Types of Dental Waxes and Wax Carvers: Inlay, Casting, Sprue, Baseplate and More

The main types of dental waxes are pattern waxes (inlay, casting, sprue, baseplate and preformed palatal or lingual bar waxes), processing waxes (boxing, utility and dipping waxes) and impression waxes such as bite registration wax. Chase Dental Supply carries all three groups, plus the carvers, spatulas and wax pots that go with them, from Meta Dental Corp, TCS, Whip Mix, Ray Foster and Maves.

This guide sorts waxes by job and matches carvers and heaters to each bench, for crown and bridge labs, denture and flexible partial labs, schools and offices.

What Are the Types of Dental Waxes?

The types of dental waxes are usually grouped by what they do: pattern waxes, processing waxes and impression waxes.

Pattern waxes

Pattern waxes form the shape that is later replaced by metal, pressed ceramic or denture base material. Inlay wax, the classic crown and inlay pattern wax, is commonly made in harder and softer grades. Casting wax also covers preformed patterns such as clasps and mesh.

Sprue wax creates the channel that connects the pattern to the outside of the investment or flask. Baseplate wax is the pink sheet wax used for occlusal rims, record bases and denture setups.

Processing waxes

Processing waxes help you build and handle the case rather than form the final restoration. Boxing wax builds walls around an impression before pouring stone, utility wax blocks out and seals, and dipping wax forms an even coping layer over a die.

Impression waxes

Impression waxes record a relationship rather than a shape. Bite registration wax is the common example, used to capture the bite for mounting casts.

Inlay Wax vs Casting Wax: What’s the Difference?

Inlay wax is a hard, carvable wax used to build crown, inlay and bridge patterns on a die. Casting wax is the broader term for pattern waxes headed to the casting ring, and suppliers often use the two names together.

Maves Inlay Wax #2 vs #3

Maves Inlay Wax comes in two grades, each in 1 lb sticks or 1 lb chunks. Maves Inlay Wax #2 Sticks and Maves Inlay Wax #2 Chunks are described as a stiff wax. Maves Inlay Wax #3 Sticks and Maves Inlay Wax #3 Chunks are described as a hard pliable wax.

Sticks suit adding wax by instrument; chunks suit a wax pot.

40/40 Ivory Dental Casting (Inlay) Wax

40/40 Ivory Dental Casting (Inlay) Wax is an ivory colored wax used for acrylic work and diagnostic wax-ups. It is available in 1 lb or 1/2 lb sizes, in sticks or chunks.

Presentation wax for case planning

Whip Mix Life-Like Presentation Wax is a white, enamel-like wax for diagnostic and case presentation wax-ups. Whip Mix states that its opacity hides colored die stones even in thin laminate veneer wax-ups.

Which Sprue, Baseplate and Connector Waxes Do Labs Use?

The right choice depends on whether you are casting metal or injecting a flexible partial.

Meta Dental sprue, baseplate and bite wax

The Meta Dental Corp Dental Waxes listing covers casting sprue wax with reservoir in 6, 8, 10 and 12 gauge, wire and spool wax in the same gauges, Base Plate Wax in 1 lb and 5 lb boxes and Bite Registration Wax in a 3 lb box. A second Meta listing, Meta Dental Corp Waxes #740, adds preformed anterior and posterior pontic waxes, boxing wax in two thicknesses and 1 lb utility wax.

TCS sprue, palatal and lingual bar wax

TCS Sprue Wax Red .5 gauge (1 lb) is described as easy to work with, not brittle and an ideal diameter for TCS Unbreakable. TCS 9.5 Sprue Wax matches the diameter of the TCS flask opening and helps keep plaster off the sprue.

TCS Palatal Wax #5015-01 is a preformed palate, 80 per box, made at the recommended thickness of an Unbreakable palate. TCS Lingual Bar Wax #5020-01 gives you preformed lingual connector bars for clasps, flange and lingual connector areas. The TCS injection system guide explains how sprue and flask work together.

Which Dental Carvers and Wax Instruments Do You Need?

Most benches need a few hand carvers plus a heated tool for adding wax. Digital carvers hold a set temperature for consistent flow.

Hand carvers and spatulas

Meta Dental Corp Wax Carvers are sold one per pack in Bealle, Gritman, Hylin, Hylin Le Cron, Le Cron, PK1, PK2, PK4, Roach and Zahle patterns. PK style instruments are the familiar choice for adding and shaping occlusal anatomy, while Le Cron and Roach patterns are general carving workhorses.

TCS offers German steel double ended instruments: the TCS Wax Carver (spatula and carver), the TCS Wax Spatula and the TCS Fahnstock Wax Knife and Spatula with a wooden handle.

Digital carvers

The Whip Mix Digital Wax Carving Pencil uses a built-in digital circuit to hold your temperature, displays it in Celsius or Fahrenheit and remembers the last setting after power off. It ships with two tips (Offset Explorer and PKT 2).

Meta Dental Corp Digital Wax Carvers include the Digital Dual Wax Carver S500, the Digital Dual Wax Carver Touch S150, the Digital Single Wax Carver E420, the S542 electrical heating tool set and replacement tips #1 through #11.

Wax pots and heaters

A wax pot keeps dipping and inlay wax liquid at a steady temperature. The Meta Dental Corp Wax and Dipping Pots listing includes the BesQual E100 digital wax pot with 4 compartments and a 50C to 120C (122F to 248F) range, plus the S200 digital dipping pot, S800 multi digital dipping pot and S900 Multi-Waxer.

Ray Foster keeps it simple. The Ray Foster Standard Electric Wax Heater has a single preset temperature of 160F, and the Ray Foster Electric Wax Heater with Thermostat Control adjusts from 100F through 250F with three compartments and a hinged lid.

Which One Should You Choose?

Start with the work your bench does most often.

• Crown and bridge lab: Maves Inlay Wax #2 or #3 (try both grades), Meta dipping and margin wax, Meta casting sprue wax, a set of PK carvers and a digital carver or the Meta E100 wax pot. Pair it with the right investment using our Whip Mix investment guide.
• Flexible partial lab: TCS Sprue Wax, TCS 9.5 Sprue Wax, TCS Palatal Wax and TCS Lingual Bar Wax, plus TCS spatulas.
• Denture lab: Meta Base Plate Wax in 5 lb boxes, boxing and utility wax, and a Ray Foster thermostat heater.
• Dental office or school clinic: 40/40 Ivory Casting Wax or Whip Mix Life-Like Presentation Wax for diagnostic wax-ups, bite registration wax and a Whip Mix Digital Wax Carving Pencil.

Frequently Asked Questions

What are the main types of dental waxes?

Dental waxes are grouped into pattern waxes, processing waxes and impression waxes. Inlay, casting, sprue and baseplate waxes are pattern waxes, boxing and utility waxes are processing waxes, and bite registration wax is an impression wax.

What is the difference between Maves Inlay Wax #2 and #3?

Maves Inlay Wax #2 is sold as a stiff wax, and Maves Inlay Wax #3 is sold as a hard pliable wax. Both come in 1 lb sticks or 1 lb chunks.

What is sprue wax used for?

Sprue wax forms the channel that connects a wax pattern to the outside of the investment or flask, so metal or injected material can fill the mold. Meta Dental Corp offers 6 to 12 gauge casting sprue wax, and TCS offers sprue wax sized for its flexible partial flask.

Which dental carvers should a lab start with?

A practical starter set is a PK1 or PK2 for adding wax, a Le Cron or Roach for general carving and a wax spatula. Many labs add a digital carver such as the Whip Mix Digital Wax Carving Pencil for consistent heat.

Do I need a wax pot or a wax heater?

A wax pot or heater keeps wax melted at a steady temperature for dipping copings and adding wax quickly. Ray Foster heaters offer a 160F preset or a 100F to 250F thermostat, and the Meta BesQual E100 is a 4 compartment digital pot.

Knowing the types of dental waxes makes ordering simple: a pattern wax per case type, supporting processing waxes, and a carver and heater for your bench. Chase Dental Supply carries waxes and instruments from Meta Dental Corp, TCS, Whip Mix, Ray Foster and Maves. Questions about a wax grade or gauge? Email sales@chasedentalsupply.com.
