Dans ce travail nous ttudions l’existence et la convergence de variites inertielles pour la discretisation en temps d’equations d’evolution. Nous montrons que pour des pas de temps petits, et sous une condition qui assure l’existence de varietts inertielles exactes (condition d&cart spectral), le probleme disc&i& posdde une varitti: inertielle de mCme dimension. Nous montrons la convergence de ...

We report a case series of ten patients who presented with anterior open bite. The initial evaluation included clinical pictures, lateral cephalometric radiographs and dental casts. They were assessed according to the severity of the open bite and the cause (skeletal or dental). They all underwent orthodontic treatment as an initial step. Five patients with dental open bite underwent molar intr...

This case report describes the successful treatment of a 26-year-old Caucasian male with skeletal and dental Class III malocclusion associated with mild maxillary and mandibular crowding. The patient had anteroposterior and transverse discrepancies with a reverse overjet and bilateral posterior crossbites. The nonextraction treatment plan included aligning and leveling of the teeth in both arch...

For the cleft patient presenting in adolescence with a jaw discrepancy and malocclusion, misinformation and limited available surgical and dental expertise often prevents a favorable facial reconstruction and dental rehabilitation. A major advantage of the modified Le Fort I osteotomy is its ability to simultaneously close cleft dental gap(s), resolve oronasal fistulas, manage skeletal defects,...

Excessive gingival exposure at the maxillary anterior region during not only smiling (a gummy face) but also at rest creates both functional and aesthetic problems for patients. We herein introduce a unique treatment procedure for mandibular retrognathia with a gummy face. This procedure combines conventional Le Fort I osteotomy and following corticotomy at the anterior region of the maxilla. S...

This is the first review on orthognathic surgery in Malaysia. The records of a total of 84 patients seen between 1977 and 1999 in the Department of Oral and Maxillofacial Surgery of the Faculty of Dentistry, University of Malaya were analysed. Skeletal III deformity formed 85% of the sample with a female dominance of 2 to 1. The patients' age ranged from 17 to 36 years, with a mean of 25.3 year...

For a permutation π in the symmetric group Sn let the total degree be its valency in the Hasse diagram of the strong Bruhat order on Sn, and let the down degree be the number of permutations which are covered by π in the strong Bruhat order. The maxima of the total degree and the down degree and their values at a random permutation are computed. Proofs involve variants of a classical theorem of...

Pycnodysostosis is a rare autosomal recessive skeletal disorder involving a constellation of craniofacial manifestations including midface retrusion. We report the case of a 13-year-old girl with pycnodysostosis who presented with exorbitism, midface retrusion, malocclusion, and obstructive sleep apnea. Here, we describe the successful use of subcranial Le Fort III advancement using distraction...
