The Strategy For Uprighting A Deep Horizontally Impacted Mandibular Second Molar, Hui-Wen Cheng, Chia-Tze Kao, Chih-Chen Chou, Ching-Yi Tsai, Hsing-Yeh Shen, Wen Ken Tai

Taiwanese Journal of Orthodontics

An orthodontic treatment that involves uprighting of deep horizontally impacted mandibular second molars (MM2) can be a challenging procedure. This case report demonstrates an approach to correct an impacted MM2, specifically in a 21-year-old male patient who presented with a Class II division 2 malocclusion, deep bite, and bilateral maxillary second molars with buccal crossbite. Correction of the impacted MM2 had been achieved using a ramus temporary anchorage device (TAD), which applied pulling and extruding forces along with an uprighting moment. Addressing the deep bite required proclination of incisors, utilization of an intrusion arch for maxillary incisors, and implementation of …

Effects Of Full-Time Versus Part-Time Clear Aligner Wear On Periodontal Health, Pain And Compliance In Orthodontic Patients, Mohamed Adel Afify, Ahmed Medhat Eltimamy, Fouad A. El Sharaby, Hala Monir Abdelmajeed

Future Dental Journal

INTRODUCTION: Clear aligner treatment's main drawback is that the patient decides how long to wear them each day. For clear aligner therapy to be successful, compliance is essential. A poor treatment outcome would arise from noncompliant patients.

METHODS: The study was a randomized clinical trial of 2 parallel groups (7 patients per group) who underwent clear aligner orthodontic treatment having an age range of 17-24 years. A part-time group wore the aligners for 16 hours per day and a full-time group wore the aligners for 22 hours per day. The study investigated the first eight aligners of the treatment. Compliance …

Early Intervention Within Orthodontics: The Sociological Aspects, Trenton Hammond 2024 University of Nebraska-Lincoln

Early Intervention Within Orthodontics: The Sociological Aspects, Trenton Hammond

Honors Theses

Orthodontic treatment is one of the final phases of dental treatment. Its use is to provide aesthetics in some cases, yet the quality-of-life aspect that it can provide is greatly underestimated. Orthodontic care can provide proper function of teeth, improve facial structure, avoid tooth decay/loss, and improve gum health (AAO, 2024). Within this research the overarching goal is to understand the sociological aspects of families looking to start orthodontic care, what the reasons behind starting or not starting are, and providing information to the public about orthodontics that may be misunderstood or might push people away from searching for orthodontic …

Effect Of Taper And Pitch On Nickle-Titanium File With Variable Cross Section To Its Cyclic Fatigue (In Silico Study), Yustika Chrysandra, Tunjung Nugraheni, Wignyo Hadriyanto

Journal of Dentistry Indonesia

The geometric design of an endodontic file includes cross-sectional shape, taper, and pitch. NiTi endodontic files of OneCurve (MicroMega) are made of two variations of cross-sectional shape, that is, double-s shaped and triple helix. Various kinds of modifications were made to increase the resistance of the NiTi endodontic files from fracture. Cyclic fatigue is the most common factor that causes a fracture of the endodontic file. Objective: The purpose of this study was to obtain a NiTi endodontic file design that has the best cyclic resistance value based on its taper size and number of pitch. Methods: This …

Annual Research Symposium

Orthodontic treatment goes beyond mere cosmetic enhancement; it significantly impacts various aspects of an individual's quality of life. Beyond the physical benefits of improved oral function and prevention of dental issues, orthodontics also yields profound psychological benefits. Aligned teeth enhance self-confidence, reduce social anxiety, and contribute to better relationships and professional opportunities. Moreover, addressing dental concerns through orthodontic treatment reduces psychological distress and promotes overall happiness and satisfaction. Real-life case studies vividly illustrate the transformative effects of orthodontic interventions, emphasizing the importance of considering quality of life outcomes in dental care.

Taiwanese Journal of Orthodontics

The treatment of ankylosed incisor is challenging for orthodontists, necessitating accurate diagnosis, well-considered treatment planning, and close collaboration among interdisciplinary teams to achieve favorable esthetic and periodontal outcomes. For ankylosed cases, accurate diagnosis depends on detailed clinical examination and 3D radiographic images. This case report described the treatment of a bimaxillary protrusive female with an ankylosed maxillary left central incisor. The decision regarding treatment was based on the severity of dental ankylosis and replacement root resorption. Each treatment plan comes with its own set of advantages and disadvantages. In this case, the decoronation treatment plan and prosthesis was implemented, resulting …

Taiwanese Journal of Orthodontics

Cleidocranial Dysplasia (CCD) is a syndrome that causes skeletal growth disturbances. The impaction of many permanent teeth and several supernumerary teeth are among the dental problems of patients with this syndrome. This patient was a 14 y/o girl with CCD syndrome. She was skeletal Cl III with reverse overjet; many impacted teeth, and several supernumerary teeth. Orthodontic treatment was done in two stages. In the first stage, supernumerary anterior teeth were extracted, and the impacted teeth were exposed for traction. In the second stage, posterior supernumerary teeth were removed, and upper canines and posterior impacted teeth were exposed for forced …

A Coronectomy And Orthodontic Protraction Of An Impacted Lower Third Molar Compressed To The Inferior Alveolar Nerve: A Case Report, Johnson Hsin-Chung Cheng, Daniel De-Shing Chen, Bou-Yue Peng, Pei-Hsuan Chen

Taiwanese Journal of Orthodontics

Background: Neurological damage may occur during a third molar extraction procedure when the tooth root is near the mandibular canal. Although the incidence of this complication is low, a great range of variability has been reported in the literature. Several methods to reduce or eliminate this complication have been proposed, such as orthodontic-assisted extraction, extraction of the second molar, or an intentional odontectomy. Objective: The objective of this case report is to present a low risk extraction procedure: a coronectomy with forced eruption (COFE) to avoid potential neural damage when removal of lower wisdom tooth compressing inferior alveolar nerve in …
