“…Our results showed that the patients' age has no influence on the mean bone thickness of the ramus, which confirms the results of Chrcanovic et al [5] and Susilo et al [4] Zhou et al showed that there is no significant difference in the gonion angle between men and women [12], which is consistent with our data. According to that study "the mean mandibular angle was 125.1°in males and 124.1°in females " [12].…”

“…By applying an anatomical grid, comparable thickness measurements could be achieved for an average of 81 points per ramus for which the mean bone thickness could be calculated. This allowed for a more detailed inspection of the ramus anatomy than in previous studies, where the bone thickness of the mandibular ramus was measured at individual points for specific questions, for example to analyse the bone thickness in the course of sagittal split osteotomies by taking one thickness measurement [4] or seven bone thickness measurements at different levels of the ramus [5] or to evaluate the bone thickness for implantation and bone harvesting as performed by Chrcanovic et al [6], where four measurements were taken. Of course, individual mandibles presented a deviation from the calculated mean values, which was found in the standard deviation.…”

“…In orthognathic surgery, the position of the lingula plays an important role in determining the osteotomy line in sagittal and horizontal mandibular osteotomies [3] and the bone thickness seems to be an indicator for the susceptibility to complications during osteotomies [4].…”

“…Various studies have been measuring the bone thickness of the ramus at individual points: Susilo et al [4] measured the bone thickness of the ramus at one point at the level of the lingula as a guide for performing bilateral sagittal split osteotomy in orthognathic surgery and have put their results in relation to the sex and age of the person examined. Also with regard to bilateral osteotomies, Chrcanovic et al [5] performed measurements on CBCT scans.…”

Background: The bone thickness of the human mandibular ramus is an important parameter in mandibular surgeries. The aim of this study was to systematically measure the bicortical bone thickness, the ramus dimensions and the position of the lingula. The measurements were tested on significant correlations to the patients' parameters. Methods: Based on CBCT scans 150 rami were reconstructed as 3D polygon surfaces. An anatomical grid was adapted to the ramus surface to mark the bone thickness measurement points and to achieve comparability between the measurements on different mandibles. The bone thickness, ramus height, ramus width and the gonion angle were measured. A cluster analysis was performed with these parameters to identify clinically relevant groups with anatomical similarities. Results: The median distribution of the bone thickness was calculated and visualized in a pseudo-colour map. The mean ramus height was 44.78 mm, the mean width was 31.31 mm and the mean gonion angle was 124.8°. The average distance from the lingula to the dorsal tangent was 53% of the total width and its distance to the caudal tangent was 65% of the total height. Significant correlations between the bone thickness and the ramus proportions could be identified. Age and sex had no significant influence on the mean bone thickness. The measured rami could be divided into two groups by cluster analysis. Conclusion: The dimensions of the human mandibular ramus can be determined from 3D reconstructed surface models from CBCT scans. Measurements could be made comparable by applying an anatomically oriented grid. A cluster analysis allowed the differentiation of two groups with different bone thickness distributions and geometries, which can be used for the optimization of osteosynthesis systems and their precision of adaptation to different ramus morphologies.

Introduction. Accurate knowledge of mandibular thickness is necessary for performing surgical treatments on the mandible. The Champy procedure has become the predominant approach for treating fractures of the mandible. Placing plates along these lines is believed to offer the best possible fixing and stability. The objective of this study is to analyze and compare the thickness of the mandible in patients, specifically depending on their gender. The purpose is to gain a more comprehensive understanding of the differences in mandibular architecture across various populations in South Sumatra, Indonesia. Methods. This study is a cross-sectional analytical-observational study. The Department of Radiology of Dr. Mohammad Hoesin Central General Hospital, located in Palembang, conducted the study. We included a total of 103 research participants in this study, all of whom met the specified inclusion criteria. Results. There is a notable difference in the thickness of the lower jawbone in the front part (A and B) that runs parallel to Champy's line, depending on the person's gender. Males have a greater morphometric thickness of the mandibular symphysis in comparison to females. The thickness of the mandibular symphysis closely links to gender disparities. Conclusion. The thickness of symphysis A in men was substantially greater than in females, while the thickness of symphysis B in males was also significantly greater than in females, with a P value less than 0.001.
