About this Research Topic
In contemporary dentistry, the success of indirect restorative procedures can be affected by several parameters during lab processing as well as in the dental practice. In the past, assessment of dental materials’ mechanical properties has been used to predict the clinical success of restorative procedures based purely on materials ranking, without considering how the biomaterials behave in the oral environment. Among these properties, flexural strength, tensile strength, hardness, and toughness have been widely evaluated. Currently, these same mechanical properties are still necessary to characterize a new material and to understand how it should be associated with the classical restorative materials. However, antagonist materials, fatigue performance, pH variation and many other variables are included in recent studies which mimic the complex and restoration-unfriendly oral environment.
The correct processing of materials by technicians and dentists can promote adequate bond strength and durable indirect restorations that will resist chewing loads in the long-term. However, errors in the processing of dental materials sometimes occur due to excessive acid etching, surface defects created by diamond burs, high residual stress concentration, incorrect geometry, excessive polymerization shrinkage, and many other factors that can occur and affect the clinical performance of indirect restorative procedures. There is still a lack of information about how clinical and lab parameters can be controlled, how they affect the treatment performance and if different procedures should be performed when using contemporary dental biomaterials. In addition, the usage of digital technologies in the chairside workflow provides new possibilities that still need to be confirmed in the scientific literature. These parameters are of great interest for both technicians and clinicians, considering that such findings can be applied to standardize the empirical choices promoting adequate dental treatments.
This Research Topic will be a collection of papers around, but not limited to, the following themes:
• Assessment of fatigue performance of indirect restorations;
• Comparison between clinical parameters that can reduce the stress concentration generated during the chewing;
• Evaluation of surface treatments protocols to improve the restoration reliability and clinical performance;
• Long-term simulations elucidating the origin of indirect restoration failure and fracture features;
• Description of processing techniques that make it easier to control restoration manufacturing;
• Procedures to improve the restorations surface morphology before and after clinical adjustments.
