“…Higher hardness values are usually correlated with wear resistance [83,99,100]. However, for inhomogeneous materials, selective damage during wear may occur, so the hardness measurements are not sufficient to determine how the material will behave in this respect.…”

Colonization of polymeric dental prosthetic materials by yeast-like fungi and the association of these microorganisms with complications occurring during prosthetic treatment are important clinical problems. In previously presented research, submicron inorganic particles of silver sodium hydrogen zirconium phosphate (S-P) were introduced into poly(methyl methacrylate) (PMMA) denture base material which allowed for obtaining the antimicrobial effect during a 90 day experiment. The aim of the present study was to investigate the flexural strength, impact strength, hardness, wear resistance, sorption, and solubility during three months of storage in distilled water. With increasing S-P concentration after 2 days of conditioning in distilled water, reduced values of flexural strength (107-72 MPa), impact strength (18.4-5.5 MPa) as well as enhanced solubility (0.95-1.49 µg/mm 3 ) were registered, but they were at acceptable levels, and the sorption was stable. Favorable changes included increased hardness , flexural modulus (2.9-3.3 GPa), and decreased volume loss during wear test (2.9-0.2 mm 3 ). The percentage changes of the analyzed properties during the 90 days of storage in distilled water were similar for all materials.

“…Interim dental restorations are used during prosthetic rehabilitation in order to provide function, phonetics and aesthetics to the patient during a short period of the treatment while the final restoration is not finished [1]. The interim restorations can be performed manually using acrylic resin (powder-liquid technique), resin composite or through computer-aided design/computer-aided manufacturing (CAD/CAM) technology [2].…”

Background: This study evaluated the effect of interim restorative materials (acrylic resin (AR), resin composite (RC) or polyetheretherketone (PEEK) for dental computer-aided design/computer-aided manufacturing (CAD/CAM)) on the stress distribution of a posterior three-unit fixed partial denture. Methods: The abutment teeth (first molar and first premolar) were modeled using the BioCAD protocol containing 1.5 mm of axial reduction and converging axial walls. A static structural analysis was performed in the computer-aided engineering software, and the Maximum Principal Stress criterion was used to analyze the prosthesis and the cement layers of both abutment teeth. The materials were considered isotropic, linearly elastic, homogeneous and with bonded contacts. An axial load (600 N) was applied to the occlusal surface of the second premolar. Results: Regardless of the restorative material, the region of the prosthetic connectors showed the highest tensile stress magnitude. The highest stress peak was observed with the use of RC (129 MPa) compared to PEEK and AR. For the cement layers, RC showed the lowest values in the occlusal region (7 MPa) and the highest values for the cervical margin (14 MPa) compared to PEEK (21 and 12 MPa) and AR (21 and 13 MPa). Conclusions: Different interim restorative materials for posterior fixed partial dentures present different biomechanical behavior. The use of resin composite can attenuate the stress magnitude on the cement layer, and the use of acrylic resin can attenuate the stress magnitude on the connector region.

“…Occasionally, temporary treatment has the need to extend through longer periods of time and during this period should provide protection and stability to the pillar teeth. This situation is usually observed when the execution of the fixed prosthesis is associated with some endodontic, orthodontic, periodontal treatment or the installation of implants 26 .…”

Currently, aesthetics, and especially the smile, adds considerable social value. In this way, patients suffering from dental loss wish that their rehabilitation be performed quickly and safely. The aim of oral rehabilitation is to restore masticatory, phonetic, aesthetic and quality of life to the patient. The diagnostic step is one of the most important and relevant steps in establishing a correct treatment plan and, in this way, it is possible to obtain excellent results. The present study aimed to demonstrate the importance of diagnostic waxing in oral rehabilitation. Patient sought treatment at the Dental Prosthesis Specialization Course at Odonto School, due to complaints associated with aesthetics and function. To improve their quality of life, planning of case was carried out through diagnostic waxing and a prosthetic solution was proposed. At the end of treatment and during the follow-up of the case, the patient reported satisfaction and significant improvement in quality of life. It can be concluded that the diagnostic waxing presents customized solutions offering, through a previous study, an effective clinical resolution to the patient. Keywords: Mouth Rehabilitation. Dental Restoration, Temporary. Dental Restoration, Temporary. Resumo Atualmente, a estética, e em especial o sorriso, agregam um valor social considerável. Dessa forma, ao sofrerem a perda dental, os pacientes desejam que sua reabilitação seja realizada de forma rápida e segura. A reabilitação oral tem como objetivo devolver ao paciente a eficiência mastigatória, fonética, estética e a qualidade de vida. A etapa diagnóstica constitui um dos passos mais importantes e relevantes no estabelecimento de um correto planejamento do tratamento e, desta forma, torna-se possível obter resultados de excelência. O presente estudo teve como objetivo demonstrar a importância do enceramento diagnóstico na reabilitação oral. Paciente procurou tratamento no Curso de Especialização em Prótese Dentária da Odonto School, devido a queixas associadas a estética e função. Para melhorar sua qualidade de vida, foi realizado o planejamento do caso por meio do enceramento diagnóstico e uma solução protética foi proposta. Ao final do tratamento e durante o acompanhamento do caso, a paciente relatou satisfação e melhora significativa na qualidade de vida. Pode-se concluir que o enceramento diagnóstico apresenta soluções personalizadas oferecendo, por meio de estudo prévio, uma resolução clínica efetiva ao paciente. Palavras-chave: Reabilitação Bucal.
