Sinus Lifting

When is sinus lifting necessary?


We strive for full upper jaw implantation without sinus lifting and bone grafting, preferring innovative prosthetic methods such as All-on-4, and All-on-6. However, sinus lifting is sometimes necessary in the following cases:

  • Small defects in the dental row: If 1-2 teeth are missing in the area of the maxillary sinus with significant bone loss.
  • Thin bone: Initially thin bone due to the large size of the maxillary sinus.
  • Loss of bone tissue: Due to trauma, complex tooth extraction, or implant removal.

What is sinus lifting?

Sinus lifting is a surgical procedure to augment bone in the upper jaw area near the maxillary sinus. It’s a type of bone grafting used before implant placement. The procedure involves lifting the membrane of the maxillary sinus and filling the resulting cavity with bone graft material.

Methods of operating:

  1. Closed sinus lifting: This method involves correcting the position of the Schneiderian membrane and introducing bone grafts through a vertical opening during implant placement. Advantages include minimal invasiveness and the possibility of simultaneous implant placement.

    1. Open sinus lifting: This method involves access through a lateral bone incision and provides higher precision during the procedure. It allows for the correction of significant bone deficiency but requires more meticulous preparation and has a higher cost.

Closed and open sinus lifting: a comparative overview

 Closed sinus liftingOpen sinus lifting
ProcedureAccess through the root canalLateral bone incision
AnesthesiaLocal anesthesia Local anesthesia + sedationLocal anesthesia General anesthesia
Implant placementSimultaneousThrough 3-6 months
IndicationsAbsence of 1-3 teeth with a bone height of at least 7 mmAbsence of 1-3 teeth with bone height less than 7 mm
Duration of surgery30-60 min1-1.5 hours

Preparation for the surgery

Before sinus lifting, patients undergo comprehensive examinations, including computed tomography and blood tests. This allows our doctors to determine the necessity and prepare for the procedure as efficiently and safely as possible.
