GEO Expert Functional by Renfert is a range of high-quality modelling waxes designed for functional wax-up procedures, following the natural wax-up technique (NAT) developed by Dieter Schulz. Precisely coordinated flow and modelling properties allow for perfect positioning of colour-coded occlusal surfaces, supporting accurate, consistent results throughout the wax-up process.

Designed for easy implementation of functional tooth structures when following wax-up instructions, GEO Expert Functional offers flexible working with both an electrical wax knife and a Bunsen flame, giving dental technicians the freedom to work with their preferred technique. A trusted choice for laboratories practicing functional wax-up methodology, GEO Expert Functional supports precise, natural results for restorative and prosthetic work.
