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.

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.

The study of of dental arches morphology is relevant for the improvement and development of new diagnostic and surgical methods. The aim is to make a comparative evaluation of the dental arches width on the upper jaw in mature aged men with physiological occlusion depending on the craniotype. Material and methods. The morphometric parameters of the maxillary dental arches’ width have been studied. The work was performed on 172 preparations of mature aged male skulls with physiological occlusion of teeth. The cranial index was defined as the ratio of the transverse dimension of neurocranium to its longitudinal dimension. When examining dental arches, the main points were set on the medial and distal corners of the tooth crowns from the vestibular and palatal sides. The width of the maxillary dental arch was measured between canines, premolars and molars. Results. The values of the width indices of both the vestibular and palatal sides of the maxillary dental arches at all levels of measurement prevail in the brachycranial type of the skull. The indicators of the maxillary dental arches width in mesocranes are more then those in dolichocranes only at canines and the first premolars. At the second premolars and molars, the difference in the average statistical parameters of the width of the dental arches was not observed. Conclusions. The width of maxillary dental arches in men of mature age depends on craniotype. The new data obtained as a result of the research, supplement and expand the information on the studied parameters, both in theoretical and clinical aspects.

Abstract Objective: To evaluate the transverse stability of the dental arch in unilateral cleft lip and palate (UCLP) patients after orthodontic treatment with quadhelix and edgewise appliances. Materials and Methods: Twenty repaired complete UCLP patients with posterior crossbites were chosen as the study subjects. All had ceased retention at least 15 months previously. Measurements were carried out directly on the pretreatment, posttreatment, and postretention study models using a three-dimensional dental cast analyzer. The interdental widths were measured for the canines, first premolars, second premolars, first molars, basal bone, and the alveolar arch. Two-way analysis of variance and Fisher's LSD was performed in comparing the difference between intervals. Results: Lower inter-first-premolar width and upper arch widths of each region increased significantly (P < .05) after orthodontic treatment. The expansion was greater in the anterior than the posterior region in the upper arch, and the greatest increase was in the upper first premolar region. The upper arch width decreased after retention, with the decrease of the arch width in the upper canine (1.3 ± 0.8 mm) and first premolar (1.5 ± 0.8 mm) regions being statistically significant. The increased upper arch width in each region and the lower inter-first-premolar width maintained significant expansion after retention. Conclusions: The widths of the dental arch increased significantly after expansion with a quadhelix followed by preadjusted edgewise treatment. Relapse occurred, especially in the upper canine and first premolar region, but most of the treatment effect on the upper arch remained after retention.

Introduction: Tooth crowding can cause complaints if not treated early — this condition resulting in aesthetic disorders, and also masticatory and speech function disruption. The study was aimed to determine the predisposing factors of tooth crowding in the mixed dentition period by the tooth size and dental arch width. Methods: Research type was random cross-sectional. The sample was as much as 29 children with mandibular casting; then the mandibular model cast of these 6 – 9-years old children were divided into two groups according to the crowding condition in the mandibular anterior region, and the measurement was performed afterwards. Space available category was (A/A1), mesiodistal width of mandibular incisor (B/B1), total arch length (C/C1), intercanine width (D/D1), first primary intermolar width (E/E1), second primary intermolar width (F/F1), first permanent intermolar width (G/G1), interalveolar width (H/H1). Result: The results of the t-test showed significant differences (p < 0.05) in the available space for 4 incisors, where the space was larger in the non-crowded group with a difference of 2.22 mm and the mesiodistal sizes of these 4 incisors was larger in the crowded teeth group, with the difference of 1.8 mm. The results of the Pearson correlation coefficient showed a positive relationship to several measurements, namely D to C1, E to D1 and H to B1, C1, D1, F1 and G1, with the t-value > 3 and the r-value was closer to 1, which showed a correlation with strong closeness degree (r > 0.61). Conclusion: Predisposing factors of tooth crowding in the mixed dentition period were the first intercanine width (D), first primary intermolar width (E), and alveolar arch width (H).Keywords: Tooth crowding, arch dimension, mixed dentition period.
