The treatment plan included four first premolars extractions combined with TAD application which used for anteroposterior and vertical anchorage control. The orthodontic treatment was to achieve the effect of counter-clockwise rotation of mandible for the patient who still has remaining growth. After 23 months of orthodontic treatment, Angle Class I molar relationship was achieved. The patient was satisfied with …

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

Taiwanese Journal of Orthodontics

Treatment of anterior open bite presents numerous challenges to the orthodontists. Should an open bite be treated early, or should it be delayed until most growth has been completed is just one of the many questions? Can treatment be done with conventional orthodontics or is a combination of orthodontics and orthognathic surgery indicated? Anterior open bite can develop later in life because of idiopathic condylar resorption, excess mandibular growth, and by iatrogenic causes. This article will discuss both normal and pathological developments and the possible treatment approaches. The importance of understanding the etiology of open bite and address the causes …

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 …
