Porcelain Repair/Esthetic Restoration of Endodontically Accessed Crowns
Crowns are generally used to restore teeth that have a fracture, a big cavity, or a large existing filling that requires replacing. Because of this, teeth that have crowns often require endodontic therapy.
Esthetic access repairs make accessing through crowns (even brand new crowns) a complete non-issue. When done correctly, the bond achievable to porcelain is stronger than the bond achievable to dentin, eliminating the risk of root canal failure from coronal leakage. Patients always appreciate that their crown looks as good as it did before we started.
Esthetic restorations also allow for more conservative access cavities (cingulum preserving access designs) on anterior teeth, which significantly increase the prognosis of these teeth.
