CAD Crown & Bridge Design — Precision CAD/CAM for Dental Restorations

DM Dental Design provides a professional remote CAD crown design service for dental laboratories and clinics working in a digital environment. Every crown is developed to meet high standards of accuracy, aesthetics and function, so results stay predictable during manufacturing and clinical fitting.

By outsourcing crown design to an experienced CAD partner, you streamline your workflow, reduce chairside adjustments and deliver consistent restorations to your patients — without building an in-house design department.

What we focus on in every crowns & bridges case

• Marginal adaptation. Accurate margins that seat without grinding.

• Occlusal contacts. Balanced contacts checked against the antagonist.

• Anatomy. Natural morphology matched to the neighbouring teeth.

• Proximal contacts. Correct tightness for comfortable flossing.

• Emergence profile. Optimised for soft tissue health and cleaning.

Our step-by-step process

1. 1

   Submit your scanned case files and instructions.

2. 2

   We produce the digital design and send it for review.

3. 3

   After approval we deliver the final files.

4. 4

   You receive the stl file — ready for production.

How CAD/CAM crown and bridge design works

A CAD/CAM crown starts from an intraoral or model scan. Once the preparation is scanned, the margin line is drawn on the digital die, the insertion axis is defined and the software calculates the internal geometry: cement gap, spacer start and minimum wall thickness for the chosen material. Those parameters are what decide whether the restoration seats without chairside grinding, so they are set per material rather than left on a generic default.

The external anatomy is then built. For a single unit we match morphology, ridge direction and surface texture to the neighbouring teeth; for bridges we add connectors sized for the span and the material, and shape pontics so they contact the ridge in a way that can be cleaned. Occlusion is checked against the scanned antagonist, and static and dynamic contacts are adjusted before the file is exported.

The result is a milling- or printing-ready STL. Zirconia, lithium disilicate, PMMA and metal frameworks each get their own parameter set, because a design that mills well in zirconia will not necessarily press or mill well in another material.

Because the whole process is digital, every case is repeatable and documented. If a case comes back for adjustment, we work from the same project rather than starting again — which is why revisions are included rather than billed separately.

Cases we design most often

• Single anterior and posterior crowns on natural preparations
• Three-unit and long-span bridges, including cantilever designs
• Inlays, onlays and partial-coverage restorations
• Screw-retained and cement-retained implant crowns
• Full-contour and cut-back frameworks for layering

Materials and file formats

• Zirconia (monolithic and cut-back), lithium disilicate, PMMA, metal frameworks
• STL input from any modern intraoral scanner or lab scanner
• Output as STL, with the project file on request
