Thanks to the careful choice of the healing screw or the implant abutment/temporary crown pair, these two entities with different regeneration po- tentials can be hermetically sealed, thereby avoiding cell competition, which we know contributes to the growth of epithelial cells that develop more rapidly. _Case No. 1 The patient presented with a fracture of #16 (Fig. 3) and periapical cysts. With the patient’s con- sent, the decision was made to perform an extraction, debridement, socket decontamination and immedi- ate placement of a non-submerged implant (implant and healing screw) using Summers’ method (crestal sinus lift). The patient was on standard premedica- tion with amoxicillin and corticosteroids. The #16 was carefully extracted by radicular separation to avoid bone fracture especially in the vestibule where Fig. 6b Fig. 6c Fig. 3_Preoperative clinical view of #16 fractured and infected.
