Case report FG. Orthodontic treatment to correct major dental asymmetries.

The correction of major dental asymmetries in adults can be challenging. Many adult patients modify their behavior to compensate for skeletal disharmonies, functional shifts and missing teeth. Some skeletal components, including the temporomandibular joint, also adapt in non-growing patients. Extracting premolars will not always correct a marked asymmetry and orthognathic surgical procedures are frequently inappropriate. In the case of Patient FG, extraction of a mandibular central incisor resulted in improved function and esthetics in a relatively short time with minimal expense and trauma.

[Orthodontic implications in the correction of the transverse dimension in orthognathic surgery].

Transverse skeletal discrepancies are treated in skeletally mature patients with an association of orthodontics and surgical procedures. The orthodontics procedures used depend on the type of surgical maxillary expansion performed. Orthodontics procedures performed before surgery are designed around the analysis of frontal asymmetry. Indications and proper treatment strategy for surgically-assisted maxillary expansion, or for Lefort I osteotomy depend on the magnitude of the transverse deficiency. The orthodontics implications of facial asymmetry remains one of the specific points requiring special care before and after surgery. Long length orthodontics stabilization is required after surgically-assisted rapid maxillary expansion to limit transversal relapse by use of a rigid fixation or another auxiliary stabilizing arch wire.

[The correction of fanned-out incisors--an important orthodontic contribution to aesthetic dentistry].

Account has to be taken of the increased aesthetic awareness of the adult patient by all sub-specialties of dentistry. Here, orthodontics often plays the role of a central link between periodontics and prosthetics. Taking pathological migration of the incisors as an example, the pathogenesis, therapeutic procedures and orthodontic possibilities for the restoration of normal dentofacial aesthetics are demonstrated and discussed.

Prediction of treatment outcome following correction of anterior crossbites in the mixed dentition: orthodontic versus orthopaedic methods.

AIM: To separate subjects with anterior crossbite and mild maxillary deficiency into two groups: those that can be treated successfully with a 2 x 4 appliance and those that should be treated with reverse headgear and maxillary expansion. METHODS: Thirty mixed dentition subjects each with an anterior crossbite, a concave profile, a deficient maxilla, and an ANB angle between -2 and +1 degrees were used. Fifteen subjects (8 boys, 7 girls; Mean age: 9.17 +/- 1.1 years) were successfully treated with a 2 x 4 appliance (orthodontic treatment group) and remainder (5 boys, 10 girls; Mean age: 8.6 +/- 1.5 years) were successfully treated with reverse headgear and maxillary expansion after initial treatment with a 2 x 4 appliance had failed (orthopaedic treatment group). Unstandardised discriminant function coefficients and a constant were calculated for selected pretreatment cephalometric variables. RESULTS: The NSAr angle was significantly smaller (p < 0.01) and both anterior and posterior cranial base lengths were significantly longer in the orthodontic treatment group (p < 0.001) compared with the orthopaedic group. The prediction index developed was: (PI) = -0.2 NSAr + 0.243 S-N + 0.187 S-Ar + 3.366. The critical score was 0. With positive scores a 2 x 4 appliance can be used and with negative scores reverse headgear and expansion are indicated. CONCLUSION: An equation able to predict treatment success with either a 2 x 4 appliance or reverse headgear has been developed.

Orthodontic and orthognathic surgical correction of Class III malocclusion.

This case was presented as part of the student case displays at the 1994 AAO meeting, sponsored by the College of Diplomates of the American Board of Orthodontics. It was selected to be submitted for publication in the American Journal of Orthodontics and Dentofacial Orthopedics by a CDABO committee.
