Clinical Case Report

Bilateral SFE with Transcrestal and Lateral Window Technique using Various Composite Grafts

Robert Alan Levine

A 53-year old woman, a non-smoker, presented with failing crown and bridge restorations in both maxillary posterior segments. In addition, she was dissatisfied with the esthetics of her mandibular anterior sextant. She had recently lost the distal abutment (tooth 16) of a three-unit fixed partial denture (FPD) to dental caries, whereupon the bridge structure was sectioned distal to site 15. The patient’s medical history was noncontributory. The following periodontal risk factors were identified and discussed with the patient: Familial history of periodontal disease, poor/erratic compliance with preventive care.

  • * 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.
