Synthetic Elastomeric Chain– A Literature Review, Wan-Tin Lin, Hsin-Chung Cheng, Yung-Kang Shen, Yi-Jyun Chen, Chien-Feng Chen

Taiwanese Journal of Orthodontics

Elastomeric chains were introduced to the orthodontic profession in the 1960s’, and are now an integral part of every day practices. They are used to generate light continuous forces for correcting rotations, consolidating spaces, and retraction canines. They are inexpensive, easily applied, relatively hygienic and require little or no patient cooperation. Elastomeric chain, however, are nor without their disadvantages. When exposed to an oral environment, they absorb water and saliva, permanent stain, and suffer breakdown of internal binds leading to permanent deformation. They also experience rapid loss of force due to stress relaxation, resulting in a gradual loss of effectiveness. …

In the frictionless group, canines were ligated to the mini-screws for indirect anchorage then ASR was done using closing …

Canine Retraction Rate And Angulation With 0.017”X0.025” Versus 0.016”X0.022” Stainless Steel Arch Wire With A Power Arm, Amr R. El-Beialy, Fouad A. El Sharaby, Hend S. Elsayed

Future Dental Journal

Background: The dimensions of the arch wire affect its stiffness and the play between the wire and bracket. Canine retraction over stiffer arch wires limits the degree of canine tipping. However, the greater the wire dimensions, the greater the resistance to sliding. Frictional resistance is known to delay tooth movement. Aim: The aim of this controlled clinical trial was to compare canine retraction rate and angulation with 0.017”X0.025” versus 0.016”X0.022” stainless steel arch wire with a power arm. Materials and Methods: Twenty-four Class II malocclusion patients (age 13.8± 2.6 years) participated in this study. The teeth were leveled and aligned. …

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.

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 …

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 …

Graduate Theses, Dissertations, and Problem Reports

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

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 …
