Clinical Case Report

Replacement of an Upper Right Central Incisor with a Root Fracture, Early Placement of an RC Bone Level Implant, Variobase Abutment

Chatchai Kunavisarut

A healthy 28-year-old female patient presented for a consultation on treatment options to restore her upper right central incisor. At the clinical examination, the tooth responded to percussion and palpation. The gingiva was red and slightly swollen, with a mid-facial probing depth of 10 mm. The upper right lateral incisor showed no signs or symptoms, did not respond to exploration and percussion, and the vitality test was positive. The periapical radiograph revealed that tooth 11 had been endodontically treated, with no lesion evident at the apex. A small radiopaque calcified structure surrounded by a narrow radiolucent zone (3 × 3 mm) was present at the apex of tooth 12.

* 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.
