The objective of this work was to assess the knowledge about orthodontic tooth movement and dental trauma held by a group orthodontists in specific areas Brazil. For purpose, 166 questionnaires with 15 questions subject were distributed. One hundred five properly filled collected after 30 days. It concluded that, except for avulsion, on injuries professionals interviewed considered unsatisfactory, 40% them not acquainted recommendations traumatized teeth.

Abstract Objective This study evaluates the bond strength of two compositions aesthetic translucent zirconia (TZ). Materials and Methods For this evaluation, test specimens were prepared from ICE Zirkon TZ Prettau Anterior (PAZ) that stored in distilled water at 37°C for time periods: T1 (24 h) T2 (90 days) to simulate aging. Two factors evaluated samples—ceramic aging time. The samples subjected tests microshear fracture type using scanning electron microscopy. Results results analyzed...

ABSTRACT Objective: The objective of this study was to clinically and radiographically assess the peri-implant conditions implants used as orthodontic anchorage. Methods: Two groups were studied: 1) a test group in which osseointegrated anchorage, with application 200-cN force; 2) control not subjected force, but supported screw-retained prosthesis. Clinical evaluations performed three, six nine months after prosthesis installation 1- 3-year follow-up examinations. Intraoral periapical...

The aim of this study was to evaluate the occurence compensation in mesiodistal axial inclinations canines skeletal malocclusions patients. sample consisted 25 Angle Class II, division 1 malocclusion (group 1) and 19 III patients 2). After measurement dental angulations through a method that associates plaster model photography AutoCad software, comparisons between groups were performed by T-test for independent samples. Results showed there no statistically significant difference (p < 0.05)...

OBJECTIVE: The objective of this study was to assess the histological alterations that occurred in periodontal area rat molars submitted induced tooth movement (ITM) right after an intentional trauma (subluxation). METHODS: Forty adult male Wistar rats (Rattus norvegicus albinus) were selected. animals divided into eight groups (n = 5), according combination variables: Group 1 - control (neither nor ITM); 2 ITM; Groups 3, 4, 5 and 6 dentoalveolar corresponding, respectively, 1, 8 10 days...

Abstract Objective To evaluate and compare the friction of different ligature modes used in orthodontics, to propose a new model for conventional brackets (“H low-friction orthodontic ligature). Materials Methods Samples were randomly divided into seven experimental groups: (1) resin H (H3D), designed by authors this study produced 3D printer, with bracket; (2) metal (HFM), (3) passive self-ligating bracket (SLP); (4) “8” unconventional elastic (LT8), (5) loose (MLS), (6) fully tightened...

Aims: The objective of this study was to evaluate the effects ovariectomy on histological structure periodontal tissues and extent root resorption during orthodontic tooth movement in rats. Study Design: This an experimental research study. Methodology: A total 24 rats Wistar were divided into four groups: Group 1 (CTL) - 6 with no procedure; 2 (ITM) subjected induced for 7 days; 3 (OVX) that underwent ovariectomy; 4 (OVX +ITM) both days. After period, animals euthanized, jaws removed, fixed...

The success of tooth movement in treating traumatized teeth depends on the severity initial injury. objective this study was to evaluate histological structure periodontal tissues and root resorption during orthodontic teeth. A total 24 female Wistar rats were used divided into four experimental groups: Group 1, 6 that not subjected any procedure (control); 2, induced (ITM); 3, underwent dentoalveolar trauma (DT); 4, DT+ITM. At end period, animals euthanized, maxilla removed processed for...

As más oclusões são definidas como alterações esqueléticas e/ou dentárias que podem ser desenvolvidas devido a fatores genéticos ou ambientais. Essas classificadas de acordo com o crescimento vertical em mesofacial, braquifacial e dolicofacial, e, sagital Classe I, II III Angle. conformações esqueléticas, interferem diretamente na posição da articulação temporomandibular (ATM), fossa condilar por isso, existem relatos as pode uma das causas disfunção (DTM). A DTM envolve dor craniofacial,...

Abstract Vitamin D (VD) is important for the development and maintenance of bone tissue. This study used clinical radiographic evaluations to analyze whether insufficient VD levels affect periimplant health patients with implant-supported prostheses. Data were collected 33 prostheses: probing depth (PD); width keratinized mucosa (wKM); bleeding index (mBI); plaque (mPI); distance from implant crest level using chemiluminescence. After 1 year prosthesis installation, under 30 ng/ml at...
