Crowding and protrusion are some of the most common dental cases worldwide. The patient was a 20-year-old female who consulted for severe crowding, protrusion, and deep bite. Clinical examination and cephalometric measurement showed Class I skeletal and proclined incisor. Two step retraction technique was used to correct the condition. Management of tooth tissue discrepancy by the extraction of four premolars is one of the options in the treatment of crowding.

Abstract Background This study aimed to assess the interradicular distance and alveolar bone thickness of Persian adults with different sagittal skeletal patterns for miniscrew insertion using cone-beam computed tomography (CBCT). Methods This cross-sectional study was conducted on maxillary and mandibular CBCT scans of 60 patients (18–35 years) in three groups (n = 20) of class I, II and III sagittal skeletal pattern. Anatomical and skeletal parameters were measured at 2, 4 and 6 mm apical to the cementoenamel junction (CEJ) by one examiner. The intra- and inter-class correlation coefficients were calculated to assess the intra, and interobserver reliability. Data were analyzed by ANOVA and Tukey’s test (alpha = 0.05). Results The intra- and interobserver reliability were > 0.9 for all parameters. The largest inter-radicular distance in the maxilla was between the central incisors (1–1) in classes I and III, and between premolars (4–5) in class II patients. The largest inter-radicular distance in the mandible was between molar teeth (6–7) in all three classes. The buccal cortical plate thickness was maximum at the site of mandibular first and second molars (6–7). The posterior maxilla and mandible showed the maximum thickness of cancellous bone and alveolar process. Wide variations were noted in this respect between class I, II and III patients. Conclusions The area with maximum inter-radicular distance and optimal alveolar bone thickness for miniscrew insertion varies in different individuals, depending on their sagittal skeletal pattern.

Skull Thickness

Objective The objectives of this study were to determine the thickness of skull bones, namely frontal, parietal, and occipital bones in Class I, Class II, and Class III patients. Materials and Methods Three hundred subjects who reported to the Department of Orthodontics requiring orthodontic treatment within the age group 17-35 were selected for the study. They were subdivided into three groups of 100 each according to the skeletal and dental relation. Profile radiographs were taken and the tracings were then scanned, and uploaded to the MATLAB 7.6.0 (R 2008a) software. The total surface areas of the individual bones were estimated by the software, which represented the thickness of each bone. Result Frontal bone was the thickest in Class III malocclusion group and the thinnest in Class II malocclusion group. But the parietal and occipital bone thickness were not significant. During gender differentiation in Class I, malocclusion group frontal bone thickness was more in males than females, In Class II, malocclusion parietal bone thickness was more in males than females. No statistically significant difference exists between genders, in Class III malocclusion group. During inter-comparison, the frontal bone thickness was significant when compared with Class I and Class II malocclusion groups and Class II and Class III malocclusion groups. Conclusion The differences in skull thickness in various malocclusions can be used as an adjunct in diagnosis and treatment planning for orthodontic patients. It was found that the new method (MATLAB 7.6.0 [R 2008a] software) of measuring skull thickness was easier, faster, precise, and accurate.

Aims: To correct the Angle class I malocclusion with crowding via four premolar extractions.Presentation of case:A 19-year-old Malaysian female presented with the bimaxillary protrusion, crowding, high canines, midline deviation and edge-to-edge anterior bite. Upper lateral incisors were palatalized and in crossbite interactions with the opposite teeth.Discussion: Treatment was initiated using fixed orthodontic appliances followed by four 1st premolar extractions in both arches. Case was finished with good inter cuspation of the upper and lower teeth. Molars were finished in a Class I relationship with canine guidance, and ideal overjet and overbite were obtained.Conclusion: Successful finishing of a case with beautiful smile, obtained proper overjet and overbite, corrected cross bite, midline shifting and the improved soft tissue profile.Bangladesh Journal of Medical Science Vol.17(4) 2018 p.683-687
