BACKGROUND This study aimed to determine if mandibular parameters (gonial angle, bigonial width and ramus height) measured from panoramic radiographs, can be used to determine a correlation with an individual's age and gender in dentate subjects in Far North Queensland. MATERIAL AND METHODS The study utilised 2699 randomly selected panoramic radiographs of patients between the ages of 19-69 y...

PURPOSE The objective of this study was to assess gonial angle under the angle classification by comparing panoramic radiograph and lateral cephalometric radiograph. MATERIALS AND METHODS 49 patients (25 males, 24 females) with an age range of 12-29 years participated in the present study. Subjects were retrospectively selected among those categorised as skeletal and dental Class I, II, and I...

Result: All patients had symmetric, natural osteotomy lines, and satisfactory facial ratios in a single-stage operation. The average relative error of VSP and post-op result on the entire skull was 0.41 ± 0.13 mm. The average new left gonial error(Go’-L Error) was 0.43 ± 0.77mm. The average new right gonial error(Go’-R Error) was 0.45 ± 0.69mm. The Average pognion error(Pg error) was 0.79 ± 1.2...

BACKGROUND Restoring the vertical dimension is a critical procedure in prosthetic dentistry. Anterior facial height has a significant impact on the length of the ramus. Patients with deep bite will exhibit a shorter lower facial height; hence, restoring the vertical dimension esthetically without altering the facial form is highly challenging. AIM To evaluate the relationship of gonial angle,...

I T has been known since the early work of PLOUGH (1917, 1921) that alterations in temperature can increase recombination frequencies in females of Drosophila melanogaster. Two distinct, yet related, problems have arisen from such studies. First, does the additional frequency of crossing over represent gonial or meiotic events, or both? Second, does temperature act at the time of crossing over ...

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. In the nine experimental sheep, three different distraction protocols were used. In three sh...

BACKGROUND Mandibular cortical indices, like the mandibular cortical index (MCI), panoramic mandibular index (PMI), mental index (MI), antegonial index (AI) and gonial index (GI) have been developed to assess and quantify the quality of mandibular bone mass. Aim and Objectives : The aim of this pilot study was to measure the radiomorphometric indices in a digital panoramic radiograph and find t...

The purpose of this study was to evaluate the craniofacial and occlusal characteristics of the inhabitants in China. The material consisted of cephalograms, pantomograms, dental casts and anthropological measurements taken from 517 inhabitants: 416 Han Chinese in Beijing, Shanghai, Guangzhou and Changchun and 101 Mongolians in Hohhot. The data were compared among the above five regions and also...
