In this paper, we present some novel animation techniques to help users understand complex structures contained in volumetric data from the medical imaging and scientific simulation fields. Because of the occlusion of 3D objects, these complex structures and their 3D relationships usually cannot be revealed using one image. By our animation techniques, the focus regions, the context regions, an...

Correct occlusal relationships are part of the successful prosthetic treatment for edentulous patients. Fabrication of complete dentures comprises of clinical and laboratory procedures that should be executed accurately for achieving success with fabricated dentures. Errors occurring during the clinical and laboratory procedures of a denture may subsequently lead to the occlusal errors in the f...

INTRODUCTION Malocclusions with anterior crossbite are a major esthetic and functional concern for patients. This case report presents a 27-year-old Syrian female who was diagnosed with a class 3 malocclusion, combined with anterior crossbite, deep bite, concave profile, and inadequate maxillary incisor exposure. There was a centric occlusion (CO)/centric relation (CR) discrepancy and the mandi...

The aim of this prospective study was to evaluate the number of contacts in centric occlusion during retention with thermoplastic retainers (Essix retainers) and in the long term. After four premolar extractions and active orthodontic treatment of 15 Class I (10 females, 5 males; mean age 17.20 +/- 1.7 years), thermoplastic retainers were used. Occlusal contacts were determined from occlusal re...

The power stroke of mastication has been traditionally divided into two parts, one which precedes centric occlusion, and the other which follows it-"Phase I" and "Phase II," respectively. Recent studies of primate mastication have called into question the role of Phase II in food processing, as they have found little muscle activity or accompanying bone strain following centric occlusion. That ...

The aim of this study was to determine the correlation between the static and dynamic occlusal factors in patients with anterior disk displacement (DD) and to compare it with occlusion in asymptomatic individuals. The study included a group of 40 patients with DD (median age 35.5) and a control group of 25 students of dental medicine (median age 23.4). In all subjects, the position, i.e. DD was...

The ultimate goal of orthodontic treatment lies in improving both the functional and morphological harmony of occlusal relationship on the part of individuals and maintaining it. Thanks to new development of orthodontic mechanics and progress in techniques in recent years, bodily movement of the teeth has become relatively easy and now we are in a position to obtain the planned occlusal relatio...

Reorganization of an occlusion in a mutilated dentition is the most challenging task which is ever faced by prosthodontists. An occlusal rehabilitation, though it is common, is the most complex treatment procedure which is widely practised in treating severely worn out dentitions, developmental anomalies, acquired defects, ill fitting, long span fixed partial dentures and TMJ disorders. Various...

purpose: to compare repeated intravitreal injections of bevacizumab (ivb) with triamcinolone acetonide (ivt) for treatment of acute branch retinal vein occlusion (brvo). methods: this randomized clinical trial included, 86 eyes with recent onset (less than 12 weeks) brvo. participants were randomly assigned to two treatment groups: the ivb group (43 eyes) consisted of patients who received mont...
