Successes 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 کاملAccelerated Tooth Movement with Orthodontic Mini-Screws
This case report outlines the possibility of accelerated tooth movement with the combination of microosteoperforation and mini-screws. A 14-year-old male patient presented Class II malocclusion with maxillary incisor protrusion. Upper first premolars were extracted, and after leveling, accelerated canine distalization started. For pre- and postdistalization times, amount of distalization, perio...
متن کاملThread Pitch Variant in Orthodontic Mini-screws: A 3-D Finite Element Analysis
Orthodontic miniscrews are widely used as temporary anchorage devices to facilitate orthodontic movements. Miniscrew loosening is a common problem, which usually occurs during the first two weeks of treatment. Macrodesign can affect the stability of a miniscrew by changing its diameter, length, thread pitch, thread shape, tapering angle and so on. In this study, a 3-D finite element analysis wa...
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...
متن کاملClinical indices for orthodontic mini-implants.
Orthodontic mini-implants were recently developed and have been widely used in clinics. However, loosening of mini-implants, as well as infection and swelling of mucosal tissue at the placement site, are often observed during orthodontic treatment. Thus, clinical indices are greatly needed for the safe use of orthodontic mini-implants. This article presents information on mini-implants and offe...
