The objective of the present study was to investigate, in a sub-sinus bone augmentation model in rabbits, effect of Three Calcium Phosphate beta at different stages of the osteogenesis process. Histological and statistical analyses were performed. Rabbits underwent sinus augmentation procedures using Three Calcium Phosphate beta (Cerasorb) and Collagen membrane ( Gen Derm ) .
Graft insertion can effectively enhance the regeneration of debilitated bone. Aim: The effects of an alloplastic bone-replacing material, b-tricalcium phosphate, and of autogenous bone graft were compared.
Sinus augmentation is a common approach for patients with severe alveolar ridge atrophy. Purpose of study: The objective was to compare the hydroxyapatite + PRP with hydroxyapatite + Blood Clot in maxillary sinus grafts.
This study aims to know the effect of PRP on bone healing and regeneration after cystoectomy within studying clinical and radiological bone density changes. The research sample comprised 18 patients (14 males, 4 females) (20 cystic lesions in the upp er jaw,1-3 cm diameter). This sample was divided into 2 similar groups : The experimental group: Platelets-rich Plasma with Tri-Calcium Phosphate was applied. The control group: only Tri-Calcium Phosphate, without Platelets-rich Plasma, was applied. Both groups were observed clinically and radiologically. According to radiological observation, the digital panoramic radiographs were taken before, immediately after surgery, after 3 months, and after 6 months, respectively. Bone density measurements were done through Digora® digital program. The present study showed that there is no statistical difference between the experimental group & the control group, regarding Pain Index and Infection Index; while there was a statistical difference between the experimental group & the control group, regarding bone density after 3 and 6 months after surgery. Within the limitations of the present study, the application of autologous platelets-rich plasma (PRP) accelerates bone regeneration after cystoectomy.
Many complications are associated with the surgical removal of impacted third molars. One of these complications is the formation of a deep periodontal pocket distal to the second mandibular molar . Plasma Rich in Growth Factors is a material conta ining many growth factors Which have an essential role in wounds healing and tissue regeneration. The aim of this study was to assess the efficacy of autologous PRGF in bone regeneration techniques to prevent development of periodontal pocket at the distal root of the mandibular second molar following extraction of an impacted third molar.
