Intrusion of overerupted maxillary molars with miniscrew implant anchorage: a radiographic evaluation.

The aim of this retrospective study was to quantitatively evaluate the treatment effects of intrusion of overerupted maxillary molars using miniscrew implant anchorage and to investigate the apical root resorption after molar intrusion. The subjects included 30 patients whose average ages were 35.5±9.

Measurement of cortical bone thickness in adults by cone-beam computerized tomography for orthodontic miniscrews placement.

The purpose of this study was to investigate the cortical bone thickness of the inter-dental area of both jaws for orthodontic miniscrew placement. The cone-beam computerized tomography images of 32 non-orthodontic adults with normal occlusion were taken to measure the cortical bone thickness in both jaws. One-way analysis of variance (ANOVA) was used to analyze the differences in cortical bone thickness.

[Evaluation of palatal bone thickness in adults with normal occlusion for orthodontic miniscrews placement].

Objective: To investigate the palatal bone thickness in adult with normal occlusion.

Methods: The cone beam computerized tomography records of 32 adults with normal occlusion (16 males and 16 females), mean age (30.1 ± 6.

[Implant restoration for patients with congenital missing teeth].

Objective: To evaluate the treatment plan, clinical outcome and related problems in patients with congenital missing teeth.

Methods: From November 2000 to February 2009, thirty seven patients with congenital missing teeth underwent thorough diagnostic workup, treatment planning and an interdisciplinary approach to ensure optimal treatment in Department of Implant Dentistry, Peking University, School and Hospital of Stomatology. A standard follow-up protocol was conducted for all the patients.

[Clinical application of miniscrew implant for maximum anchorage cases].

Objective: The purpose of this study was to evaluate the efficiency of the self-drilling miniscrew implant for maximum anchorage cases.

Methods: The study comprised 5 patients whose ages ranged from 14 to 31 years. All patients presented with.
