Case: Ridge Augmentation with OSSIF-i Demineralized Sponge Strip

This case is presented by Dr. Kevin Frawley, DDS.

Pre-op (see case photos below)
This asymptomatic patient presented with an existing 3-unit hybrid Maryland bridge from #29-31 that had been in place for over 10 years. The esthetics were poor, and #31 showed signs of Periapical Radiolucency (PARL). After close monitoring for several months, the PARL worsened, and a buccal fistula developed. After treatment options were discussed, extraction and implant therapy was selected by the patient. Treatment aims included: improved esthetic spacing and contours, improved soft tissue health, and removal of any infection associated with the PARL.

Fixed bridge had been in place for 14 years. Treatment aimed to correct large buccal resorption on #30 area prior to implant placement.
Extraction/Graft(see case photos below)
The existing prosthesis was removed without complication. After reviewing CBCT data, it was clear that there was not enough buccal-lingual bone thickness for successful implant placement in site #30. A full thickness flap was elevated and CBCT measurements were confirmed. #31 was sectioned, atraumatically extracted, the socket cleaned with a serrated curette, and grafted with Surgical Esthetics OSSIF-i Mineralized Cancellous .25-1mm particulate allograft.

A PTFE membrane was sized and placed on the buccal of #30, ensuring coverage past the margin of the defect in all directions. Decortication potholes were made with a high-speed round carbide bur, with copious irrigation, on the buccal of site #30. Once bleeding was induced, a Surgical Esthetics OSSIF-i Demineralized Sponge Strip allograft (10x6x7mm) that had been hydrated with sterile water for 10 minutes, was placed into the buccal defect. No fixation screws or pins were used. Surgical Esthetics OSSIF-i Mineralized Cancellous .25-1mm particulate allograft was placed surrounding the sponge. The ePTFE membrane then covered the graft material, and was tucked under the lingual flap. Nylon 5-0 monofilament interrupted sutures secured the graft and membrane in place. A simultaneous root-coverage procedure was done on #29, using a bonded-suture technique. We chose not to get primary closure, to preserve the vestibule and maintain the amount of keratinized tissue. ePTFE membrane and sutures were removed after 1 month.

(Some particulate placed to fill-in around sponge after membrane placed). Due to minimal vestibular and attached tissue, primary closure was not indicated.

Implant Placement (see case photos below)
After 5 months of healing, CBCT and surgical examination confirm readiness for implant placement. Compared to pre-op CBCT data, the Surgical Esthetics OSSIF-i Demineralized Sponge Strip allograft yielded >5mm of horizontal ridge augmentation! Two implants were placed and healing caps utilized. Papilla-saving suture techniques were employed.

Restorative (see case photos below)
After 1 month, impression and restorative process commenced. Final screw-retained restorations were secured. All treatment goals were achieved. Three years later, the tissue, bone, and restoration/implant complexes are very stable.
