The purpose of this study was to investigate the position of the mandibular foramen from deciduous (Hellman's stage IIA) to early permanent dentition (Hellman's stage IVA). Panoramic radiographs of 311 Taiwanese children were used. The results revealed that the distances between the mandibular foramen and ramus anterior plane were greater than those between the mandibular foramen and ramus post...

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...

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 ...

INTRODUCTION In this cephalometric investigation, we analyzed the treatment and posttreatment effects of an orthopedic protocol for Class III malocclusion consisting of a facial mask combined with a removable bite-block appliance. METHODS The treated sample consisted of 22 Class III patients treated with the facial mask and bite-block protocol before the pubertal growth spurt (mean age, 8.9 +...

Aim: The purpose of this research was to three-dimensionally evaluate the mandibular angle morphology in open bite subjects with different sagittal skeletal relationships. Material and Methods: Cone beam computed tomography (CBCT) images 26 (12 men 14 women) anterior were evaluated. sample included 3 groups categorized by their relationship (based on ANB anteroposterior dysplasia indicator (APD...

Purpose: This study aimed to measure the amount of change in mandibular angle, intergonial width, and ramus angulation due intersegmental interference changes condyle position after bilateral sagittal split osteotomy (BSSRO) patients with prognathism evaluate correlation between them. Materials Methods: A total 32 who underwent setback using BSSRO mandible manage skeletal during years 2018 2020...

Digitalization and additive manufacturing offer new possibilities in the of individualized medical dental products. In paper we present results first 30 consecutive growing patients (15 males 15 females), with a mean age 13.69 years (SD = 1.26), who were treated for mandibular retrognathia (skeletal Class II malocclusion), using fixed sagittal guidance (FSG) appliance, individually manufactured...
