Surface characteristics of retrieved coated and nickel-titanium orthodontic archwires.
OBJECTIVE The purpose of this study was to investigate the effects of oral fluids and archwire-bracket friction on the surface characteristics of NiTi alloy orthodontic archwires with/without aesthetic coating, in vivo for 2-3 months. MATERIALS AND METHODS Different cross-sections of NiTi Archwires (DENTSPLY GAC International) and Titanol Cosmetic Archwires (FORESTADENT® USA Inc.) were examin...

تعداد 20 رأس میش نژاد نائینی 6+-24 ماهه، با میانگین وزن 2/3-+40 کیلوگرم، همراه با 20 رأس بره های آنها در قالب طرح کاملا تصادفی اثر بتائین و مکمل سولفات بر خصوصیات شیر و پشم و عملکرد بره ها بررسی شد. میش ها بطور تصادفی در چهار تیمار قرار گرفتند. تیمارها عبارت بودند از: 1-گروه شاهد 2-بتائین (05/0 درصد ماده خشک) 3-سولفات (24/0 سولفور درصد ماده خشک 4-بتائین هرماه با سولفات. جیره غذائی طبق nrc با مح...
15 صفحه اولSuccesses and failures with orthodontic mini-screws: a retrospective clinical study of 95 mini-screw implantations
The use of mini-screws has increased broadly over the last ten years. Effectively, these implantable devices, greatly reduced in size and easy to set in place and to remove, have provided orthodontists with a low cost means of reinforcing anchorage for a pre-determined period of time. However, their success rate is far from satisfactory compared to the well-established implants used for tooth r...
متن کاملThe effect of insertion angle on orthodontic mini-screw torque
BACKGROUND Primary stability is an important factor for the clinical success of orthodontic mini-screws. The present study made an attempt to evaluate the effect of insertion angle changes on the maximum insertion and removal torque of orthodontic mini-screws. MATERIALS AND METHODS In this experimental study, 72 mini-screws (Dual Top Anchor System, Jeil, 1.6 mm diameter, 8 mm length) were use...
