background and aims. bruxism is defined as a habitual nonfunctional forceful contact between occlusal tooth surfaces. in younger children bruxism may be a consequence of the masticatory neuromuscular system immaturity. the aim of this study was to assess the prevalence of bruxism and investigate the relationship between occlusal factors and bruxism among preschool children. materials and method...

INTRODUCTION A reasonable exposure of incisors and gingival tissues is generally considered more attractive than excess or lack of exposure. A reasonable gingival exposure is considered to be around 0 to 2 mm when smiling and 2-4 mm exposure of the maxillary incisor edge when the lips are at rest. OBJECTIVE The aim of this paper is to present the Functional Aesthetic Occlusal Plane (FAOP), wh...

OBJECTIVES To determine if canting of the occlusal plane influences esthetic evaluation of the smile among orthodontists, dentists and laypersons. STUDY DESIGN A frontal photo of a smile with 0 occlusal plane canting in relation to the bipupillary plane was modified using Adobe Photoshop C3 (Adobe Systems Inc, San José, California) to generate two images with occlusal plane inclinations of 2 ...

Basic studies and researches on craniofacial growth show that occlusal plane changes its position in space and time during the whole period of development and growth of the skull until the attainment of the mature dentition stage. The purpose of this retrospective study is to evaluate the inclination of the gnatological occlusal plane related to the axio-orbital plane and their relations with s...

This article reports the orthodontic treatment ofa 25-year-old female patient whose chief complaint was the inclination of the maxillary occlusal plane in front view. The individualized vertical placement of brackets is described. This placement made possible a symmetrical occlusal plane to be achieved in a rather straightforward manner without the need for further technical resources.

Using lateral cephalograms and a jaw movement-recording system, the relationship between the masticatory movement path and dentofacial morphology was investigated in 17 subjects (9 males and 8 females, mean age 23.5 years) without a history of orthodontic treatment. The masticatory movement path was measured at the right and left lower first molar while the subjects chewed gum. The angle betwee...

The posterior reference for the ala tragal line is a cause of confusion, with different authors suggesting different locations as to the superior, middle or inferior part of the tragus. This study was conducted on 200 subjects to evaluate if any correlation exists between the variation of angulation of palatal throat form and the relative parallelism of occlusal plane to ala-tragal line at diff...

PURPOSE This study assessed the accuracy of linear and angular measurements on panoramic radiographs taken at different positions in vitro. MATERIALS AND METHODS Two acrylic models were fabricated from a cast with normal occlusion. Straight and 75° mesially and lingually angulated pins were placed, and standardized panoramic radiographs were taken at standard position, at an 8° downward tilt ...
