Clinical Case Report

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

Dean Morton, James Ruskin

In November 2001, a 53-year-old female presented seeking advice and options for treatment of her maxillary incisor teeth. She was dissatisfied with both the functional and esthetic qualities of her existing restorations. Her medical health was excellent, and she reported no contraindications to dental care. On presentation, the patient’s dental health was less than ideal. Although she had no probing depths greater than 3 mm, she suffered from generalized chronic adult periodontitis and displayed multiple sites of bleeding on probing. Her remaining dentition was heavily restored, and many teeth had been endodontically treated. Areas of recurrent dental caries were noted on many teeth. Radiographically and clinically, the maxillary incisor teeth exhibited large areas of active caries, and after the splinted crowns had been removed, the teeth were determined to be non-restorable.

  • * 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.
