Otimização do tracionamento de canino impactado pela técnica do arco segmentado: relato de caso clinico

Upper canines impaction are considered the second most frequent and are associated to important esthetics and functional limitations. Among the treatment strategies described in the literature the most commonly used are the extraction of the primary canines and the surgical exposure followed by orthodontic traction, that requires an adequate interdisciplinary approach. The aim of this case report is to draw the attention of the clinician to the possibility of adapting the segmented arch technique to manage a canine impaction clinical case.

Tratamento cirúrgico de canino incluso em mento: relato de caso

The mandibular and maxillary canines when well positioned in the arch, are important functionally and aesthetically. Although these teeth are frequently malpositioned in the dental arch, their absence of eruption are not common, occuring more frequently with the maxillary canine than the mandibular canine. The canine transmigration is a well-known pre eruptive phenomenon in which the tooth goes thru the facial midline, occurring more frequently in the mandible than in maxila. Females are more susceptible than males and the right side more than the left one. Normally the patients do not show any symptoms, and this condition is observed during radiographic exams to diagnose the late exfoliation of the deciduous canine or for any other purpose. Due to the relationship between impacted canines and pathologic lesions, infection, trauma to the adjacent teeth, pain, ectopic eruption and interference with prosthesis, it´s indicated the surgical extraction of these teeth. The goal of this article is to describe and discuss the surgical treatment of an impacted canine (43) in the chin.

Prótese metalocerâmica associada à prótese metaloplástica implantossuportada em paciente desdentado total

The use of different methods and materials should be considered during the planning of implant-supported prostheses. Complications such as fractures of the acrylic resin base, wear and fracture of teeth can occur frequently, creating the need for careful planning for each patient, which can make the selection of the type of treatment more complex. Thus, this article describes the oral rehabilitation of a completely edentulous patient with bimaxillary fixed implant-supported prosthesis, with complaints on aesthetics, loss of vertical dimension and fracture of acrylic resin teeth of the upper arch. After the restoration of vertical dimension, his dentures were replaced with new bimaxillary implant-supported fixed prostheses, ceramic and acrylic resin were used as veneering material for maxilla and mandible, respectively. At the end of the treatment, the patient received bimaxillary flat occlusal splints to protect the teeth and implants of possible parafunctional habits. The approach for the treatment allowed a quick and effective resolution, with aesthetic and functional outcomes very favorable for the patient.

Visão contemporânea sobre pinos anatômicos

As an alternative to improve the adaptation of prefabricated posts in flared canals and weakened roots, the option is for relining prefabricated pin, known as a technique of anatomical post. This technique, which can be made with composite resin increases the adjustment post to the walls of the canal and reduces the cementing line, causing the retaining post is less dependent on the mechanical properties of the cementing agent. This article aims to provide an overview of anatomical posts, specifically in the last two decades, based on studies extracted from Scielo, Scopus and Pubmed, referring to the following terms of MeSH Data Base: custom made fiber post, indirect fiber glass posts, root canal therapy and post and core tecnique. According to the literature review in this article, it can be concluded that this technique has been used by several authors and has been shown effective and promising, it creates an individualized retainer with better adaptation and decreased mechanical imbrication cementing line .

Musculoskeletal disorders in upper limbs in dental students: exposure level to risk factors

Aim: This study assessed the risk factors of undergraduate students to develop musculoskeletal disorders (MSD) in the upper limbs, regarding gender, type of dental clinical procedure, mouth region treated, and the four-handed dentistry practice. Methods: Dental students enrolled in the 8th semester in the Araraquara School of Dentistry, UNESP, Brazil, were photographed while practicing 283 dental procedures. The Rapid Upper Limb Assessment (RULA) method was used to evaluate the working postures of each student. The photographs were evaluated and a final risk score was attributed to each analyzed procedure. The prevalence of risk factors of developing MSD was estimated by point and by 95% confidence interval. The association between the risk factor of developing disorders and variables of interest were assessed by the chi-square test with a significance level of 5%. Results: The risk factors of developing MSD were high, regarding most dental procedures performed by the undergraduate students (score 5: 7.07%, CI95%: 4.08- 10.06%; score 6: 62.54%, CI95%: 56.90-68.18%). There was no significant association between the RULA final score and gender (p=0.559), and type of dental procedure (p=0.205), and mouth regions by arch (p=0.110) or hemi-arch (p=0.560), and the use of four-handed dentistry (p=0.366). Conclusions: It can be concluded that gender, type of dental clinical procedure, mouth region treated, and practice of four-handed dentistry did not influence the risk of developing MSD in the upper limbs among the dental students evaluated; however, they are at a high risk of developing such disorders.

Reabilitação estético-funcional sobre implantes agulhados e endósseos

This report shows the resolution of a case study whose aim was promote the aesthetic and functional rehabilitation of upper left hemi-arch over endosseous and needle implant prostheses. To improve the position of the needle implants, we performed the bucco-palatal bending of needles splinting them with composite resin; we removed the screwed implant prosthesis in the regions of the premolars (24 and 25) and molar (26). The mini-abutments of the last two implants were replaced, and in the first premolar and canine, we used cemented abutments due to implant angulation having planned soldering because of implant size and contact with one needle implant that could interfere with intimate contact bone/implant damaging biomechanics. Pick-up impressions were performed with an open tray, using a retractor cord in the needle implants and respective transfer copings. Therefore, models were related on semi-adjustable articulator after a face-bow recording and interocclusal indexes. After working cast fabrication and try-in of infra-structures, these were adjusted and related into the articulator again. Then, after ceramic build-up, adjustments, finishing, and torque, chemically-activated resin cement was applied on units 21 to 24. At the end of the case, we concluded that a good aesthetic and functional rehabilitation depends on thorough knowledge of techniques for each clinical situation.

Conhecimento de mães sobre os procedimentos de emergência nos casos de avulsão dentária

Introduction: Despite tooth avulsion following trauma being relatively common in children, the available studies show that adults have limited knowledge about it. Aim: The purpose of this study was to assess, by a questionnaire, the mothers’ general knowledge about the immediate management of tooth avulsion. Material and method: This descriptive study was carried out on a convenient sample of mothers (n= 65) who participated of the “Pastoral da Criança”, from Araraquara, SP, Brazil. The questionnaire comprised 15 questions about personal data and knowledge on tooth avulsion management. Results: Participants were, on average, 35 years old. A total of 30.8% of the mothers reported that their children suffered dental trauma. The majority had never received advice on this subject (76.9%); and did not know how teeth are kept in the dental arch (69.2%). Almost a half of the sample believed that an avulsed tooth can be replanted (49.2%). In relation to the management of tooth avulsion, 40% of them would clean the avulsed tooth with water, even if it was not dirty (38.5%). Most of them (69.2%) would take the tooth by hand for cleaning purposes, regardless the tooth region; and believed that brushing the tooth was important to take the dirty out (67.7%). Conclusion: The general knowledge of mothers about the immediate management of tooth avulsion was considered inadequate endangering the successful treatment of tooth avulsion.

Gene expression of estrogen receptor-alpha in orbital fibroblasts in Graves’ ophthalmopathy

Graves’ ophthalmopathy (GO) is one of the most severe clinical manifestations of Graves’ disease (GD), and its treatment might involve high-dose glucocorticoid therapy. The higher incidence of GO among females, and the reported association between polymorphisms of estrogen receptor (ER) and GD susceptibility have led us to question the role of estrogen and its receptor in GO pathogenesis. We, thus, assessed estrogen receptor-alpha (ERA) gene expression in cultures of orbital fibroblasts from a patient with GO before (controls) and after treatment with 10 nM and 100 nM dexamethasone (DEX). Orbital fibroblasts showed ERA gene expression. In the cells treated with 10 nM and 100 nM DEX, ERA gene expression was, respectively, 85% higher and 74% lower, than in the control group. We concluded that ERA gene expression is found in the orbital fibroblasts of patient with GO, which may be affected by glucocorticoids in a dose-related manner.

An esthetics rehabilitation with computer-aided design/ computer-aided manufacturing technology

This paper describes a case of a rehabilitation involving Computer Aided Design/Computer Aided Manufacturing (CAD-CAM) system in implant supported and dental supported prostheses using zirconia as framework. The CAD-CAM technology has developed considerably over last few years, becoming a reality in dental practice. Among the widely used systems are the systems based on zirconia which demonstrate important physical and mechanical properties of high strength, adequate fracture toughness, biocompatibility and esthetics, and are indicated for unitary prosthetic restorations and posterior and anterior framework. All the modeling was performed by using CAD-CAM system and prostheses were cemented using resin cement best suited for each situation. The rehabilitation of the maxillary arch using zirconia framework demonstrated satisfactory esthetic and functional results after a 12-month control and revealed no biological and technical complications. This article shows the important of use technology CAD/CAM in the manufacture of dental prosthesis and implant-supported.

Implant rehabilitation in bruxism patient

A white female patient presented to the university clinic to obtain implant retained prostheses. She had an edentulous maxillary jaw and presented three teeth with poor prognosis (33, 34 and 43). The alveolar bone and the surrounding tissues were healthy. The patient did not report any relevant medical history contraindicating routine dental treatment or implant surgery, but self-reported a dental history of asymptomatic nocturnal bruxism. The treatment plan was set and two Branemark protocols supported by six implants in each arch were installed after a 6-month healing period. A soft occlusal splint was made due to the patient's history of bruxism, and the lack of its use by the patient resulted in an acrylic fracture. The prosthesis was repaired and the importance of using the occlusal splint was restated. In the 4-year follow-up no fractures were reported.
