The maxillary sinus is a cavity located in the maxilla area, inside the maxilla bone. The shape and size of the sinus vary with each individual and will increase with aging.
If the bone height between the floor of the sinus and the roof of the mouth won’t be high enough, various surgical techniques will compensate and stimulate the bone. This is called sinus lift surgery. The purpose of this surgery is to increase the capacity and volume in the upper and lower teeth of the small and large grinding teeth for implantation.
When the teeth in this area got damaged, the floor of the sinus is slowly approaching the roof of the mouth and overtime only a thin layer of the bone separates the sinus and the mouth. As a result, the sinus will not have enough surface area and strength for implant placement. When bone height in the maxilla is not high or the sinuses are too close to the jaw, sinus lift surgery will be performed.
Procedures of Sinus Lift Surgery
Lift sinuses are generally performed in two general open and closed ways. The closed method is used to ensure that the sinus is not overly loosed. In a closed procedure with the help of a cavity created for implantation, the sinus membrane is slightly elevated and after putting the bone graft, the implant will set in the place.
In the open method, the doctor first cuts the gingival tissue in the cheek area of the sinus to reveal the bone. Then create a small oval opening on the bone that gives us access to the sinus membrane. On one side of this membrane, there is a membrane that separates the sinus and the jaw. Gradually lift the membrane upwards and separate it from the jaw.
Then, in the space between the sinus membrane and the floor of the sinus, we place the bone grafting material, in which the amount of these substances will also vary. After the bone is inserted, the gum tissue is sutured. 4 to 9 months after this surgery is the best time to do the implant.
In digital dentistry, most bony thicknesses can be performed with a closed sinus lift surgery with minimal trauma, and a digital implant can be inserted at the same time.
Sinus Lift Surgery Tips
After sinus lift surgery, you may have some swelling and bleeding.
In the event of a sneeze, you should remove the air from inside your mouth and do not blow your nose at all.
Your doctor will prescribe painkillers, antibiotics, and antimicrobial mouthwashes to prevent infection. Most patients experience only a small amount of pain after digital lift sinus.
If you have an implant immediately after the tooth extraction, the need for sinus lift surgery would be much less. In digital surgeries, this procedure is very simple, easy to handle and imposes the least trauma on the patient.
