Trans-Osseous Sinus Augmentation™

(TOSA)

The Trans-Osseous Sinus Augmentation™ (TOSA™) – patent pending

The Trans-Osseous Sinus Augmentation™ method is designed to lift the sinus membrane off the floor of the sinus without contacting the sinus membrane.

The technique requires a minimum of 3 mm of bone to create an osteotomy.

What to Know About this Technique

When using this technique in a case where there has been longstanding tooth loss and there is well defined compact bone on the floor of the sinus, take a digital periapical x-ray to estimate the distance from the crest to the floor of the sinus. In this case, you will use your sense of touch to stop drilling when you reach the hard floor of the sinus which tells you to stop to avoid penetrating the sinus.

When using the technique in a case where there has been a recent extraction, the bone on the floor of the sinus will be soft and poorly delineated on a periapical radiograph. In these cases, a CT scan is needed to accurately measure the distance between the crest and floor of the sinus. Stop drilling 1 – 2 mm short of the sinus to avoid penetrating the sinus floor.

Procedure

  • Take a periapical x-ray (for longstanding tooth loss, a CT scan for recent extractions) to locate the floor of the sinus.
  • Use the flat ended drill in the SteinerBio TOSA™ kit to complete your osteotomy.
  • Fill the osteotomy with SteinerBio’s BioDensification bone graft material (no other bone graft will work). BioDensification is designed to flow through bone, raise the sinus membrane, and stimulate osteogenesis in the surrounding area.
  • Place the driver into the filled osteotomy slowly forcing the graft material through the remaining 1- 2 mm of bone into the sinus lifting the membrane (the membrane is lifted through hydrodynamic force caused by the forced graft material flowing through the trabecula of the bone and lifting the sinus membrane up and away from the bone).
  • Repeat the above procedure if you require to additional lift the sinus membrane for a sinus bump.
  • After lifting the membrane away from the sinus floor bone, the sinus can then be drilled into for implant placement.
  • If the sinus augmentation requires more height, drill into the sinus and continue grafting. We advise using SteinerBio’s Sinus Graft. Trim the dispensing tip of the syringe to form a seal in the osteotomy, then inject the graft material until the desired height is reached.
