Is Cutaneous Profile Perception An Indicator Of Skeletal Class Iii Malformation Treatment Plan? A Cross-Sectional Study, Ibrahim Hatoum, Rania Nassar

International Arab Journal of Dentistry

Background: The treatment choice in adults with skeletal class III malocclusion represents a challenging task for orthodontists, especially in borderline cases. With the growth spurt being surpassed, the clinician is left between two treatment options: orthodontic camouflage or orthognathic surgery. Around the years, many studies tried to uncover a guide model which enables practitioners to distinguish between skeletal class III that can be appropriately treated by orthodontics alone and those needing surgical intervention.

Aim: The aim of this study is to demonstrate the importance of cutaneous profile perception as a subjective decisive parameter in the treatment of borderline …

Space Maintenance In The Primary And Mixed Dentitions, Giovana Anovazzi Medeiros Dds, Msc, Phd, Chia-En Tsai Dds, James R. Boynton Dds, Ms

The Journal of the Michigan Dental Association

Primary teeth serve many critical functions in the growing child: they allow for proper chewing function for appropriate diet and nutrition, help in speech production and development, promote self-esteem, and importantly preserve space for eruption of the succedaneous permanent dentition. Premature loss of a primary molar can cause a loss of arch perimeter and negatively impact the normal eruption path of premolars. Space maintenance is an approach to minimize or prevent untoward consequences after unavoidable loss of a primary molar. Several types of space maintainers can be used to preserve arch length, including fixed unilateral space maintainers, such as the …

Abstract

Comparison of Skeletal Class III Malocclusion Facial-Shape Subtypes Between

Caucasian, African American, and Hispanic Populations

Rachel K. Huffman, DMD

Introduction: The development of a skeletal Class III malocclusion (Cl III) is complex as it can arise from the overgrowth of the mandible, undergrowth of the maxilla, or a combination of the two. To understand the heterogeneity of this trait clinically, studies have been conducted using facial shape analysis (e.g., Geometric morphometrics (GeoMorph)) of Caucasian and Asian populations to learn more about the principal shapes. Little is known, however, about the predominant principal shape components of Cl III within African …

The Effects Of E-Cigarette Aerosol On The Force Degradation Of Elastomeric Chain: An In Vitro Pilot Study, Nicholas David Palmer

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives

An ideal orthodontic force system should exert continuous light force. An orthodontist has the option to utilize different systems for closing orthodontic extraction space. A commonly used method when closing extraction space is to utilize orthodontic elastomeric chain. Energy Chain® (Rocky Mountain Orthodontics, Franklin, IN) allows for less deformation of shape following the initial stretch, more consistent force, and less force degradation over time. The mouth is a harsh environment that experiences daily changes in pH and temperature. These changes cause elastomeric chain to experience increased force degradation. The creation of the JUUL® (JUUL Labs, San Francisco, …

A Comparison of the Failure Rate of Two Orthodontic Light-Curable Adhesives: A Chart Review

Ian Montgomery Weaver, D.D.S.

Background and Objectives: The overhead costs of running a private orthodontic practice are infamously high, thus there is a notable benefit to finding the most cost effective methods of treating patients while still maintaining high quality care. A relatively new light-cure orthodontic adhesive BracePaste®^® (American Orthodontics™, Sheboygan, WI), introduced to the market in 2017, can fluoresce under UV light to assist in identifying the difference between the enamel of the tooth and the adhesive material itself, an ability which can aid …

The Expression Of Incretin Hormones And Their Receptors In The Submandibular Glands Of Offspring From High Fat Diet-Fed Mother Rats, Pornchanok Sangsuriyothai

Chulalongkorn University Theses and Dissertations (Chula ETD)

Incretins, i.e., glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) promote insulin secretion to reduce postprandial blood sugar. Previous studies found incretins in the salivary glands in rat. However, the role of GLP-1 and GIP in the submandibular gland (SMG) is unclear. This study investigates the effects of a high-fat diet (HFD) on the expression of GLP-1 and GIP throughout the development of rat SMG. Pregnant 11-week-old rats were divided into standard diet and HFD groups (n = 5 each). The newborns were divided into four subgroups (n = 6): standard diet males, HFD males, standard diet females, and HFD …

Effects Of The Cutting Flute Characteristic Of The Orthodontic Miniscrew On Bone Microdamage And Primary Stability, Sansanee Wijarn

Chulalongkorn University Theses and Dissertations (Chula ETD)

Orthodontic miniscrews was developed as an anchorage. Cutting flute geometry of the screw is important for the stability; however, it has not been fully investigated. This study aim to evaluate the effect of cutting flute geometry on cortical bone microdamage and stability. Human bone analogs, 1.0 mm thick, were prepared alongside custom-made Ti6Al4V screws. These screws, with no flutes or modified flute geometries, came in lengths of 1.2, 2.4, and 5.0 mm, each with rake angles of 0° and 20°. Each screw was inserted into a bone sample and removed while measuring the maximum insertion torque and the maximum removal …

Correlation Between Intraoral Markers And The Risk Of Obstructive Sleep Apnea In Children, Linda K. Powers

Designing Of Customized Devices In Orthodontics By Digital Imaging And Cad/Fem Modeling, Kaustubh Mantri, Priyanka Paul Madhu, Gunjan Taori, Nishant Rathi

International Arab Journal of Dentistry

In current decade, patient’s demand of minimal orthodontic treatment have encouraged the introduction of appliance that will be lighter, improved profile and better esthetics with regard to conventional orthodontic treatment. Considering aesthetic treatment options, removable clear aligner treatment got popular among patients since it allows clinician to deliver comprehensive orthodontic treatment while maintaining comfort of patient. The aligners should exert an adequate force in order to shift the tooth to a desirable position. But, in recent times, the relation of applied force and aligner property (eg. thickness) is inadequately witnessed. This article focuses on a patient-focused framework has been formulated …
