What is a dental onlay?
A dental onlay is a partial restoration that replaces one or more cusps of a tooth while keeping the healthy structure, between an inlay and a full crown. In Circle One, you design it chairside: select Onlay on the dental map, check the margin line on the prep and the occlusal contacts, then export the file.

What your onlay prep scan should show
The preparation is a clinical decision. The design is faster when the scan makes it easy to read.
- Maxillary and mandibular scans
- A bite scan to place the antagonist
- Clear cavity walls and finish line
- Proximal teeth visible on both sides
- No moisture or debris on the margin
- Optional: a pre-op scan
Undercuts appear during the margin step: a green handle means an insertion axis with no undercut. Margin line article
