Background: Xenografts are well-studied materials that are often used in regenerative dentistry. Nowadays the number of surgeries involving bovine‑derived xenografts in implant dentistry has increased significantly. However, the long-term success of these materials is still not well studied. A-PRF has been used as an autogenous product that can increase the predictability of the clinical procedure by introducing many platelets growth factors.
Purpose: to describe a difficult for diagnostic and treatment clinical case and to propose a clinical protocol for resolving similar complications that can occur after guided bone regeneration.
Materials and methods: 41 years old woman complains of pain, edema and inability to chew on the upper right quadrant after a history of placed dental implants and GBR procedure. A full thickness flap was reflected starting from tooth #11 to #16. A thorough decontamination of the affected area has been done with Piezoelectric instruments and A-PRF has been introduced to improve healing process. The flap was repositioned to its original position and sutured with single interrupted resorbable 6/0 sutures. Two weeks after the procedure of surgical removal of the xenograft the patient is relieved from all preoperative symptoms and complaints.
Results: The normal architecture of the residual bone and alveolar mucosa is restored. A new CBCT is taken to evaluate the new clinical situation.
The case demonstrates that the use of bone substitutes and especially xenografts should be done with caution because they are not resorbable and a potential infection around the graft particles may have long-term biological complications.
