The purpose of this study is to obtain data of pressure distribution on canine periodontal tissues due to the orthodontic force generated by various types of motion using the Finite Element Method. The development of digital technology creates a numerical analysis for orthodontic treatment that can be done by performing 3-D reconstruction by scanning the maxillary canine teeth with a CT scan so that 255 cross-sectional images is obtained. 3 D model is then processed using the Finite Element Method to obtain the pressure distribution on the periodontal tissues caused by tipping movements, bodily, torque, roots, rotation, and extrusion. The analysis used was the analysis of qualitative and quantitative analysis. The results showed that the maximum pressure that occurs in the periodontal tissues caused by a variety of movements ranging from 3.3 x 10-3MPa to 2.9 x 10-2 MPa. This indicates that the force exerted on each movement produces maximum pressure that exceeds capillary pressure was 2 x 10-3 MPa.

This study was carried out to find the effects of angle of Gable bends and amount of activations of 0.016 x 0.022 inch NiTi and TMA sectional T-loop springs to the force moment and moment delivered. The design of the research is true in-vitro laboratory experimental design, to measure the force, moment. and moments, an axial moment device was designed purposely. The samples were 30 springs comprised of 15 NiTi and 15 TMA with variations of Gable bends 0Ë-0Ë, 10Ë-10Ë, and 20Ë-20Ë Force, moment and moments were measured at 1, 2, and 3 mm amount of activations. Data was tested statistically using the ANAVA with 3x2x3 factorial designs and 5 replications for each all. The results showed that angle of Gable bends, amount of activations and type of wires significantly affect the force and moments delivered, but the angle of Gable bends significantly affect moment. It could be concluded that the greater angle of Gable bends will produce the greater force and moments. The greater amount of activations will produce the greater force and moments.

Model study is one of the standard orthodontic components which is important for diagnosis and treatment plan, but in some patients with the high gag reflex, it will be difficult to get this kind of study models. The existence of a new device which is able to show the condition of patients mouth in three space areas (axial, sagittal, and coronal) is expected to be an alternative when a study model is difficult to get. The purpose of this study is to find out whether or not there are any differences on the size of canines mesiodistal, first and second premolar resulted from CBCT imaging with Moyers analysis on the study models. The method of the research is comparative descriptive. Measurements are made on 10 CBCT imaging results and 10 study models. The mesiodistal size, the result of CBCT imaging is measured by the available computer program and also the mesiodistal size of the study models is measured using a sliding compass, and then the size of canines, first and second premolar teeth resulted from CBCT imaging are compared to the result of Moyers method analysis on the study models. The t-test is used to find out if there is a difference between teeth size value between the CBCT imaging with the study models. The significance is determined based on the p-value < 0,05. The statistical test result shows a significant difference between the size of canines mesiodistal, first and second premolar teeth, the result of CBCT imaging and the Moyers analysis result in the study models in which t count > t table.

The aim of an orthodontic treatment is to achieve aesthetic, dental health and the surrounding tissues, occlusal functional relationship, and stability. The success of an orthodontic treatment is influenced by many factors, such as diagnosis and treatment plan. In order to do a diagnosis and a treatment plan, medical record, clinical examination, radiographic examination, extra oral and intra oral photos, as well as study model analysis are needed. The purpose of this study was to evaluate the differences in dental arch form between level four polynomial and pentamorphic arch form and to determine which one is best suitable for normal occlusion sample. This analytic comparative study was conducted at Faculty of Dentistry Universitas Padjadjaran on 13 models by comparing the dental arch form using the level four polynomial method based on mathematical calculations, the pattern of the pentamorphic arch and mandibular normal occlusion as a control. The results obtained were tested using statistical analysis T student test. The results indicate a significant difference both in the form of level four polynomial method and pentamorphic arch form when compared with mandibular normal occlusion dental arch form. Level four polynomial fits better, compare to pentamorphic arch form.

The purpose of this study was to examine the stability of orthodontic treatment results in dentoskeletal class I malocclusion treated with and without extraction of four premolars and to compare the stability of treatment result between those groups. Occlusal relationship after treatment and six-month post retention were measured on dental cast using The Objective Grading System Index at Orthodontic Specialist Clinic, Faculty of Dentistry Universitas Padjadjaran. The analytic descriptive study was carried out on 30 samples that comprised 14 samples were treated without extraction of four premolars and 16 samples were treated with extraction of four premolars. ABO Measuring Gauge was used to measure seven variables: tooth alignment, the height of the marginal ridges, buccolingual inclination, occlusal relationships, occlusal contacts, overjet, and interproximal tooth contacts. The results were statistically analyzed with the Wilcoxon rank test to test the difference of The Objective Grading System Index between posttreatment and postretension. Mann-Whitney U test was applied to determine the difference between the group with the extraction of four premolars and the group without extraction of four premolars. The level of significance was set at 0.05. The results of this study showed these following variables: tooth alignment, occlusal contacts, and overjet were unstable at the group with the extraction of four premolars, while only tooth alignment was found to be unstable in the group without extraction of the four premolars. Mann-Whitney U test did not show statistically significant difference in stability comparison test between the groups.

Orthodontic treatment has a main purpose to reach balanced functional occlusion and create a harmonic esthetic face. But several studies indicates that orthodontic treatment influence smile esthetics, especially smile arc and buccal corridor. One-third of the treated patients showed a flat smile arc and orthodontic treatment with extraction resulted in excessive buccal corridors. The purpose of this research is to evaluate the difference of the Objective Grading System index, developed by the American Board of Orthodontics (ABO) and smile aesthetics in patients with Class I dentoskeletal malocclusion before and after orthodontic treatment. Twenty dental casts, panoramic radiographs and grouped pre and post-treatment. Dental casts and panoramic radiographs are scored according to the guidelines of the Objective Grading System. Extra-oral photographs were assessed by researcher using modified Goldstein dentofacial analysis. Result of measurements were evaluated with statistical t-test. Results of the research indicates Objective Grading System index and also score of smile esthetics before and after orthodontic treatment shows difference statistically (for Objective Grading System index P = -1121 > 2.09 and for smile esthetics P = 5.15 > 2.09). But extremely weak relationship was found between Objective Grading System index and Aesthetics smiles (231).
