[Preliminary clinical observation for platelet-rich fibrin in site preservation].
OBJECTIVE
To observe the clinical effect on site preservation with self platelet-rich fibrin (PRF) in posterior dental areas after extraction.


METHODS
Thirty patients who asked to extract posterior teeth and were ready for dental implantation were enrolled. PRF was implanted immediately in alveolar fossa after extraction. Cone beam computer tomography (CBCT) images were taken after 4-6 months and the changes in height and width of alveolar bone were observed.


RESULTS
There was no statistical difference in the height and width between the alveolar bone treated with PRF after the extraction of tooth and the bone condition before the extraction of tooth.


CONCLUSIONS
The site preservative technology with PRF could maintain the mass of alveolar bone in posterior dental areas, which provide a better bone condition for later dental implantation.
