Tooth copyPre-op · Symmetric · Proximal

Copy a tooth in your prosthesis design: 3 methods.

Start the design from the pre-op scan, the opposite tooth or the proximal teeth. Circle One uses it as the base shape, then you refine with the smart tools.

How do you copy a tooth in dental CAD?

You give the software a reference shape: the patient’s own tooth before preparation (pre-op scan), the symmetric tooth on the other side of the arch, or the proximal teeth. In Circle One, you pick the source in the Morphology menu and the proposal starts from it.

Three methods

Which copy method for which case?

Method 1

Copy the pre-op scan

Scan the tooth before you prepare it. When the proposal opens, Circle One asks: Copy or prediction? Choose Copy to keep the original morphology.

Best for
  • Tooth intact before the prep
  • Replacing a crown with a good shape
  • Keeping the patient’s anatomy
Copier le scan pré-op
Method 2

Copy the opposite tooth

Pick Symmetric tooth in the Morphology menu. The shape of the contralateral tooth is mirrored onto the prep.

Best for
  • Anterior teeth
  • No usable pre-op scan
  • Symmetry of the smile
Copier la dent opposée
Method 3

Copy from proximal teeth

Pick Proximal teeth. The proposal follows the shape of the neighboring teeth.

Best for
  • Posterior teeth
  • Opposite tooth missing or treated
  • Harmony with the segment

Step by step

How to copy a tooth in Circle One

  1. 1

    Add the pre-op scan (optional)

    In the Scan step, drop the pre-op scan with the maxillary, mandibular and bite scans. One pre-op scan per arch. Scan control

    Ajouter le scan pré-op (optionnel)
  2. 2

    Answer Copy or prediction

    When the proposal opens, choose Copy the pre-op scan, or Do not copy for a calculated proposal.

    Répondre Copier ou prédire
  3. 3

    Change the source in Morphology

    In Global, open the Morphology menu: Pre-op, Symmetric tooth or Proximal teeth.

    Changer la source dans Morphologie
  4. 4

    Blend with a standard library

    Move the Morphology slider between patient data and a standard shape: rounded, cusped, oval, triangular or square.

    Tip

    Every combination is possible: 50% patient data, 50% library, for example.

Tooth copy FAQ

What is a pre-op scan?

A scan of the tooth before the preparation. It records the original shape so the software can copy it.

Symmetric tooth copy is designed for anterior teeth, where symmetry matters most. For posterior teeth, the proximal teeth are usually the better source.

Refine it like any proposal: Morphology, Anatomical detail, Occlusal contacts, then the Regional and Local tools. Smart tools
