Background: The aim of this prospective study was to compare root resorption after the leveling phase of treatment, performed by either super-elastic or conventional multi-stranded stainless steel arch wires.
Methods: From a total of 156 future orthodontic patients in a private clinic, 82 were included in the study after excluding those who earlier had orthodontic or endodontic treatment or signs of resorption. Patients were equally arbitrary allocated into two groups, where leveling was performed either with super-elastic heat-activated or conventional multi-stranded stainless steel arch wires.
Purpose: A retrospective evaluation was performed of dentoalveolar and skeletal stability 1 year after mandibular setback surgery using intraoral vertical subcondylar osteotomy (IVSO) combined with intermaxillary fixation.
Patients And Methods: Twenty-eight patients (16 men, 12 women) with skeletal Angle Class III malocclusions were included. Mean age at start of treatment was 23.
Introduction: The purpose of the study was to evaluate impacted maxillary canines as risk factor for orthodontic apical root resorption.
Methods: The sample comprised 66 patients treated with fixed appliances. Thirty-two patients with a unilateral impacted maxillary canine, which was distanced from the roots of the incisors at a preliminary phase of treatment before bonding, formed the impaction group, and 34 patients without impactions served as the controls.
Introduction: The aims of this study were to determine reasons for orthodontic-surgical treatment, to quantify the perceptions of possible improvement 10 to 14 years after treatment, and to assess factors that affect treatment satisfaction and socio-dental impacts on quality of life.
Methods: The participation rate was 36 of 78 patients; their mean age was 45.7 years (SD, 10.
Objective: The aim was to investigate to what extent denture wearers were satisfied with the ambient care (care) received.
Materials And Methods: A study sample of 117 completely edentulous and 56 partially edentulous patients, who had received their dentures in the period 1997-2005 at Bergen School of Dentistry, completed a questionnaire containing eight specific items regarding different aspects of care, each with two positive (a and b) and two negative (c and d) categories, and four global items. The care items, including confidence in the dental team, information, waiting time and cost, constitute the Ambient Care Scale; the global items were concerned with overall care, satisfaction with dentures, self-reported oral and general health.
Dental or skeletal relapse after sagittal split osteotomy advancement surgery? Long-term follow-up.
J Oral Maxillofac Surg
November 2011
Purpose: To evaluate the short- and long-term stability of mandibular advancement surgery with sagittal split osteotomy (SSO), and to investigate when relapse occurs and identify variables contributing to relapse.
Patients And Methods: Thirty-six patients with Class II anomalies were included; the mean age at surgery was 33.0 years.
Purpose: The aim of this study was to compare the clinical performance of metal-ceramic crowns made with an experimental alloy prepared by the Nordic Institute of Dental Materials, containing 15% zirconium and 85% titanium (Ti-15% Zr), and a high noble gold-palladium alloy (Mattikraft).
Materials And Methods: Twenty patients who satisfied the inclusion criteria were selected sequentially from the departmental waiting list. Each patient received 2 crowns in the premolar or molar region.
The purpose of the study was to investigate root lengthening during orthodontic treatment in relation to the age of the patient, the developmental stage of the root, and the anticipated growth. Specifically, the potential benefit of treating young teeth was addressed. The sample consisted of 80 patients with Angle Class II division 1 malocclusions, treated with extraction of at least two maxillary first premolars, and edgewise technique with 0.
