A certain height and width of the bone is required, so that an implant could be inserted and integrate with the jawbone. However, due to the close location of the sinuses, there may not be enough space for dental implants in the posterior area of the upper jaw.

Therefore, a sinus lift surgery is needed prior to implant placement. The purpose is to raise the sinus floor and fill the space with a bone material.

Axioma Dental Clinic performs all types of sinus lift surgery which are compatible with immediate implant placement.

Closed sinus lift surgery

The main indication is insufficient bone tissue quantity, although there are certain factors to be considered. The surgery can be performed using either the open or closed technique. These two procedures are equal in terms of quality, but selecting one over the other depends on the initial bone tissue volume.

A closed type surgery is performed if the bone volume is at least 5-6 mm. In all other cases, an open sinus lift procedure is performed.


Subject to all conditions, sinus lift surgery is performed in the following cases:

  • Atrophic changes in the bone tissue due to various reasons.
  • Anatomical characteristics when the sinus floor has a low location and the molar roots enter its cavity.
  • Age-related changes.
  • Bone tissue structure disorders in the sinus area.
  • Previous implant failure.


  • Blood clotting disorders.
  • Immune system diseases.
  • Head and neck oncology.
  • Sinus polyps and cysts.
  • ENT organ diseases.
  • Presence of decaying teeth, pulpitis, etc.
  • Mental disorders.
  • Poor hygienic skills of the patient.

How the surgery is performed

  1. Examination.

Examination and bone tissue volume evaluation are performed during the initial consultation. Visual examination methods, such as radiography and CT, are used to determine the tissue volume.

  1. Laboratory blood tests.

They can help to assess the state of health and check for acute diseases, acute exacerbation of chronic diseases of internal organs and infections.

  1. Oral debridement.

Before the surgery, it is necessary to eliminate all infection sources, i.e. carious teeth. Professional oral hygiene is mandatory.

  1. Surgery.

Under local anaesthesia, the doctor uses an osteotome chisel to form a site for implant insertion by lifting the sinus floor.

  1. Implant placement.

The success of the surgery depends on the qualifications of the doctor. Forming an implant site is a high-precision procedure.

Possible complications

The successful outcome of the surgery depends on the clinical picture and the doctor’s qualifications. Complications become more likely if the doctor’s post-operative recommendations are not followed.

Possible complications include:

  • Damage to the sinus. It is repaired by the doctor immediately.
  • Infecting the operating site. The first signs may appear during the surgery or later, with the cause being failure to follow the recommended oral hygiene.
  • Dislocation of the inserted material, which occurs when the doctor’s advice is not followed.
  • Bleeding, oedema or pain in the area of the stitches may sometimes occur. In this case, it is necessary to see the doctor.

Rehabilitation period

Compared to an open sinus lift procedure, a closed one is a less traumatic surgery with a lower risk of complications and a shorter rehabilitation period. If all doctor’s advice is followed, the risk of complications is minimal:

  • Food can be eaten not earlier than two hours after the surgery. All dishes should be liquid or semi-liquid and lukewarm.
  • Clean the teeth with a soft brush, being particularly careful with the operating site.
  • Avoid long trips or flights, alcohol consumption, and intensive physical exertion for 2-3 weeks.
  • It is important to take recommended drugs: antibiotics, vasoconstrictive drops, etc.
  • Avoid sneezing with your mouth closed.

Our doctors monitor the patients’ rehabilitation period at all stages. That is why it is very important to attend checkup examinations.
