Abstract

Successful treatment of the adult patient with an open bite dental or skeletal pattern often presents a difficult challenge. The causes of open bite may be multifactorial in nature, there are specific diagnostic criteria that may allow for an orthodontic treatment modality incorporating extraction therapy with retraction of incisors. The intent of this article is to describe and demonstrate the extraction treatment of an open bite caused by a hyperdivergent facial pattern.

Abstract

Obstruction of the upper respiratory tract (OURT) will cause mouth breathing that is known to influence neuromuscular activity. This will lead to malformation of face growth pattern and head posture that can result in dentocraniofacial deformity. This research aimed to identify the differences in soft tissue profile characteristics in OURT patients compared to normal subjects, and to analyze the differences between boys and girls in this respect. An analytic descriptive study with cross sectional design was applied. The sample consists of 96 subjects including 64 OURT patients (32 boys and 32 girls) and 32 normal subjects (11 boys and 21 girls). The results showed that the OURT patients had convex profile and longer distance than the normal subjects between upper or lower lip to esthetic line (p<0.05). Furthermore, normal male subjects had longer distance of upper lip to E-line than females (p=0.039). The same was also shown in OURT patients, i.e. male patients had longer distance of upper and lower lip to E-line compared to females (p<0.05).DOI: 10.14693/jdi.v15i1.83

Abstract

The purpose of this study was to investigate the pattern, mean and differences of measurements between men and women on vertical dentocraniofacial cephalometric values of open bite subjects with anterior tongue thrust. There were 27 subjects between ages of 12-28 years, 6 men and 21 women of which thirteen vertical dentocraniofacial variables were obtained from measurements taken from lateral cephalometrics; ANS-Me, N-Me, S-Go, CC-Go, SN-MP, N-ANS, PP-MP, Y-axis, UPDH, LPDH, ANS-UI, LI-MP and overbite. The means of values of ANS-Me, N-Me S-Go and CC-Go were compared with the norms based on Deuteromalay population and SN-MP, PP-MP, Y-axis UPDH, LPDH, ANS-UI, LI-MP with the norms based on Caucasian population. The obstacle of this study was the unavailable norms of vertical dentocraniofacial cephalometric for Deuteromalay population. Generally the pattern of vertical dentocraniofacial of open bite subjects with anterior tongue thrust shows the long face syndrome.

Abstract

A factor to pay attention to in orthodontic treatment is the inclination of upper and lower incisives. The inclination could be evaluated from interincisal angle and angle of upper incisve (UI) with cranium base (SN). This research is to evaluate those angles after the retraction of upper and lower incisives on malocclusion class I with bimaxillary protrusion. In total, 34 samples were treated using edgewise system. The results show that mean for U1 – L1 is 138.06° ± 1.47°, and for U1 – SN 95.97°±1.27°.

Seorang remaja putri dengan keluhan bahwa gigi geligi depan atas dan bawah tidak dapat mengatup dengan kebiasaan buruk tongue thrust dan profil yang cembung. Kemudian dilakukan perawatan ortodonti dengan menggunakan alat cekat sistim Begg selama 14 bulan dan dibantu dengan memakai tongue crib untuk menghilangkan kebiasaan buruk tongue thrust. Dari hasil perawatan, terlihat bahwa kunci keberhasilan terletak pada penanggulangan dalam menghilangkan kebiasaan buruk.

Abstract

Jasper Jumper is an orthodontic appliance that belongs to fixed functional appliance. This appliance is designed to correct class II malocclusion case, and also further development of Herbst’s. Jasper Jumper can be used to move a tooth, a group of teeth, or the entire denture. In addition, this appliance can produce the same effect as headgear, activator, or any combination of them. Understanding of selected cases, biomechanics and the working mechanism of Jasper Jumper is very helpful for operators working with this appliance in clinics.

Abstract

THe management of orthodontic treatment on cleft lip and cleft palate patients is the challenge for orthodontists. The appropriate age to start the treatment for these patients is remained contradictory amongst experts from various disciplines. In general, orthodontic treatment is provided to prepare for the teeth and jaw for orthognathic surgery to achieve an optimal function and aesthetic. It is often found that patients with cleft lip and cleft palate have underdeveloped of the maxilla in the antero-posterior as well as in transverse direction. However, the orthodontic treatment for these patients will initially focus on the expansion of the maxilla in the transverse direction which will also affect the antero-posterior abnormality. Various expansion devices are available to correct the needs to be considered in treatment the cleft lip and palate patient is the decision whether to open or close the cleft region.

Abstract

Deformasi slot braket dapat mengurangi besar gaya torque  yang akan dihantarkan ke gigi dan jaringan pendukungnya. Beberapa braket stainless steel yang beredar dipasaran belum pernah diteliti kualitasnya dalam perawatan ortodonsi. Tujuan penelitian adalah untuk membandingkan besar gaya torque akibat sudut puntir 30° 45°  kawat stainless steel dan deformasi slot permanen akibat gaya torque tersebut antara kelompok merk braket (3M, Biom, Versadent, Ormco dan Shinye). Penelitian dilakukan pada lima puluh braket stainless steel edgewise dari lima kelompok merk braket (n=10) di lem ke akrilik. Masing-masing braket dilakukan pengukuran tinggi slot dengan mikroskop stereoskopi lalu dipasang ke alat uji torque yang sudah dibuat untuk penelitian ini. Setelah dilakukan uji torque, braket di ukur kembali tinggi slotnya dan dibandingkan dengan pengukuran sebelumnya untuk mengetahui adanya deformasi slot. Hasil analisis statistik menunjukkan perbedaan bermakna besar gaya torque pada sudut puntir 30° dan 45° antara Biom dan Shinye dengan Omrco. Gaya torque paling besar yaitu pada merk braket 3M (30°= 442,12 gmcm dan 45°= 567,99 gmcm), sedangkan yang terkecil adalah Biom (30°= 285,50 gmcm, 45°=361,38 gmcm). Perbedaan deformasi slot braket terjadi hampir pada semua kelompok merk braket. Deformasi slot braket hanya terjadi pada merk braket Biom (2,82 µm) dan Shinye (2,52 µm). Kesimpulan, salah satu faktor yang mempengaruhi besar gaya torque dan terjadinya deformasi slot yaitu komposisi dan proses manufaktur dari braket stainless steel. Proses manufaktur yang tidak sesuai standar dapat menyebabkan kualitas braket yang buruk. Deformasi slot permanen dalam penelitian ini terjadi pada merek braket Biom dan Shinye.ABSTRACT: Slot Deformation of Various Stainless Steel Bracket Due to Torque Expression On The Wire. Bracket slot deformation can reduce the amount of torque that will be transmitted to teeth and supporting tissues. The quality of some stainless steel brackets in the market is still questionable for orthodontic treatments. This research aims to compare the amount of torque expression due to torsion angle of 30° and 45° at the stainless steel wire and bracket slot permanent deformation caused by the torque in each examined bracket brands (3M, Biom, Versadent, Ormco and Shinye). Fifty Stainless Steel Edgewise brackets from five different brands (n = 10) were attached onto an acrylic. Each bracket slot width was measured with a stereoscopic microscope and then mounted onto a torque apparatus that had been prepared for this study. Once the torque test was done, the width of bracket slot was re-measured to determine if there was a difference from initial bracket slot width at 45°. The results of ANOVA showed significant differences in the amount of torque at torsion angle of 30°and 45° between Biom and Shinye with Omrco. The 3M transmitted the highest load (30°= 442,12 gmcm and 45°= 567,99 gmcm), while the lowest was of Biom (300  = 285,50 gmcm and 450 = 361,38 gmcm). Differences in slot bracket deformation were found virtually in all groups of bracket brands. Deformation of bracket slots occurs only in Biom (2.82 µm) and Shinye (2.52 µm). From the observation, it is concluded that one of the major factors that affect torque and deformation of bracket slot is composition and manufacturing process of the stainless steel brackets. Manufacturing process that does not meet the standard can lead to a poor quality bracket. Permanent slot deformation in this study occurrs with Biom and Shinye bracket brands.
