RESUMO
Objective: Cleft lip and palate is a congenital facial malformation with an established treatment protocol. Mixed dentition period is the best moment for correct maxillary bone defect with an alveoloplasty. The aim of this surgical procedure is to facilitate dental eruption, re-establish maxillary arch, close any oro-nasal communication, give support to nasal ala, and in some cases allow dental rehabilitation with osteointegrated implants.Study design: Twenty cleft patients who underwent secondary alveoloplasty were included. In 10 of them autogenous bone graft were used and in other 10 autogenous bone and platelet-rich plasma (PRP) obtained from autogenous blood. Bone formation was compared by digital orthopantomography made on immediate post-operatory and 3 and 6 months after the surgery.Results: No significant differences were found between both therapeutic groups on bone regeneration.Conclusion: We do not find justified the use of PRP for alveoloplasty in cleft patients treatment protocol (AU)

CONCLUSION: We do not find justified the use of PRP for alveoloplasty in cleft patients' treatment protocol.
