2. Alveolar Bone Atrophy
   • Aging or progression of periodontal disease can lead to alveolar bone resorption, resulting in insufficient bone volume. Sinus lift surgery creates new bone space in the sinus area, addressing this deficiency.
3. Severe Bone Deficiency
   • For patients with extreme bone loss, sinus lift surgery combined with bone graft materials significantly increases bone volume, laying a solid foundation for successful implant placement.

Case Studies

Case 1:

A patient experienced the loss of teeth #14, #15, and #16 due to chronic periodontal disease. An X-ray revealed that the sinus floor-to-ridge distance at tooth #16 was only 2mm, indicating severe bone deficiency.

• Procedure:
  Under local anesthesia, the dentist made an incision at the alveolar ridge crest, reflected the flap, and prepared a 4mm-diameter opening. The sinus membrane was carefully elevated by approximately 15mm, remaining intact throughout the procedure. Artificial bone graft material was placed, followed by a bio-membrane cover and suturing.
• Outcome:
  The patient recovered well postoperatively, creating favorable conditions for subsequent implant placement.

Case 2:

Another patient lost tooth #16 due to trauma. An X-ray revealed a sinus floor-to-ridge distance of 4mm.

• Procedure:
  The sinus membrane was elevated by 7mm, resulting in a total post-lift ridge height of 11mm. BIO-OSS large-particle bone graft material was used, and an Ankylos B8 implant was successfully placed.
• Outcome:
  The patient recovered quickly, and the implant achieved excellent stability with remarkable results.

These case studies demonstrate the practical applications of sinus lift surgery. By increasing bone height in the posterior maxilla, the procedure enables successful implant placement even in challenging dental scenarios. Furthermore, it highlights the crucial role of sinus lift surgery in addressing complex dental cases and improving patient outcomes.

Do sinus lifts work?

Sinus lift is beneficial, especially in cases requiring surgery or implant restoration in the maxillary sinus area, as it can increase the bone volume of the upper jaw. For patients with osteoporosis or insufficient bone height in the upper jaw, sinus lift surgery can increase the bone volume, allowing it to reach the required height for dental implants or other procedures. This is particularly important for patients needing implant restoration for missing teeth in the posterior maxilla, as sinus lift can provide sufficient support and stability for the implants.

What are the two types of sinus lift?

Yes, there are two main types of sinus lift procedures, especially for maxillary sinus lift: the internal sinus lift and the external sinus lift.

Internal Maxillary Sinus Lift: This method is generally used when the required lift height is small (usually about 3mm to 5mm). During the procedure, the surgeon creates a window through the floor or side wall of the maxillary sinus, then uses special instruments to elevate the sinus membrane upward, thereby increasing the bone height at the bottom of the sinus. The internal lift is less invasive, and the recovery time is typically quicker.

External Maxillary Sinus Lift: When a greater lift height is required (usually over 5 mm), the surgeon may opt for the external sinus lift. This procedure involves making an incision on the outer wall of the maxilla, then detaching the membrane and grafting bone powder or other bone substitutes to increase bone volume. Due to the larger surgical area, the recovery time may be relatively longer.

It is important to note that the choice of surgical method should be based on the patient’s specific condition, the purpose of the surgery, and the surgeon’s experience and skill level. When selecting the surgical approach, the surgeon will consider factors such as the patient’s age, the structural characteristics of the maxillary bone, the surgical risks, and the expected outcomes. Additionally, patients should be well-informed about the risks of the procedure and the postoperative care requirements, making a wise decision under the guidance of their doctor.
