Dental Laboratory Instruments: Complete Guide for Dentists and Dental Labs
Dental laboratory instruments are the everyday tools that connect a dentist’s impression to a finished restoration. From impression trays to forceps, knives and spatulas, the quality and precision of these instruments directly affects the accuracy of crowns, dentures and other prosthetic work. This guide explains what dental laboratory instruments are, the main categories used in Australian dental laboratories and practices, and what to look for when choosing a supplier.
What Are Dental Laboratory Instruments?
Dental laboratory instruments are the hand tools used by dental technicians and dental practices to prepare, handle and work with dental impressions, models and prosthetic materials. They sit between clinical dentistry and laboratory technology, supporting tasks such as taking impressions, mixing and shaping materials, and checking occlusion.
Unlike surgical instruments used inside the mouth during a procedure, dental laboratory instruments are typically used at the chairside for impression-taking or on the bench in a dental laboratory. Common examples include impression trays, articulating paper forceps, wax knives and plaster spatulas each designed for a specific stage of the impression-to-restoration workflow.
Why Quality Dental Laboratory Instruments Matter
The accuracy of a final restoration depends heavily on the instruments used to capture and handle the original impression. An impression tray that doesn’t seat correctly, or a spatula that doesn’t mix material evenly, can introduce distortion that carries through the entire laboratory process.
For dental practices and laboratories, instrument quality also affects day-to-day efficiency. Well-made stainless steel instruments hold their shape and edge over repeated sterilisation cycles, resist corrosion, and are more comfortable to use across a full day of procedures. This is why many Australian dental practices and laboratories prefer to standardise on professional dental laboratory instruments rather than mixing in lower-grade alternatives.
Essential Types of Dental Laboratory Instruments
A typical dental laboratory or practice will use several categories of instruments, each suited to a different stage of the workflow:
- Impression trays — used to carry and support impression material while it sets in the mouth
- Forceps — including articulating paper forceps, used to hold and position materials with precision
- Knives and spatulas — used for mixing, shaping and trimming wax, plaster and other laboratory materials
- Mixing bowls and related laboratory ware — used alongside spatulas for material preparation
Below is a closer look at the three categories most commonly searched for and purchased by Australian dental professionals.
Dental Impression Trays: Types and Uses
Impression trays are one of the most frequently used dental laboratory instruments, and they come in two main types: perforated and solid. Perforated impression trays have small holes along the tray that help mechanically retain the impression material, which is useful with alginate and similar materials. Solid impression trays rely on the material’s own adhesion or a separate tray adhesive, and are often preferred with silicone-based impression materials.
Trays are also available in different sizes and shapes to suit upper and lower arches, and in rimlock designs that provide additional retention around the tray edge. Choosing the right size and type of tray helps ensure a full, accurate impression on the first attempt, reducing the need to repeat the procedure.
AR Instrumed Australia stocks a range of dental impression trays , including perforated and solid options in various sizes, suited to general dental practices and dental laboratories across Australia.
Dental Laboratory Forceps and Articulating Paper Forceps
Forceps used in the dental laboratory and at chairside serve a different purpose to surgical extraction forceps. Articulating paper forceps, for example, are designed to hold and position articulating paper precisely between the teeth so a dentist can check occlusal contacts before and after restorative work.
Because articulating paper needs to be positioned accurately and repeatedly during a single appointment, the forceps used for this task need a secure, comfortable grip and a tip design that won’t tear the paper. Straight and curved designs are both available, allowing dentists to choose the version that suits their preferred technique and access to different areas of the mouth.

Dental Laboratory Knives and Spatulas
Knives and spatulas are the workhorses of material handling in a dental laboratory. Wax knives are used to shape, trim and smooth wax during pattern-making, while spatulas are used to mix plaster, alginate and other materials to a consistent texture before they’re loaded into an impression tray or poured into a model.
Different spatula shapes and flexibilities suit different materials and techniques — a flexible spatula, for instance, is often preferred for smoothly folding alginate into an even mix, while a more rigid spatula suits plaster work. Having a well-rounded set of dental laboratory knives and spatulas on hand allows technicians and practices to work efficiently without switching between mismatched tools.

How to Choose the Right Dental Laboratory Instruments
Selecting professional dental laboratory instruments involves weighing up several practical factors:
- Material — stainless steel instruments are the standard for durability and resistance to corrosion under repeated sterilisation
- Precision — tips, blades and grips should be manufactured to consistent tolerances, particularly for forceps and impression trays
- Ergonomics — handle shape and weight affect comfort during long clinical or laboratory sessions
- Durability — instruments should hold their shape and function through many sterilisation cycles
- Sterilisation compatibility — check that instruments are suited to your practice’s or laboratory’s sterilisation process
- Intended application — match the instrument type and size to the specific procedure, whether that’s alginate impressions, silicone impressions or wax pattern work
- Supplier reliability and support — a supplier who can answer product questions and provide consistent stock is valuable for ongoing practice or laboratory operations
Taking the time to match instrument type, size and material to your actual clinical or laboratory workflow tends to deliver better results than choosing on price alone.
