Arms of the Study
Arm 1
Arm 2
Active Comparator
Experimental
Control - Open flap debridement
Test - Bone replacement graft
The surgical procedure includes flap elevation, debridement of the peri-implant defect and decontamination of the implant surfaces using saline for irrigation. Flaps are replaced in their original position and carefully sutured. Patients are provided with post-surgical information and thereafter called in for regular follow-up visits.
The surgical procedure is identical to the control procedure with the exception of the application of the bone replacement graft. Following decontamination, Bio-Oss Collagen® is placed into the peri-implant bony defect. Flaps are carefully sutured and patients are provided with the same information and follow-up as patients in the control group.
