Development of an oro-antral fistula following sinus elevation surgery: a case report on management using...

The aim of this case report is to present the use of platelet-rich plasma (PRP) in the management of an oro-antral fistula occurring as a complication of lateral wall sinus augmentation. Currently, platelet-rich plasma is being used in periodontal and oral surgical practices in a wide variety of applications. The patient in this case report developed an oro-antral fistula following sinus augmentation. This was treated using platelet-rich plasma combined with a flap approach. Following clinical healing, three single-stage implants were placed and restored. Clinical and histologic results are discussed in relation to clinical management, wound healing, and regenerative outcomes of treatment. The patient has been followed up for six years.
