Sinus Augmentation in the Posterior Maxillary Region: a Case Report of 0mm Bone Height.

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.

uncontrolled diabetes
pregnant or nursing
substance abuse
heavy smoker

Treatment and study plan

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.

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.

Primary outcomes

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

Time frame: 21 months

9,98mm bone height is recorded on CBCT.
