Clinical Trial Summary

Sinus floor elevation (SFA) and GBR have been applied in the placement of dental implants in longstanding edentate posterior maxilla region. However, the number of study on the efficacy of these procedure on areas with 0mm bone height is limited. This case study aims to compare two cases of 0mm bone height in the posterior maxillae region with different handling procedure. In this article, two female patients in their 40s underwent maxillary sinus augmentation (sinus lifting) due to longstanding missing posterior maxillary molars with the bone of which area had resorbed entirely, leaving 0mm bone height. One patient went through conventional sinus augmentation while the other had a two-stage - sinus - lift procedure. Researchers compared the bone - volume induced between the two procedures.

Related Conditions & MeSH terms

• Bone Resorption

Intervention

Procedure:
• Conventional sinus lift surgery
After graft reflection, sinus membrane is separated from bone or oral mucosa and then bone graft is inserted in between the two structures.
• Two-stage-sinus-lift procedure
Procedure is performed in two stages with the purpose of stage one to separate the oral mucosa from the sinus membrane using a small amount of bone graft and stage two as actual sinus augmentation, which is performed similar to that of conventional sinus lift procedure.
