Covering a Soft-Tissue Dehiscence at a Mandibular Incisor
The early establishment of an effective soft-tissue barrier, capable of biologically protecting the peri-implant structures, is mandatory. If this soft-tissue seal were to be broken or damaged, it could be restored in the manner presented by Mario Roccuzzo in this case which is about a 70-year-old woman who was referred for implant placement to replace the four lower incisors. He was able to achieve long-term stable results using a thick connective-tissue graft from the tuberosity area.

* 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.
