Effect of screw diameter on orthodontic skeletal anchorage.
INTRODUCTION Many case reports have documented the successful use of titanium miniscrews for orthodontic anchorage. However, the literature lacks a well-controlled study examining the effect of miniscrew diameter on anchorage force resistance. The purpose of this in-vitro study was to compare the force resistance of larger-diameter monocortical miniscrews to smaller-diameter monocortical minisc...
متن کاملSpider Screw: skeletal anchorage system.
The stability of the anchorage unit plays a very important role in orthodontic control. Controlled orthodontic movements such as retraction and/or protraction of teeth and intrusion of overerupted teeth are very difficult to achieve without patient cooperation and without causing undesirable reciprocal movement in the anchorage unit. The article describes characteristics, surgical procedure, an...
متن کاملTransalveolar screw: a new concept for orthodontic anchorage.
The purpose of this article is to describe the use of a new trans-alveolar screw (TAS) as a temporary orthodontic anchorage device for the posterior maxilla, to intrude overerupted maxillary molars. To date, five consecutive patients have been treated with these newly designed screws. Intrusions achieved ranged from 2.1 and 6mm (mean 4.7 mm). The TAS is cheap, easy to place and remove by the or...
متن کاملFiber- Reinforced Composite for Orthodontic Anchorage Technique
Introduction: In orthodontic treatment, adequate anchorage is necessary to move the intended teeth. In some cases, just anterior teeth are malaligned, while posterior occlusion is acceptable. Therefore, the posterior teeth could be integrated by fiber-reinforced composite (FRC) to provide a rigid anchorage. This method proved advantageous since brackets are bonded just to anter...
متن کاملNoncompliance open-bite treatment with zygomatic anchorage.
OBJECTIVE To evaluate the dentoalveolar and skeletal effects of the new-generation open-bite appliance. SUBJECTS AND METHODS The study group was composed of 11 subjects with a mean age of 19.5 years who underwent intrusion of the posterior dentoalveolar segment using an open-bite appliance supported by bilateral zygomatic implants. The study was carried out on lateral cephalograms of the subj...
