Wichnalek remarked that their practitioners favour the hybrid ceramic VITA ENAMIC when it comes to single-tooth restorations in functionally difficult patients. This is because the material can be ground and polished or supplemented without any problems. Another advantage is the ability of the material to absorb chewing forces, which helps to relieve the masticatory apparatus. Moreover, a major advantage highlighted by Saraci was the material’s enamel-like abrasion. If a material is more resistant to abrasion than enamel, the restorations will be too high in the long term and premature contacts will occur. VITA ENAMIC wears down in harmony with the hard tooth substance. “Of course, hybrid ceramic is the material of choice if the practitioner wants to proceed in an absolutely minimally invasive manner. In the case presented, we see how very thinly and precisely the material can be ground,” Saraci said. Having received positive feedback from the four years spent working with the hybrid ceramic VITA ENAMIC, Wichnalek and Saraci are advocates of the material’s capabilities and benefits for lab processes. “It is amazing how quickly the restorations are ground out of the blocks. The material is processed without firing, and the restorations can be integrated immediately after finishing and polishing. All of this saves an incredible amount of time, which is why the five restorations could be manufactured with absolute efficiency,” said Saraci. “The shade accuracy of the polychromatic hybrid ceramic VITA ENAMIC multiColor was also the key to monolithic aesthetics in this case. VITA Zahnfabrik is, so to speak, the inventor of tooth shades; this means that the shade of the blank simply and reliably matches the specific tooth shade. This is a huge advantage when working monolithically because we buy the right tooth shade with the blank. The integrated shade gradient automatically ensures a natural appearance,” said Wichnalek. DA
