Screw Retained Bridge Design: How to deal with non-ideal implant placement

If you want to construct a screw-retained bridge, you can choose different options in the DentalDB, for the most suitable shape of the gingiva adaptation.


A) When you have ideally placed implants, a smooth transition between the tooth and the emergence profile area are possible by using Pull to Margin adaptation. With this option you adapt the library tooth to the preparation margin or emergence profile.

B) If the position of implant, is not at the desired position of library tooth, and you don't wish to adapt the teeth to the implants, choose Preserve tooth library shape in parameters.

Note: The above options are available in exocad DentalCAD 2.4 Plovdiv (Engine Build 7290)


C) If the position of implant, is not at the desired position, you can also use digital waxup feature. Setup as Anatomic waxup or Reduced waxup reconstruction type, with the option Scan waxup set to No, design waxup digitally.
