[Alveolar ridge preservation with autologous dentin following cystectomy].

This case report illustrates a new application of autologous dentin for defect augmentation. After cystectomy of a follicular cyst in the maxilla, autologous particulated dentin from the wisdom tooth is used for augmentation due to periodontal compromise of neighbouring teeth. The combination of simultaneous wisdom tooth removal and augmentation is a convenient option in this case. Dentin augmentation is a cost-effective and minimally invasive autologous graft technique. The decision which treatment method for a jaw cyst is the most effective for the patient is a well discussed topic. Factors as expansion, type of cyst, localisation, duration of treatment, and predictability have to be calculated when choosing the treatment strategy. Most cysts heal without grafting, however, periodontal situation, sinus association and predictability in aesthetics led to the decision of grafting necessity in this presented case.
