A Comparison Of Orthodontic Intraoral Scan Results Between Staff And Volunteers, Andrew Lee

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: This pilot study is the first to assess and compare a trained staff’s intraoral scan to a clinical examination by comparing the overbite, overjet, Angle canine and molar classification, and gingival health. The second part of this study is to determine if the self-scan scan from a patient is as reliable to the staff’s scan. Introduction: Orthodontic treatment is usually provided over a sequence of appointments. During each appointment, the doctor clinically evaluates the patient, analyzes the progress and provides adjustments to continue with the treatment. The most common clinical criteria evaluated are overbite, overjet, upper and lower midlines, …

Comparison Of Digital Treatment Setups And Final Treatment Outcomes Of Class Ii Division 1 Malocclusions Treated With Premolar Extractions, Sogol Shantiyai

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: This study aimed to determine whether there are differences between pre-orthodontic treatment dimensions when compared to the virtual treatment simulations and actual orthodontic treatment outcomes in Class II malocclusions treated with two or four premolar extractions.

Introduction: The use of intraoral scanners has become commonplace in orthodontic practices, giving practitioners the ability to scan and assess maxillary and mandibular dental morphology and occlusal relationships chairside and in real-time. Practitioners can use virtual treatment planning to evaluate different extraction patterns, visualize potential non-extraction outcomes using interproximal reduction, and alter anchorage strategies based on the amount of retraction or protraction required …

A Comparison Of Lateral Cephalometric And Arch Dimension Changes In Patients With Class Ii Malocclusions Treated With 2-Premolar And 4-Premolar Extraction Patterns, Melissa Marie Ven Dange

UNLV Theses, Dissertations, Professional Papers, and Capstones

The aim of this study is to gather and analyze data representing detailed changes in model and cephalometric variables that will support clinicians in the premolar extraction decision- making process during camouflage treatment of class II dental patients. It is expected that the models, as measured by intra-arch dimensions, overjet, overbite, and mandibular crowding, and cephalometric radiographs, evaluated by their anteroposterior skeletal discrepancy, incisor inclinations, dental and skeletal vertical positions, and soft tissue characteristics, will significantly differ from within the same treatment group, pre-treatment to post-treatment, and between treatment groups. This retrospective study evaluated the model and cephalometric changes in …

Comparison Of Heat Generated During Twist Drilling Protocol By Guided And Non-Guided Implant Surgery, Joshua Lee

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Guided implant surgery is becoming more prevalent among clinicians and is crucial for cases in which there are concerns about the proximity of the implant to vital anatomical structures, esthetic concerns, and the amount/quality of bone available. Surgical guides help with the angulation and positioning of the implant through the use of a CBCT scan and digital intraoral impression. However, there are some drawbacks with guided surgery. Heat that is generated during the osteotomy is one of the issues that has been of concern. The guide acts as a shield against the water irrigation from reaching the osteotomy …

A Comparison Of Heat Generated Between Carbide And Diamond Bur During Implantoplasty, Bryce Chun

Loma Linda University Electronic Theses, Dissertations & Projects

Purpose: This study was conducted to evaluate heat generated during the implantoplasty procedure by comparing the heat generated using either a carbide or diamond round bur.

Biomedical Applications Of Tio2 Nanostructures: Recent Advances, Sevda Jafari, Baharak Mahyad, Hadi Hashemzadeh, Sajjad Janfaza, Tooba Gholikhani, Lobat Tayebi

School of Dentistry Faculty Research and Publications

Titanium dioxide (TiO₂) nanostructures are one of the most plentiful compounds that have emerged in various fields of technology such as medicine, energy and biosensing. Various TiO₂ nanostructures (nanotubes [NTs] and nanowires) have been employed in photoelectrochemical (PEC) biosensing applications, greatly enhancing the detection of targets. TiO₂ nanostructures, used as reinforced material or coatings for the bare surface of titanium implants, are excellent additive materials to compensate titanium implants deficiencies—like poor surface interaction with surrounding tissues—by providing nanoporous surfaces and hierarchical structures. These nanostructures can also be loaded by diversified drugs—like osteoporosis drugs, anticancer and antibiotics—and …

Analysis Of Palatal And Upper Airway Dimensions In Patients With Excessive Daytime Sleepiness: A Retrospective Cone-Beam Computed Tomography Study, Daniel Jarrett

UNLV Theses, Dissertations, Professional Papers, and Capstones

Excessive Daytime Sleepiness (EDS) is the measure of ones propensity to fall asleep during normal daily activities. It has been reported in 20%-50% of adults in the United States and is the most frequent symptom of patients presenting to sleep clinics. EDS is the result of both primary hypersomnias such as narcolepsy and idiopathic hypersomnia and, more commonly, secondary hypersomnias such as sleep deprivation, psychiatric conditions, medications, illegal substances, and obstructive sleep apnea (OSA).

The etiology of OSA is multifactorial. Collapsibility of the upper airway is influenced by both neuromuscular tone and craniofacial anatomy. Common predisposing factors for small airways …

Clinically Relevant 3d Characterization Of Simulated Non-Carious Cervical Dental Lesions And The Effects Of Toothbrush And Toothpaste Types On Wear, James Needy

Biomedical Engineering Undergraduate Honors Theses

This study sought to develop a novel method to quantitatively characterize non-carious cervical lesions (NCCLs) using an intraoral scanner (IOS) paired with Geomagic Wrap mesh software. The goal was to compare results with those obtained using an optical profilometer and Proscan superimposition software for clinical application. Comparisons were made using a previously published dataset aimed at measuring tooth loss associated with differing toothbrush and toothpaste types. Results show good comparability between methods and confirm that variation in brush stiffness and paste abrasivity result in significantly and predictably different levels of NCCL development. Extracted human maxillary premolars were assigned to one …

Differential Diagnosis And Histopathological Analysis Of Localized Gingival Overgrowths: Study Of 218 Cases From Northeast Thailand, Lordjie Marr Morilla, Ajiravudh Subarnbhesaj, Poramaporn Klanrit

Journal of Dentistry Indonesia

Localized gingival overgrowths (LGOs) are relatively common clinical findings. These lesions can be associated with chronic irritation, infections, or they can represent benign or malignant tumors that can either be primary or metastatic. The etiology of these lesions is multifactorial, but the most prevalent cause is reactive hyperplasia and inflammation induced by dental plaque. Objective: This study presents the prevalence of LGOs in Northeast Thailand and identifies the most common LGOs in the region. Methods: A series of 218 LGO cases was studied. Results: Pyogenic granuloma (PG), gingival squamous cell carcinoma (GSCC), and peripheral ossifying fibroma (POF) were the three …

Management Of Atypical Symmetrical Ankylosis Of Maxillary Deciduous First Molars With Permanent Successors: A Single Case Report, Kemal Gulduren, Aylin İslam

Journal of Dentistry Indonesia

Dentoalveolar ankylosis is the union between the tooth root and the dentoalveolar bone. Clinically, the affected tooth is unsuccessful to erupt, exhibits an infraocclusal position within the dentoalveolar arch, elicits a metallic sound on percussion, and has reduced or absent mobility. Objective: This single case report illustrates the management of idiopathically ankylosed maxillary deciduous first molars. Case report: The patient was a 6-year-old female with maxillary deciduous first molars in infraocclusal position due to idiopathic ankylosis. The ankylosed deciduous teeth were monitored regularly. After a 27-month follow-up, the infraocclusion became severe. No vertical deficiencies in other alveolar regions were detected. …
