Atlantis Abutments Conus Dentures
Patient-specific overdenture solutions
The tapered crown principle
Atlantis Conus tapered connection ensures that the final restoration is tightly seated minimizing gaps and micro movement. Compared with bar restorations or other prefabricated connecting components, Atlantis Conus tapered crowns offer a stable and friction-locked connection that helps to eliminate problems often associated with edentulous jaws, such as:
- Pain of pressure of ill-fitting dentures
- Atrophy as a result of inactivity or pressure
- Continued bone loss requiring relining of existing denture
- Design-related difficulties with the mesostructure
A connection with a tapered cone design serves as a retaining element where tapered cap is retained on a tapered abutment by surface contact. When the retention is disconnected, the prosthesis is released, allowing for easy removal. In contrast, a parallel-walled, telescopic design creates a friction throughout the complete path of insertion.
Patients find it easier to insert a prosthesis a tapered connection design, because the bottom diameter of the tapered caps connected to the denture is always larger than the top diameter of the abutments.
Advantages for patients
The tapered crown principle effectively makes the prosthesis into a removable bridge with:
- Very high stability
- High chewing comfort
- Improved phonetics
- Optimum hygiene
