Lip Morphology Changes Following Orthognathic Surgery for Class III Malocclusion

Abstract

The hypothesis is rejected. The soft tissue morphology of patients with dento-skeletal Class III malocclusion shows a significant improvement after orthognathic surgery.

Lip Morphological Changes and Differences before and after Orthodontic Treatment

“…In addition, these photographs are usually available in the orthodontic office, and they are rated as more attractive than the profile views. However, the present study revealed that there were significant differences of the coordinates of landmarks at rest and on smiling between the Class II and Class III patient group., and they were similar to the result in the previous study 11,[13][14][15] .…”

Short-term periodontal and microbiological changes following orthognathic surgery

“…Orthognathic surgery has become a routine treatment option for the correction of pronounced skeletal deformities, and provides numerous benefits including enhanced masticatory function (Karabouta and Martis, 1985;White and Dolwick, 1992;Zarrinkelk et al, 1996), prevention of periodontal disease (Schultes et al, 1998), therapy of temporo-mandibular disorders (Magnusson et al, 1986;Magnusson et al, 1990;Rodrigues-Garcia et al, 1998), and improvement of phonetics and appearance (Tucker, 1995;Cheng et al, 1998;Altug-Atac et al, 2008;Islam et al, 2010). Despite the benefits that have been associated with the Le Fort I osteotomy of the maxilla and the sagittal split osteotomy of the mandible, it has to be kept in mind that orthognathic surgery, as an elective surgical intervention, is associated with rare but severe complications, such as necrosis of the osteotomised jaw segment, excessive bleeding, and accidental sectioning of, or damage to, the mandibular nerve (Kramer et al, 2004;Teltzrow et al, 2005).…”

Relationships between soft tissues in a posed smile and vertical cephalometric skeletal measurements

“…In orthodontics, considerable attention has been placed on evaluating and correcting not only malocclusions of the dentition and unharmonious skeletal relationships, but also the overlying soft tissues. [4][5][6][7][8] Many studies have been done to look at relationships between hard tissue measurements in the vertical dimension and certain malocclusions, such as the association of posterior maxillary vertical excess and open bites. 9,10 More recently, investigators have started to focus on whether there are any associations between the hard tissue measurements and the soft tissues.…”
