Replacement of Multiple Teeth in a Partially Dentate Posterior Mandible with a Fixed Dental Prosthesis Using an Early Loading Protocol
In 2002, a 27-year-old female patient was referred to our clinic for the treatment of her failing dentition. The patient’s medical history revealed no significant findings that would preclude routine dental procedures. She reported no drug allergies and was currently taking no medications. Her dental history was restricted to operative dentistry that addressed several areas of recurrent decay. The patient was on a periodontal recall and home care program that continually fell short of maintaining a healthy dentition.The patient’s chief complaint was: “My teeth often break, and they are sensitive when I eat and drink.”

* 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.
