Application of "10 Keys" Checklist and Partial Extraction Techniques to Optimize Esthetic Outcome for Adjacent Implants in the Esthetic Zone.

Placing immediate implants in the esthetic zone area poses significant challenges. Implants should be placed with consideration to hard and soft tissue management to optimize long term implant and cosmetic success. In this case report, two maxillary central incisors were extracted in two different time points, separated by 5 years because of horizontal root fractures. Implants were placed according to immediate single-tooth guidelines, using two different surgical and loading approaches, as risk assessment factors changed in the time between first immediate placement (#8) and second immediate placement (#9). These techniques included Partial Extraction Therapy (PET), the use of allograft and growth factors, connective tissue graft (CTG), platelet rich fibrin (PRF) and immediate and conventional loading. These were grouped as the "10 keys", a checklist used to pursue long term success. After 6-year and 1-year follow-up, radiographic and clinical results were satisfactory.
