Bioartificial bone tissue engineering is an increasingly popular technique to repair bone defect caused by injury or disease. This study aimed to investigate the feasibility of PLLA/PCL (poly-L-lactic acid/polycaprolactone) by a comparison study of PLLA/PCL and PLLA scaffolds applied in bone regeneration. Thirty healthy mature New Zealand rabbits on which 15 mm distal ulna defect model had been established were selected and then were divided into three groups randomly: group A (repaired with PLLA scaffold), group B (repaired with PLLA/PCL scaffold), and group C (no scaffold) to evaluate the bone-remodeling ability of the implants. Micro-CT examination revealed the prime bone regeneration ability of group B in three groups. Bone mineral density of surgical site in group B was higher than group A but lower than group C. Meanwhile, the bone regeneration in both groups A and B proceeded with signs of inflammation for the initial fast degradation of scaffolds. As a whole, PLLA/PCL scaffoldsin vivoinitially degrade fast and were better suited to repair bone defect than PLLA in New Zealand rabbits. Furthermore, for the low mineral density of new bone and rapid degradation of the scaffolds, more researches were necessary to optimize the composite for bone regeneration.

Resection of the jaw is a primary option of treatment in mandibular ameloblastoma with bone damage. Mandibular resection will cause mandibular stability disturbance due toloss of some part of the bone. Instability of the mandible can cause aesthetic, physiological, and psychological malfunctioning. To restore its stability, installment of mandibular reconstruction plate on the remaining mandibular by using screws. However, it is not uncommon that plate exposure occurs following mandibular reconstruction, caused by inaccurate adaptation of the plates to the mandibular bone. A  3D stereolithography modelcan help provide the best assesment on the bone defect, plan the making of the more easily pre-operative curved plates and provide more accurate faster surgery time. Objective: To evaluate plate exposure after mandibular resection with titanium reconstruction plates in Dr. SardjitoHospital. Case report: A case was reported on mandibular reconstruction after resection of ameloblastoma with titanium plate performed in Dr. Sardjito Hospital that experienced intra-oral plate exposure and oro-cutaneous fistula on the left mandible. The clinical evaluation showed the curved titanium plate did not adapt well with the remaining mandibular bone; therefore, the titanium plate was removed without replacing it with a new plate. Inappropriate adaptationof curved titanium plate is one of the main causes of plate exposure. The use of a 3D stereolithography model is very helpful for the success of mandibular reconstruction.

Introduction: With the increase of implant-supported rehabilitation, the cases of patients with peri-implantitis become more frequent. Objective: To report the treatment of peri-implantitis by associating techniques of surface decontamination and particulate bone graft. Case report: The treatment was carried through curettage of the granulation tissue, mechanical bone decontamination withbicarbonate jet, chemical decontamination with tetracycline solution, and particulate graft in the place of the bone defect. Conclusion: After 45 postoperative days, the peri-implant tissues were health without inflammation. After 6 postoperative months, the bone defect was repaired.

Arthroplasty Revision

Introduction: The increasing number of primary total hip replacements means that there is an increased need for hip arthroplasty revisions. The periprosthetic fractures which cause bone defects can occur during removal of the femoral component and healing of these fractures can be delayed. In femoral bone defects during revisions, there are no metal augments for filling these defects. Case Report: Fifty-nine-year-old female presented with infected loosening of the left hip non-cemented endoprosthesis 5 years after surgery. The patient underwent removal of endoprosthesis. In 2 months, re-implantation of non-cemented endoprosthesis was performed and biphasic calcium phosphate (BCP) ceramic granules with hydroxyapatite/?-tricalcium phosphate (HAp/?-TCP) were implanted in the femoral bone defects. Eleven months following the arthroplasty patient had periprosthetic fracture of the distal third of the left femur. The osteosynthesis was performed and BCP ceramic granules with HAp/?-TCP were used to fill the bone defect. Long-term follow-up showed very good functional outcome and bone defect healing. Conclusion: The BCP ceramic granules with HAp/?-TCP material adjusted to the bone defect anatomy, showed effective femoral bone defect and periprosthetic fracture healing in a patient with hip arthroplasty revision and periprosthetic fracture. Keywords: Bone defect, femoral, revision.
