Brief 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.

Conditions

Bone Resorption

Outcome Measures

Primary Outcomes (1)

• Bone formation recorded after two-step-sinus-augmentation.

  9,98mm bone height is recorded on CBCT.

  21 months

Study Arms (2)

Conventional sinus lift procedure

OTHER

Participants assigned to conventional sinus augmentation

Procedure: Conventional sinus lift surgery

Two-stage-sinus-lift procedure

OTHER

Participants assigned to two-stage - sinus - lift procedure

Procedure: Two-stage-sinus-lift procedure

Interventions

Conventional sinus lift surgery PROCEDURE

After graft reflection, sinus membrane is separated from bone or oral mucosa and then bone graft is inserted in between the two structures.

Conventional sinus lift procedure

Two-stage-sinus-lift procedure 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.

Two-stage-sinus-lift procedure
