35 years of VITABLOCS – A scientifically proven success story
VITABLOCS – developed in the small town of Bad Säckingen – is just one example of a German invention that is known today throughout the world.
No material shaped the success of CEREC so profoundly as the VITABLOCS CAD/CAM ceramic. Without the spirit of invention, ceramic expertise and the courage of VITA Zahnfabrik, CEREC might not have become what it is today: a technology that has proven its worth for over 35 years with solid scientific data.
VITABLOCS: A classic component of CAD/CAM dentistry
The history of VITABLOCS begins at the start of the 1980s at the same time as the development of CAD/CAM-supported fabrication in dentistry. With dedication, courage, enthusiasm and perseverance, the creators of CEREC technology at the time were part of an impressive success story. Since then, the VITABLOCS CAD/CAM feldspar ceramic has solidly and reliably impressed dentists across the world, without the need for loud marketing slogans. For 35 years, single-tooth restorations made from VITABLOCS have been dealing with every day challenges. Over the years, researchers across the world have collected a wealth of data that confirms the functional and esthetic long-term stability of VITABLOCS. In addition to all the daily successes in dental practices, scientific conclusions can be drawn that are unparalleled.
The success story of VITABLOCS is shaped by some important milestones:
- 1985: The first CAD/CAM-fabricated inlay in the world made from VITABLOCS is fitted intraorally in a patient (University of Zurich).
- 1986: The monochromatic feldspar ceramic blocks VITABLOCS are available on the market and are used throughout the world in CEREC milling units.
- 2007: The polychromatic variant VITABLOCS TriLuxe forte with shade gradients from the neck to the incisal edge is launched so that esthetic needs can be effectively met.
- 2010: The portfolio is expanded with VITABLOCS RealLife. This block has a three-dimensional curved shade gradient between the dentine and the incisal edge so that even the highest esthetic demands (e.g., in the anterior region) can be realized monolithically.
Since 1990, more than 30 million VITABLOCS blanks have been processed. Today, new CAD/CAM materials must measure up time and time again in science against this established gold standard.
Study data: Inlays and onlays made from VITABLOCS
The data with the longest study periods is available for CAD/CAM-fabricated inlays and onlays. Whether the data is from individual dental practices or universities – the long-term results are outstanding.
- In a Swiss dental practice, 200 restorations of this kind were fabricated using VITABLOCS, fitted based on defined criteria, and subject to three follow-up examinations over a period of 27 years. After 10 years, the survival rate was 90.4 % [1], after 17 years 88.7 % [2] and after 27 years 87.5 % [3], which the researchers consider highly acceptable from a clinical standpoint in the daily practice routine.
- At the University of Cologne, 2328 of these types of restorations were fitted based on a defined methodology with follow-up over a period of nine years. Survival rate: 95.5 %.
- In the case of restoration of the complete occlusal surface with overlays, researchers from Austria documented a survival rate of 99.3 % after almost eight years. [4]
- 14 relevant clinical studies on inlays, onlays and overlays with VITABLOCS were also combined in a review by researchers from Brazil and Switzerland. Here, a survival rate of 91 % was determined after 10 years. [5]

Study data: Crowns and endocrowns made from VITABLOCS
Crowns and endocrowns have also been fabricated for many years from the VITABLOCS feldspar ceramic using CAD/CAM technology. Once again, the solid long-term data here from dental practices and universities is impressive.
- In a dental practice in Switzerland, 40 crowns and 25 endocrowns were fitted on molars in accordance with defined criteria. After 12 years, the survival rate of the crowns was 95 %; for the endocrowns on more severely damaged molars that had undergone root canal treatment, the rate was 90.5 %. [6]
- In a clinical study of 212 full crowns and 235 endocrowns, researchers in France established a success rate after seven years of 98.66 %. With 99.6 %, the endocrowns even achieved a slightly higher success rate in this case than the group as a whole. [7]
- At the University of Zurich, molar crowns made from VITABLOCS with a conventional macroretentive stump height were certified after five years with a survival rate of 94.6 % by researchers; with a reduced stump height and an irregular stump geometry, the rate was 92.1 %, which is also indicative of the good conditioning properties and adhesion of the feldspar ceramic. [8]

Study data: Veneers and anterior crowns made from VITABLOCS
VITABLOCS impresses demonstrably in the anterior region in dental practices and in universities with its esthetic long-term stability.
- In a dental practice in Germany, anterior teeth were treated almost exclusively using the feldspar ceramic with 509 veneers and partial crowns. Evaluation of the follow-up examination after nine and a half years showed a success rate of 94 %.
- In a review, researchers combined 13 relevant clinical studies on VITABLOCS veneers. After nine years, the restorations showed a survival rate of 87 %. [9]
Particularly the polychromatic variants VITABLOCS TriLuxe forte and VITABLOCS RealLife show their strengths in the anterior region and impress with outstanding esthetic integration.
Case study by Dr. Julio Gomez Paris (Santa Fe, Argentina)
Esthetic rehabilitation in the upper and lower jaw using VITABLOCS TriLuxe. Following bite elevation in the support area using crowns and partial crowns, it was possible to even out the fractured and abraded anterior dentition and establish a natural shade effect and morphology using monolithic material. To finish, only minimal characterization was carried out using the VITA AKZENT Plus stain system.

Overview: Reliable material properties for your daily practice routine
In addition to long-term stability during clinical follow-up, the VITABLOCS feldspar ceramic offers many proven material properties.
- Abrasion similar to enamel protects the antagonists and facilitates harmonious wear that prevents parafunction during long-term clinical follow-up. [10]
- The milling results from the CAD/CAM workflow are precise and dimensionally accurate. [11]
- The adhesive bond is proven and reliable. [12, 13, 14]
- The biocompatible material can be easily polished. [15]
- The restorations can be fitted immediately without additional firing.
- Depending on requirements, individual characterization is easily possible.
- Under clinical conditions, the material offers shade stability. [16]
- The excellent esthetics even facilitate the fabrication of challenging anterior restorations.
These proven properties facilitate efficient fabrication in the dental practice, as well as long-term intraoral stability. The proven material properties are scientifically tested and validated.
VITABLOCS has been an exciting success story for 35 years. Developed at the beginning of the 1980s in Bad Säckingen, the material is now a classic throughout the world. With the increasing prevalence of the digital workflow in dentistry, the story of VITABLOCS is sure to continue with many more chapters of scientific and real-life achievements.
