STATEMENT OF THE PROBLEM The use of miniscrews has expedited the true maxillary incisor intrusion and has minimized untoward side effects such as labial tipping. PURPOSE The aim of this study was to assess the stress distribution in the periodontal ligament of maxillary incisors when addressed to different models of intrusion mechanics using miniscrews by employing finite element methods. The...

Introduction: This retrospective study aimed to determine skeletal and dental changes after a growth spurt shortly treatment using facemask in Class III malocclusion with maxillary deficiency. Methods: We retrospectively studied 50 patients (25 per group) who underwent tooth-anchored (T-A, mean age 7.92) miniscrew-anchored (M-A, 9.84) intraoral appliances. In both groups, the applied traction f...

Maxillary deficiency in the transverse dimension is a common problem children. The conventional management of such malocclusion with rapid maxillary expansion. beneficial effects an orthodontic therapy are explained detail literature. But there also negative Thus, improvements methods expansion has led to discovery miniscrew assisted palatal supported by mini implants and thus enable better ske...

background and aims: nowadays miniscrews are widely used as skeletal anchorage in orthodontics. however the success rate of miniscrews is less than that of osseointegrated implants. the aim of this retrospective study was to evaluate factors influencing the success rate of orthodontic miniscrews. materials and methods: data of 244 miniscrews in 122 patients (99 females and 23 males, with a mean...

JCO/FEBRUARY 2003 O movements such as anterior retraction and intrusion of overerupted teeth are difficult to achieve without undesirable reciprocal movements of the anchorage units.1-3 Titanium miniscrews not only provide nondental anchorage, but they are inexpensive, small, simple to place, immediately loadable, and well tolerated by patients.4-9 This article describes a new titanium miniscre...
