FP1 and FP2 implant-supported restorations
Overview
FP1 generally refers to a fixed full-arch implant restoration that replaces mainly the clinical crowns and aims to mimic natural tooth emergence.
FP2 generally refers to a fixed full-arch implant restoration that replaces teeth with elongated crowns to compensate for tissue loss, still without pink material.
This page describes the main DentalDB setup options relevant for FP1 and FP2 restorations in exocad. The exact setup may vary depending on the case configuration, selected components, and user preferences.
Step-by-step
Monolithic design
The monolithic option keeps the restoration in full contour without creating space for veneering material. The restoration is designed as a single-piece structure according to the selected workflow.
- Open the DentalDB Application and create a new project. Then, define the job for individual teeth as usual. Select the tooth number and under Work Type, select Anatomic pontic for the pontics.
-
- Then, select Anatomic crown for the implant positions and under Options & Parameters, Implant based? select Screw retained. Under Additional scans? choose the Scan Body Scan type. Additionally, with Cervical adaptation, choose between Pull to margin or Preserve tooth library shape. Click Ok and apply the same selection to the other teeth.
-
- Select the antagonist teeth as well. Then, Save the project and click Design to open DentalCAD.
-
Facial cutback
The facial cutback option is used to reduce the facial surface of the restoration and create space for veneering material. The amount of cutback can be adjusted depending on the design requirements of the case.
- Open the DentalDB Application and create a new project. Then, define the job for individual teeth as usual. Select the tooth number and under Work Type, select Reduced pontic for the pontics.
-
- Then, select Coping for the implant positions and under Options & Parameters, Implant based? select Screw retained. Under Additional scans? choose the Scan Body Scan type. Additionally, with Cervical adaptation, choose between Pull to margin or Preserve tooth library shape. Click Ok and apply the same selection to the other teeth.
-
- Select the antagonist teeth as well. Then, Save the project and click Design to open DentalCAD.

Common questions
1.The implant position is not ideal, and the screw channel may emerge between two teeth. Is there anything I can do?
Yes. In DentalDB, under Cervical adaptation, select Preserve tooth library shape. This option lets you first create an ideal wax-up before adapting the restoration to the implant position. As a result, the original tooth anatomy is preserved better and crown deformation caused by an unfavourable implant position can often be reduced. However, if the implant placement is significantly compromised, some prosthetic limitations may remain.
2.Initially, an FP1 restoration (without gingiva) was planned, but I would also like to evaluate an FP3 (with gingiva) option during the design process. Can I switch during the design process?
Yes. In Expert mode, right-click in the context menu and select Virtual Waxup Bottom. Then enable Design virtual gingiva, define the insertion direction, and confirm with OK. After that, the Gingiva design step becomes available in the context menu, allowing you to proceed with the Gingiva Base Design. To create the corresponding virtual wax-up scan, right-click again and select Generate Virtual Waxup Scan. This allows you to evaluate an FP3-style restoration even if the case was initially planned as FP1.
3.The design was initially created as monolithic. After the try-in, a facial cutback is desired for the anterior teeth. Can this modification still be performed in the same project?
First, switch to Expert mode. Then, on the Main toolbar, click Tools and select Change Reconstruction Type. Click each tooth that you want to modify and change its reconstruction type from Anatomic to Coping. Click OK to confirm. After that, right-click in the context menu and select Anatomic reduction. You can then continue with the reduction design as usual.
