Dentistry And The Law: Dealing With Patients Who Have Been Using Marijuana, Dan Schulte Jd

The Journal of the Michigan Dental Association

When dealing with patients who emit a strong marijuana odor, it's crucial to focus on their capacity to provide informed consent and the ability to deliver treatment up to the standard of care. Judging their level of intoxication solely by appearance and smell can be unreliable, so it's best to avoid making such judgments. Instead, inform patients that you may refuse treatment if their odor or other factors hinder your ability to provide care. To prevent last-minute issues, communicate this policy in advance, particularly to patients with a history of marijuana odor. Dismissing such patients from your practice may also …

Assessment Of Skeletal Changes And Mandibular Plane In Growing Patients Treated With Miniscrew Assisted (Marpe) And Conventional Rapid Palatal Expansion Using Cbct Images, Daniel Voorhees, Jonas Bianchi, Heesoo Oh

Orthodontics and Endodontics Theses

Background: Maxillary expansion has long been used in children and adolescents for transverse discrepancies and dental crowding. With age, the mid-palatal suture becomes increasingly mature, requiring heavy, rapid force in order to achieve skeletal expansion. As an individual grows into adulthood, it has been demonstrated that a skeletally anchored expander can be used in order to achieve successful sutural separation. The side effects between these two types of expanders, including dental tipping with relative extrusion of buccal segments and clockwise mandibular rotation, have been demonstrated to have differences in their degrees of severity. However, most of the studies have evaluated …

The treatment of multiple impacted anterior teeth is challenging. Proper treatment plan, meticulous biomechanics design and close collaboration with interdisciplinary team work are key factors to achieve better esthetic and periodontal outcomes. For impacted tooth cases, CBCT images can provide more detailed information about the location of the impacted tooth and its surrounding periodontal conditions during treatment. This case report described the treatment of a mild skeletal Class III, facial asymmetry teenager with dilacerated impacted maxillary left central incisor. Because of the unpredictable prognosis of dilacerated impacted central incisor, our treatment goal was to forced erupt the deeply horizontal impacted …

Correction Of Extruded Upper First Molars And Bimaxillary Protrusion By Temporary Anchorage Device, Ignatia Wulandari, Retno Widayati

Taiwanese Journal of Orthodontics

Early loss of the lower first molar may cause extrusion of the upper first molar and mesial tipping of the lower second molar. It could be locked by the mesial contour of the upper second molar, causing the door-wedge effect which impedes the intrusion of the upper first molar. Skeletal Class II malocclusion, canting, and the need for anterior retraction on the upper arch was adding space requirement and anchorage problem to the case. Treatment by using absolute anchorage would be the most efficient way to treat this case. This case report aims to show how to manage molar extrusion, …

Mandibular Expansion Appliances And Their Activation Protocols, Tivanani Venkata Durga Mahendra, Vyshnavi Mulakala, Manda Anoosha

Taiwanese Journal of Orthodontics

A tooth size-arch length discrepancy (TSALD) occurs when there is an imbalance between the size of the teeth and the space available in the dental arches to accommodate them. Relief of crowding through expanding the arch is the most employed non-extraction method in orthodontics. Because of the absence of a midline suture and the resistance of the mandibular body, resolving crowding in the lower arch is more complex than in the upper arch. However, numerous researchers have devised innovative techniques and methods to successfully bring about the desired and stable changes through mandibular expansion. The advantage of this procedure was …

Factors Affecting Mandibular Growth And Displacement And Their Effect On Treatment Outcome, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

Orthodontists often have difficulty distinguishing between growth and displacement when it comes to the mandible and often the two are merged into one and referred to as just mandibular growth. It is clinically important to distinguish between the two as it can greatly affect the choice of treatment protocol and mechanics. In this review we shall attempt to clarify the issue with clinical examples in the hope of bringing more understanding to the problem. Controlling the factors that are involved in determining the outcome of orthodontic treatment in a growing patient can often be a difficult task and is affected …
