Summary
Modifying CeraOne abutments by reducing height, adding a taper, or altering the cervical shoulder improves fabrication of all-ceramic crowns. This technique enhances esthetics for single-tooth implant restorations facing challenges.
Area of Science:
- Dental Prosthodontics
- Biomaterials Science
Background:
- Single-tooth implant restorations can present prosthetic crown fabrication challenges.
- Issues include divergence between implant and crown axes, insufficient interocclusal space, and supracrestal implant placement.
Purpose of the Study:
- To investigate modifications of the CeraOne abutment for improved prosthetic crown fabrication.
- To evaluate the use of the Celay-InCeram system for creating esthetic, all-ceramic crowns on modified abutments.
Main Methods:
- CeraOne abutments were modified through height reduction.
- A 15-degree taper was applied to the abutments.
- The cervical shoulder height was reduced, retaining a chamfer.
- Individual, all-ceramic crowns were fabricated using the Celay-InCeram system on modified abutments.
Main Results:
- The described modifications to CeraOne abutments are feasible.
- The Celay-InCeram system successfully produced individual all-ceramic crowns.
- The fabricated crowns demonstrated improved esthetics.
Conclusions:
- Modified CeraOne abutments can overcome common fabrication issues in single-tooth implant restorations.
- The use of the Celay-InCeram system with modified abutments offers a viable solution for achieving esthetic all-ceramic crowns.
