Open Bite: A Clinical Challenge For The Orthodontist (Part I), Ib Leth Nielsen

Taiwanese Journal of Orthodontics

The open bite malocclusion is challenging to most orthodontists in part because the etiology is poorly understood. In this review we will explain the multifactorial etiology of this malocclusion. The role of facial growth and function in the development of this malocclusion, and several other factors that often are contributing to this malocclusion. The etiology, diagnosis and some important treatment considerations in patients with open bite will be discussed.

10-Minute Ebd: Preferred Analgesia For Orthodontic Tooth Movement: Acetaminophen Or Nsaids?, Ryan N. Mcgovern

The Journal of the Michigan Dental Association

This 10-Minute EBD column explores the choice between acetaminophen and NSAIDs for managing pain during orthodontic tooth movement. The author presents a scenario involving a patient's discomfort after archwire adjustment and delves into the impact of tooth movement on the periodontium. The PICO question focuses on the effectiveness of NSAIDs and acetaminophen in controlling discomfort without impeding tooth movement. The literature search reveals varying recommendations on analgesics, with some studies favoring acetaminophen. The evidence suggests that acetaminophen and short-term celecoxib are suitable choices for orthodontic analgesia. However, caution is advised in extrapolating findings from animal studies to human conditions.

Orthognathic Surgery And Quality Of Life Outcomes: Findings From A Hospital-Based Patient Satisfaction Survey, Parth D. Shah Dds, Mph, Victor M. Badner Dmd, Mph, Benn Lieberman Dmd

The New York State Dental Journal

This study examined patient satisfaction and changes in quality of life (QoL) following the orthognathic surgery performed to treat severe dentofacial deformities. The short form of the oral health impact profile (OHIP-14) instrument was utilized to measure the negative impact related to severe dentofacial deformities on QoL. Ninety-five patients participated in this survey. Respondents reported significant reduction in the overall OHIP-14 score following the orthognathic surgery (p-value<0.0001). Approximately 92% reported post-operative resolution of their chief concerns. In conclusion, orthognathic surgery was found beneficial as it significantly reduced the negative impact of severe skeletal malocclusion on QoL of the patient we surveyed.

Artificial Intelligence In Dentistry, Orthodontics And Orthognathic Surgery: A Literature Review, Tania Arshad Siddiqui, Rashna Hoshang Sukhia, Dinaz Ghandhi

Section of Dental-Oral Maxillofacial Surgery

Artificial intelligence is the ability of machines to work like humans. The concept initially began with the advent of mathematical models which gave calculated outputs based on inputs fed into the system. This was later modified with the introduction of various algorithms which can either give output based on overall data analysis or by selection of information within previous data. It is steadily becoming a favoured mode of treatment due to its efficiency and ability to manage complex conditions in all specialities. In dentistry, artificial intelligence has also popularised over the past few decades. They have been found useful for …

The Effects Of The Covid-19 Pandemic On Postgraduate Endodontic Programs In The United States, Bianca Aboubakare, James Chen, Johnah C. Galicia

Orthodontics and Endodontics Theses

In December 2019, the coronavirus disease 2019 (COVID-19) was first identified as an acute infectious disease in Wuhan, China and subsequently led to an ongoing pandemic. At the onset of the pandemic, dental professionals were understood to face the greatest exposure risk to SARS-Cov-2 due to aerosolization of fluids from the oral cavity and respiratory airways . As a result, dental professionals, including academic institutions and their students and residents halted much of their operations to minimize exposure risks and potentially slow the spread of infection to peers and patients alike. Currently, there is little in the literature that describes …

Adaptations In Orthodontics For Current And Future Covid-19 Best Practices, Jordan Lamb

Theses and Dissertations

Purpose: To determine what adaptations orthodontists made in their practices during the COVID-19 pandemic in response to safety recommendations and to determine which of these adaptations orthodontists plan to continue to implement after resolution of the COVID-19 pandemic.

Methods: An original 34-question survey was sent by mail to a randomized and geographically proportionate selection of actively practicing orthodontic specialists (N = 1000). Questions asked orthodontists about the changes they made during the pandemic in four overarching categories (infection control, social distancing, appliance use, and tele-orthodontics) and whether they anticipated keeping those changes post-pandemic. The data were compared between categorical responses …

Automatic Cephalometric Landmark Detection On X-Ray Images Using Object Detection, Cheng-Ho King, Yin-Lin Wang, Chia-Ling Tsai

Publications and Research

We propose a new deep convolutional cephalometric landmark detection framework for orthodontic treatment. Our proposed method consists of two major steps: landmark detection using a deep neural network for object detection, and landmark repair to ensure one instance per landmark class. For landmark detection, we modify the loss function of the backbone network YOLOv3 to eliminate the constrains on the bounding box and incorporate attention mechanism to improve the detection accuracy. For landmark repair, a triangle mesh is generated from the average face to eliminate superfluous instances, followed by estimation of missing landmarks from the detected ones using Laplacian Mesh. …

Cbct Use In Orthodontic Residency Programs In Usa, Su Min Han

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: Cone beam computed tomography (CBCT) scans in dentistry have been up and coming forms of x-ray technology that allows cross-sectional images to form a comprehensive 3-dimensional representation of the mouth. While the typical use for CBCT imaging is reported to be for implant dentistry, there are many contexts in which it is indicated in orthodontics. There are various schools of thought regarding when CBCT is indicated for specific diagnosis of problems or general use in the collection of initial, progress and post-treatment orthodontic records. There are programs that follow the Radiology guidelines for taking CBCT scans10 and …

Passive Self-Ligating Brackets Vs. Conventional Brackets: Is There A Difference In The Transverse Dimension? A Systematic Review And Meta-Analysis, Justin Scott Tenbrook

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives:

Self-ligating brackets have risen in popularity in clinical orthodontics, but many claims made by their manufacturers have been made without substantial evidence. Any differences among the bracket types are very small when consulting new peer reviewed literature testing their differences. Nevertheless, self-ligating brackets are still purported to be able to increase the dental transverse dimension more effectively than conventional brackets. In 2018, Yang et al. performed a systematic review on the transversal changes, space closure, and efficiency of conventional and self-ligating appliances. Since then, there were several clinical trials published in the literature comparing the mandibular arch …

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study investigated the effects of the pitch (P) and thread shape on orthodontic miniscrew cortical bone microdamage. The relationship between microdamage and primary stability was examined. Ti6Al4V orthodontic miniscrews had custom-made thread heights (H) and pitch sizes and were classified into the following groups: HCPC (control); HCPN (with a narrower pitch); and HTPC (with a taller thread height) (HC = 0.12 mm; HT = 0.36 mm; PC = 0.60 mm; PN = 0.30 mm). The orthodontic miniscrews were inserted in the pilot hole of prepared 1.0-mm-thick tibia cortical bone, and the maximum insertion torque (MIT) and Periotest value (PTV) …

Expression Of Superoxide Dismutase 3 (Sod3) During Orthodontic Tooth Movement In Rats, Phanchanit Jindarojanakul

Chulalongkorn University Theses and Dissertations (Chula ETD)

Hypoxia induces reactive oxygen species (ROS) production in periodontal tissues. Superoxide dismutase 3 (SOD3) is an enzyme protecting cells from ROS. This study investigated SOD3 expression and function during rat orthodontic tooth movement (OTM) and in hypoxia-exposed rat PDL cells. OTM of right maxillary first molars were performed in Sprague-Dawley rats for 1 and 14 days (n = 6 per group). SOD3 and HIF-1α expression were evaluated by immunohistochemistry. SOD3 effects on cell viability and proliferation, ROS production, and mRNA expression of Hif-1α, Rankl, and Opg in PDL cells and osteoclast differentiation were investigated under normoxia and hypoxia. SOD3 expression …

The Effect Of Crowding On The Accuracy Of 3d Printed Aligners, Tonya Spangler

Theses and Dissertations

Purpose: To evaluate the accuracy of three-dimensionally (3D) printed aligners compared to conventional vacuum-formed thermoplastic aligners with varying levels of dental crowding.

Methods: Digital intraoral scans of 10 different cases were assigned to their respective groups (n=10, each, 30 total) as follows: no crowding (control), moderate crowding, and severe crowding. Using 3Shape software, digital aligner samples were created in standard tessellation language (STL) file format and randomly 3D printed. The same STL files of each case were also sent to a dental laboratory for the fabrication of vacuum-formed samples, which is the current technology used for manufacturing aligners. The intaglio …
