation. The technique was introduced by Schuchart, modified and popularized by Trauner and Obwegeser. The 6-week, 1-year, and long-term postoperative cephalometric mandibular tracings of 12 patients were superimposed using the fixation wires as the stable reference points to demonstrate the specific locations of the intrabony remodeling.

However, without fixation of the proximal and distal segments, this procedure only led to a minor reduction of complications.

Instead, the surgeon is often able to go through the interior of the mouth. Following the osteotomy, a small spatula osteotome is malleted in to the site beginning from the medial slash, down the ramus, over your body upto the vertical lower.

Mandibular Orthognathic Surgeries This procedure is indicated only for mandibular prognathism since it is mainly used to allow mandibular set-back.


The geometric configuration of the mandible makes it difficult to allow back-step of the mandible following BSSO. The Rami will be pushed excessively in a lateral direction and there might.

Orthognathic surgery (/ This procedure is used to correct mandible retrusion and mandibular prognathism (over and under and those who didn't have their third molars extracted during the dentofacial Osteotomy.

The study showed that 73% of patients developed an infection of the hardware inserted into the jaw when having their third.

A retrospective research was conducted on 33 patients (15 females and 18 males), with mean age of 22 years (age range of 19 - 28 years), who were handled for mandibular prognathism by BSSO at the office of dental and maxillofacial surgery, Mar Baselios Tooth School, Kothamangalam.

The timing of removal of mandibular third molars (M3) in Sagittal Split Osteotomy (SSO) has been an issue of contention. The aim of this retrospective study is to identify the incidence of unfavorable fractures during SSO with the presence of M3 and to identify the association between unfavorable.
