Patient-Specific Implants as a Treatment of Oral Manifestations of Aggressive Periodontitis Accompanying Papillon-Lefèvre Syndrome. A Case Report.

Abstract

Objectives: A case report of aggressive periodontitis that accompanied Papillon-Lefèvre syndrome in a 19-year-old female patient. It demonstrates a full workflow for full mouth rehabilitation of this case using patient-specific subperiosteal implants (SPIs) with modifications in the designing and surgical installation protocol to enhance its adaptation, stability, and long-term prognosis.

Methods: A complete virtual planning was performed. Virtual extraction of teeth was done. SPIs were designed to rest on the basal bone crestally with extended prosthetic posts where implant platforms were equigingival to allow seating of the prosthesis. Surgical guides were 3D printed, and the plan was then surgically implemented. Digital design and construction of a fixed prosthesis were performed to restore teeth, gingiva, and alveolar bone.

Conclusions: The modification in the design of the SPIs performed allows for better retention and stability in addition to the fixation of a screw-retained fixed-retained prosthesis for the patient. This approach offers a predictable and efficient alternative to traditional implant therapy, particularly in cases where bone grafting is contraindicated or unlikely to succeed.
