Everything About Close Sinus Lifting
Find all the detailed information you need about the treatment in this section.
What is Close Sinus Lifting?
Closed sinus lifting (transcrestal or osteotome technique) is a minimally invasive procedure applied in patients with moderate bone insufficiency in the posterior upper jaw region. The sinus membrane is elevated through the implant socket and a small amount of graft is added.
This technique is preferred when existing bone height is between 5-8 mm and 2-4 mm bone gain is needed. Its greatest advantage is that it can be applied in the same session as implant placement and is less invasive than the open technique.
Treatment Stages
Imaging and Planning
Existing bone height and sinus anatomy are evaluated with 3D tomography. Suitability for closed technique is determined.
Implant Socket Preparation
Drilling is stopped 1 mm short of the sinus floor. Bone floor is preserved.
Elevation with Osteotome
Sinus floor is pushed upward without breaking using special osteotomes. Membrane is elevated.
Graft Addition
Small amount of bone graft is placed in the created space.
Implant Placement
Implant is placed in the same session. Primary stability is achieved.
Close Sinus Lifting Types
Summers Osteotome Technique
Sinus floor elevation with classic osteotome set. Widely used standard method.
Hydraulic Technique
Membrane elevation with fluid pressure. Provides controlled and safe lifting.
Balloon Catheter Technique
Membrane lifting with inflatable balloon. Minimizes perforation risk.
Osseodensification
Bone densification and sinus elevation with special burs. Improves bone quality at the same time.
How Is It Done?
Closed sinus lifting is a procedure integrated with implant surgery and is completed in 30-45 minutes under local anesthesia.
Advantages
Disadvantages
Note: Most of these disadvantages can be minimized with proper planning and treatment by an experienced dentist.
