Evaluation of frictional forces between ceramic brackets and archwires of different alloys compared with metal brackets

Brazilian Oral Research, 2010
The aim of this study was to evaluate, in vitro, frictional forces produced by ceramic brackets and arch wires of different alloys. Frictional tests were performed on three ceramic brackets: monocrystalline (Inspire ICE), polycrystalline (InVu ...

Comparative Evaluation of Treatment Effectiveness in Skeletal Class III Malocclusion: Surgery‐First Approach Using Clear Aligners Versus Fixed Appliances

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This study aimed to assess treatment outcomes, identify predictors of relapse in skeletal Class III patients treated with the surgery‐first approach (SFA), comparing fixed appliances (FA) with invisalign clear aligners (CA). Materials and Methods Forty adult patients treated with bimaxillary surgery and SFA were retrospectively ...

In Vitro Aligners Force Analysis in the Maxillary Arch During En‐Masse Retraction With Different Attachment Positions

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This study aimed to analyse the three‐dimensional forces acting on maxillary teeth with aligners activation of en‐masse retraction based on the different attachment positions in vitro. Methods Three groups were designed for the same 0.25 mm en‐masse retraction forces with three different attachment positions.

Changes in the Pterygopalatine and Midpalatal Sutures After Rapid Palatal Expansion With Tooth‐Bone‐Borne (MARPE) and Tooth‐Borne (Hyrax) Appliances

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective This retrospective cohort study aimed to compare the effects of tooth‐bone‐borne mini‐implant‐assisted rapid palatal expansion (MARPE) and tooth‐borne (Hyrax) rapid palatal expansion (RPE) techniques on the pterygopalatine suture (PPS) and the opening pattern of the midpalatal suture (MPS).

Biomechanical Assessment of Root Torque in Clear Aligners: Impact of Trimline Design, Engagers, and Pressure Points With Palatal Compensation Movement

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Background Root torque control is essential for guiding the proper movement of anterior teeth, primarily to prevent periodontal complications. This movement, in clear aligner therapy (CAT), requires precise force application to minimize unintended displacements.

The Effects of Rapid Periodontal Distraction on Tooth Vitality and Bone Quality/Quantity: A Split‐Mouth Experimental Design

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objectives Periodontal distraction (PD) osteogenesis is a minimally invasive technique capable of rapidly moving uniradicular teeth, thereby shortening orthodontic treatment time. This study aimed to determine whether: (1) PD‐induced tooth movement affects tooth vitality and (2) the regenerated bone meets restorative standards for implant ...
