Miniscrews as Anchorage Device for Orthodontic Treatment - Randomized Controlled Trials on Anchorage Capacity, Cost Efficiency and Patient Acceptance
In Brief
A clinical study evaluating Topical anesthesia (buccal and palatal), Local anesthesia (buccal and palatal), and 5 other interventions for Orthodontic Anchorage Procedures and Orthodontic Space Closure. Completed, enrolled 80 participants across 1 site.
Detailed Summary
The purpose of this trial is to study and compare two different anchorage techniques. Adolescent patients in need for orthodontic treatment are randomized into Group A and B. Both groups are treated with extractions of the maxillary first premolars and fixed appliance. Anchorage is reinforced by miniscrews in Group A and by molarblock in Group B. The hypotheses are: * that placement of miniscrews does not cause more pain or discomfort than premolar extractions * that molarblock provides increase of anchorage * that miniscrews have a better anchorage capacity than molarblock * that miniscrews are more cost-efficient than conventional anchorage techniques

Interventions
Saliva is removed with a sterile swab followed by application of 5% Lidocaine gel (APL, Sweden) on the gingiva.
Injection of 1,5 ml Xylocaine Dental Adrenaline (Lidocaine hydrochloride 20 mg/ml, adrenaline 12.5 µg/ml, Dentsply Pharmaceutical, Weybridge, Surrey, UK).
Careful extraction of the maxillary first premolars after mobilization.
Saliva is removed with a sterile swab followed by application of 5% Lidocaine gel (APL, Sweden) on the gingiva.
Injection of 0.3 ml Xylocaine Dental Adrenaline (Lidocaine hydrochloride 20 mg/ml, adrenaline 12.5 µg/ml, Dentsply Pharmaceutical, Weybridge, Surrey, UK).
Molarblock is a Stainless steel ligature connecting the maxillary second premolar with the maxillary first and second molar.
The Spider Screw K1 (Health Development Company, Sarcedo, Italy) is a self-drilling and self-tapping screw. Short neck screws (SCR-1508 and SCR-1510) with a diameter of 1.5 mm and length 8 or 10 mm are used.
