In this case a long term follow-up of a sinus floor augmentation was carried out. A large Schneiderian membrane perforation was repaired using Geistlich Bio-Gide® and platelet-rich fibrin (PRF), and a sinus floor grafting was performed with Geistlich Bio-Oss® particles. A 61-year old woman came to the dental office and asked for an implant-supported prosthesis in the area of the left 2nd premolar and 1st molar. The edentulous area had a bone height of 4-5 mm. A sinus floor elevation was planned followed after 7 months by implant placement. During the opening of the lateral window to the sinus floor, a Schneiderian membrane perforation occurred caused by the rotary bur due to a very thin Schneiderian membrane. In order to repair the complete perforation site Geistlich Bio-Gide® and PRF were used to cover the perforation. Afterwards the sinus floor was elevated with 1 g of Geistlich Bio-Oss® particles. The implant had been placed 7 months after augmentation with a good primary stability. Prosthesis construction was done 4 months after implant placement. After a 2-year follow-up period, the implant showed no marginal bone resorption, the bone grafting area showed minimal volume change and good support to the implants.
Case by Assoc. Prof. Prisana Pripatnanont, Hatyai, Thailand
To demonstrate the efficiency of Geistlich Bio-Gide® for repairing a large Schneiderian membrane perforationand good long term stability of Geistlich Bio-Oss® granules in sinusgraft procedures showed minimal volume change.
Geistlich Bio-Gide® is effectively used for repairing major sinus membrane perforation and sinus augmentation with Geistlich Bio-Oss® granules is effective in bone support and stable volume.
