Monolithic and polychromatic: VITABLOCS are the latest trend

Monolithic restorations from blanks with an integrated shade gradient are becoming more and more popular. It's no wonder: these blocks and discs make life far easier for users as they fundamentally replicate the natural shade effect of dentition. This saves time and streamlines workflows. Users can focus more on morphology and texture, and even in the anterior region, create patient appropriate restorations with little or no characterization. For the patient, the veneer-free restoration means a reduced risk of chipping or fracture.

Proven and ahead of its time

The proven feldspar ceramic VITABLOCS TriLuxe forte with a shade transition from the cervical area to the incisal edge has already been aligned with this current trend since 2007. Just three years later, VITABLOCS RealLife completed the polychromatic VITABLOCS portfolio with a three-dimensional, curved shade gradient between the dentin area and incisal edge [1]. In addition to integrated esthetics, both variants also impress with a variety of benefits for monolithic restorations:

Shade accuracy in line with VITA shade standards

The basis for successful monolithic restoration is the shade accuracy of the blank in line with the VITA shade standards. This is the only way that a block in the appropriate shade can be selected after tooth shade determination. VITABLOCS offer proven shade accuracy – just choosing the right block means the shade is right too [2, 3]. The portfolio in the two shade standards, VITA classical A1 – D4 and the VITA SYSTEM 3D-MASTER, offers the necessary range to find the blank with the right shade for every patient.

Appearance similar to natural dentition

It's not just the shade that has to be right – the translucence and the play of light in the restoration must replicate natural dentition in order for a monolithic restoration to be successful. Generally, all VITABLOCS blanks are made of a natural raw material called feldspar and offer optical properties similar to those of natural dentition [4]. That's why the polychromatic variants of VITABLOCS in particular, are ideal for highly esthetic single-tooth anterior restorations from a single cast.

Easy to polish

Achieving smooth surfaces when finishing is essential for monolithic surfaces. This is the only way to protect the antagonist and the restoration itself against excessive abrasion in long-term clinical outcomes. VITABLOCS blanks are comprised of a finely structured feldspar ceramic that is proven to facilitate rapid and simple polishing [5, 6]. What's more: VITABLOCS restorations can be seated immediately after finishing and polishing. Glaze firing is not required. 

Abrasion similar to enamel

In long-term clinical outcomes, harmonious abrasion behavior is desirable between the restoration and the antagonist dentition. If the monolithic restoration abrades more slowly than the enamel, premature contacts occur automatically that can result in parafunction. If the restoration abrades too fast, this puts the long-term success of the restoration at risk. VITABLOCS feature abrasion similar to that of enamel [7], which facilitates proper occlusion and durability. 

High success and survival rate

In long-term clinical outcomes, monolithic single-tooth restorations made from VITABLOCS show a high success rate and rate of survival, even in the posterior area that is subject to greater wear [8, 9]. Likewise, in clinical studies, veneers [10] and anterior crowns [11] made from feldspar ceramic demonstrated high reliability as expected. This robustness in combination with the natural esthetics of the polychromatic VITABLOCS variants is your guarantee for successful monolithic results.
