Three-Dimensional Maxillary Alveolar Ridge Augmentation Using Modified Cortical Shell Technique And Composite Bone Graft, Mostafa Azab, Mohammed Diaa, Waleed El-Beialy, Amr Amin Ghanem

Future Dental Journal

Objective: The present study was performed to assess the 3D alveolar ridge augmentation using the cortical shell from retromolar region and composite bone particulate regarding the width of the residual alveolar ridge. Methods: Thirteen patients with age range 21-40 years old having atrophic anterior maxillary ridge ≤3mm horizontally were included in the study. All patients were subjected to ridge augmentation using composite bone graft and retromolar cortical shell that was fixed in place by two micro-screws. The alveolar ridges were assessed and compared by cone beam computed tomography (CBCT) in the pre-operative, immediate and 4 months post-operative phases by taking …

The Influence Of Cbct-Derived 3d-Printed Models On Endodontic Microsurgical Treatment Planning And Confidence Of The Operator, Shreyas Oza, Johnah C. Galicia

Orthodontics and Endodontics Theses

Aims Use of 3D printed models in Endodontics has been gaining popularity since the technology to create them became more affordable. Currently, there are no studies that evaluate the influence of 3D models on endodontic surgical treatment planning and on operator confidence. Therefore, aims of this study were to: (i) Determine whether the availability of a 3D printed analogue can influence treatment-planning and operator confidence; and, (ii) Assess which factors of operator confidence are influenced, if any.

Materials and Methods Endodontists were asked to analyze a pre-selected CBCT scan of an endodontic surgical case and to answer a questionnaire that …

Comparison Of Shaping Ability Between Continuous Rotary And Manual Instrumentations In Pediatric Endodontics, Burcu Güçyetmez Topal, Seda Falakaloğlu, Hatice Türkoğlu

Journal of Dentistry Indonesia

Objective: The aim of this in vitro study was to evaluate the efficacy of rotary EndoArt Ni-Ti Gold Pedo Kit and K-files in shaping ability, canal transportation, centering ability and instrumentation time in primary molars.

Methods: For the study total of 30 extracted primary molars root with minimum 7mm root length were selected. Shaping of root canals in primary molars were done using the two systems, and CBCT and specialized software were used for scanning and analysis of pre-operative and post-operative to evaluate the groups for their shaping properties, apical transportation and preparation time in primary root canals.

Results: No …

A Cbct Based Evaluation Of Root Proximity Of Maxillary Posterior Teeth To Sinus Floor In A Subset Of Pakistani Population, Momina Motiwala, Aysha Arif, Rabia Ghafoor

Section of Dental-Oral Maxillofacial Surgery

Objective: To evaluate the vertical relationship of the roots of maxillary posterior teeth with maxillary sinus floor, and its association with age, gender and bilateral jaw symmetry.
Methods: The cross-sectional study was conducted at a tertiary care hospital in Karachi from June to December 2018, and comprised patients who visited the dental clinics and underwent cone-beam computed tomography scans. The scans were evaluated in the axial, coronal and sagittal planes and roots were classified using Jungs classification for proximity to maxillary sinus floor. The distance between the sinus floor and the apices of maxillary posterior teeth was measured. Data was …

Accuracy And Reliability Of A Fully Automated Landmark Identification System On Cone Beam Computed Tomography, Ali Ghowsi, David Hatcher, Heeyeon Suh, Joorok Park, Heesoo Oh

Orthodontics and Endodontics Theses

ABSTRACT Introduction: Medical imaging continues to play an increasing role in health care and is an integral part of medicine and dentistry. Recent technological advancements have led to the development of fully automated landmark identification (ALI) systems capable of tracing Cone-Beam Computed Tomography (CBCT). The purpose of this study was to evaluate the accuracy and reliability of an ALI system as a tool for automatic landmark location compared to human judges. Methods: One hundred subjects’ CBCT volumes from multiple imaging centers were traced by two human judges who were calibrated and had an ICC close to 1. Fifty-three landmarks were …

Comparing The Sensitivity And Specificity Of Cbct And Mri In Detecting Osteoarthritis Of The Tmj: A Systematic Review, Gabriel R. Saavedra

Theses and Dissertations

The aim of this systematic review was to compare the sensitivity and specificity of cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI) in detecting osteoarthritis (OA) of the temporomandibular joint (TMJ). This was done by using computed tomography (CT) and the research diagnostic criteria for temporomandibular disorders (RDC/TMD) as reference methods and using CBCT and MRI as index methods. A specific search strategy was developed and applied to these electronic databases: PubMed, Embase, DOSS, and Cochrane. The search results returned 802 articles, which were then narrowed down using the inclusion/exclusion criteria, to four final articles that were included in …

An Airway Analysis Of Patients Diagnosed With Juvenile Idiopathic Arthritis Compared To A Control Group, Matt Gibson

All ETDs from UAB

Introduction: The temporomandibular joint (TMJ) is affected in 30-45%% of Juvenile Idiopathic Arthritis (JIA) patients, with all JIA subtypes at risk for TMJ involvement. JIA patients with TMJ involvement may present with altered craniofacial morphology, including micrognathia, mandibular retrognathia, a hyperdivergent mandibular plane angle, and skeletal anterior open bite. These features are also commonly present and associated with non-JIA pediatric patients with obstructive sleep apnea (OSA). Materials and Methods: The study comprised of a group of 32 JIA patients and a group of 32 healthy control subjects. CBCT images were taken for all patients and were imported into Dolphin Imaging …
