Planmeca PlanScan - Occlusion Scanning

Scanning Occlusion Data
The proposal’s occlusion can be evaluated and designed using:
• Bite registration
• Buccal bite and opposing dentition
• Pre-op (a waxup or existing anatomy before preparation)
Note: Exported cases usually need to include Buccal/Opposing scans.
On the Setup tab, select Bite Registration or Buccal/Opposing. If you are scanning a pre-op,
leave the default to Buccal/Opposing.
The system will allow you to use a Time Saver method of copying the model. In certain
scenarios, this enables you to duplicate a model under another heading. You can then erase the
data that needs to be replaced and take fewer scans than if you are doing a completely new
scan.
• Pre-op model can be copied into Prep model
• Prep model can be copied into Bite Registration
The instructions below assume that you will use the Time Saver method. You always have the
option of simply doing a full scan for each model type.
Scanning a Bite Registration
A bite registration can be used to optimize occlusion for proper alignment with the opposing
tooth. Scan the preparation, ensuring there is enough detail of the adjacent dentition and/or
gingival tissue in your preparation scans to align the bite registration scans.
After scanning the preparation, prepare the bite registration.
Bite registration preparation
Keep the following recommendations in mind as you prepare bite registrations:
1 Place the bite registration material so that it completely covers the preparation surface.
• The bite registration material should not cover the adjacent teeth. If it does, trim to the
interproximal after the material sets.
• There must be sucient data of the adjacent teeth in the scans of the preparation and the
bite registration in order for the two models to align.
• Ensure there are no gaps between the bite registration material and the adjacent teeth.
