Replacement of a Compromised Upper Right Central Incisor: Hard- and Soft-tissue Augmentation, Late Placement of an RC Bone Level Implant

Paolo Casentini

A 36-year-old male patient with a compromised maxillary central incisor was referred by his general dentist for consultation. The patient’s chief complaints were the gradual debonding of a temporary crown on the right central incisor and unsatisfactory esthetics due to an increasing diastema between the right central and lateral incisors. The patient reported a traumatic event some years previously, when a crown had been placed after root-canal treatment. The referring dentist wanted to provide a new crown restoration, but was concerned about the condition of the residual root. Anamnesis was negative for any other dental or periodontal pathology in the remaining dentition. The patient reported taking no medications: He was a smoker (10 to 15 cigs/day) and had realistic esthetic expectations.

  • * 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.
