External tooth bleaching demands knowledge and technology fully mastered by trained and highly professional dental surgeons. It is paid work that starts with detailed explanation and awareness by the patient regarding responsibilities assumed, time spent and operational costs. At-home tooth bleaching was once part of the historical evolution of the technique, but current knowledge and technology allows ruling it out from the protocols offered to patients. At-home tooth bleaching causes...
Current Restorative Dentistry is adhesive, esthetic and conservative. Which of these characteristics comes first is what has been creating various interpretations.
World Dentistry has been going through a very worrying moment regarding over-indication of ceramic dental restorations. In an article published in 2011, the author denounced unrestricted use of ceramic restorations in favor of a created dental esthetic1. In order to reach such result, a lot of tooth preparation was required, besides endodontic treatments and the use of intra-radicular retainers, with no other purpose but allowing cementation of ceramic pieces. Similarly, the technique of...
Esthetic complications involving implants are hard to be corrected and require multiple procedures, whose result depends, essentially, on the initial condition of the defect. In short, two scenarios are possible: implant maintenance or implant removal. In both situations, surgeries will be necessary for esthetic improvement of the peri-implant tissues, especially in the transition zone.
Introduction: Minimally invasive dentistry allows aesthetic transformation of the smile in a fast and predictable way, since it is sustained by the basic concepts of biology, function and aesthetics. The preservation of the enamel structure is fundamental for the long-term restoration stability. For this, the preparation strategy must be defined, guaranteeing the minimum removal of the tooth structure giving ideal working conditions for the dental technician (ceramist) who makes the ultra-thin...
Abstract: Rehabilitation of a single upper central incisor is considered an esthetic challenge for the dental team. In addition, it produces anxiety in the patient, for being an esthetic region. The present article reports a case in which a reintervention was necessary on an upper central incisor, due to mobility of the crown, related to fracture of the intraradicular retainer. Removal of crown and existing intraradicular retainer was necessary, followed by endodontic retreatment, placement...
Abstract: The demand for aesthetic dental treatments is increasing. The aim of this paper is to present a case report and discuss the treatment performed to solve the problem of color alteration in teeth with deep, opaque and well defined spots. It can be concluded that tooth bleaching, followed by mechanical removal of the opaque areas and restoration with composite resin, by the stratified technique, was a conduct with immediate resoluteness for solving the complaints of the patient and...
Abstract: The aim of this study was to evaluate the shear bond strength of a dual- cure resin cement (Panavia F, Kuraray) to two zirconia ceramics (Lava, 3M ESPE and Katana, Kuraray Noritake) with prior application a coupling agent (Z-Prime Plus, Bisco or Monobond Plus, Ivoclar Vivadent), argon plasma or a combination of coupling agent and plasma. Zirconia plates with 13-mm length, 5-mm width, and 1-mm thickness approximately were used. The zirconia surfaces were abraded with Al2O3 sandpaper...
Introduction: In modern society and contemporary Dentistry, the search for proper function and good aesthetics is predominant. In order to achieve increasingly beautiful, harmonic and natural results, the development of indirect material used in oral rehabilitation is constant. Examples of indirect material widely used are pure ceramic crowns (metal-free) and highly aesthetic-content systems, such as IPS e.max. However, unexpected events, such as root fracture, remain unpredictable in daily...
Abstract: Dental implants are widely recognized as a viable treatment for patients with totally edentulous jaw and/or maxilla. Implant-supported fixed prostheses are an predictable treatment option with proven durability, when their infrastructure is adapted and feature passivity to the implant/abutment system. The preparation of these infrastructures can be performed using the lost wax technique or by the digital scanning and milling system known as CAD/CAM. On these infrastructures various...
Introduction: The use of physical barriers to isolate cells with regenerating interest and prevent the penetration of cells inappropriate to the repair has been demonstrated over the past few decades. The use of membranes on bone reconstructions has important benefits. The barrier membranes can be non-absorbable or absorbable, which have collagen of bovine and swine as the most used material in its structure. Objective: The objective of this work is to present through a literature review the...
