COMPLEX, COSMETIC RECONSTRUCTION OF THE

FRONT USING VITA VMK MASTER CERAMIC

Cosmetic restoration of the esthetic zone is always associated with a number of different techni-
cal challenges. In order to successfully reproduce the natural play of form, color and light in a
patient-specific, age-appropriate manner, meticulous esthetic planning is a key component. It is
possible to achieve highly predictable treatment results with great teamwork between practi-
tioners and technicians, and with the involvement of the patient. In the following, Dentist
Dr. Alexandre Richard (Lausanne, Switzerland) and Dental Technician Xavier Bosson (Châtel-
Saint-Denis, Switzerland), show how working together as a dentist and dental technician team
helped them successfully achieve the complex, cosmetic restoration of an anterior upper jaw
with veneers made of VITA VMK MASTER ceramic (VITA Zahnfabrik, Bad Säckingen, Germany)
using comprehensive analog and digital planning.
