Volumetric Analysis of Root Resorption With Mini-Screw Implant Anchorage-assisted Retraction of Maxillary Incisors
This trial is active, not recruiting.
|Start date||August 2014|
|End date||December 2015|
|Trial size||60 participants|
|Trial identifier||NCT02221206, NSF81371167|
The intended study is designed as a prospective randomized controlled trial (RCT), comparing and contrasting the effect of mini-screw implant anchorage-assisted versus regular maximum anchorage by retracting the maxillary incisors.
|Observational model||case control|
time frame: 10 months after implant insertion
Male or female participants from 18 years up to 25 years old.
Inclusion Criteria: - Orthodontic indication for skeletal anchorage - Adequate bone quantity for a palatal implant in the CBCT - Good oral hygiene and normal wound healing capacity Exclusion Criteria: - Patients with cheilognathopalatoschisis and other system syndromes associated with craniofacial anomalies - Patients with immunodeficiency, diseases requiring a prolonged steroid usage, previous radiation therapy or chemotherapy - Patients with metabolic bone diseases or uncontrolled endocrine disorders - Alcohol or drug abuse - Pregnancy
|Official title||Clinical Observation for the Root Resorption With Mini-Screw Implant Anchorage-assisted Retraction of Maxillary Incisors|
|Principal investigator||Mengjie Wu, MD, DDS|
|Description||The objective of the clinical study proposal will be to investigate the performance of early root resorption in order to find out if the magnitude and direction of retraction is appropriate for the retraction of maxillary incisors following the mini-screw anchorage. Therefore, the study will compare and contrast the efficacy and results of the volumetric measurement by CBCT. Patients Males or females whose diagnoses require implant anchorage treatment will be included in the study. Inclusion criteria for the study are as followings: Orthodontic indication for skeletal anchorage Adequate bone quantity for a palatal implant in the CBCT Good oral hygiene and normal wound healing capacity|
