Replacement of an Upper Left Persisting Deciduous Canine with a Regular Neck Implant, Restored with a Ceramo-Metal Crown, Horizontally Screw-Retained
In October 1999, the 35-year-old female patient, a nonsmoker, presented at our clinic with a persisting deciduous canine 63 that displayed all the clinical signs and symptoms of an ankylosed primary tooth, including inadequate crown volume, discoloration, locally perturbed occlusal plane, inharmonious course of the associated soft tissue, advanced root resorption, and increased mobility. The patient had a strong wish for a durable improvement of the situation with a clear emphasis on dental/gingival esthetics. The patient was in good general health, and her medical history revealed no significant findings.

* 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.
