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 …

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 …

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 …

Non-Extraction Orthodontics In Severe Open Bite With Disc Plication Surgery Of The Temporomandibular Joint, Jessica Chia-Yi Wang, Meng-Yen Chen, Kuan-Yu Lin, Tung-Yiu Wong, Chen-Jung Chang

Taiwanese Journal of Orthodontics

Open bite malocclusion is among the most challenging orthodontic deformities to correct. Among the etiological factors of anterior open-bite, degenerative change in temporomandibular joints (TMJs) is the most difficult condition to manage. The most appropriate treatment modality for TMJ disorder with disc displacement remains controversal. Disc repositioning surgery is a treatment option when conservative treatment has failed to resolve symptoms. We presented a patient had history of gradual bite opening associated with joint stiffness and clicking. She received occlusal splint therapy for more than 10 years, and the occlusion was stable for 1 year before orthodontic treatment was initiated. Based …

Nasoalveolar Molding ; A Rise In Early Management Of Newborn Patient With Cleft Lip And Palate, Reeya Agrawal, Dr Pallavi Daigavane, Dr Amit Reche

International Arab Journal of Dentistry

Orofacial clefts are one of the most frequent congenital oral and maxillofacial abnormalities. When these babies are roughly three months old, lip rebuilding , also known as cheiloplasty, is a critical concern. In several cleft facilities ,To improve the treatment success, Presurgical Nasoalveolar Molding (NAM) has been included in the therapy protocol. In patients with cleft lip and palate, this technique is routinely used to bring the alveolar segments in to normal alignment and improve nasal symmetry.The advantages of utilising this approach as part of a treatment plan for newborns born with cleft lip and palate will be discussed in …
