Introduction. Due to its simplicity, sliding mechanism is very often used in clinical practice for post-extraction space closure, however, the efficiency of this method may be reduced due friction and changes properties materials method. The most commonly methods mechanics are nickel titanium (NiTi) closed coil spring elastic chain. aim study was analyze force degradation application springs ch...

Orthodontic tooth movement occurs due to mechanical stimulation followed by alveolar bone and periodontal ligament remodeling. Bone remodeling is the process of resorption in areas tension formation tension. Various techniques drugs are used speed up orthodontic treatment. This study aims analyze expression BMP2 TRAP6 on after administration Robusta coffee extract. Twenty-four Wistar rats were ...

introduction the aim of this study was to compare the characteristics of deflection load of three kinds of nickel titanium closed coil springs. methods and materials this research was an experimental study. research sample contains three kinds of niti closed coiled springs (heavy, medium, light) from gac, 3m, and rmo factories. 10 springs with 9 mm length for each group (totally 90 springs) wer...

Objective: To evaluate the efficiency of infrared diode laser on pain reduction during canine initial retraction. Methods: Twelve patients in need of canine retraction were selected. The canines were retracted with closed NiTi coil springs activated to 150 g per side. One canine of each patient was randomly selected for laser irradiation immediately after activation and after 3 and 7 days. The ...

Closed coil spring dan elastomeric chain merupakan aksesoris ortodonti yang sering digunakan untuk menghasilkan force dalam menggerakan gigi. Dimana kedua tersebut memiliki sifat degradasi struktur disebabkan oleh beberapa faktor seperti pH, suhu flouride Minuman berkarbonasi minuman mengandung gas karbon dioksida. Karbon dioksida bahan acidifier menjadikan tingkat keasaman sehingga meningkatka...

Background Tipped lower molar over edentulous space is very common in orthodontics practice when adults seek treatment. The segmented arch technique features a predictable force system that provides a controlled release of force that can produce light and continuous tooth movement. Case Description A female adult patient, who lost a permanent lower first molar, needed correction of the positi...

Open coil springs are commonly used in orthodontic practice to create space for a palatally or lingually blocked out tooth. However, very often the clinician encounters a situation where the inter-bracket span is very less and the open coil spring is not long enough to open the required space needed for alignment. In such situations, the clinician needs to remove the arch wire and reinserts a l...
