يعد رفع الجيب الفكي من العمليات الضرورية لتأمين سماكة كافية من العظم من أجل وضع الزرعات السنية في المناطق الخلفية للفك العلوي. هدفت هذه الدراسة إلى مقارنة استخدام البلاسما الغنية بالصفيحات PRP مع طعم الهيدروكسي أباتيت مع العلقة الدموية الممزوجة أيضَا بطعم الهيدروكسي الأباتيت في رفع قاع الجيب الفكي .
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.

The aim of this study is to evaluate the clinical outcomes of
treatment of temporomandibular joint disorders via injection HA &
PRP. The sample consisted of 24 patients with TMD.
Maxillary sinus augmentation is frequently necessary before placement of
dental implants in the posterior maxilla. Besides autogenous bone graft, various bone substitutes have
been used widely to augment the maxillary sinus,successful bone augmenta
tion in the maxillary sinus
without bone grafting and osseointegration of implants have been reported in several studies, recently,
successful bone reformation in the sinus using autologous platelet-rich fibrin (PRF) concentrateas an
alternative to bone grafting has been reported.
The aim of this study: was to assess the useof PRF clots and membranes as the sole filling material during
a lateral sinus lift with immediate implantation using radiologic exam (cone beam ct).
This study is aimed to evaluate the role of Platelet Rich Plasma PRP on osteogensis
in periosteal distraction. The sample consisted of 12 rabbits from local spices. The sample
divided equally into two groups, titanium mesh with holes was used in to
elevate the
periosteum and the space between the surface of bone and the mesh was filled with
collagen sponge, in the test group the sponge was injected with PRP. The rabbits were
killed after eight weeks after operation and the samples were prepared for histological
study. The histological study of specimens of control group showed formation of small
island of osteoid with large areas of connective tissue. While, in test group there was an
increasing in bone formation in form of wide area of woven bone and decreasing in
connective tissue. We conclude that application of Platelet Rich Plasma PRP lead to
improvement in bone formation in periosteal distraction.
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.
The research provides a comparison between two methods for treating osteoarthritis. In the knee joint using platelet-rich plasma injections after or without arthroscopy, the study included 100 cases every fifty of them were treated in one way and the
results were evaluated after surgery and the researcher reached the following results. Treatment with platelet-rich plasma injections after arthroscopy provided an advantage in terms of pain reduction and reduced joint effusion in the knee, improvement of the ability to rest on the limb (walking), and a marked reduction in the severity of symptoms and signs of degeneration was noted.
