background and aims. orientation of the occlusal plane is one of the most important clinical procedures in prosthodontic rehabilitation of edentulous patients. the aim of this study was to define the best posterior reference point of ala-tragus line for orientation of occlusal plane for complete denture fabrication. materials and methods. fifty-three dental students (27 females and 26 males) wi...

OBJECTIVE To compare the mean dental maturity amongst three vertical facial patterns (short, average and long anterior facial heights) and also amongst two sagittal facial patterns (skeletal class I and II) in orthodontic patients. STUDY DESIGN Cross-sectional analytical study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital, Karachi, from August to October 2008. METHODOLOGY ...

PURPOSE This study compared the SCGAs measured in three types of radiographic images (panoramic, CBCT panoramic-section, and CBCT cross-section images) with values measured using the protrusive occlusal record. MATERIALS AND METHODS SCGAs were measured in 20 patients on a semi-adjustable articulator using the protrusive interocclusal record. Panoramic and CBCT images were obtained. SCGAs were...

Two plane geometric graphs are said to be compatible when their union is a plane geometric graph. Let S be a set of n points in the Euclidean plane in general position and let T be any given plane geometric tree whose vertex set is S. The main problem we consider in this work consists of finding a second plane geometric tree T ′ on S, such that T ′ is compatible with T and shares with T a minim...

Introduction: The inclination of the occlusal plane (OP) is related to type of dental occlusion. The aim of this study was to evaluate and compare the inclination of occlusal plane in Class II patients treated with the upper first premolars extraction or non-extraction modalities. Materials & Methods: Totally, forty 16-25-year-old patients (15 males and 25 females) with class II malocclusion, ...
