يعد رفع قاع الجيب الفكي من أجل وضع زرعات سنية في المنطقة الخلفية من الفك العلوي إجراء فعالاً في حالات امتصاص العظم السنخي، و مؤخراً استخدام الفبرين الغني بالصفيحات (PRF) كمادة تطعيم في عملية رفع الجيب المتزامن مع وضع زرعات سنية، وهدف هذه الدراسة هو تقييم فعالية استخدام PRF كمادة تطعيم في عملية رفع الجيب الفكي من خلال الطريق الجانبي المتزامن مع وضع الزرعات السنية.
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 augmentation 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).

The aim of the study was to evaluate the effectiveness of platelet-rich fibrin (PRF)
for closer of oroantral communication (OAC) during two months of clinical and
radiographical follow-up. Eleven patients of both sexes(45.5% males ,54.5% females)
included in this study who had (OAC) after dental extraction. The closer was done by
using fibrin clot which was plugged into the alveolar socket of the extraction site that
contains the communication, and then we sutured the fibrin membrane to the gingival
borders above it. The results revealed that (PRF) can close the oroantral communication
successfully in 81.8% of the sample with the following complications :pain 27.3% , edema
18.2% , dehiscence 18.2%. We conclude that platelet-rich fibrin can close oroantral
communication that results from dental extraction when it has been used as a clot and
membrane together with simple complicated subsequent clinical symptoms and without
radiographical signs of inflammation of the maxillary sinus.
This study was aimed to evaluate the effect of the use of Platelet-
Rich Fibrin on immediat complication following impacted
mandibular third molar surgery. forty extractions of bilateral
impacted mandibular third molars were performed in 20 volunt
eers
(18 to 25 years old). After extraction of right and left mandibular
third molars, the socket at 1 side received the autologous PRF (test
group) and the other was filled with blood clot (control group) .
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 combination of
autologous factors, platelet rich fibrin (PRF), with bone grafts,

In this study, 24 patients with posterior skeletal cross-bite were
treated at Orthodontics Department-Faculty of Dentistry in Hama
University. Hyrax expansion device was applied in all patients and
the results were assessed after active expansion
period. Cone
beam computed tomography radiograph were taken at the
assessment times.
Results showed that the midpalatal suture width has increased
significantly at all measured areas. The results revealed that
significant tipping in the canines , premolars and molars was
recorded in this study.
