Cone-Beam Computed Tomography (CBCT) has been introduced in 1998. This radiological imaging procedure has been provided for dentistry and is comparable to computed tomography (CT) in medicine. It is expected that CBCT will have the same success in dental diagnostic imaging as computed tomography had in medicine. Just as CT is responsible for a sign...

Background: Social media are one of the most common and easily accessible ways of gaining information about orthodontic treatment. Objective: The main objective of this study was to systematically search the literature and determine the various aspects of the interrelationship between social media and orthodontics from the patient's perspective....

Introduction: Our aim was to evaluate the risk of external apical root resorption (EARR) in mesialized mandibular molars due to space closure in patients with unilateral second premolar agenesis. The contralateral side served as the control. Methods: After application of eligibility criteria, 25 retrospectively selected subjects (median age, 14....

OBJECTIVES:To test the applicability, accuracy, precision, and reproducibility of various 3D superimposition techniques for radiographic data, transformed to triangulated surface data. METHODS:Five superimposition techniques (3P: three-point registration; AC: anterior cranial base; AC + F: anterior cranial base + foramen magnum; BZ: both zygomatic...

Summary INTRODUCTION : The cervical vertebrae maturation (CVM) method is used to determine the timing of treatment of Class II malocclusion. Because its performance has not been tested in patients with Class II, the objective of this study was to evaluate the effectiveness of the CVM method in predicting growth peak in Class II malocclusion. Twenty...

Le collage d’un fil torsade souple sur les faces linguales des six dents anterieures mandibulaires est une modalite de contention couramment utilisee. Les complications sont rares mais peuvent etre assez serieuses pour provoquer des degâts biologiques. Cet article presente une complication serieuse d’un fil de contention torsade souple, colle en li...

Cone beam computed tomography (CBCT) is frequently used in treatment planning for alveolar bone grafting (ABG) and orthognathic surgery in patients with cleft lip and palate (CLP). CBCT images may depict coincident findings. The aim of this study was to assess the prevalence of incidental findings on CBCT scans in CLP patients. Initial CBCTs taken...

Objective: To assess objectively patient compliance with removable orthodontic appliances and the effect of possible influential factors. Materials and methods: Wearing times of 45 White patients were recorded with the aid of the TheraMon microsensor. Patient compliance was assessed relative to wear prescription and other parameters, such as age...

Introduction: The purpose of this study was to examine the overall success of miniscrews inserted in the paramedian palatal region for support of various appliances during orthodontic treatment. Methods: The patients received 1 or 2 miniscrews in the paramedian anterior palate of 8.0-mm length and 1.6-mm diameter placed during orthodontic treatm...

Die Befestigung eines Kleberetainers an den Lingualflächen aller sechs unterer Frontzähne stellt eine übliche Maßnahme zur Langzeitretention dar. Komplikationen sind dabei zwar selten, sie können aber schwerwiegend genug sein, um biologische Schäden zu verursachen. Der vorliegende Beitrag stellt eine schwere Komplikation im Zusammenhang mit einem K...

Cleft palate is a common birth defect in humans. Elevation and fusion of paired palatal shelves are coordinated by growth and transcription factors, and mutations in these can cause malformations. Among the effector genes for growth factor signaling are extracellular matrix (ECM) glycoproteins. These provide substrates for cell adhesion (e.g., fibr...

Bonding a flexible spiral wire retainer to the lingual surfaces of all six anterior mandibular teeth is a commonly used type of retention. Complications are rare but can be serious enough to produce biologic damage. This article presents a serious complication of a lingual flexible spiral wire retainer. Four years after the orthodontic treatment, a...

To evaluate dental arch relationship in preschoolers with unilateral cleft lip and palate after early alveolar bone grafting (ABG). Three raters blindly assessed the dental arch relationship with the GOSLON Yardstick (using a 5-point scale, from 1--very good to 5--very poor outcome) in Early-grafted group (27 boys and 15 girls; mean age = 5.2 years...

Digitale Volumentomografen (DVT), die speziell für den zahnärztlichen Gebrauch entwickelt wurden, haben Einzug in die Kieferorthopädie gehalten. Sie bieten echte 3D-Bildgebung mit kleinerer Strahlenbelastung und geringeren Kosten als die konventionelle Computertomografie. In diesem Übersichtsartikel werden einige wichtige Aspekte dieser Technologie...

To determine the frequency of incidental maxillary sinus findings using cone-beam computed tomography (CBCT) images made for orthodontic purposes. One hundred thirty-nine consecutive CBCTs from 134 patients treated at the Department of Orthodontics and Dentofacial Orthopedics, University of Bern, Bern, Switzerland. Indications for CBCT imaging incl...

To determine (1) the optimal sites for mini-implant placement in the maxilla and the mandible based on dimensional mapping of the interradicular spaces and cortical bone thickness and (2) The effect of age and sex on the studied anatomic measurements. The cone beam computed tomography images of 100 patients (46 males, 54 females) divided into two a...

Numerous efforts have been made towards three-dimensional (3D) radiographic imaging in all fields of dentistry, ranging from oral surgery to orthodontics. Although computerized tomography (CT) has been available for quite some time now, its use in dentistry has always been limited because of cost, access, and dose considerations. In orthodontics, d...

The aim of the study was to report on oral, dental and prosthetic conditions as well as therapeutic measures for temporarily institutionalized geriatric patients. The patients were referred to the dentist since dental problems were observed by the physicians or reported by the patients themselves. This resulted in a selection among the geriatric pa...

To analyze computer-assisted diagnostics and virtual implant planning and to evaluate the indication for template-guided flapless surgery and immediate loading in the rehabilitation of the edentulous maxilla. Forty patients with an edentulous maxilla were selected for this study. The three-dimensional analysis and virtual implant planning was perfo...

To assess the effects of the highly reactive molecule of ozone on sound enamel physical properties and its effects on sealing ability. The effect of ozone on sealant tag length, microleakage and unfilled area proportion were evaluated on intact and prepared sound molar fissures. Microhardness, contact angle and acid resistance tests were performed...
