Sinus Lift Surgery (Surgical)

What is Sinus Lifting? Sinus lifting is a surgical procedure performed to increase the bone volume missing in the posterior upper jaw. When the amount of bone in the area where a dental implant will be placed is insufficient, bone is added beneath the sinus cavity to make the implant possible. Thanks to the sinus lifting procedure, a solid bone structure is created especially in the posterior upper jaw, ensuring the implant's long‑term stability. When Is Sinus Lifting Required? If there is insufficient bone volume in the posterior upper jaw (the area of the molars) for implant treatment, sinus lifting may be necessary. The main conditions that cause bone loss are:

1. Tooth Loss: Prolonged tooth absence leads to natural resorption of the jawbone.
2. Structural Proximity of the Sinus: In some individuals, the sinus cavities are naturally located close to the tooth roots. In this case, the bone thickness is insufficient, making sinus lifting necessary.
3. Bone Resorption: Aging, tooth loss, or certain diseases cause resorption of the jawbone, reducing bone volume.

What Are the Sinus Lifting Techniques? The sinus lifting procedure can be performed in two ways depending on the placement and bone‑addition method:

1. Open Sinus Lifting: Chosen when the bone volume is severely insufficient. The gum is incised to reach the sinus, the sinus membrane is lifted, and bone graft material is placed in the area. After this, several months are usually allowed for new bone formation before the implant is placed.
2. Closed Sinus Lifting: Applied when the bone quantity is relatively adequate but some additional support is needed. In this technique, the implant site is prepared while the sinus membrane is lifted and bone is added. Closed sinus lifting is typically performed at the same time as implant placement.

How Is the Sinus Lifting Procedure Performed? Sinus lifting can be carried out under local anesthesia or with sedation according to the patient’s preference. The procedural steps are:

1. Gum Incision: A small incision is made in the gum to access the sinus area.
2. Elevation of the Sinus Membrane: The membrane surrounding the sinus cavity is carefully lifted and the sinus is pushed upward.
3. Placement of Bone Graft: The sinus cavity is filled with the patient’s own bone, a synthetic graft, or an animal‑derived bone graft. Over time this graft integrates with the natural bone, increasing the bone volume.
4. Healing Process: After sinus lifting, a period of 4–6 months is allowed for the added bone to fuse with the jawbone. Once the bone tissue becomes sufficiently robust, the implant can be placed.

Post‑Procedure Healing Process It is important for patients to pay attention to the healing process after sinus lifting. Key points to observe include:

• Avoid Pressure: The sinus area should not be subjected to pressure; therefore, after the procedure patients should avoid forceful breathing through the nose.
• Avoid Smoking and Alcohol: It is recommended to refrain from smoking and alcohol consumption during the healing period.
• Regular Check‑ups: Attending regular dental follow‑up appointments after the procedure is important.
• Pain and Swelling Management: Mild pain and swelling may occur, but the analgesics prescribed by the doctor will alleviate these symptoms.

What Are the Advantages of Sinus Lifting? Sinus lifting enables implant placement in the posterior upper jaw and offers several benefits:

• Strong Bone Structure: Sinus lifting creates sufficient bone volume for dental implants, ensuring the implant remains healthy for a long time.
• Improved Aesthetics and Function: Implant therapy restores chewing and speech functions and provides a natural‑looking tooth aesthetically.
• Prevents Negative Effects of Tooth Loss: It halts the resorption of the jawbone that can occur after tooth loss, preserving oral health.

Considerations for the Sinus Lifting Procedure Because sinus lifting involves delicate manipulation of the jawbone and sinus anatomy, it should be performed by an experienced periodontist or oral surgeon. After the procedure, temporary side effects such as nasal congestion, mild pain, or swelling may occur. Following the dentist’s post‑operative instructions and attending regular check‑ups speeds up healing and increases the success of the procedure.
