Influence of edentulousness on gonial angle, ramus and condylar height

Journal of Oral Rehabilitation, 2009
Summary  It has been shown that the shape of the mandible correlates with occlusal condition and the function of the masticatory muscles. Edentulous subjects have a wider gonial angle than dentate subjects, and a gender difference has also been shown. However, some studies have reported differing results. Less is known about the effect of dental status

The increased gonial angle in micrognathism

American Journal of Orthodontics, 1953
Abstract 1. 1. The normal mandible has an angle of about 125 degrees between the ramus and the body. 2. 2. Many cases of moderate micrognathism show this angle to be increased as much as 150 degrees. Associated with this increase is a constant esthetic deformity of an excessive superior-inferior length giving the appearance of a “lantern jaw.”

The Morphometric Measurements of the Mandible; Gonial and Incisure Angles

2022
ABSTRACT Background: The mandible, the largest and strongest bone in the face, is the only bone in the skull that does not have a sutural joint. Before starting surgical procedures and clinical approaches, it is necessary to know the anatomy of this region well.

The Influence of the Mandibular Gonial Angle on the Incidence of Mandibular Angle Fracture—A Radiomorphometric Study

Journal of Oral and Maxillofacial Surgery, 2017
The aim of this radiomorphometric study was to analyze the association between the mandibular gonial angle and the risk of mandibular angle fracture.A retrospective analysis of medical records and radiographs of patients treated for mandibular fractures was performed.

Gonial Angle Measured by Orthopantomography as a Predictor of Maximum Occlusal Force

Journal of Prosthodontics, 2017
AbstractPurposeTo establish the accuracy of measuring the gonial angle on an orthopantomogram (GAO), as defined by the anatomic relationship between the inferior and posterior borders of the mandible. Furthermore, to examine the relationship between GAO and maximum occlusal force (MOF) in the premolar and molar regions of healthy young adults.Materials

Impact of the Mandibular Gonial Angle on the Incidence of Angle Fractures of the Mandible

International Journal of Advanced Multidisciplinary Research and Studies
Background: Mandibular angle fractures are influenced by anatomical and dental factors, particularly gonial angle size and third molar impaction. Objective: To assess the association between gonial angle size, third molar impaction, and mandibular angle fractures.

Gonial angle distortion in lateral head films: A methodologic study

American Journal of Orthodontics, 1977
The distortion of the gonial angle in lateral roentgenographic head films was studied in skull material. The left and the right gonial angles were determined craniometrically and roentgenocephalometrically, and the observations were compared. Mean difference of 8.48 degrees and 5.15 degrees between the roentgenocephalometric and the craniometric ...

Estimation of the gonial angle from the orthopantomogram.

Gifu Shika Gakkai zasshi = The Journal of Gifu Dental Society, 1992
We set a new basic plane on an orthopantomogram in order to measure the gonial angle and obtained the following: 1) Usable error difference in ordinary clinical setting ranged from 0.5 degrees-1.0 degree. 2) Because there is no great difference between the levels of the gonial on orthopantomograms, they are effective for investigation of the changes of

Variations of the Gonial Angle in Vertical Surgical Reduction of the Maxillary-Mandibular Complex

Journal of Craniofacial Surgery, 2005
From an esthetic point of view, the mandibular or gonial angle plays an important role in ensuring a harmonious facial profile. The purpose of this study was to analyze the values of the mandibular angle in relation to variations of the vertical and sagittal positions of the jaw.

Gonial angle changes after bilateral unidirectional mandibular distraction in sheep

The European Journal of Orthodontics, 2003
It was the aim of this study to investigate radiologically the distraction site in the gonial angle area after three different protocols of unidirectional mandibular distraction in sheep. Bilateral mandibular distraction was performed in nine sheep, and one other sheep served as a sham-operated control.
