Upper maxillary sinus lift surgery is a surgical procedure performed only by well-trained oral surgeons. The sinus mucosa is lifted during the operation, and additionally secured with a special membrane; artificial bone is added to the sinus floor thus increasing the maxillary ridge height.
Sinus floor surgery is performed when the sinus floor is too close to the implant area, i.e. the vertical bone height is too small for normal implantation. This procedure is performed in order to ensure a safe place for implants.
The goal of the sinus lifting surgery is to create a jaw ridge height which would allow for a successful implantation. The bigger the sinus expansion and dissolved jaw ridge is, the lower is the jaw height, and when planning the implant surgery, the jaw ridge height is one of the main criteria that determines the complexity and prognosis of procedure in the area of the upper jaw and the maxillary molars. Ideally, when the jaw ridge is high, implants of necessary diameter and length are threaded into the bone without additional procedures. Where the jaw ridge is low, the only option is the sinus lift surgery and there is no alternative for this operation. It is important to know that the sooner after the tooth loss decision on implants is made, the simpler the procedure is, and vice versa, the longer the delay after the tooth loss, the greater is the likelihood that it will be necessary to lift the sinus.
Course of surgery – the surgery is performed under local anaesthesia, therefore the patient does not feel any pain. Painkillers are injected in the maxillary terminal segment. When the medication becomes effective, the doctor will make an incision in the gums and pushes them away; using a but in the upper jaw he forms a window into the sinus. He lifts the sinus mucosa, which he protects with a special membrane, adds bone replacement and closes the sinus window with a protective membrane. This operation takes about 1-1.5 hours, depending on the anatomy of the sinus.
After this operation, the patient has to wait for 5-8 months. This is the approximate time for blood vessels to grow into the bone placed into the sinus; own bone production begins and the bone becomes viable. In some cases, implants can be placed already during the lift operation, thus saving 5-8 months.
With subsiding effects of painkillers in the place of surgery of the patient will start feeling aches but it is not strong and is easily controlled with non-steroidal anti-inflammatory drugs. To reduce discomfort and aches, the patient receives these drugs immediately after surgery;
- the patient is advised to use a frozen bag in the area;
- to rinse the oral cavity with antiseptics;
- in no way the patient should take hot food, hot drinks, in particularly coffee;
- the patient should not smoke for at least a few days;
- physical work in a bent position should be avoided;
- for a few weeks when sneezing or coughing, the patient should follow the doctor’s orders given after the surgery;
- diving is contraindicated.
