Vertical maxillary excess (VME) is frequently referred to as one variation of maxillo-mandibular discrepancy, which is often identified by excessive display of incisors and gingiva during smiling. This anomaly is corrected surgically by superior maxillary impaction, which can be combined by other procedures such as, anterior maxillary segmental osteotomy to relieve the maxillary protrusion, or ...

effects following the use of mandibular advancement in the treatment of obstructive sleep apnea. A study has subsequently been designed to investigate these issues. Design: 100 consecutively treated medically referred patients were reviewed cephalometrically in 6-month intervals (6—30 months) following mandibular advancement therapy. Setting: Orthodontic Private Practice. Patients: 87 males, 13...

OBJECTIVES The purpose of this study was to investigate the effect of a mandibular advancement device on different grades of obstructive sleep apnea using a relatively simple test for the apnea-hypopnea index to determine if a mandibular device will be effective. MATERIAL AND METHODS A total of 68 patients with obstructive sleep apnea syndrome (OSAS) including, 31 with mild, 23 with moderate ...

We have reported a case of triple mental foramina at the right side of the premolar region, which was discovered during reposition and ostheosynthesis of a mandible fracture. A review of the literature, was performed which disclosed no previous clinical cases reported but an incidence of 1.2% of triple foramina after investigating dry skulls or radiographics. The discussion stresses the importa...

Millions of patients require implantable cardiac devices for management of cardiac dysrhythmias. These devices are susceptible to erosion, exposure, or infection and plastic surgeons are consulted when salvage is required. As of yet, an anterior muscle-splitting approach to effectively and safely relocate the device into the subpectoral position has not been described in the plastic surgery lit...

This paper describes and illustrates an innovative versatile skull-holding device for experimental research in cephalometrics. Repositioning of the skulls was evaluated and found to be highly reproducible.

In this article, we report the successful surgical treatment of a patient, 34 years of age, who had a severe gummy smile and a class II malocclusion. The patient had an 11-mm gingival exposure during full smile and a convex profile. A LeFort I osteotomy combined with a horseshoe osteotomy was used for the superior repositioning of the maxilla;then, an intraoral vertical ramus osteotomy (IVRO) a...

This paper introduces a new Finite Element biomechanical model of the human face, which has been developed to be integrated into a simulator for plastic and maxillo-facial surgery. The idea is to be able to predict, from an aesthetic and functional point of view, the deformations of a patient face, resulting from repositioning of the maxillary and mandibular bone structures. This work will comp...

Early diagnosis of impacted mandibular second molar (MM2) is critical since treatment at a later stage can be complicated. It often requires multidisciplinary approach. Surgical uprighting MM2 appears to safe, effective, and reliable alternative conventional orthodontic mechanics with minimal risk morbidity or pulpo-periodontal problems. Timely factors affecting outcomes must assessed for succe...

Techniques for the three-dimensional analysis of facial morphological changes resulting from surgical treatment have recently been proposed. These approaches largely rely on expert manual intervention for placing anatomical landmarks on 3-D facial models which is time consuming and error prone. A new automated approach is presented here which combines a stereo-assisted active shape model for 3-...
