Quick answer

A sinus lift (sinus augmentation) adds bone to the upper back jaw by gently raising the sinus membrane and placing graft material beneath it, so dental implants have enough bone height to stay stable. At A Plus Dental Clinic in Seoul, each case is planned on a 3D CT scan to choose between a crestal or lateral-window approach.

Overview of Sinus Lift Surgery

Sinus lift surgery, also known as sinus augmentation, is a specialized bone grafting procedure performed to increase bone height in the upper jaw before dental implant placement. The procedure creates sufficient bone volume beneath the maxillary sinus to support stable, long-term implants in the upper molar and premolar areas.

At A Plus Dental Clinic, sinus lift surgery is performed by an experienced implant team with over 25 years of clinical experience, following structured surgical protocols aligned with international implant standards.

Over 25 Years of Surgical and Implant Experience

Sinus lift surgery requires precise anatomical understanding, careful membrane handling, and long-term implant planning. With more than two decades of experience, the clinical team at A Plus Dental Clinic has successfully managed a wide range of sinus lift cases, including patients with severe bone loss, prior implant failure, or complex sinus anatomy.

This experience allows for accurate risk assessment, reduced complications, and predictable implant outcomes.

Why Sinus Lift Surgery Is Necessary

Bone loss in the upper jaw often occurs due to:

  • Long-term tooth loss
  • Natural sinus expansion over time
  • Periodontal disease or infection
  • Previous extractions without bone preservation

When bone height is insufficient, placing implants without sinus augmentation may compromise stability and long-term success. Sinus lift surgery restores the necessary foundation for safe implant placement.

Types of Sinus Lift Procedures

The appropriate sinus lift technique is selected based on bone height and clinical findings.

Common approaches include:

  • Internal (crestal) sinus lift for mild bone deficiency
  • Lateral window sinus lift for moderate to severe bone loss

Each technique is planned conservatively to achieve stable results while minimizing surgical trauma.

Digital Diagnostics and Surgical Planning

Every sinus lift case begins with detailed diagnostics, including 3D CT imaging to evaluate sinus anatomy, bone volume, and membrane condition. Surgical planning focuses on:

  • Safe sinus membrane elevation
  • Optimal graft placement
  • Implant positioning for long-term stability

Digital planning significantly reduces surgical risks and improves predictability.

Bone Grafting Materials and Technique

Bone graft materials are selected based on patient condition and implant goals. The graft is placed beneath the elevated sinus membrane to create new bone volume over time.

At A Plus Dental Clinic, grafting strategies prioritize long-term implant support rather than short-term placement convenience.

Sinus Lift Surgery and Implant Timing

Depending on bone condition, implants may be placed:

  • Simultaneously with the sinus lift, or
  • After a healing period once graft integration is complete

The timing is carefully determined to maximize implant stability and success rates.

Candidate Evaluation for Sinus Lift Surgery

Sinus lift surgery may be recommended for patients who:

  • Need implants in the upper back teeth
  • Have insufficient upper jaw bone height
  • Have experienced bone loss after tooth extraction
  • Are planning implant revision after previous failure

A comprehensive evaluation is required to determine suitability.

Long-Term Outcomes After Sinus Lift Surgery

When properly planned and performed, sinus lift surgery provides a stable foundation for dental implants. Patients benefit from improved implant longevity, restored chewing function, and reduced risk of implant failure.

Frequently asked questions

Is a sinus lift painful?

The procedure is done under local anaesthesia, and sedation can be arranged. Afterwards most patients feel swelling and mild discomfort for a few days, which is managed with prescribed medication and aftercare instructions.

What is the difference between a crestal and a lateral window sinus lift?

A crestal (internal) lift raises the sinus floor through the implant site and is used when only a small amount of extra bone is needed. A lateral window lift accesses the sinus from the side and is used when bone loss is moderate to severe.

Can implants be placed at the same time as the sinus lift?

Sometimes. If the remaining bone can hold the implant firmly, it may be placed during the same surgery. If not, the graft is allowed to heal first and the implant is placed later.

Can I fly after sinus lift surgery?

Flying soon after surgery can put pressure on the sinus area, so your surgeon will advise a safe interval based on the technique used. International patients receive written aftercare and travel guidance before leaving Seoul.

How do I know if I need a sinus lift?

A 3D CT scan shows the bone height between your upper jaw and sinus. If it is too low to support an implant, a sinus lift or an alternative such as shorter or angled implants will be discussed during consultation.
