RANK/RANKL/OPG gene polymorphisms and loss of orthodontic mini-implants.

Objective: To investigate the association of genetic polymorphisms (tagSNPs type) of RANK/RANKL/OPG genes with the loss of orthodontic mini-implants (MIs).

Setting And Sample Population: One hundred and thirty-five patients of both sexes, with mean age of 48.7 ± 10 (20-76 years), were studied.

Assessing the effects of hydrogen peroxide bleaching agent on the shear bond strength of orthodontic brackets.

Background: Tooth bleaching is, today, one of the most widespread cosmetic treatments in dental practice,  so it is important to determine whether it can interfere with orthodontic bonding or not.

Aim: The aim of this study was to assess the in vitro effects of 35% hydrogen peroxide bleaching agent on the shear bond strength of orthodontic brackets.

Materials And Methods: Forty-five upper bicuspids were divided into three groups (n = 15).

Changes in Lip Profile of Edentulous Patients After Placement of Maxillary Implant-Supported Fixed Prosthesis: Is a Wax Try-in a Reliable Diagnostic Tool?

Purpose: A diagnostic wax try-in has been recommended to correctly design the future prosthesis for edentulous maxillae and to predict its effect on the supporting oral tissues. The objectives of this study were to analyze (1) the reliability of this diagnostic tool in planning fixed implant-supported prostheses and (2) the amount of prosthetic compensation required.

Materials And Methods: Nine female patients participated in this prospective study (mean age, 53.

Effects of pilot holes on longitudinal miniscrew stability and bony adaptation.

Introduction: The purposes of this study were to longitudinally evaluate the effects of pilot holes on miniscrew implant (MSI) stability and to determine whether the effects can be attributed to the quality or the quantity of bone surrounding the MSI.

Methods: Using a randomized split-mouth design in 6 skeletally mature female foxhound-mix dogs, 17 MSIs (1.6 mm outer diameter) placed with pilot holes (1.

Local application of zoledronate enhances miniscrew implant stability in dogs.

Introduction: The primary purposes of this study were to evaluate how locally delivered zoledronate affects the longitudinal stability of miniscrew implants (MSIs) and the healing of bone around MSIs.

Methods: Using a randomized split-mouth design, 60 unloaded MSIs (5 × 1.6 mm) were placed in skeletally mature male foxhound-mixed breed dogs.

Stability changes of miniscrew implants over time.

Purpose: To quantify in vivo changes in miniscrew implant (MSI) stability over time using resonance frequency analysis, and to determine if pilot holes and placement sites affect changes in MSI stability.

Materials And Methods: Twenty-two self-tapping MSIs (1.6 mm wide and 9 mm long) were placed in the maxillae of 2 adult beagle dogs (20 months old).
