Introduction: The dentoskeletal effects of clear aligner treatment (CAT) with Invisalign vs temporary skeletal anchorage device-anchored Sydney intrusion spring (SIS) were compared in consecutively treated growing patients with anterior open bite using cone-beam computed tomography scans.
Methods: Fifteen adolescents treated exclusively with Invisalign, and 14 with SIS (first-phase treatment) were assessed retrospectively. Rigid-wise, voxel-based registration of pretreatment and posttreatment cone-beam computed tomography scans were performed using the anterior cranial base, maxillary plane, and mandibular body as reference regions.

Introduction: The primary objective of this study was to assess the 3-dimensional position of the mandibular canal (MC) in different craniofacial patterns to know about the safe placement of temporary skeletal anchorage devices using cone-beam computed tomography (CBCT). The secondary objectives were to assess sex differences and correlate the MC position with various factors.
Methods: This prospective, observational study was conducted on 90 patients, divided into 3 groups based on the sagittal pattern: skeletal Class I, Class II, and Class III.

Mandibular molar distalization is a complex orthodontic movement due to anatomic and biomechanical limitations. The opportunity to use a custom-made appliance with skeletal anchorage should be an advantageous alternative to traditional solutions: multiple extractions, interproximal reductions, vestibular inclination of incisal group. : A 14-year-old female patient with Class II malocclusion and ectopic upper and lower canines was treated in the lower arch with a custom-made appliance anchored on a mini-screw in the right buccal-shelf where the ectopy and crowding was severe.

Dental malocclusions are highly prevalent worldwide, negatively impacting patients' quality of life and leading to complex, often costly, orthodontic treatments. In Romania, the economic status of patients and the limited public funding for orthodontic care significantly influence treatment accessibility and choices. Advanced technologies, such as mini-implants (MIs), offer improved anchorage and treatment efficiency but are often underutilized due to financial constraints and variability in clinical training.

Background: The placement of Temporary Anchorage Devices (TADs) in the mandibular buccal shelf area is a common option for distalizing the lower arch. Therefore, the study of bone thickness and depth in this area is mandatory before planning TAD insertion. The aim of this study was to quantify the width and depth of the mandibular buccal shelf structure and examine its associations with sex, age, skeletal class and vertical pattern.
