Clinical Case Report

Replacement of Two Central Incisors and One Lateral Incisor with a Fixed Dental Prosthesis on Two Bone-Level Implants

Ronald Ernst Jung

A 38-year-old woman presented with an esthetically unacceptable fixed partial denture replacing teeth 11, 21, 22. She had lost these teeth due to trauma when she was a child. The patient was not in pain but very concerned based on her previous experience that dental treatments had never satisfied her esthetic expectations. She was in good general health and reported no regular medications. No periodontal disease was noted despite the fact that the buccal flange of the prosthesis impeded cleaning of the tooth abutments. The patient did not smoke and complied with home maintenance requirements, as evidenced by her good oral hygiene status.

  • * General SAC assessment modifiers that are also part of the ERA. To avoid redundancy they are listed in this section even if no complete ERA has been made.

  • ** Not applicable to the ERA of immediate placement cases and replaced by "Socket Integrity" listed below under "Surgical SAC Classification". For all other placement types this value is a classification determinant and listed here even if no complete ERA has been made.
