Clinical Case Report

Replacement of the Four Maxillary Incisors with a Fixed Dental Prosthesis Using an Early Loading Protocol

Stephen T Chen, Anthony John Dickinson

In March 2004, a 46-year-old female patient presented, seeking options to replace her existing acrylic maxillary removable partial denture, which replaced the four maxillary incisor teeth. She had been wearing this partial denture for approximately 15 years, the teeth having been extracted when the patient was in her early twenties. She did not want a further removable prosthesis as she was unhappy with the appearance of the flange on the denture. She was interested in exploring options for a fixed solution as long as the esthetic outcomes were not adverse. The patient was in good health, with no systemic contraindications to implant therapy. She had good oral hygiene and was a well-motivated individual with sound natural teeth and healthy periodontal support.

  • * 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.
