Dental Laboratory Wax and Modelling Instruments Explained

Behind every well-fitting crown, bridge or denture is careful work at the bench with wax and modelling instruments. These tools let the dental technician build, shape and refine wax patterns and set-ups with precision. Here's an introduction to the main groups.

Wax carvers

Carvers are used to add, shape and carve wax into anatomical form. The Le Cron carver, with a pointed end and a spoon end, is a classic all-rounder. Hylin carvers offer slim ends for fine detail. These instruments refine cusps, grooves and margins on wax patterns.

Waxing spatulas

Waxing spatulas apply and smooth molten wax. Well-known patterns include the Fahnenstock, Lessmann and Gritman spatulas, available in different lengths for different tasks — shorter for detail work, longer for reach and leverage. A plain wax knife is used to cut and trim wax cleanly.

Spoons, mixing and cement spatulas

Lab and cement spatulas mix alginate, plaster, stone and cements smoothly on a slab or in a bowl, while bowl-ended spoons scoop and place material. Flexible blades give thorough, lump-free mixes.

Plaster instruments

Plaster knives and plaster shears trim and cut set plaster and stone casts, tidying models for articulation and finishing.

Material and care

Stainless steel is the standard for these instruments — durable, easy to clean and autoclavable. Keep working ends smooth and free of dried wax or plaster, since clean instruments give cleaner results at the bench.
