Major Bone Augmentation with Geistlich Bio-Oss® and REGENFAST®
Treatment of a horizontal bone defect and soft-tissue deficit in the distal mandible
"I’ve used REGENFAST® several times for different treatments (gingival graft, peri-implantitis, GBR). My feelings after 1 year are: simplicity of use, speed-up of wound healing, no adverse reaction, easier handling and mixing with Geistlich Bio-Oss®."
The Situation
The patient (65 years old, female) was referred to our clinic with discomfort during masticatory function. The clinical and radiographic examination revealed an aggressive circumferential peri-implantitis lesion around an implant placed 3 years previously and a bone cyst beside the teeth.
