Conus by Atlantis

By:

Friction Fit Overdenture

Conus is a set of parallel abutments with metal housing that fit over the abutments creating the friction needed to hold the denture in place. Patients can easily remove their denture as needed. 











Minimum Heights:


For conus abutments, the minimum required vertical height is 10.5 mm (5.5 mm for components plus 5 mm for material), with an ideal height of 13-15 mm. If a metal framework is incorporated into the prosthesis, an additional 1-1.5 mm is needed, bringing the minimum total to 12 mm.


Breakdown of the vertical height requirements:


Components: 5.5 mm of vertical space is needed for the conus abutment and SynCone cap.

  • Denture Material: An additional 5 mm is required for the acrylic base and denture teeth in an all-acrylic restoration.

  • Metal Framework: If a metal framework is used for increased strength, at least an extra 1 to 1.5 mm is needed.

Practical Considerations:

  • Planning: The process starts by creating or duplicating a complete denture to establish the desired vertical dimension of occlusion (VDO) and esthetics, then planning the implant and abutment placement based on this.

  • Measurements: The measurement for vertical space begins at the restorative platform of the dental implant and extends to the incisal edge or cusp tip of the denture tooth.

  • Ideal for Overdentures: A total of 14 mm of vertical space is a practical recommendation for acrylic-based removable overdentures, while 15 mm is recommended when a metal framework is included.

About Us

There is always something to learn...  now in my 50th year as a lab tech the landscape continues to change.  With that comes efficiencies in most cases, but not without a cost and sometimes quite the learning curve.  The idea behind RDLtechnews.online is to share experiences, new products as well as old, along with a few technical tips that we, as a lab, have come across.  If you have a question, never hesitate to ask.  If we don't have the answer, someone does!!
