Biomimetic Restoration with Increased VDO: Case study Using Aster Composites and K-Bond Universal + Adhesive System

This article presents a case study by Dr. Victor Garcías of Garcías & Pereira Clínica Dental, focused on the aesthetic and functional rehabilitation of both dental arches using direct adhesive restorations with Aster composites by Kiyomi Dental and the universal adhesive system K-Bond Universal +. The objective was to recover the vertical dimension of occlusion (VDO) and achieve a natural, stable, and biomimetic result. 

Diagnosis and Planning: The Key to Functional Rehabilitation

The treatment began with a diagnostic wax-up in the upper anterior sector (teeth 13 to 23), allowing for the design of an ideal anatomy on both palatal and buccal surfaces. This step was crucial to anticipate the final outcome and establish a slight yet effective gain in vertical dimension, a key factor for the patient’s occlusal and neuromuscular stability. 

Upper Restoration: Enamel and Dentin Bonding with K-Bond Universal +

The first restorative phase focused on rehabilitating the six upper anterior teeth. Aster composites by Kiyomi Dental were used, following a standardized adhesive technique on both enamel and dentin with K-Bond Universal +—a system known for its high adhesion and clinical versatility. 

Following restoration, the patient remained for one week with the new VDO to allow for gradual neuromuscular adaptation before proceeding to the lower arch. 

Lower Restoration: Continuity in Technique and Materials

The next step addressed the eight lower anterior teeth, maintaining the newly established vertical dimension. The same adhesive protocol was followed, ensuring complete isolation and using K-Bond Universal + to maintain consistency in technique and maximize clinical longevity of the restorations. 

This restorative phase left the patient ready for the prosthetic stage, including testing of the planned skeletal framework. 

Layering Technique with Dual-Opacity Composites

To achieve a natural, biomimetic effect, a layering technique with two levels of opacity was applied: 

  • Aster Enamel EA1 (A1) on buccal and palatal surfaces. 
  • Aster Dentin in the central zone, providing optimal chromatic support. 


To preserve the remaining tooth structure, only carious tissue was removed. In grooves or hard-to-reach areas, Aster Flow A2 was used, allowing precise and secure application in narrow spaces. 

Aesthetic Finish: Subtle, Biomimetic Characterization

The final touch was a subtle aesthetic characterization with ochre, white, and blue tints, adding depth, vitality, and individualization to each restoration. 

Conclusion: Predictable and Functional Results Without Complications

Thanks to careful planning, the use of state-of-the-art materials like Aster and K-Bond Universal + by Kiyomi Dental, and a rigorous adhesive technique, Dr. Victor Garcías achieved a comprehensive restoration that not only enhances the patient’s aesthetics but also ensures stable occlusal function and successful neuromuscular adaptation. 

This case study demonstrates how restorative dentistry can deliver natural, long-lasting, and biomimetic outcomes when science, technique, and quality materials come together.
