"Tujuan: Mengetahui perbedaan hasil interpretasi superimposisi maksila dan mandibula antara tiga metode superimposisi pada kelompok usia non-growing ≥ 20 tahun. Metode superimposisi maksila yang diteliti adalah pada area best fit, Björk dan Skieller, serta Springate. Sementara metode superimposisi mandibula yang diteliti adalah pada tepi bawah mandibula, Björk dan Skieller, serta Springate. Metode: Tracing dilakukan pada foto sebelum perawatan (T0) dengan membuat garis panduan sella-nasion (SN) dan garis N yang tegak lurus terhadap SN serta struktur anatomis pada regio maksila atau mandibula. Sedangkan pada foto setelah perawatan (T1), tracing dilakukan hanya pada struktur anatomis pada regio maksila dan mandibula saja. Kemudian hasil tracing setelah perawatan (T1) disuperimposisikan di atas hasiltracing sebelum perawatan (T0) berdasarkan berbagai metode superimposisi maksila atau mandibula. Setelah itu garis SN dan N pada tracing sebelum perawatan dipindahkan ke atas hasil tracing setelah perawatan. Terakhir, posisi titik referensi pada maksila (titik ANS, A, dan U1) atau mandibula (titik Pog, B, dan L1) diukur jarak koordinatnya secara vertikal dan horizontal ke garis SN dan N yang berperan sebagai sumbu x dan y. Hasil: Tidak terdapat perbedaan, baik dalam dimensi vertikal maupun horizontal, mengenai hasil interpretasi superimposisi maksila dan mandibula dengan tiga metode superimposisi yang diujikan pada kelompok usia non-growing ≥ 20 tahun. Kesimpulan: Evaluasi perawatan ortodontik pada pasien usia non-growing ≥ 20 tahun menggunakan berbagai metode superimposisi maksila dan mandibula menghasilkan hasil interpretasi yang sama, baik diukur dalam dimensi vertikal maupun horizontal. Sehingga pemilihan metode superimposisi maksila dan mandibula apapun pada pasiennon-growing tidak akan mempengaruhi hasil interpretasi evaluasi perawatan, selama metode superimposisi yang digunakan tetap memperhatikan struktur anatomis yang ada.

Objectives: To compare the interpretation of maxillary and mandibular superimposition between three methods on ≥ 20-year-old non-growing patients. Three maxillary superimposition methods used during the study were best fit, Björk-Skieller, and Springate. Meanwhile for mandibular superimposition, the methods used during the study were inferior border of mandible, Björk-Skieller, and Springate. Method: Tracing was executed on pre-treatment cephalogram (T0) to construct sella-nasion (SN) line and N line which was perpendicular to SN, and also to construct anatomical structures on maxilla or mandible. Tracing at post-treatment cephalogram (T1) was executed on maxillary or mandibular anatomical structures only. Then cephalogram tracing at T1 was superimposed on T0 based on three different superimposition methods on maxilla or mandible. SN line and N line at T0 were then transferred into T1 tracing as a reference line of x and y axis. Hence, the position of maxillary reference points (ANS, A, and U1) or mandibular reference points (Pog, B, and L1) could be accounted vertically and horizontally to the x and y axis. Results: No statistical difference in vertical or horizontal dimention, regarding the interpretation of maxillary and mandibular superimposition between three methods on ≥20-year-old non-growing patients. Conclusion: Post orthodontic treatment evaluation on ≥ 20-year-old non-growing patients using varied maxillary and mandibular superimposition methods may result the same interpretation in vertical or horizontal dimention. Any maxillary or mandibular superimposition methods could be used on non-growing patients and may not affect interpretation on post treatment evaluation, as long as the used methods account any existing anatomical structures."

"To obtain a final occlusion, torque is needed to place the teeth in a precise labiolingual or buccolingual position. Biomechanically principles and arch manipulation is compulsory to produce torque movement. This paper discusses the technique to produce torque and its biomechanical principles. There are two kinds of torque, root torque and crown torque which can be done on anterior as well as posterior teeth by holding the crown in its position while applying a moment of a force on the rest, root torque can be obtained. In root torque, the center of rotation is at the incisal edge or at the bracket with a 12:1 moment to force ratio. Torque can be produced by using retrangular wire or using torquing auxiliaries. Torque movement is frequently needed in orthodontic treatment which needs a through understanding a biomechanical principles."

Background: Patients with fixed orthodontic appliances need to maintain good oral hygiene because the presence of orthodontic appliances such as brackets, arch wire, bands, ligatures and auxaillaries can facilitate plaque and debris accumulation around those sites. The most common way to control dental plaque is by toothbrushing.

Aim: To analyze plaque index differences between the use of orthodontic toothbrush and conventional toothbrush in patients with fixed orthodontic treatment.

Method: In this clinical experimental study, thirty two subjects were randomly divided into two groups which are orthodontic toothbrush group and conventional toothbrush group. Subjects were given the same toothpaste and instructed to brush their teeth twice a day with Bass method for two minutes. Plaque index scores were measured before and after three consecutive weeks of toothbrush usage.

Result: The results of Mann-Whitney test concludes that there is no statistically significant difference between the use of orthodontic toothbrush and conventional toothbrush in patients with fixed orthodontic appliances (p>0,05).

Conclusion: The use of orthodontic toothbrush and conventional toothbrush equally effective to decrease plaque index in patients with fixed orthodontic appliances."
