Mandibular Stability and Dentofacial Deformity

NCT01486069 | Completed DMC

• 1 other identifier: FOUSP - PhD Surg - 01
• Study Type: observational
• Target: 30

• Sites: 1

Brief Summary

The present study intends to clarify whether there is positional mandibular stability in patients to be submitted to orthognathic surgery. In case of any instability exists, it is needed to understand if this could be related to a particular type of dentofacial deformity or could have any short-term or long-term influence on outcomes of the orthognathic surgery.

Conditions

Maxillofacial Abnormalities

Keywords

Dentofacial Deformity; Orthognathic Surgery; Mandible; Orthognathic Surgical Procedures

Outcome Measures

Primary Outcomes (1)

• Variability in mandibular position for different dental occlusion registrations

  Centric occlusion, maximum intercuspation and occlusion under general anesthesia

  Perioperative to orthognathic surgery

Study Arms (1)

Dentofacial Deformity

Patients with dentofacial deformities candidate to orthognathic surgery

Eligibility Criteria

• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

Data will be obtained from subjects to be submitted to orthognathic surgery by the Department of Oral \& Maxillofacial Surgery of the Hospital Geral Universitário of the city of Cuiabá - Brazil during the period of March 2012 through March 2013. Considering the local demand, thirty subjects are expected to be included in the research.

You may qualify if:

• Dentofacial Deformity candidate to orthognathic surgery;
• Systemically capable to be submitted to the orthognathic surgery.

You may not qualify if:

• Patient's health condition is not stable enough to guarantee uneventful outcome;
• Required data unable to be achieved;
• Patient not agreeing to participate to the study.
