Factors Associated with the Success of Orthodontic Miniscrews

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 mea...

Factors associated with the success rate of orthodontic miniscrews placed in the upper and lower posterior buccal region.

OBJECTIVE To determine the success rate and the factors related to the success rate of orthodontic miniscrew implants (OMI) placed at the attached gingiva of the posterior buccal region. MATERIALS AND METHODS Four hundred eighty OMI placed in 209 orthodontic patients were examined retroactively. The sample was divided into young patients (range 10-18 years, N = 108) and adult patients (range ...

Patients’ satisfaction with orthodontic treatment and associated factors

Effects of microgrooves on the success rate and soft tissue adaptation of orthodontic miniscrews.

OBJECTIVE To evaluate the effect of microgrooves on orthodontic miniscrews in terms of success rate and soft tissue adaptation in animal experiments. MATERIALS AND METHODS The sample consisted of a non-microgroove (NMG) group and a microgroove group (MG; 50 microm pitch and 10 microm depth microgroove on the upper surface of the miniscrew). Miniscrews of 1.6 mm diameter and 6.0 mm length were...

Prognostic factors associated with the success rates of posterior orthodontic miniscrew implants: A subgroup meta-analysis

OBJECTIVE To systematically review previous studies and to assess, via a subgroup meta-analysis, the combined odds ratio (OR) of prognostic factors affecting the success of miniscrew implants (MIs) inserted into the buccal posterior region. METHODS Three electronic searches that were limited to articles on clinical human studies using MIs that were published in English prior to March 2015 wer...

Risks and complications of orthodontic miniscrews.

The risks associated with miniscrew placement should be clearly understood by both the clinician and the patient. Complications can arise during miniscrew placement and after orthodontic loading that affect stability and patient safety. A thorough understanding of proper placement technique, bone density and landscape, peri-implant soft-tissue, regional anatomic structures, and patient home car...
