Bone regeneration after removal of a mandibular cyst and following prosthetic reabilitation with implants. Case report
Di Dio M., De Luca M., Cammarata L., Pierazzi G.
This study shows the spontaneous bone regeneration after a Partch II surgical operation without using filling materials. The following functional and esthetic rehabilitation was made with overdenture on implants even in the recovery zone. A male patient, 59 years old, with a cystic lesion of 3.5 mm diameter in the mandibular bone was submitted to surgical enucleation of this neoformation. Postoperative radiological examinations, orthopantomography and TC DentaScan were performed to value the bone regeneration. Four implants of 10 mm diameter and 4.1 mm length weresubsequently fixed in the mandibular bone and also in the regeneration area. Then, the rehabilitation of the patient with an overdenture on implants was possible. Radiographic controls after cystic enucleation showed a good recovery of the region occupied by the neoformation. The implants fixed proved to be solid and it was possible to carry out an overdenture on them. The cystectomy alone, performed with conservative technique, without subsequent filling of the remaining cavity with biointegrative materials, permitted bone regeneration also in a large remaining cavity. This regeneration was sufficient to guarantee the success of the subsequent overdenture on implants, and very good functional and esthetic results in a patient totally edentulous in the mandibular bone.
