“…Using a similar method, Szymańska and Sidoro wicz [16,21] evaluated the relationship between bite force and facial skeleton morphology. They found a significant relationship between bite force and the posterior height of the maxilla alveolar process.…”

“…Maximum bite force is one of the most important indicators of the functional situation of the masticatory system and its value is used to diagnose disorders of the musculoskeletal system of facial skeleton [20]. Maximum bite force is affected by skeletal craniofacial morphology, depending on the posterior/ anterior facial height ratio, vertical facial relationships, mandibular inclination and gonial angle [16,21,22]. Malocclusions are commonly associated with reduced maximum bite force.…”

“…Facial skeletal biotype is related to the growth of the mandible. Researches 22 have shown relationships between facial skeletal characteristics and multiple factors like occlusal forces, morphology of masticatory muscles and shape of mandible. Due to short mandibular ramus in high-angle patients, the maxillary plane will rotate and a compensatory dentoalveolar mechanism will be induced 23 .…”

Background: The correlation between extension of the maxillary sinus floor and vertical facial skeletal patterns is important for designing orthodontic treatment plans. We correlated the extension of the maxillary sinus (MS) floor with different facial skeletal malocclusion in adolescent patients aged 10-19 years old using a cone-beam computed tomography. Methods: The relationship between the root tips of upper posterior teeth and the sinus floor was typed and scored (0-4) using cone-beam computed tomography (CBCT) images. Scores of each tooth and each patient were formulated.The cephalometric radiographs were analyzed with Dolphin software to diagnose patients' facial skeletal types into three groups according to Frankfort mandibular plane angle (FMA) as high-angle, average-angle and low-angle groups and ANB angle as Class I, Class II and Class III groups separately. The influences caused by age, sex, and facial skeletal malocclusion on the tooth and patient score were analyzed. Results: In high-angle group, the first molar (FM) score was significantly higher than that in the average-angle and low-angle groups (P = 0.018). Age has a positive effect on the patient score and some of the tooth scores, such as the second premolar (SPM) score, FM score, and the second molar (SM) score, and in the skeletal facial malocclusion. With increasing age, SM score increased along with the Frankfort mandibular plane angle (FMA). No significant difference was found in the distribution of patient and tooth scores by ANB angles. Conclusion: The relationship between the maxillary posterior roots and the sinus floor is correlated with facial skeletal malocclusion in 10- to 19-year-old adolescents. More first molar root tips were inside the sinus in the high-angle group compared with the average-angle and low-angle skeletal patterns. With advancing age, more second molar root tips were more close to contact the sinus floor in the high-angle group. Consideration of the root-sinus position in the posterior maxillary area before establishing an orthodontic treatment plan is recommended.

Background The aim of this study is to evaluate through computed tomography differences in cortical plate thickness of condyle in patients with different facial vertical skeletal pattern.Methods The final sample of this retrospective study included CBCT exams of 60 adult subjects (mean age 33.2 ± 5.6), selected from the digital archive of a private practice. The subjects were assigned to 3 different groups according to the values of the Frankfurt-mandibular plane angle: hyper- normo- and hypodivergent group. The volume rendering of the mandible was obtained and three condylar points were marked on it: median pole, lateral pole and the most cranial point. For each considered reference point the minimum distance between external and internal cortical surface was measured, obtaining three different outcomes: median pole, lateral pole and cranial point cortical bone thickness. The measurement was executed by means of Mimics software by the same expert operator in specific scan views.Results The cortical bone thickness of hyperdivergent patients was found to be statistically thicker than normodivergent patients and hypodivergent patients. Cortical bone thickness of normodivergent patients was found thicker than hypodivergent patients. All the differences were statistically significant (p<0.05). The Person correlation coefficient showed a statistically significant correlation (p<.001) between the Frankfurt-mandibular plane angle and the evaluated cortical bone thickness outcomes.Conclusion Facial biotype characteristics that define vertical facial skeletal pattern affect the cortical bone thickness of mandibular condyle.
