Resolution Of Severe Lateral Open Bite With Surgically Enhanced Orthodontic And Myofunctional Therapies, Daniel Kuncio D.D.S., Maria Karpov D.M.D.

The New York State Dental Journal

Patients often present to our practices with dental relapse of previous orthodontic treatment. Many times, the underlying skeletal and/or functional problems leading to the malocclusion were not addressed, causing the teeth to revert to their initial positions, even with good retainer wear. This patient presented with a severe lateral open bite and complained of problems chewing on his right side.

Previous orthodontic treatment with fixed orthodontics appliances and vertical elastics proved to be unstable. We recommended a treatment plan with surgically assisted rapid palatal expansion (SARPE) to correct the skeletal maxillary constriction and provide more tongue space, followed by surgically …

Long-Term Interdisciplinary Management Of Severe Vertical Bony Defects Using Periodontal Accelerated Osteogenic Orthodontics (Paoo), Chun-Han Su, Huei-Mei Tsai, Yi-Min Liu, Yuen-Yung Tsang, Yu-Ling Cheng

Taiwanese Journal of Orthodontics

Background: Management of severe malocclusion in patients with chronic periodontitis poses significant challenges due to compromised periodontal support and alveolar bone loss. Periodontally accelerated osteogenic orthodontics (PAOO) may facilitate tooth movement while promoting bone regeneration in such cases.

Case presentation: A 33-year-old male with chronic periodontitis and severe malocclusion presented for orthodontic correction. Initial treatment included comprehensive periodontal therapy—oral hygiene control, open-flap debridement, and bone grafting—prior to orthodontic intervention. Congenital absence of tooth 12 resulted in mesial drift, and teeth 17, 24, and 27 were extracted due to poor prognosis. Despite initial periodontal improvement, inflammation and labial plate collapse at …

Correction Of Facial Asymmetry Using Bilateral Sagittal Split Osteotomy Combined With Anterior Mandibular Midline Split And Genioplasty, Po-Yu Yang, Chia-Tze Kao, Yi-Chieh Chen, Wen-Ken Tai

Taiwanese Journal of Orthodontics

Facial asymmetry accounts for approximately two-thirds of orthognathic surgical patients and may involve discrepancies in any of the three spatial planes. Conventional bilateral sagittal split osteotomy (BSSO) has limitations in correcting patients with significant discrepancies in bilateral ramus angles. This paper proposes a novel surgical approach for the correction of facial asymmetry using BSSO combined with an anterior midline mandibular split osteotomy and genioplasty.

A 30-year-old woman presented with a skeletal Class III pattern, occlusal canting, and a 3-mm deviation of the chin to the right. Intraoral examination revealed an anterior crossbite, dental midline deviation, and a left Angle’s Class …

Taiwanese Journal of Orthodontics

Purpose: This article introduces a digital workflow for creating a miniscrew-assisted rapid palatal expander (MARPE) guide, to virtually determine the proper MARPE position and to precisely transfer it into the reality. Materials and Methods: A digital workflow was established by the following steps: (1) generating a digital model with palatal soft tissue from the digital scan, (2) isolating teeth on the digital model from the CBCT file for band size try-in using AI software (DentalSegmentator), (3) constructing a model with four parallel cylinders simulating the MARPE screws’ pathways, (4) superimposing the three models to determine the proper MARPE position, (5) …

To Extract Or Not To Extract: On What Basis Do We Make That Decision? (Part Ii), Ib Leth Nielsen

Taiwanese Journal of Orthodontics

The most common extraction pattern in orthodontic patients with crowding of the teeth is the four first bicuspids. This is usually done in cases with severe crowding or bimaxillary protrusion. In some instances, orthodontists have decided, instead of extracting the first bicuspids, to extract the second bicuspids, for various reasons that we shall discuss in this review. Several other extraction patterns have also been implemented in the past, including second molars, lower incisors, and even asymmetric extractions. In this review, we shall discuss the pros and cons of each of these choices. In some patients, clinicians have even decided to …

Methods: A retrospective computational audit was designed around trial registries (e.g., ClinicalTrials.gov and other major registries used in orthodontics) and bibliographic records. Registry entries marked completed were programmatically screened for publication linkage using identifier matching (e.g., registration IDs) and document-similarity approaches aligned with prior registry-publication linkage research. Trial-level transparency indicators included (i) prospective vs retrospective registration, (ii) completion to publication lag, (iii) presence/absence of posted results in …

Regulatory Signal Mining Of Orthodontic Device Adverse Events: A Maude-Derived Taxonomy And Severity Triage For Clear Aligners And Fixed Appliances, Nazmi Duka, Dana Faghih, Shankargouda Patil, Shilpa Bhandi, Frank Licari

Annual Research Symposium

Objective: To build and validate a practical, orthodontics-specific adverse event taxonomy and severity triage framework using publicly available regulatory narratives, enabling rapid surveillance of high-risk event patterns across clear aligners and common orthodontic appliances.
Methods: A retrospective computational audit was conducted using U.S. FDA MAUDE medical device report narratives related to orthodontic appliances, with a focus on clear aligners (including Invisalign and direct-to-consumer sequential aligners). Narrative reports were normalized and grouped into clinically interpretable event families (airway compromise, hypersensitivity/allergic reactions, ingestion/aspiration, soft-tissue injury, periodontal/tooth injury, and occlusal/bite changes). A lightweight natural-language processing pipeline (keyword+pattern rules with clinician-informed adjudication) was used …

The Effect Of Social Media On Orthodontics: The Patient And Practitioner Perspective, Corban Ward, Jacob Marx, Man Hung, Samuel Dyal, Alicia Parry

Annual Research Symposium

Introduction Social media now shapes how people find information, connect and form identity. It increasingly influences cultural standards around  health and appearance. In orthodontics, these platforms are reshaping public perceptions, attitudes and treatment decisions. This review synthesizes existing research on social media’s impact on how people view and choose orthodontic care.

Methods A PRISMA guided review searched PubMed, Scopus, and Web of Science for  peer-reviewed English-language studies published between 2015 and 2025.

Long-Term Follow-Up Of Midface Hypoplasia In A Patient With Cleft Lip And Palate, Jui-Jen Fang, Hui-Ching Yu, Li-Ling Cheng, Yu-Jen Chang

Taiwanese Journal of Orthodontics

Introduction: Severe midface hypoplasia is a common craniofacial deformity in patients with cleft lip and palate (CLP), often linked to functional impairment and esthetic concerns. Although surgical and orthodontic advances have improved outcomes, long-term stability remains challenging. This report presents the management of a bilateral CLP patient and evaluates stability after more than 12 years of follow-up. Diagnosis: A 31-year-old male with bilateral CLP showed a concave facial profile, widened lip scars, reverse overjet of –30 mm, complete crossbite, and missing teeth (12, 22, 36). Palatally displaced premolars (15, 25) produced an hourglass-shaped arch. The diagnosis was skeletal Class III …

Treatment Of Skeletal Class Iii Malocclusion With Spaced Arch And Anterior Crossbite Using Low-Hysteresis Improved Super-Elastic Ti-Ni Alloy Wire (Isw), Szu-Ying Yu, Yuag-Hou Chen, Ching-Yu Yang, Jian-Hong Yu

Taiwanese Journal of Orthodontics

This article presents the orthodontic treatment of a non-surgical, non-growing skeletal Class III malocclusion using an Improved Super-elastic Ti-Ni Alloy Wire (ISW), developed by the Institute of Science Tokyo (formerly Tokyo Medical and Dental University). Teeth 28 and 48 were extracted, and ISW with long Class III intermaxillary elastics (L3–U6) was applied to eliminate anterior occlusal interference, retract the mandible, and induce a clockwise rotation of the mandibular plane. In addition to mandibular space closure, the deviated dental midline and chin asymmetry were corrected using elastic chains and intermaxillary elastics. Proper arch coordination, space management, and midline alignment were achieved, …

Orthodontic Space Closure And Third Molar Uprighting For Simultaneous Maxillary And Mandibular Molar Loss On The Same Side, Chun-Yi Huang, Yuan-Hou Chen, Ching-Yu Yang, Jian-Hong Yu

Taiwanese Journal of Orthodontics

This case report describes the successful non-surgical orthodontic management of a complex Class I malocclusion characterized by unilateral posterior tooth loss and functionally induced facial asymmetry. A 28-year-old male patient presented with a non-restorable maxillary first molar (#26) and a missing mandibular second molar (#37). The resulting occlusal discrepancy contributed to a mandibular functional shift and facial asymmetry. The patient declined prosthetic and surgical options, prompting a conservative orthodontic approach.

The treatment plan incorporated third molar protraction and upright to substitute for the missing second molar, combined with occlusal rehabilitation to correct the asymmetry. Space closure was achieved using elastic …

Nonsurgical Orthodontic Management Of A Severe Skeletal Class Ii Malocclusion Using A Modified Intrusive Arch, Ting-Wei Liu, Chun-Liang Kuo, Chun-Hsiu Yang

Taiwanese Journal of Orthodontics

Treating skeletal Class II malocclusion in non-growing patients remains a significant challenge in contemporary orthodontics. Treatment options range from dental camouflage, often involving extractions, to combined orthodontic–surgical approaches. In this case, orthodontic camouflage with extractions was selected to manage a severe skeletal Class II discrepancy in a 28-year-old female patient. A modified intrusive arch was employed to achieve simultaneous retraction and intrusion of the maxillary anterior teeth, effectively reducing excessive overjet. The biomechanical system of the modified intrusive arch generates an anterior intrusive force, a posterior extrusive force, and a posterior tip-back moment. The combined use of Tip-Edge Plus brackets …
