简要总结

To investigate the effects of concentrated growth factors applied in maxillary sinus floor elevation via a lateral window approach with simultaneous implant placement on repair of bone defects and new bone formation.

详细描述

Maxillary sinus floor elevation via a lateral window approach is the most effective method of overcoming the shortage of bone mass deficiency in atrophic maxillary posterior region. Bone transplantation is considered to be a prerequisite for the success of maxillary sinus floor elevation. Platelet-rich plasma and platelet-rich fibrin have been used to accelerate bone formation, regeneration, and repair. However, few in-depth studies are reported on the effects of concentrated growth factors on new bone formation.
