Sinus Lift Techniques
– Traditional Sinus Augmentation or Lateral Window Technique
– Involves making an incision in the gum and exposing the lateral boney wall of the sinus
– A window is cut to access the sinus and separate the membrane from the bone
– Bone graft material is placed in the space, and the gums are sutured closed
– Healing time is 4-12 months, with a success rate of 94%
– Osteotome Technique
– Less invasive alternative for sinus augmentation
– Suitable for sinus floor that needs to be lifted less than 4mm
– Involves making a socket in the bone near the sinus membrane and tapping the sinus floor with osteotomes to lift it
Dental implant is placed in the socket formed during the procedure
– Bone integration takes 4-8 months, stimulating bone growth and forming a thicker sinus floor
– Variations of Sinus Lift Technique
– Choice of technique depends on the specific case and surgeon’s preference
– Different techniques may be used based on the thickness and dimensions of the sinus cavity
– Presurgical planning should consider sinus dimensions and shape when choosing the appropriate technique

Complications and Risks
– Risk of sinus membrane being pierced or ripped
– Remedies include stitching the tear or placing a patch over it
Surgery may be stopped to allow the tear to heal
– Sinus membrane often grows back thicker and stronger after healing
– Other risks include infection, inflammation, pain, itching, allergic reaction, tissue or nerve damage, scar formation, hematoma, graft failure, oro-antral communication/oro-antral fistula, tilting or loosening of implants, or bleeding

Recovery and Timing
– Sinus augmentation bone takes 3 to 6 months to become part of natural sinus floor bone
– Implants are usually attempted after 6 months of healing
– Some surgeons perform both augmentation and dental implant simultaneously to avoid the need for two surgeries

History and Authors
– Oscar Hilt Tatum, Jr. performed the first maxillary sinus floor augmentation procedure in 1974
– Dr. Tatum also performed the first sinus-lift procedure in 1974
– Dr. Philip Boyne published the first article on sinus grafting in 1980
– Various authors and studies have contributed to the development and evaluation of sinus lift procedures

Cost-effectiveness and Resources
– Lateral sinus lift technique has slightly higher implant survival but substantially higher costs
– Transalveolar sinus lift technique is less invasive but may not be effective in advanced bone reduction cases
– Patient perspective and invasiveness are important decision criteria
– Additional resources on sinus lift procedures can be found on various websites and through notable researchers in the field.

Sinus lift (Wikipedia)

Maxillary sinus floor augmentation (also termed sinus lift, sinus graft, sinus augmentation or sinus procedure) is a surgical procedure which aims to increase the amount of bone in the posterior maxilla (upper jaw bone), in the area of the premolar and molar teeth, by lifting the lower Schneiderian membrane (sinus membrane) and placing a bone graft.

When a tooth is lost, the alveolar process begins to remodel. The vacant tooth socket collapses as it heals leaving an edentulous (toothless) area, termed a ridge. This collapse causes a loss in both height and width of the surrounding bone. In addition, when a maxillary molar or premolar is lost, the maxillary sinus pneumatizes in this region which further diminishes the thickness of the underlying bone. Overall, this leads to a loss in volume of bone that is available for implantation of dental implants, which rely on osseointegration (bone integration), to replace missing teeth. The goal of the sinus lift is to graft extra bone into the maxillary sinus, so more bone is available to support a dental implant.
