Space Closure with Different Appointment Intervals: A Split-mouth Randomized Controlled Trial.

Background: Canine retraction has been successful with various force systems and retraction techniques. The appointment interval for force reactivation in canine retraction along the archwire is 4-8 weeks.

Aims: The aim was to evaluate the effect of different reactivation intervals on the rate of space closure.

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.

Orthodontic management of a developing dentigerous cyst related to lower second molar: a case report.

The dentigerous cyst is a developmental odontogenic asymptomatic cyst, that is associated with the crown of an unerupted or impacted tooth. Early diagnosis is important to avoid any future complications and choose the best treatment option. The purpose of this case report is to describe the management of a dentigerous cyst related to lower second molar in a young female patient using orthodontic traction as a conservative treatment approach.

Does Presurgical Taping Change Nose and Lip Aesthetics in Infants with Unilateral Cleft Lip and Palate? A Randomized Controlled Trial.

Background: The aim of this randomized controlled trial was to assess the effectiveness of taping alone in changing nose and lip aesthetics in infants with unilateral complete cleft lip and palate before and after surgical lip repair.

Methods: The study design was a prospective, balanced, randomized, parallel-group, single-blinded, controlled trial. All the steps were carried out in the Department of Orthodontics of Cairo University in Egypt.

Effectiveness of a Novel 3D-Printed Nasoalveolar Molding Appliance (D-NAM) on Improving the Maxillary Arch Dimensions in Unilateral Cleft Lip and Palate Infants: A Randomized Controlled Trial.

Objective: The aim of the current study was to introduce and measure the effectiveness of a new 3D-printed nasoalveolar molding (D-NAM) appliance on improving the maxillary arch dimensions (MADs) in infants with unilateral complete cleft lip and palate (UCLP) before surgical lip repair.

Design: A prospective, balanced, randomized, parallel groups, single-blinded, controlled trial.

Setting: All the steps of the current study were carried in the Department of Orthodontics, Cairo University in Egypt.

Using a single cone-beam computed tomography scan to obtain full occlusal details, with the mandible in centric relation and maximum intercuspation.

Introduction: One obstacle with the implementation of digital technology in orthodontics is the acquisition of occlusal details while maintaining the mandible in the full interdigitation position. With 1 cone-beam computed tomography (CBCT) scan of the patient and 1 digital scan of the patient's dental models in occlusion, it might be possible to obtain full occlusal details and generate 2 volumes, with the mandible in centric relation and maximum intercuspation positions. The purpose of this article was to describe the technique.

Revisiting the Factors Underlying Maxillary Midline Diastema.

Aim. The aim of this study is to analyze the etiological factors underlying the presence of maxillary midline diastema in a sample of orthodontic patients. Materials and Methods.

Accuracy and reliability of cone-beam computed tomography measurements: Influence of head orientation.

Introduction: The purpose of this research is to determine the accuracy and reliability of measurements obtained from 3-dimensional (3D) cone-beam computed tomography (CBCT) for different head orientations.

Methods: Stainless steel wires were fixed to a dry skull at different places. The skull was scanned by using CBCT in the centered and 5 other positions.

Miniscrew implant-supported maxillary canine retraction with and without corticotomy-facilitated orthodontics.

Introduction: The purpose of this study was to clinically evaluate miniscrew implant-supported maxillary canine retraction with corticotomy-facilitated orthodontics.

Methods: The sample consisted of 13 adult patients (5 men, 8 women; mean age, 19 years) exhibiting Class II Division 1 malocclusion with increased overjet requiring the therapeutic extraction of the maxillary first premolars, with subsequent retraction of the maxillary canines. Corticotomy-facilitated orthodontics was randomly assigned to 1 side of the maxillary arch at the canine-premolar region, and the other side served as the control.

Four curious cases of cone-beam computed tomography.

Cone-beam computed tomography (CBCT) has become popular, and its many inherent advantages are indisputable. Nevertheless, CBCT is prescribed cautiously because the radiation dosage is higher than that of conventional radiography. When and to what extent should CBCT be prescribed for orthodontic patients? The purpose of this article is to present 4 curious cases in which a considerable discrepancy was found between the conventional panoramic radiograph and the CBCT view.

Methods for managing 3-dimensional volumes.

The introduction of 3-dimensional (3D) volumetric technology and the massive amount of information that can be obtained from it compels the introduction of new methods and new technology for orthodontic diagnosis and treatment planning. In this article, methods and tools are introduced for managing 3D images of orthodontic patients. These tools enable the creation of a virtual model and automatic localization of landmarks on the 3D volumes.

Three-dimensional dental measurements: An alternative to plaster models.

Introduction: The aim of this study was to compare the accuracy of dental measurements taken with calipers on plaster dental casts and those from computed tomography scans of the dentition with a dental measurement program.

Methods: The sample consisted of plaster dental models of 34 orthodontic subjects. Dental arch measurements, including mesiodistal widths of teeth, arch widths, arch lengths, arch perimeters, and palatal depths were made with the calipers.

Loss of anchorage of miniscrews: a 3-dimensional assessment.

Introduction: Miniscrews have exponentially empowered the orthodontic anchorage armamentarium. However, the behavior of miniscrews under loading has not yet been fully investigated.

Methods: Forty miniscrews were used for retraction of the maxillary and mandibular canines into the spaces of extracted first premolars.

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.
