Glossary

Dental CAD design terms, in plain language.

The vocabulary that shows up across crown & bridge, implant, removable, and full-arch design — defined simply, without the jargon-on-jargon.

Margin Fit

How precisely the edge of a crown or restoration meets the natural tooth structure at the prep line. Tighter margin fit means less risk of decay or sensitivity at the edge of the restoration.

Emergence Profile

The contour of a restoration as it transitions from the implant or tooth root up through the gum line, shaping how natural the final crown looks and how it supports the surrounding gum tissue.

Occlusion

How the upper and lower teeth meet and interact when biting or chewing. Correct occlusion is checked during quality control on every crown, bridge, or denture design.

Contact Tightness

How firmly two adjacent teeth touch at their interproximal (side-by-side) surfaces. Contacts that are too loose can trap food; too tight can make flossing difficult.

Scan Body

A small marker attached to a dental implant during intraoral scanning, used to record the implant's exact position and angle so the CAD software can design an accurately fitting abutment or crown.

Verification Jig

A rigid, often 3D-printed frame used to confirm that a full-arch implant framework fits precisely in the mouth before the final prosthesis is fabricated, reducing the risk of a misfit final restoration.

Coping

The underlying framework or substructure of a crown, designed before any esthetic layering or staining is added on top.

Full Contour

A crown or restoration designed and milled as a single solid piece (monolithic), rather than a coping with separate layered porcelain on top.

Veneer / Layered Design

An esthetic crown design built with a substructure plus hand-layered or digitally-layered porcelain on top, typically used for anterior (front) teeth where natural translucency matters most.

Anatomical Base

A denture base designed with natural-looking contours that mimic real gum tissue, rather than a flat or simplified shape.

Non-Anatomical Base

A simplified, flatter denture base design, often chosen for specific clasp or fit requirements rather than esthetics alone.

Clasp Design

The metal component of a removable partial denture that grips onto remaining natural teeth to hold the prosthesis in place.

Bar / Substructure

A milled titanium or CoCr framework that a full-arch prosthesis attaches to, typically compatible with locator or ball attachment systems.

Hybrid Prosthesis

A fixed or removable full-arch restoration, often built around a bar or substructure, combining a supporting framework with denture teeth for All-on-X style cases.

Digital Smile Design (DSD)

Case planning and visualization of a smile makeover using patient photos and scan data, done before any physical lab work begins, to help clinicians present treatment options to patients.

STL File

The standard 3D file format used to represent scanned teeth, gums, and dental designs, readable by both 3Shape and exocad and compatible with most milling and printing hardware.

Monolithic Zirconia

A crown milled from a single solid block of zirconia ceramic, without a separate coping and layering step, valued for strength and simpler fabrication.

e.max

A lithium disilicate ceramic material commonly used for esthetic crowns and veneers, valued for its natural translucency.

PFM (Porcelain-Fused-to-Metal)

A crown design with a metal substructure and porcelain layered on top, an older but still widely used approach balancing strength and esthetics.

Try-In Stage

An intermediate fitting step for removable dentures, checking fit, bite, and esthetics before finalizing the design, often priced and scheduled separately from the final delivery.
