Perguntas Frequentes
What is the importance of sorption and solubility for dental resins?
Sorption (water absorption) and solubility (release of substances) are crucial for the stability and longevity of dental resins. High sorption can lead to expansion, discoloration, and reduced mechanical properties, while high solubility can cause mass loss and release of undesirable components, compromising restoration integrity and biocompatibility. Smart Print Bio Vitality exhibits optimized values for these characteristics.
Which ISO standards are applicable for evaluating sorption and solubility in dental materials?
For the evaluation of sorption and solubility, ABNT NBR ISO 4049:2017 ('Dentistry — Polymer-based restorative materials') and ABNT NBR ISO 10477:2022 ('Dentistry — Polymer-based materials for crowns and veneers') standards are the references. These standards establish the acceptable limits for these parameters, ensuring the safety and effectiveness of materials in clinical use. Smart Print Bio Vitality was tested and approved according to these standards.
How do temperature and immersion time affect sorption and solubility results?
Temperature and immersion time are critical factors in sorption and solubility tests. Elevated temperatures (such as 37°C, simulating the oral environment) and prolonged times (7 days in the test) accelerate water absorption and substance release, providing a more rigorous evaluation of the material's long-term behavior. The test conditions for Smart Print Bio Vitality were standardized to reflect these clinical conditions.
What is the meaning of a negative solubility value, such as -4.44 µg/mm³?
A negative solubility value, such as -4.44 µg/mm³, indicates that the sample gained mass after the immersion and reconditioning cycle, rather than losing it. This can occur due to residual water absorption that was not completely removed during final reconditioning, or the formation of additional cross-links that increase molecular mass. In practical terms, a negative or near-zero value is desirable, as it suggests minimal or no release of components from the material, as observed in Smart Print Bio Vitality.
What equipment is used to perform sorption and solubility tests?
Sorption and solubility tests require precision equipment to ensure the accuracy of the results. In the case of the Afinko report, a Solidsteel Oven, model SSDc 64L, was used for drying and thermal conditioning steps, and a Bel engineering Analytical Balance, model M214Ai, for highly sensitive mass measurements. These equipment are essential to follow ISO standard protocols and obtain reliable data for materials such as Smart Print Bio Vitality.
How do the sorption and solubility results of Smart Print Bio Vitality impact the longevity of restorations?
The low sorption (15.15 µg/mm³) and solubility (-4.44 µg/mm³) values of Smart Print Bio Vitality are indicators of high material stability in the oral environment. This translates into less degradation, lower risk of discoloration, maintenance of mechanical properties, and reduced potential for marginal infiltration over time. Consequently, restorations and prostheses made with this 3D resin tend to exhibit greater longevity and less need for rework, benefiting both the professional and the patient.
Is Smart Print Bio Vitality indicated for use in long-term crowns and veneers?
Yes, Smart Print Bio Vitality is indicated for printing crowns and elements for long-term oral permanence (up to 10 years). Its compliance with ABNT NBR ISO 4049:2017 and ABNT NBR ISO 10477:2022 standards, along with favorable sorption and solubility results, reinforces its suitability for these demanding clinical applications. Furthermore, the resin is biocompatible, a fundamental requirement for long-term devices.
What are the warnings and contraindications for the use of Smart Print Bio Vitality?
Warnings include the need for handling by a specialized professional and the mandatory use of personal protective equipment (gloves and eye protection). The product should not be used for any application other than that reported (long-term crowns and elements), and any use outside the indications and shelf life does not guarantee the specifications. These precautions are standard to ensure safety and efficacy in the clinical environment.
Where can I purchase Smart Print Bio Vitality and other Smart Dent products?
Smart Print Bio Vitality and other Smart Dent products, including dental 3D printers and post-curing stations, can be purchased directly from the official online store: loja.smartdent.com.br. The platform offers access to a complete range of solutions for digital dentistry, with quality assurance and technical support.
Does Smart Print Bio Vitality have toxicological safety certification?
Yes, Smart Print Bio Vitality was subjected to a battery of toxicological safety tests by GROUPE ICARE, an internationally recognized laboratory. The tests included Intra-cutaneous Reactivity, Micronuclei in Ovary Cells, Ames Test, in vivo Pyrogen Test, Skin Sensitization, and Acute Systemic Toxicity. All results indicated that the product is 100% safe, non-toxic, non-mutagenic, non-allergenic, and suitable for contact with skin and tissues, which is fundamental for its clinical application.
