3D Printing for Dental Applications.

Due to increased life expectancy and greater concern among populations regarding oral health problems and aesthetics, in the last few years, there has been a growing demand for dental structures and devices to replace/restore missing/damaged teeth [...

Recent Advances on 3D-Printed Zirconia-Based Dental Materials: A Review.

Zirconia-based materials are widely used in dentistry due to their biocompatibility and suitable mechanical and tribological behavior. Although commonly processed by subtractive manufacturing (SM), alternative techniques are being explored to reduce material waste, energy consumption and production time. 3D printing has received increasing interest for this purpose.

Effects of Non-Conventional Sterilisation Methods on PBO-Reinforced PVA Hydrogels for Cartilage Replacement.

Articular cartilage (AC) degradation is a recurrent pathology that affects millions of people worldwide. Polyvinyl alcohol (PVA) hydrogels have been widely explored for AC replacement. However, their mechanical performance is generally inadequate, and these materials need to be reinforced.

PVA-Based Hydrogels Loaded with Diclofenac for Cartilage Replacement.

Polyvinyl alcohol (PVA) hydrogels have been widely studied for cartilage replacement due to their biocompatibility, chemical stability, and ability to be modified such that they approximate natural tissue behavior. Additionally, they may also be used with advantages as local drug delivery systems. However, their properties are not yet the most adequate for such applications.

Development of polycarbonate urethane-based materials with controlled diclofenac release for cartilage replacement.

Hydrogels are very promising human cartilage replacement materials since they are able to mimic its structure and properties. Besides, they can be used as platforms for drug delivery to reduce inflammatory postsurgical reactions. Polycarbonate urethane (PCU) has been used in orthopedic applications due to its long-term biocompatibility and bio-durability.

A State-of-the-Art Review on the Wear of the Occlusal Surfaces of Natural Teeth and Prosthetic Crowns.

This review focuses on the wear mechanisms of natural and restorative dental materials, presenting a comprehensive description and analysis of the works published in the last two decades on the wear at the interface of occlusal surfaces. Different groups of tribological pairs were considered: tooth-tooth, tooth-restorative material (tooth-ceramic, tooth-resin-based-materials, and tooth-metal), and restorative-restorative materials. The lack of standardization of the wear tests impairs the direct comparison of the obtained results.

Additive manufacturing of ceramics for dental applications: A review.

Objective: The main goal of this review is to provide a detailed and comprehensive description of the published work from the past decade regarding AM of ceramic materials with possible applications in dentistry. The main printable materials and most common technologies are also addressed, underlining their advantages and main drawbacks.

Methods: Online databases (Web of knowledge, Science Direct, PubMed) were consulted on this topic.

On the influence of Streptococcus salivarius on the wear response of dental implants: An in vitro study.

This study aims to understand microorganisms' effect and relevance of aseptic conditions on wear performance of dental materials. Tribocouple zirconia/titanium was submitted to tribological tests in the presence of Streptococcus salivarius biofilm, the most abundant bacteria in the oral cavity. Reciprocating ball-on-plate tests were carried out at 37°C, pH 7, 2 N, and 1 Hz, during 2 h, using Ti6Al4V balls as pins and Y-TZP plates.
