Abstract

Deformasi slot braket Stainless Steel akan mempengaruhi gaya yang diaplikasikan kepada gigi.Tujuan penelitian adalah untuk mengetahui deformasi slot braket dari lima merek braket yaitu 3M, Biom, Versadent, Ormco dan Shinye akibat gaya torque kawat Beta Titanium 0.021x0.025 inci dengan sudut puntir 45° dan besar gaya torque dengan sudut puntir 30° dan 45°. Penelitian juga bertujuan untuk membandingkan deformasi dan besar gaya torque antara kelima merek braket. Penelitian dilakukan pada 50 braket Stainless Steel Edgewise dari lima kelompok merek braket (n=10) dilem ke akrilik. Masing-masing braket dilakukan dua tahapan pengukuran yaitu pengukuran deformasi braket dengan menghitung rerata tinggi slot braket dengan mikroskop stereoskopi sebelum dan sesudah uji torque dan pengukuran besar gaya torque dengan alat uji torque. Hasil analisa statistik menunjukkan terdapat deformasi slot braket pada kelima merek braket dengan deformasi permanen secara klinis pada braket Biom (2,79 µm) dan Shinye (2,29 µm). Besar gaya torque pada kelima braket dari yang paling besar yaitu 3M, Ormco, Versadent, Shinye dan Biom. Perbandingan deformasi slot braket dan besar gaya torque antara kelima braket adalah terdapat perbedaan deformasi slot braket antara kelima merek braket kecuali antara 3M dan Ormco dan Biom dan Shinye dan terdapat perbedaan besar gaya torque antara kelima braket dengan sudut puntir 30° (kecuali 3M dan Ormco) dan 45°. Kesimpulan, Komposisi logam dan proses pembuatan braket merupakan faktor yang mempengaruhi terjadinya deformasi slot braket dan besar gaya torque. Proses pembuatan dengan metode MIM dan komposisi logam AISI 303 dan 17-4PH menurunkan risiko deformasi.ABSTRACT: Slot Deformation in Various Stainless Steel Bracket Products due to The Torqueing Force of Beta Titanium Wire. Stainless Steel bracket slot deformation affects force applied to teeth. The research aims to determine slot deformation of five different bracket brands namely, 3M, Biom, Versadent, Ormco and Shinye due to torque of Beta Titanium wire 0.021 x 0.025 inch with torsional angle of 45° and the amount of torque with torsional angle of 30° and 45°. The research also attempts to compare the deformation and amount of torque among all five bracket brands. Fifity Stainless Steel Edgewise brackets from five bracket group brands (n=10) were attached on acrylic. Bracket slot measurement was carried out in two stages: firstly, deformation measurement by calculating average bracket slot height with stereoscopy microscope before and after application of torque; and secondly, measurement of torque with a torque measurement apparatus. Statistical analysis showed that there are slot deformations on the five bracket brands with clinical permanent deformation on Biom (2,79 µm) and Shinye (2,29 µm). The amount of torque on the five bracket brands from the highest is 3M, Ormco, Versadent, Shinye and Biom. From correlation assessment between bracket slot deformation and amount of torque in the five brands, a difference is found in the deformation in five brands except 3M, Ormco, Biom and Shinye. There is a difference in the amount of torque between the five brands with torsional angle of 30° (except 3M and Ormco) and 45°. It is concluded that metal compositions and manufacturing process are the factors that influence the occurrence of deformation bracket slot and the amount of torque. Manufacturing process using MIM and metal compositions of AISI 303 and 17-4 PH reduce the risk of deformation.

Abstract

Various controversies arise on the appropriate treatment time to treat class IIImalocclusion at the development age. One reason for delay is that the treatment willmake the treatment period longer. Nevertheless, there are other reasons that believethe class III malocclusion must be treated as soon as possible. Accuracy ofexamination is required to obtain the proper diagnosis to determine treatmentoptions. Clinical conditions found in the class III malocclusion can be underdevelopedof maxillae, overdeveloped the mandible, or combination of both. Treatment of classIII malocclusion at the growing age may prevent further severity. A case report of 11yearold boy with class III malocclusion. He is treated with fixed orthodontics toremove obstruction on the maxillae growth. Many treated progression are obtained,although it is still continuing to be continued to maintain the treatmentstabilization. Initial treatment for the class III Malocclusion at the growing age canprevent further severity.

Abstract

Treatment with a fixed orthodontic aims to improve malocclusion and enhance the aesthetic. Traumatic injury to themucosa of the mouth is one of the risks that often occur and can be addressed among others by using mouthwashthat contains hyaluronic acid. This study aimed to determine the effectiveness of 0.1% hyaluronic acid on woundhealing caused by trauma of fixed rthodontic appliance in terms of size wound, redness and pain. Twenty twopatients who had a traumatic injury caused by fixed appliance on buccal or labial mucosa were divided into 2groups: K1, was instructed to rinse 10 ml solution containing 0.1% hyaluronic acid for 2 minutes after brushingteeth, 2 times a day for 4 days; K2, used the K1’s instruction but using a placebo solution. Examination of size areused caliper and reddish wounds are used index measuring wound redness performed before and after treatment,and pain measurement used questionnaires. Based on the statistical analysis of t-test, the percentage of size changes and redness traumatic injury were more significant in K1 than in K2 (p<0.05). While the pain of traumatic changesin K1 than in K2 were not significant (p>0.05). The use of mouthwash containing 0.1% hyaluronic acid wasconcluded proved effective to accelerate the wound healing process, but does not prove effective reducing paincaused by traumatic injury due to fixed orthodontic appliance.
