Abstract Ankylosis of an maxillary central incisor following dental trauma can be a major obstacle in orthodontic treatment, particularly in skeletal Class II patients when both retraction and impaction are required. This report describes a 21-year-old female with skeletal Class II malocclusion (ANB 10°), flared maxillary central incisors, and protrusive lips, with a history of dental trauma. Radiographs confirmed ankylosis of tooth 11 and external root resorption of tooth 21. The initial plan involved a non-surgical camouflage approach with four first premolar extractions, but treatment was halted when ankylosis prevented canine retraction. A single-incision, piezoelectric-assisted segmental osteotomy under local anesthesia was then carried out to retract and impact the ankylosed incisor segment while maintaining blood supply through intact facial and palatal pedicles. Gradual movement was achieved with power chains, followed by alignment and establishment of a functional occlusion. The active treatment time was 48 months. Post-treatment records showed a reduction in overjet from 8.0 mm to 2.0 mm, overbite from 6.5 mm to 2.0 mm, and an ANB change from 10.0° to 5.5°, with improved mandibular position and incisor inclination. Radiographs confirmed complete bone healing and preservation of gingival papillae. The patient's profile improved from convex to straight, with stable occlusion and no evidence of necrosis or other major complications. This case demonstrates that a minimally invasive, piezoelectric-assisted segmental osteotomy can be an effective and aesthetic-preserving option for treating ankylosed maxillary central incisors in skeletal Class II patients, offering precise bone removal, stable results, and minimal surgical trauma.
Abstract Introduction This study aimed to comparatively evaluate the evolution, current status, and emerging trends of research on miniscrew-assisted rapid palatal expansion (MARPE) and surgically assisted rapid palatal expansion (SARPE). Methods Articles and reviews related to MARPE and SARPE were retrieved from the Scopus database. A total of 202 publications on MARPE and 347 on SARPE were analyzed using bibliometric methods. Bibliometric analyses were performed with the Bibliometrix (R) and VOSviewer software. The relationships between the number of publications, citation counts, and gross domestic product (GDP) per capita were examined using Pearson correlation and linear regression analyses ( P < 0.05). Results The number of MARPE-related publications showed an average annual increase of 38.86% (SARPE: 10.38%). The mean number of citations per publication was 20.16 in the SARPE field and 13.53 in the MARPE field. The annual citation rate was 2.53 for MARPE and 1.64 for SARPE. Regarding publication output, the United States, Brazil, and South Korea were the leading countries in MARPE research, whereas Brazil, Turkey, and Germany were most prominent in SARPE. A strong positive correlation was found between GDP per capita and the mean number of citations per article (MARPE r = 0.73; SARPE r = 0.70). Conclusions The SARPE field possesses an established literature base primarily focused on surgical procedures. In contrast, MARPE has rapidly emerged as a growing field characterized by its minimally invasive nature and digital-oriented advancements.
Abstract This case report describes a simple method for single tooth intrusion using a modified thermoform aligner and an orthodontic elastic. This technique allows for an aesthetic and monetarily beneficial solution for the patient. The biomechanical advantage of this technique leaves the adjacent dentition unaltered and does not require multiple appliances or attachment, like other clear aligner techniques. In addition, it may be used as an adjunctive in clear aligner therapy.
Abstract Learning about and assessing any airway-related issues is crucial for each patient who comes to the orthodontic office. An essential part of the decision-making process should be assessing the impact of orthodontic treatment on the upper airway's dimensions. There is strong evidence that various therapeutic techniques, including RME, functional jaw orthopaedics, and especially maxillomandibular advancement treatments, have positive associations and effects on airway-related problems. In this review article, we have tried to give a comprehensive description of the various methods for assessing the airway and its clinical consequences in orthodontics. An essential part of the decision-making process should be assessing the impact of orthodontic treatment on the upper airway's dimensions.
Abstract Impacted canines present significant diagnostic and therapeutic challenges in orthodontics, with potential consequences including root resorption, malocclusion, and compromised aesthetics if left untreated. This review illustrates current advances in the diagnosis and management of impacted canines, emphasizing an evidence-based approach. Emerging diagnostic modalities, particularly cone beam computed tomography (CBCT), have allowed precise three-dimensional localization and assessment of root proximity, although their use must be justified against radiation exposure. Orthodontic strategies, including traction biomechanics for effective traction and minimizing adverse effects on adjacent teeth. Surgical management techniques, including open and closed exposure protocols, are discussed with attention to periodontal health and long-term outcomes. Additionally, the use of orthodontic miniscrews as skeletal anchorage has enhanced control over tooth movement, reducing unwanted side effects and improving predictability. Collectively, these advances facilitate safer, more efficient, and more esthetically favorable results. However, the ultimate treatment goal remains the establishment of a functionally stable occlusion and an attractive smile, maintained through careful long-term retention.
