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.

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 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) .
Residual palatal fistulas are common after repair of palatal cleft and tumar incision in palate and nasal cavity. Repair of residual oronasal fistula is not always successful. Twolayer closure techniques that close these fistulas with soft tissue are a common practice. Turnover flaps are the most used flaps and often the sole method for nasal side closure of fistula. Anteriorly based inferior turbinate flap can be used to provide soft tissue for nasal-side closure when turnover flaps will not provide sufficient tissue for this purpose.
vestibular oro-nasal fistulas and alveolar clefts associate with cleft lip and palate. Sliding flaps are the most used flaps and often the sole method for closure of vestibular oro-nasal fistulas and alveolar clefts. cheek flap can be used instead of Sliding flaps.
