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 ) .
This study aims to assess the effectiveness of using calcium phosphate bone
cement in increasing the primary stability of orthodontic miniscrews by testing
its resistance to pullout forces.
This study aimed to radiographically assess the effectiveness of
the synthetic graft (Easy-Graft)™ which consists of [BCP+PLGA] in preservation of alveolar bone after teeth extraction. The sample consisted of thirty extraction cases in 28 patients (
17males 11females) and was randomly divided into two groups; study group (15 cases) where the graft had been applied after extraction and the control group (15 cases). Periapical radiographs were taken immediately after extraction,and six and fifteen months later to measure the amount of bone height decrease. Data were collected by an image analysis software and statistically analyzed. As a result,
the mean bone height decrease in the control group was (0.6mm) after extraction, (2.4mm) after six months, and (3.3mm) 15 months later.Whereas it was (0.14,1.1,1.5mm) after extraction, 6months and 15months later respectively. As such, there were statistically significant differences between the different follow-up times.Thus, (Easy-Graft)™ considered an effective method for alveolar bone preservation after teeth
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.
