🔬 Research and Development: The Beginning of a Scientific Revolution

Smart Dent is the company behind the Smart Print Bio Vitality 3D Resin, which is the result of more than three years of international research among universities in South Korea, the United States, and France, with over 100 formulations tested before reaching the Brazilian market. The result is a 3D resin that combines advanced engineering, nanotechnology, and proven biocompatibility, developed especially for high-performance dental 3D printing. It is the only long-lasting resin in Brazil that is manufactured in Brazil and the USA, and that has proven clinical cases with over 5 years.

⚗️ ANP Nanotechnology: Unparalleled Mechanical and Aesthetic Performance

The secret of Vitality lies in its ANP nano-hybrid (Advanced Nanosilicate Particles) formulation.

• This technology uses inorganic silica particles between $0.7 \mu m$ and $5 nm$, distributed in a controlled manner, ensuring strength, superior polish, and natural finish.
• The intelligent combination of spherical and amorphous particles improves mechanical and aesthetic performance, offering a structure comparable to that of natural dentin.
• The filler content is greater than 58 wt% (ANP), which contributes to better polish and abrasion resistance.
• The organic matrix is stable, composed of high-purity monomers and oligomers, which ensure chemical resistance, thermal stability, and total biological safety.

💡 Optimized Photopolymerization System for Production

Vitality uses a highly efficient photoinitiator system, designed to react perfectly to the wavelength of dental 3D printers.

• This ensures complete curing, without residual monomers, resulting in mechanically and chemically stable parts.
• The high monomer conversion rate and adjustable curing speed make Vitality a reliable and practical 3D resin for daily clinical use.

🧫 Proven Biocompatibility (ISO 10993): Safety First

The safety of Vitality has been validated by rigorous toxicological tests conducted under Good Laboratory Practices (GLP) and ISO 10993 compliance, carried out by ICARE/MEDLAB laboratories (France and Switzerland).

Approved Toxicological Tests (According to ISO 10993)

The tests below ensure that the material is completely safe for intraoral use, with international recognition by bodies such as the FDA (USA) and ANSM (France).

• Pyrogen Test (In Vivo Pyrogenicity): Approved. Confirms that the material does not contain pyrogens, not causing febrile reactions or immediate adverse systemic inflammation when used in contact with the body.
• Skin Sensitization: Approved. Product considered NON-SENSITIZING, with low risk of causing allergic or hypersensitivity reactions when coming into contact with the patient's tissues and mucous membranes.
• Acute Systemic Toxicity: Approved. No toxic effects detected under the tested conditions.
• Mammalian Micronucleus and Ames Test (Mutagenicity): Approved. Confirms that the material has no mutagenic potential, being safe for long-term clinical use.
• Intracutaneous Reactivity: Approved. Concluded that the product DOES NOT PRESENT MUTAGENIC POTENTIAL, which reinforces its suitability for the manufacture of permanent dental devices.

⚙️ Certified Mechanical Performance (ISO 4049:2019)

The ANP Nano-Hybrid formulation meets and exceeds the critical criteria of the ISO 4049 standard for definitive restorative materials (Type 1). Smart Print Bio Vitality offers mechanical performance comparable to premium CAD/CAM 3D resins.

In comparative tests, Vitality showed up to four times less wear than ceramic blocks like Grandio Blocs (Voco GmbH).

✨ Radiopacity and Aesthetic Stability

Diagnostic Visibility (Radiopacity)

The radiopacity of Smart Print Bio Vitality is $1.048 mm Al$.

• This value places the material at the same level of visibility as human dentin ($1.058 mm Al$).
• The material is sufficiently radiopaque to be distinguished from caries and failures, which ensures optimal diagnostic visibility.

Proven Aesthetic Stability (ABNT NBR ISO 4049)

Color Stability (Shade A) was evaluated under different accelerated aging conditions (thermal, humid, and radiation).

• In all tests, the test specimens maintained the A2 coloration.
• The result suggests excellent photochemical and thermal resistance of the evaluated polymeric material, meeting the criteria of ABNT NBR ISO 4049:2017 and ISO 10477:2004 standards.
