Dental Dimensions In Non-Syndromic Patients With Unilateral Cleft Palate, Blake Boleware
Dental Dimensions In Non-Syndromic Patients With Unilateral Cleft Palate, Blake Boleware
All ETDs from UAB
Objective: The main objective of this study is to determine if any difference in tooth size exists between the maxillary quadrants in non-syndromic patients with unilateral cleft palate using cone beam computed tomography. By understanding the effects of cleft palate on tooth morphology, the multidisciplinary team of specialists involved with the care and treatment of a patient with cleft lip/palate can better understand the intricacies of necessary therapy. This understanding can, in turn, be used for proper planning of desired treatments which can increase the chance of successful achievement of desired outcomes. Materials and Methods: CBCT volumes for 18 patients …
Temporomandibular Joint Function After Orthognathic Surgery, Aikaterini Kleopatra Aslanidou
Temporomandibular Joint Function After Orthognathic Surgery, Aikaterini Kleopatra Aslanidou
All ETDs from UAB
Orthognathic surgery has 3 basic goals: function, esthetics and stability. The relationship between orthognathic surgery and temporomandibular joint function remains highly controversial. Regarding the functional changes and range of mandibular movements after surgery, mandibular hypomobility and other signs and symptoms of joint dysfunction are associated with orthognathic surgery in the literature. The aim of this study is to evaluate the function of the temporomandibular joints at lest 6 months after orthognathic surgery and compare them with non-surgical subjects. The null hypothesis is that there is no difference in subjective symptoms reported by the subjects and clinical evaluation of the range …
Surface Treatment Effects On Shear Bond Strength And Biaxial Flexural Strength Of Three Generations Of Zirconia, Yasko A. Darkoue
Surface Treatment Effects On Shear Bond Strength And Biaxial Flexural Strength Of Three Generations Of Zirconia, Yasko A. Darkoue

SURFACE TREATMENT EFFECTS ON SHEAR BOND STRENGTH AND BIAXIAL FLEXURAL STRENGTH OF THREE GENERATIONS OF ZIRCONIA YASKO A. DARKOUE MASTER OF SCIENCE IN DENTISTRY ABSTRACT Objectives: Mechanical and chemical surface treatments are required to achieve a durable bond to zirconia. The objective of this study is to compare the effects of particle abrasion and pressure on shear bond strength and biaxial flexural strength of Lava (Frame, Plus and Esthetic) zirconia to obtain a favorable combination of pressure and particle type to produce optimum strength and optimize the bond produced. A protocol for mechanical treatment balancing strength of the type zirconia …
Non-Surgical Correction Of Anterior Open Bites Using Temporary Anchorage Devices, Kimberly Spencer Butts
Non-Surgical Correction Of Anterior Open Bites Using Temporary Anchorage Devices, Kimberly Spencer Butts
All ETDs from UAB
Objective: The purpose of this study is to determine the skeletal, dental and soft tissue effects that occur as a result of maxillary posterior TAD intrusion; to compare treatment outcomes of growing patients to a growing matched control group; and to present a simplified TAD intrusion technique. Methods: This is a retrospective cohort study using lateral cephalometric radiographs of 16 (5 male, 11 female, average age 38y 4m) non-growing patients and 16 (5 male, 11 female, average age 13y 11m) growing patients with anterior open bite malocclusions treated with temporary anchorage devices (TADs) to intrude the maxillary posterior segments. Growing …
Smile Outcome Comparison Of Orthodontic Cases Treated With Different Extraction Patterns, Gregory Long
Smile Outcome Comparison Of Orthodontic Cases Treated With Different Extraction Patterns, Gregory Long
All ETDs from UAB
Extraction of premolar teeth for orthodontic purposes is a common treatment approach. The effects of premolar extraction on the occlusion and the face have been studied extensively in the past. To date, however, the effects of premolar extractions on the smile have not been comprehensively quantified in the literature. The purpose of this study was to compare the smile outcome of patients treated with premolar extractions. Methods: This retrospective case-control study established 4 groups of 33 patients each for comparison. Three groups of patients with the same malocclusion were treated with different premolar extraction patterns. The remaining group of patients …
External Root Resorption In The Orthodontic Patients, Frank Earl Litchfield
External Root Resorption In The Orthodontic Patients, Frank Earl Litchfield
All ETDs from UAB
External Apical Root Resorption (EARR) is a side effect of orthodontic treatment that results in root shortening in about one-third of orthodontic patients. Great variability among patients exists in their susceptibility to this multifactorial condition, and both treatment and patient specific factors contribute to EARR. Root resorption values were found to be higher in Hispanics compared to Asians and Caucasians (1). However, the prevalence of EARR is not well documented in all populations. Since African Americans represent the largest minority group in the United States, establishing the prevalence and risk factors for EARR within this ethnicity is important. Objective: To …
