Objectives. This study aimed at finding out whether anterior teeth angulation and inclination have a relationship with the maxillary teeth and dental arch dimensions. Methods. Fifty study models with normal occlusion were selected from the archive of the Department of Orthodontics at Baghdad Dental Faculty. Maxillary dental arch width and length at different points were determined in addition to measuring anterior teeth angulation, inclination, crown thickness, overjet, overbite, and Bolton’s ratios. The unpaired t-test and Pearson’s correlation coefficient test were used for data analysis. Results. No statistical gender differences were reported in all measurements except the dental arch widths and length where males had significantly higher mean values. Only the maxillary incisor’s inclination showed a direct weak significant correlation with the total arch length. Conclusions. The inclination of upper incisors had a minimal effect on increasing dental arch length.

Dental Arch Width

Aim: Objectives: To analyze variations in dental arch width in relation to oral habits.   Materials and Methods : Cross sectional  study was carried out Department of Orthodontics & Dentofacial Orthopedics of Dhaka Dental College & Hospital, Dhaka with a total number of 600 primary school children of 3-6 years ages of Bangladeshi population. Results: This study was a cross sectional study conducted among the 600 children with 3-6 years old prima- ry school children of Bangladeshi population. According to present study, bottle feeding causes significant reduction in maxillary intercanine width and mouth breathers show significant reduction of both arches. Conclusion: It was observed that the children who had used a bottle had a significant reduction in maxillary intercanine width. Breathing through mouth appeared to be associated with a reduction in the size of both arches. This was more significant in the maxillary intercanine , mandibular  intercanine and mandibular molar widths. Therefore to prevent malocclusions, the public should be informed of the harm caused by certain oral habits, the benefits of breast-feeding, and the need to correct bad habits at early life.

Summary Objectives: The diagnostic procedure commences with the initial examination, during which a number of individual findings of the occlusion or malocclusion are clarified [1]. The objective is to describe the morphological and functional characteristics on each patient using specific guidelines, and then to provide a prognosis of the therapy. Upper and lower arch compression in first premolars and molars area was visible before treatment. Methods: A special device (Czech technical university research prototype) was prepared for this purpose. The optical head contains a digital color camera. The front of the optical head consists of a removable prism which is put into the mouth. The findings can display live images from the camera, which can be archived on a PC. The device captured and geometrically calibrated images permitting comparison of several different dental casts. Results: In the first part of this study 792 sets of study plaster casts were screened. Measurements of dental arch width between reference points of canines, first premolars and first molars were made: upper jaw: men: 3-3 – 35.1 mm (SE 0.13); 4-4 – 37.5 mm (SE 0.13); 6-6 – 48.1 mm (SE 0.19); women: 3-3 – 33.4 mm (SE 0.13); 4-4 – 35.6 mm (SE 0.15); 6-6 – 46.7 mm (SE 0.19). The second part concerns the group of 36 patients which is different from the 792 controls. There were studied changes between initial, post-treatment and post-retention alignment of upper and lower dental arch. Conclusions: Geometrically calibrated images help compare several different steps of the treatment and show a significant difference between patients before and after treatment.

Objective: To assess the dental arch forms of Yemeni adult sample. Materials & Method: The Eucledian clustering method of analysis was utilized for the determination of dental arch form. A total of 398 study models were constructed and evaluated to do measurements for both arches using a modified sliding caliper gauge. Six dental cast measurements divided into three sagittal and three transverse measurements were utilized to represent the dental arch width and length measurements. Result: Narrow form is the most prevalent arch form (30.9%) followed by wide form (23.9%), their prominence appear more in females and the least prevalent arch form was the mid form (9.3%), while flat and pointed forms were in between 18.3% and 17.6% respectively. Conclusion: Five arch forms: narrow, wide, mid, pointed and flat were distinguished as unique forms for the dental arches, with the predominance of the narrow arch form were found among Yemeni adults.

Dental Cast

Dental cast analysis is one of the important thing in orthodontic treatments. One of the dental cast analysis which is usually used is Pont analysis, proposed in 1909. Pont did his research to a population in French which is Caucasian and stated that his theory needs to be tested to another ethnics to verify the applicability of Pont analysis to that population. On each race, there are some specific physical characteristics such as the form and width of dentition and dental arch. Minang population are Mongolian who has the different characteristics of dentition and dental arch with the Caucasians.The aim of this study is to identify whether Pont analysis is precise to be used to Minang population. Method : Cross-sectional design was used in this study. This study was done to 65 upper dental casts from Minang student at the Faculty of Dentistry Andalas University who met the inclusion criteria. The difference between the measured and the calculated interpremolar and intermolar arch width was tested with paired T test with the significant value of 0.05 (p=0.05). Result : Mean value of interpremolar width was 37.8838 ± 2.29042 mm and intermolar width was 47.6046±3.18780 mm. The result of statistical analysis showed that there is no significant differences of the measured and the calculated interpremolar and intermolar width of Minang Student at Faculty of Dentistry Andalas University (p>0.05). Conclusion : Pont analysis can be used as one of the dental cast analysis in orthodontic diagnosis and treatment planning to Minang population. It is suggested to do a further research to identify lower dental arch form of the Minang population whose upper dental arch width equals to the predicted arch width according to Pont’s formula.

ABSTRACT Objectives To compare the effects of a hybrid miniscrew-supported expander versus a conventional Hyrax (CH) expander in growing patients. Materials and Methods Forty patients were randomized into two groups: a hybrid Hyrax (HH) expander group using a Hyrax expander with two miniscrews and a CH expander group. The final sample had 18 subjects (8 female, 10 male; initial age of 10.8 years) in the HH group and 14 subjects (6 female, 8 male; initial age of 11.4 years) in the CH group. Cone-beam computed tomography examinations and digital dental models were obtained before expansion and 11 months postexpansion. The primary outcomes included the orthopedic transverse effects of expansion. Intergroup comparison was performed using analysis of covariance (P < .05). Results Significantly greater increases in the nasal cavity width, maxillary width, and buccal alveolar crest width were found for the HH group. No intergroup differences were observed for dental arch width or shape changes. Conclusions The HH group showed greater increases in the nasal cavity width, maxillary width, and buccal alveolar crest width. No differences were observed for intermolar, interpremolar, or intercanine widths; arch length; or arch perimeter. Arch size and shape showed similar changes in both groups.
