Create two out of one: An amazing transformation with VITA AMBRIA and VITA LUMEX AC

When two laboratories have already been dealing with a difficult clinical situation, the planning must be meticulous and the choice of material must be appropriate for the indication. Right from start, the following was a clear departure from a typical conventional case and demanded top professional performance from the dental technical team. A young patient had been hoping for a change in the central incisors of her upper jaw, which were too wide. The true-to-shade and precisely pressable zirconia-reinforced lithium disilicate VITA AMBRIA and the multi-faceted veneering ceramic VITA LUMEX AC were selected in order to meet her high expectations. In the following, Dental Technician Abdelhalim Faris and Dentist Dr. Abdallah Farouk Redwan (both of Al-Mansura, Egypt) demonstrate how they successfully turned one front tooth into two.

Initial situation vs. final result

An unusual challenge

A 16-year-old female patient came to the practice because she had been suffering from her disproportionately wide central incisors for some time. After intraoral assessment and X-ray diagnostics, twinning was found at 11 and fusion at 21. Since both teeth needed to be treated in the same way for symmetry reasons, the decision was made to use two minimally invasive veneer treatments. The mixed shade A 2.5 was determined using the VITA classical A1-D4. After local anesthesia, minimally invasive recontouring of the gingiva and controlled preparation, the situation was moulded and a master model was made in the laboratory.

Predictable dental materials

The wafer-thin veneers were modeled in wax, sprued, embedded and burned out. This was followed by press ceramic production with VITA AMBRIA A2 HT in order to be able to become more chromatic over the course of the layering. With the zirconia-reinforced lithium disilicate, it is possible to precisely implement sharp and thin edge areas. Due to the non-existent reaction layer, homogeneous veneer surfaces appeared during divestment, which could be finished quickly and easily. Even before the veneering, there was a lively and natural-looking light dynamic, which was infused characterized using the universal veneering ceramic VITA LUMEX AC. The micro-interlocking of the ceramic particles made detailed and efficient layering possible, which was predictably reflected in the restorations, thanks to the high firing stability. Not only were the dental parts reproduced, but also the missing parts of the papilla.

A magical moment in dental technology

As part of the integration, the two lateral incisors were reduced mesially – as before on the laboratory model – so that the veneers could be tried in and then fully adhesively attached. The lateral incisors were built up and shaped into canines with filling composite. Practitioner and patient were absolutely satisfied with the final result. The perfect restorative solution was achieved through interactive dentistry and dental technology teamwork, meticulous planning and a coordinated material system.
