The aims of this study were to introduce fixed symmetrograph as a device to analyze arch symmetry and to compare the result of arch symmetry measurements using such appliance with commonly used symmetrograph in Faculty of Dentistry Padjadjaran Universitas (Orthocross). Twenty based study models used in this study. The method used in this study was by comparing the result of measurement using orthocross with the result of measurements using fixed symmetrograph. The result of this study revealed there was no significant difference between measurement using orthocross with measurement using fixed symmetrograph (P>0,05). Based on the result of this study, it is recommended to use this fixed symmetrograph, because there were several advantages using this device, for example, symmetrographâs midlines superimpose exactly with study modelâs midlines with the aid of two vertical pins. Even more, the study model can be fixated using two fixators so that the study model and fixed symmetrograph were not moving during measurement.

Publisher : Faculty of Dentistry, Universitas Gadjah Mada

Slot bracket base is one important element to enable sliding movement of the archwire. Bracket reconditioning by means of burning changes the surface roughness of slot bracket base. The heat above 450 °C shows microstructure changes of the slot surface. On this basis, the present study aims to evaluate surface roughness changes of the slot bracket base before and after reconditioning by means of burning. Sixteen premolar brackets standard edgewise were divided into two groups each consisting of eight brackets. These two groups were tested at three different points using Scanning Electron Microscopy (SEM), with 3000 times of magnification. Subsequentl,group A was burned for 5 seconds (approximately 450 °C) and group B was burned for 10 seconds(approximately 643 °C). After treatment,these two groups were tested for the second time using Scanning Electron Microscopy (SEM), with 3000 times magnification and the images were analyzed using a discrete scale quantitative classification. Afterwards, the data were analyzed using ANOVA (p≤0.05) and post hoc analysis. The result showed that surface roughness of the slot bracket base burned for 10 seconds experienced more significant change than that of bracket burned for 5 seconds and that of the control bracket(p≤0.05).Bracket reconditioning using burning either for 5 to 10 seconds change the surface roughness of the slot bracket base.

The development of technology in orthodontic field produces some orthodontic wires that have different deflection abilities. Loading force is the force needed to place an orthodontic wire in bracket slot (activation). Unloading force is the force produced by an orthodontic wire to move tooth (deactivation). Deflection test with three-point bending technique is a technique that is often used to determine the magnitude of the activation and deactivation force of orthodontic wire. Stainless steel (SS), nickel titanium (NiTi), copper nickel titanium (CuNiTi), and beta titanium (TMA), are the types of frequently used wires. This study aimed to compare loading and unloading force on the deflection test of SS, NiTi, CuNiTi, and TMA orthodontic wires sized 0.016 x 0.022 inch on the load-deflection graph. This is a laboratoryexperimental research on a total of 16 pieces of SS, NiTi, CuNiTi, and TMA orthodontic wires sized 0.016 x 0.022 inches. The group was divided based on the type of material. The deflection test was performed using a universal testing machine with a press speed of 5 mm/minute. Loading and unloading forces were recorded on deflections of 0.5; 1; and1.5 mm. Statistical tests of differences among groups were carried out by ANOVA analysis (p-value ≤ 0.05) and post-hoc analysis with T-test. There were significant differences in the loading and unloading forces recorded on deflections of 0.5; 1; and 1.5 mm; except for deflections of 0.5 mm of the SS and nickel-titanium wires. The wire deflection force fromthe lowest to the highest was CuNiTi wire, nickel-titanium wire, TMA wire, and stainless-steel wire.

Background: Evaluation of dental arches is important for both diagnosis and treatment in the fields of orthodontics, prosthodontics, and forensics. The perimeter or circumference affects the gender-specific dimensions of the dental arch. Purpose: To identify the inter-gender difference between maxillary and mandibular intermolar width of the first molars in Indonesia. Methods: This retrospective and comparative analytical study involved a gender-based comparison of maxillary and mandibular intermolar width in the first molars. A purposive sampling technique was employed for data selection. Ninety dental cast models were selected according to the inclusion criteria of non-growing patients and perfect dental conditions, with any damaged dental models being rejected. After selection, the dental cast was marked at the maxillary and mandibular first molar central fossae before being measured three times with a digital vernier caliper. The data obtained was subsequently analyzed by means of a Kolmogorov-Smirnov test, an F-test-Snedecor (with p>0.05) and Independent Sample t-test (with p<0.05). Results: The average maxilla intermolar widths for males and females were 49.36mm and 46.75mm respectively, while the average mandibular intermolar widths for males and females were 43.17mm and 40.5mm. An independent sample t-test showed that the maxilla and mandibular intermolar widths were significantly different for males and females (p=0.000, p<0.05), with male subjects possessing a higher value than female subjects. Conclusion: A significant gender-based difference existed between the maxillary and mandibular intermolar width of patients attending Padjadjaran University Dental Hospital, Bandung, Indonesia.

Background: Impacted maxillary anterior teeth are a problem that has a significant impact on the aesthetics of the smile, dental arches, and occlusion. Teeth that have higher tendencies to get impacted are third molars, maxillary central incisors, maxillary canines, and mandibular premolars. Impacted teeth with severe root dilacerations are usually extracted surgically, then the space will be closed by orthodontic treatment or using a prosthesis. Purpose: This study aims to report the successful orthodontic traction of mesially 90° dilacerated root of impacted maxillary canine. Case: A 15-year-old female patient with the chief complaint of an unerupted left maxillary canine. Intraoral examination showed a class I molar relationship on both sides, a unilateral crossbite on the right side, 8 mm spacing between the maxillary left lateral incisor and the premolar. Also, mild crowding was found on both upper and lower anterior segments. CBCT results showed a left maxillary canine was palatally semi-vertical impacted and had a mesially 90° dilacerated root. A significant stress concentration occurred at the middle and apical of the dilacerated root apex when exposed to orthodontic force; this tends to be a higher potential for resorption. Case Management: The impacted dilacerated canine was successfully moved to the proper position by combining crown exposure surgery, orthodontic traction using continuous light force, and gingivectomy. Furthermore, traction was held using a gold chain combined with an elastic thread tied initially to a modified stainless-steel main archwire; this was followed by piggyback tandem wire and a vertical 3/16” light elastic traction. Conclusion: The patient showed successful traction of the canine in less than six months. In addition, the unilateral posterior crossbite was corrected and functional occlusion was achieved. That canine showed good orthodontic and periodontal stability at one-year follow-up, without any evidence of root resorption.

Air polishing is a technique to clean the surface of tooth enamel and brackets from biofilm, plaque, and stains. This study aimed to analyze the effect of glycine and erythritol powder on air polishing procedures on the surface roughness of the stainless steel brackets slot. Methods: This research is laboratory observational. This study used thirty-two first molar stainless steel brackets edgewise with slots 0.022 inches. The mesial and distal wing sections were cut so the surface roughness tester tip could touch the bracket slot and move without obstacles. The sample was measured for the bracket slot surface roughness, then divided into two groups randomly with 16 brackets each. First group consisted of sixteen brackets treated with air polishing using glycine. Second group consisted of sixteen bracket treated with air polishing using erythritol powder. The brackets slot surface roughness test was measured using surface roughness tester with roughness average (Ra) parameter. Afterward, the data were analyzed using paired sample t-test and independent sample t-test. Results: Changes in surface roughness of the stainless steel brackets slot edgewise before and after the air polishing procedure with glycine and erythritol powder had a significant difference (p glycine = 0,0001; p erythritol = 0,0257). Both groups experienced a decrease in roughness after air polishing 0.115 μm with glycine and 0.092 μm with erythritol.The decrease in surface roughness of the stainless steel brackets slot after the air polishing procedure with glycine powder compared to erythritol powder had no significant difference (p = 0,6085). Conclusions: Air polishing with glycine and erythritol powder causes surface roughness reduction of the stainless steel brackets.Keywords: air polishing; glycine, erythritol; surface roughness of stainless steel bracket slot; surface roughness tester

ABSTRAKPendahuluan: Perawatan ortodonti cekat dengan retraksi gigi anterior rahang atas dapat menyebabkan penurunan tinggi puncak tulang alveolar, karena setiap pergerakan gigi menimbulkan proses resorbsi dan aposisi tulang, bila proses resorbsi lebih besar maka dapat terjadi penurunan puncak tulang alveolar. Besarnya retraksi empat gigi insisif rahang atas dapat dinilai dengan mengukur sudut I-NA. Kaitan antara besarnya retraksi dengan perubahan tinggi puncak tulang alveolar perlu dievaluasi. Metode: Metode penelitian ini adalah penelitian analitik komparatif yang melihat hubungan antara perubahan sudut I-NA dengan tinggi puncak tulang alveolar empat gigi insisif rahang atas sesudah perawatan ortodonti pada kasus retraksi empat gigi anterior. Sampel pada penelitian ini berjumlah 38 sampel dari pasien dengan maloklusi Kelas I dan II. Pengukuran tinggi puncak tulang alveolar dilakukan pada gambaran radiografi panoramik digital dengan menggunakan software Image J dan plugin dari Preus. Perubahan sudut I-NA didapatkan dari analisis sefalometri metode Steiner pada rekam medik. Hasil: Hasil analisis t-test berpasangan memperlihatkan bahwa tinggi puncak tulang alveolar empat gigi insisif rahang atas sesudah perawatan ortodonti pada kasus retraksi empat gigi anterior mengalami perubahan signifikan (p<0,05) berupa penurunan dengan rerata rasio 0,024, dibandingkan dengan tinggi tulang alveolar sebelum perawatan. Hasil analisis korelasi Pearson memperlihatkan bahwa hubungan antara perubahan sudut I-NA dan penurunan puncak tulang alveolar empat gigi insisif rahang atas tidak signifikan (p>0,05). Simpulan: Tinggi puncak tulang alveolar empat gigi insisif rahang atas mengalami penurunan yang signifikan sesudah perawatan ortodonti pada kasus retraksi empat gigi anterior. Perubahan sudut I-NA tidak berhubungan tinggi puncak tulang alveolar empat gigi insisif rahang atas.Kata kunci: alveolar; insisif; software; retraksi; ortodonti; panora ABSTRACTIntroduction: Fixed orthodontic treatment with anterior maxillary teeth retraction can cause a decrease in the height of the alveolar bone crest. Bone resorption and apposition are caused by tooth movement; if the resorption process is more significant than apposition, there can be a decrease in the height of the alveolar bone crest. The magnitude of the retraction of the four maxillary incisors can be assessed by measuring the I-NA angle. The relationship between the magnitude of retraction and the alveolar crest height changes needs to be evaluated. Methods: This research method is a comparative analysis to study the relationship between the changes in I-NA angle and the height of the alveolar bone crest of the four maxillary incisors after orthodontic treatment with four anterior teeth retraction. The 38 samples from patients with Class I and II malocclusion were obtained. The height of the alveolar bone was measured on a digital panoramic radiograph using Image J software and a plugin from Preus, and the changes in the I-NA angle were measured with the Steiner cephalometric analysis. Results: The results of paired t-test analysis showed that the height of the alveolar bone crest of the four maxillary incisors after orthodontic treatment with four maxillary incisors retraction experienced a significant change (p<0.05) in the form of a decrease with a mean ratio of 0.024, compared to the alveolar bone height before treatment. The results of Pearson correlation analysis showed that the relationship between changes in the I-NA angle and the decrease in the alveolar crest of the four maxillary incisors was not significant (p>0.05). Conclusion: The height of the alveolar bone crest of the four maxillary incisors decreased significantly after orthodontic treatment in the retraction of the four anterior teeth. Changes in the I-NA angle were not related to the height of the alveolar crest of the four maxillary incisors.Keywords : alveolar; incisor; software; retraction; orthodontic ; panoramic
