Bone fenestration repair with leukocyte-platelet-rich fibrin after placement of implants in the anterior maxilla: a case report.

Few reports have been published to date on the management of bone fenestration in the anterior maxilla using leukocyte-platelet-rich fibrin (L-PRF) with deproteinized bovine bone mineral allograft (DBBMA). This case report demonstrates the use of L-PRF associated with DBBMA to repair a bone fenestration after the placement of 2 implants in the anterior maxilla. Placement of 2 osseointegrated implants was planned to replace the missing maxillary central incisors of a patient with bone loss in the buccal region. Reverse treatment planning predicted the fenestration of the buccal cortical plate and exposure of the implants. The implants were placed, and fenestration of the buccal cortical bone around the body of the implants occurred as expected. A mixture of L-PRF and DBBMA, mediated by injectable platelet-rich fibrin (a combination sometimes referred to as sticky bone), was positioned to cover the defect. Cone beam computed tomography 6 months after the intervention showed complete coverage of the fenestration with newly formed bone tissue. The use of L-PRF associated with DBBMA efficiently covered the fenestration and promoted new bone formation.

Narrow-implant-retained overdenture in an atrophic mandibular ridge: a case report with 6-year follow-up.

When atrophic jaws compromise oral rehabilitation with conventional implants, narrow-diameter implants can be used. This case report describes treatment of an edentulous 75-year-old diabetic woman with a severely resorbed mandibular ridge. Her mandibular dentition was restored with an overdenture supported by 3 narrow implants and 1 mini implant. Her maxillary dentition was restored with a conventional complete denture. A 6-year clinical and radiographic follow-up confirmed that the narrow implants had provided effective stability for the overdenture, providing improvements in phonetics and masticatory ability at a low cost.
