This review, registered in PROSPERO (CRD42018102582), assessed the effect of temporary anchorage device placement on endodontic complications. A search strategy was followed to identify studies where any temporary anchorage devices contacted or were in proximity to tooth roots in humans. Studies with low possibility of bias and published in English or Latin-character languages were considered for inclusion. Ten studies were identified; five case reports, one clinical study and four studies with intentional injury, totalling 736 temporary anchorage devices in 327 patients. Complications may ensue following temporary anchorage device placement, whether or not root contact occurs. Chronic apical periodontitis developed when there was root injury involving the pulp; necrosis can also occur. When damage was limited to the periodontal ligament, cementum or dentine, repair occurred, normally within 12 weeks. Clinicians should be aware of the potential for endodontic complications during temporary anchorage device placement, as well as during orthodontic treatment.

In this case report, we show a strategic approach to prolonging the lifespan of pathologically migrated maxillary canines with a hopeless prognosis in a 57-year-old female patient, highlighting the potential of orthodontic management for middle-aged patients to enhance both occlusion and facial esthetics while minimizing the need for extensive prosthetic treatment. According to the visual treatment objective, the nonextraction treatment plan showed advantages in the type of orthodontic tooth movement and final occlusal relationship. Therefore, considering the favorable periodontal treatment results and single-root teeth, the hopelessly migrated maxillary canines were relocated, eliminating the existing trauma from occlusion.

: Achieving ideal anchorage is crucial in orthodontics for controlled tooth movement. Miniscrews (MSs) have improved skeletal anchorage, but freehand placement poses risks like root damage and limited precision. Guided techniques, including radiographic guides and computer-assisted methods (static [sCAS] and dynamic [dCAS]), were developed to enhance accuracy and safety.

This case report details the treatment of a 23-year-old female patient with Class II division 2 malocclusion with a Class II skeletal base due to a retrognathic mandible. The condition was further complicated by a complete overbite, absence of tooth #36, and a gummy smile. The Forsus appliance has shown to be effective in correcting Class II malocclusion in adult patients, with significant improvements in bite and facial esthetics.

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.
