Low-cost implantati - jesmo li spremni na neuspjehe?

The piezoelectric knife is a relatively new technology introduced as a less radical method than classic osteotomy in oral surgery. It demonstrates a wide application range in implantology, from maxillary sinus floor elevation surgery, split crest method of ridge expansion and dental implant explantation. We present a case in which the patient referred to the Department of Oral Surgery, School of Dental Medicine in Zagreb. It was not possible to achieve a prosthetic rehabilitation of the osseointegrated implant at position 14 implanted two years ago due to the loss of the internal threads. Thereby, the abutment or cover screw could no longer be fixed in the implant. A CBCT image revealed a fully osseointegrated implant 12.5 mm long and 3.75 mm wide. Given the limited width of the bone and the patient’s desire to have an implant supported prosthodontics, implant explantation using a piezoelectric knife was chosen in order to preserve as much alveolar bone as possible. After explantation, the postoperative alveolar defect was augmented using the xenogeneic bone replacement in combination with platelet- enriched fibrin (PRF) and covered with a PRF membrane. Wound was sutured with prolene 4.0. The patient came the day after surgery, stated that he had taken ibuprofen 400 mg preventively after the procedure, was completely free of pain, swelling and any disturbances. Six months after the procedure, a check-up was made and a new dental implant placed (GC Aadva, Japan ; 12.0mm/4.0mm). High quality newly formed bone with sufficient width was observed. The surrounding soft tissue was scarless. Due to the primary stability and bone quality, implant was early prosthetically loaded with a lithium disilicate complete ceramic crown on an individually shaped CAD/CAM abutment made of zirconium oxide ceramics. For prosthetic reasons, a lithium-disilicate complete ceramic crown was also placed on the tooth 15. The use of a piezoelectic knife for dental implant explantation is a minimally invasive procedure that minimizes postoperative complications such as swelling, pain, and soft tissue damage.
