Background: One of the most significant factors in the success of dental implant procedures, can be mentioned by the quality and quantity of jaw bone. The occurrence of some problems such as trauma, infection, pathological lesions and the long-term absence of teeth in patients, it causes irregularities in the jaw bone and can get bone resorption. Sever defects after trauma or tumor resection needs bone reconstruction. Sticky bone is a new biological agent that provides stabilization of bone graft in the defect, and therefore, ameliorates tissue repairing and decreases bone loss during healing period. In this study, the evaluation of sticky bone performance to reconstruction of defects in two patients jaw's bone was considered.
Case Presentation: Two patients (1 male, 1 female) with an average age of 50 years underwent surgery, due to the history of tooth extraction. They had resorption of jaw bone for implant surgery. The teeth were 11 and 37. This study was performed in Al-Mortaza's Clinic, Qom province, Iran, from May 2016 to January 2017. 10 ml of blood were taken individually and centrifuged at 1300 revolutions per minute (rpm) for 8 minutes to separate the platelet-rich fibrin. Then, platelet-rich fibrin was combined with allogeneic bone to form sticky bone. Sticky bone prepared during implant surgery, with implant inside the patient's jaw bone was used.
Conclusion: The use of sticky bone to stimulate and induce bone resorption in toothless area was associated with increased implant's success. Sticky bone due to multiple growth factors, such as TGF-β1 and VEGF, usability is an appropriate and efficiency method for stimulation of bone resorption.
