The patient described here is a 56-year old non-smoker and in good general health. She reported a history of dental extraction in right side of the posterior maxillary region about 3 months earlier. The treatment plan envisages a fixed prosthetic restoration, and to achieve this goal, a surgical procedure of sinus augmentation prior to implant placement was performed.
Case by Prof. Angelo Menuci Neto, Porto Alegre, Brazil & Prof. Washington Santana, Goiania, Brazil
A full-thickness flap was raised to expose the lateral wall of the sinus. After osteotomy was performed, the sinus membrane was carefully elevated and space was created for the bonegraft under the sinus membrane. Then a cut out part of Geistlich Bio-Gide® was used to obliterate the fenestration in the lower osseous wall of the sinus. The grafting material Geistlich Bio-Oss®was gently packed into the sinus cavity, followed by placement of Geistlich Bio-Gide® shaped and positioned to cover the antrostomy window. After 8 months, a dental implant was inserted into the grafted site. The prosthetic rehabilitation was performed 4 months after installing the implant.
This clinical case, with 12-month follow-up, showed the employment of Geistlich Bio-Oss® and Geistlich Bio-Gide® in sinus floor elevation for the purpose of rehabilitation with dental implants. The good prosthetic result achieved confirms the excellent osteocondutive properties for osseointegration.
