Early recovery of normal mastication and aesthetic performance after the extirpation of a large radicular cyst in a site from a right lower inciser tooth to the second premolar tooth in a 42-year-old male,was attained by use of two implants of one-piece screw implant, AQB (HA-coated Ti), space maker Ti plate, barrier membrane of e-PTFE and autogenous bone chips/mill transplantation. While membrane exposure was observed slightly,bone regeneration around the implants was significantly recognized by clinical evaluations and histopathological observation of biopsy after removing the barrier membrane.
It was certified that the bone formation was sufficient to retain these two implants under physiological mastication. These procedures may be recommendable as a method of early functional recovery in the case of a large bone defect.
