What competencies does an orthodontic postgraduate need?

Background: Competency frameworks are used to guide professional education and assessment. An orthodontic graduate needs various competencies. This study aimed to determine competencies and create a basic competency framework for orthodontic graduates.

The Effect of Bonding Surface Design on Shear Bond Strength of 3D-Printed Orthodontic Attachments.

Introduction: This study compared the shear bond strength (SBS) of four innovative designs of the bonding surface of 3D-printed orthodontic attachments with conventional mesh design.

Methods: In this in vitro study, the bonding surface design in different groups was as follows: Group 1, flat surface without any feature as a negative control; Group 2, concentric circles with no cuts; Group 3, concentric circles with 16 radial cuts; Group 4, concentric circles with 32 radial cuts; Group 5, small cones with a flat end and rounded edges; Group 6, mesh-based commercially available metal brackets of the maxillary central incisor (standard edgewise, Dentaurum®) as a positive control ( = 20). In Groups 1-5, attachments were designed with SolidWorks® Software and printed with a 2K DLP-LCD printer with hard tough resin (eSun®).

Effect of hydrochloric acid, sodium hypochlorite, and autoclave sterilization on the force characteristics of orthodontic NiTi-closed coils.

Background: This study presented a cleaning method for orthodontic NiTi-closed coils and evaluated its effect on the force characteristics of these coils.

Materials And Methods: In this study, 160 orthodontic NiTi-closed coils, 160 orthodontic NiTi-closed coils (9 mm) from two brands G and H and DB, randomly assigned into four groups. Group 1: Three times of immersion in the 10% hydrochloric acid (HCI) solution for 1 min followed by the immersion in 5.

Bonding Surface Designs in Fixed Orthodontic Attachments.

Fixed orthodontic attachments/appliances work as a medium to transfer the force applied to the teeth. In bonded types, several factors affect the attachment bond strength and their clinical success. The primary approach for increasing the bond strength focused on altering the time and concentration of acid etching; however, the results showed that these changes might increase susceptibility to enamel decalcification.

The effect of hydrochloric acid and sodium hypochlorite on fracture resistance of orthodontic self-cure acrylic base.

Background: Patient cooperation is necessary for treatment success in removable orthodontics. Every factor has an adverse effect on appliances appearance can impede appliance wearing. This study investigated the effect of immersion in household cleaner and bleach liquids on fracture resistance of self-cure orthodontic acrylic resins.

Effect of immersion in hydrochloric acid and sodium hypochlorite and autoclave sterilization on the force characteristics of orthodontic nickel-titanium open coils.

Background: Nickel-titanium (NiTi) open coils are common tools in fixed orthodontic treatments to apply light and continuous forces. Their favorable mechanical properties and their relatively high cost have prompted many clinicians to decide to reuse them.

Aim: The present study aimed to evaluate the effect of 10% hydrochloric acid (HCl) and 5.

Chair time saving method for treatment of an impacted maxillary central incisor with 15-month follow-up.

Maxillary permanent incisors have a major role in facial esthetics. Impaction of them has great adverse effect on smile and causes serious concerns in patient and parents. Physical barriers (e.

Bilateral en-masse distalization of maxillary posterior teeth with skeletal anchorage: a case report.

Objective: The aim of this study was to introduce a new method for bilateral distal movement of the entire maxillary posterior segment.

Case Report: A 17-year-old girl with Class I skeletal malocclusion (end-to-end molar relationships, deviated midline and space deficiency for left maxillary canine) was referred for orthodontic treatment. She did not accept maxillary first premolars extraction.

Non-compliance Appliances for Upper Molar Distalization: An Overview.

Tooth Size Arch-length Discrepancy (TSALD) is a common problem in orthodontics. Its clinical signs are tooth crowding, impaction and incisor proclination. The treatment options are dental arch expansion or tooth mass reduction (stripping or extraction).

The effect of multiple processing and re-use on orthodontic mini-screw torque values.

Background: Reusing orthodontic mini-screws would reduce treatment cost and lead to more use of mini-screws and improvement of orthodontic treatments. This study has assessed the effects of reprocessing and reusing the titanium mini-screws on their maximum insertion, removal and fracture torque (FT).

Materials And Methods: In this experimental study, 20 titanium mini-screws (1.

The effect of insertion angle on orthodontic mini-screw torque.

Background: Primary stability is an important factor for the clinical success of orthodontic mini-screws. The present study made an attempt to evaluate the effect of insertion angle changes on the maximum insertion and removal torque of orthodontic mini-screws.

Materials And Methods: In this experimental study, 72 mini-screws (Dual Top Anchor System, Jeil, 1.

A processing method for orthodontic mini-screws reuse.

Background: The possibility of mini-screws reuse would reduce treatment cost. The aim of this study is to introduce a new method (application of phosphoric acid 37% for 10 minutes followed by sodium hypochlorite 5.25% for 30 minutes) for cleansing of mini-screws and assessing the efficacy of this method.

Forced eruption of adjoining maxillary premolars using a removable orthodontic appliance: a case report.

Forced eruption can be performed in teeth with caries, fracture, resorption or perforation in the cervical third of the root or isolated teeth with one- or two-walled vertical periodontal defects. The purpose of this case report is to introduce an innovative orthodontic appliance which enables forced eruption. This appliance is easy to fabricate, cost-effective and very effective in forced eruption of non-restorable teeth.
