Position and root resorption of the incisors following anterior segment retraction using friction versus frictionless mechanics: A randomised controlled trial.

Aim: To evaluate the three-dimensional position and root resorption of incisors after anterior segment retraction (ASR) using friction versus frictionless mechanics.

Participants And Methods: Thirty female patients (13-18 years) with bimaxillary protrusion were randomly allocated into two groups. In the intervention group, ASR was undertaken using an elastomeric chain rendering 160 g/side extending between mini-screw implant and a hook crimped on 0.

Effect of low-level laser therapy on en masse retraction in females with bimaxillary dentoalveolar protrusion : A single-center randomized clinical trial.

Background: Acceleration of tooth movement has gained remarkable attention during the last decade. The aim of this study was to evaluate the effect of low-level laser therapy (LLLT) on en masse retraction of upper anterior teeth in adult women with bimaxillary dentoalveolar protrusion.

Materials And Methods: In this two-arm parallel trial, 36 women with bimaxillary dentoalveolar protrusion were randomly divided into two equal groups.

Effectiveness of low frequency vibration on the rate of canine retraction: a randomized controlled clinical trial.

To investigate the effectiveness of AcceleDent Aura vibrating device on the rate of canine retraction. Thirty-two patients requiring extraction of upper first premolars and canine retraction were randomly allocated with a 1:1 ratio into either no-appliance group or the AcceleDent Aura appliance group. Canine retraction was done applying 150gm of retraction force using NiTi coil springs on 16 × 22 stainless steel archwires.

Evaluation of the rate of anterior segment retraction in orthodontic patients with bimaxillary protrusion using friction vs frictionless mechanics: a single-center, single-blind randomized clinical trial.

Objectives: To evaluate the effect of friction vs frictionless mechanics on the rate of anterior segment retraction (ASR) in patients with bimaxillary protrusion.

Materials And Methods: Thirty females (18.3 ± 3.

Effect of low-level laser therapy on the time needed for leveling and alignment of mandibular anterior crowding.

Objectives: To assess the effect of low-level laser therapy (LLLT) on overall leveling and alignment time of mandibular anterior crowding and associated pain after initial archwire placement.

Materials And Methods: Thirty-two females (18-25 years) with mandibular anterior crowding were randomly allocated into laser and control groups. Eligibility criteria included Angle Class I molar relationship and Little's irregularity index (LII) from 4 to 10 mm.

Root resorption associated with maxillary buccal segment intrusion using variable force magnitudes.

Objectives: To compare the root resorption resulting from miniscrew-supported maxillary posterior dentoalveolar intrusion using two different force magnitudes.

Materials And Methods: Adult patients with skeletal open bite, indicated for maxillary posterior dentoalveolar intrusion, were recruited and randomly assigned to the comparison or intervention groups. The comparison group involved applying 200 g of intrusive force per segment, which measured 20 g per root, while this force was 400 g per segment in the intervention group, measuring 40 g per root.

Comprehensive comparison of canine retraction using NiTi closed coil springs vs elastomeric chains.

Objectives: To compare canine retraction using NiTi closed coil springs vs elastomeric chains comprehensively in a split-mouth randomized controlled trial.

Materials And Methods: The canines in 64 quadrants were randomly retracted into the first premolar extraction spaces using NiTi closed coil springs or elastomeric chains, in the maxilla and mandible. The retraction force was 150 g.

Force magnitude as a variable in maxillary buccal segment intrusion in adult patients with skeletal open bite.

Objectives: To compare the effects of two different force magnitudes on maxillary posterior segment intrusion using mini-screws. The null hypothesis was that there would be no difference between the two force magnitudes.

Materials And Methods: Adult patients with skeletal open bite and a dental open bite ranging from 3 to 8 mm were recruited for this trial.

The Effect of Local Pharmacological Agents in Acceleration of Orthodontic Tooth Movement: A Systematic Review.

Aim: Acceleration of orthodontic tooth movement has gained a massive interest to decrease the total treatment time. Local pharmacological agents might be used for that purpose as a practical, effective and inexpensive alternative. A systematic review was achieved to evaluate the evidence in that topic.

Three-dimensional imaging for indirect-direct bonding.

The aim of this article is to introduce a new concept of bracket positioning with special consideration to root axes. Cone-beam computed tomography imaging and computer-aided manufacturing were used to produce stereolithographic trays for indirect-direct bonding.

Growth changes in the soft tissue profile of Yemenis females: A cross-sectional study.

Aim: To investigate the changes in soft tissue parameters of three age groups of untreated Yemenis females.

Materials And Methods: The sample comprised 300 Yemeni females which were randomly selected and divided according to age into three equal groups (Group I: 7.34 ± 0.

Corticotomy-facilitated orthodontics using piezosurgery versus rotary instruments: an experimental study.

Objective: The aim of this study was to evaluate corticotomy-facilitated orthodontics (CFO) using piezosurgery versus conventional rotary instruments.

Materials And Methods: Ten healthy adult male mongrel dogs of comparable age with a complete set of permanent dentition with average weights between 13-17 kilograms were used. CFO using conventional rotary instruments versus piezosurgery was performed on each dog in a split mouth design.

Tooth movement into distraction regenerate: when should we start?

Introduction: The aim of this study was to evaluate clinically, radiographically, and histologically orthodontic tooth movement into bone regenerate after mandibular distraction osteogenesis to elucidate the optimal timing for initiating tooth movement.

Methods: The study sample consisted of 9 male mongrel dogs. An average edentulous space of 9 mm was created by using a custom-made bone-borne distractor fixed on the mandibular corpus of each dog.

Do alveolar bone defects merit orthodontists' respect?

Aim: To investigate the incidence and distribution of alveolar bony defects in the mandibular anterior area.

Methods: A flap procedure was performed to expose the labial alveolar bone of the mandibular anterior area of 32 patients. The presence of alveolar defects including dehiscences and fenestrations were recorded.
