Prosthetic rehabilitation of four anterior teeth associated with the use of a nanobiomaterial in guided bone regeneration: case report

The loss of dental elements due to periodontal disease or carious lesions affects a large portion of the population, causing significant damage to patients’ oral health. In this context, the availability of nanobiomaterials and implants with high osseointegration rates allows greater predictability of treatments. The present clinical case reports the loss of teeth #11, #12, #21, and #22 due to periodontal disease and prosthetic maladaptation. The proposed treatment involved the removal of the four teeth and placement of two Systhex® implants (Curitiba, Brazil) (Avantt model, 3.5 × 13 mm) in the regions of teeth #12 and #22, associated with the use of the Nanoenxerto Blue Bone® (Curitiba, Brazil) and a Green Membrane® with dimensions of 20 × 25 mm and 1 mm thickness (Curitiba, Brazil) to cover and protect the nanograft. Subsequently, two 2-mm-high mini abutments were installed and an immediate provisional prosthesis was fabricated. After 4 months of osseointegration, a definitive screw-retained porcelain prosthesis was installed. In conclusion, the use of implants with high osseointegration rates associated with nanobiomaterials allows safe rehabilitation of patients with long-lasting and esthetic results.
