Introduction: The purpose of the study was to scientifically test maxillary canine retraction assisted by miniscrew implant with corticotomy-facilitated orthodontics.
Materials And Methods: Fifteen patients (six males, nine females) who had Class II division malocclusion with enhanced overjet were included in the study. Maxillary first premolars were surgical displaced along with retraction of maxillary. In the canine-premolar region, corticotomy was performed on one side of the maxillary arch; the other side served as the control region. Over a 4-month follow-up span, the following variables were examined: plaque index, tooth movement intensity, attachment degree, gingival regression, molar anchorage failure, gingival index, and scope of testing.
Results: After 2 months, the canine retraction rate on the corticotomy side was more significant than on the control side by twice. The tooth movement rate steadily decreased to 1.6 times faster at the end of the 3 month and to 1.06 times faster at the end of the 4 month. No failure of molar anchorage occurred on either the controlled or nonoperated hand during canine retraction.
Conclusions: For people requiring orthodontic care with shortened treatment periods, corticotomy-facilitated orthodontics may be a viable treatment modality.

Background: The efficacy of clear aligner treatment (CAT) in space closure following premolar extraction (SCaPE) and its resistance to unwanted tooth movement remain uncertain. This systematic review aims to evaluate the efficacy, predictability, and resistance to unwanted tooth movement by CAT for SCaPE.
Methods: Pre-post studies, randomized, and non-randomized clinical trials were included.

Introduction: Micro-osteoperforation (MOP) is a minimally invasive technique aimed at accelerating orthodontic tooth movement (OTM) by stimulating localised bone remodelling. However, its impact on root resorption, alveolar bone levels, and inflammatory mediators such as interleukin-4 (IL-4) requires further investigation. This study assessed root resorption, alveolar bone changes, canine angulation, rate of retraction, and IL-4 expression associated with MOP-assisted canine retraction.

Objective: This study aimed to investigate the biomechanical effects of en-masse versus alternate retraction during aligner treatment in premolar-extraction cases.
Methods: Four finite element analysis models of maxillary first premolar extraction were created: Group I (en-masse retraction), Group II (canine distalization), Group III (incisor retraction) and Group IV (alternate retraction). Various aligner torque compensations (0°, 1°, 2°, 3°) were applied on the anterior teeth.

Introduction: Relative macroglossia may contribute to brachycephalic obstructive airway syndrome, the pathologic disorder associated with respiratory dysfunction commonly seen in brachycephalic dogs. Recent studies on brachycephalic dogs have demonstrated a relative macroglossia along with reduced air volume in the upper airway compared to non-brachycephalic dogs. Tongue reduction glossectomy may be a surgical option to address upper airway obstruction secondary to macroglossia.

Background And Objective: Optimizing orthodontic tooth movement while minimizing complications remains a primary goal for both clinicians and patients. This preliminary study evaluated canine retraction using the sliding technique on a round cross-section archwire, employing a hybrid archwire designed to enhance movement efficiency while controlling canine angulation during retraction. This hybrid design combines a rectangular anterior segment for incisor control with a round posterior segment to reduce friction during canine retraction, differing from conventional single-section wires.
