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...
helical coil heat exchangers are widely used in industrial applications ranging fromcryogenic processes, air-conditioning, and nuclear reactors to waste heat recovery due totheir compact size and high heat transfer coefficient. in this kind of heat exchangers, flowand heat transfer are complicated. this paper reports a numerical investigation of theinfluence of different parameters such as coil...
Purpose: The aim of this study was evaluation cephalometric changes in treatment skeletal class III malocclusion using miniscrews and intermaxillary closing coil springs. Material methods: Ten patients with Class due to maxillary deficiency were selected, their age range from 12 15 years old erupted all permanent teeth. Miniscrews (Hubit, Hubit co, Korea) inserted (1.6 mm diameter, 10 length) u...
Background: Effects of electromagnetic fields on healing have been investigated for centuries. Substantial data indicates that exposure to electromagnetic field can lead to enhanced healing in both soft and hard tissues. Helmholtz coil is a device that generates pulsed electromagnetic fields. Objective: In this study, a pair of Helmholtz coils for enhancing thehealing process in periodontitis w...
1 The medical staff might not have to be represented here since they only enter what factors that should be monitored and so they can be seen as the same entity as the nurses' station.
