Sinus lift surgery, also known as sinus augmentation or sinus floor elevation, is a bone augmentation procedure that increases bone height in the upper jaw (maxilla) by gently lifting the Schneiderian membrane (sinus membrane) upward and placing bone graft material into the space created between the membrane and the existing bone floor. At Picasso Dental Clinic inside Vinmec Da Nang International Hospital, sinus lift procedures are performed by Dr. Le Ho Viet An and Dr. Le Thanh Toan using CBCT 3D imaging, microsurgical instruments, and premium graft materials to create the bone foundation needed for stable, long-lasting dental implants in the posterior upper jaw.
For international patients planning implant treatment in Vietnam, understanding the sinus lift procedure is important because the upper back teeth are the most common area where bone height is insufficient for implants. The maxillary sinuses – air-filled cavities above the upper jaw – naturally expand downward after upper molars are extracted, leaving too little bone for implant placement. A sinus lift solves this problem, and Da Nang offers this specialized procedure at a fraction of Western prices.
What Is a Sinus Lift?
Understanding the Anatomy
The maxillary sinuses are paired, pyramid-shaped cavities located above the upper premolars and molars on each side of the face. They are lined by a thin mucous membrane called the Schneiderian membrane. The floor of the sinus is separated from the oral cavity by a layer of bone that constitutes the posterior upper jawbone.
When upper posterior teeth are present, this bone is typically 10–13 mm tall – sufficient for dental implants. However, after tooth loss:
- The alveolar bone resorbs from below (shrinking upward)
- The sinus pneumatizes (expands downward into the bone)
- This dual process can reduce available bone to 1–5 mm – far too little for a standard implant (which needs 8–10 mm minimum)
How a Sinus Lift Restores Bone
- The surgeon accesses the sinus floor through one of two approaches (lateral or crestal)
- The Schneiderian membrane is carefully detached from the bone floor and elevated upward
- Bone graft material is packed into the space between the membrane and the original bone floor
- Over 6–9 months, the graft remodels into living bone
- The new bone provides adequate height and density for implant placement
A successful sinus lift can add 5–10 mm of bone height, enabling implant placement in areas that were previously impossible.
Who Needs a Sinus Lift?
Primary Indications
- Patients needing implants in the upper premolar or molar region with less than 8 mm of bone height below the sinus
- Patients who lost upper back teeth years ago and have experienced significant bone and sinus changes
- Patients with naturally low-positioned sinuses (large sinus cavities)
- Patients whose CBCT scan shows insufficient bone for standard implant lengths
- Patients planning All-on-4 or All-on-6 who need additional posterior bone support
When a Sinus Lift Is NOT Needed
- Patients with adequate bone height (8+ mm below sinus) confirmed by CBCT scan
- Patients receiving All-on-4 implants where the angled posterior implants bypass the sinus
- Patients choosing shorter implants (6–8 mm) that fit within the available bone
- Patients opting for removable dentures or dental bridges that do not require bone support
Medical Contraindications
- Active sinus infection or chronic sinusitis – must be resolved before surgery
- Uncontrolled diabetes – impairs bone healing
- Heavy smoking – significantly increases failure rates
- Previous sinus surgery or radiation therapy to the maxillofacial region
- Blood clotting disorders or anticoagulant therapy (requires physician coordination)
- Sinus pathology (polyps, cysts, tumors) visible on CBCT
Types of Sinus Lift Procedures
Lateral Window Sinus Lift (Open Approach)
The lateral window technique is the traditional and most versatile sinus lift method:
- A small window (approximately 10 x 15 mm) is cut in the lateral wall (cheek side) of the maxilla above the tooth roots
- The bone window is carefully infractured inward, maintaining attachment to the sinus membrane
- The Schneiderian membrane is peeled away from the bone floor and elevated upward
- Bone graft material is packed beneath the elevated membrane
- The window is covered with a resorbable collagen membrane
- The gum tissue is sutured closed
Indications: Significant bone deficiency (less than 5 mm available bone), large volume augmentation needed, bilateral sinus lifts
Advantages: Allows large volume of graft placement; can augment 5–10 mm of bone height; well-established technique with extensive long-term data
Healing time: 6–9 months before implant placement
Crestal Sinus Lift (Closed Approach)
The crestal technique (also called osteotome sinus lift or Summers technique) is a minimally invasive alternative:
- The implant drill site is prepared through the top of the ridge (crestal approach)
- An osteotome (blunt instrument) is tapped gently to fracture the thin sinus floor bone
- The sinus membrane is pushed upward through the osteotomy site
- A small amount of bone graft material is placed through the opening
- An implant can often be placed simultaneously if sufficient native bone exists (4+ mm)
Indications: Moderate bone deficiency (4–8 mm available bone), need for 1–4 mm of additional height, single implant sites
Advantages: Less invasive; faster healing; can be combined with implant placement in one surgery; less post-operative discomfort
Healing time: 4–6 months (or simultaneous with implant osseointegration)

Benefits of Sinus Lift Surgery
Enables Upper Jaw Implants
- Restores bone height where the sinus has expanded into the jaw
- Creates a stable foundation for implants in the premolar and molar region
- Allows placement of standard-length implants (10–13 mm) for maximum stability
- Makes previously “impossible” implant sites possible and predictable
Permanent Results
- Grafted bone integrates fully with native bone over 6–9 months
- The result is permanent living bone that behaves like natural jawbone
- Provides a lifelong foundation for dental implants
Predictable Outcomes
- The lateral sinus lift has a success rate of 95–98% in published literature
- Decades of clinical evidence support both the lateral and crestal techniques
- At Picasso Dental, CBCT-guided planning ensures predictable, measurable results
Improved Implant Success
- Implants placed in grafted sinus bone have comparable success rates (95–97%) to implants placed in native bone
- Adequate bone height allows for longer implants with greater surface area for osseointegration
- Proper bone volume enables ideal implant positioning for optimal function and aesthetics
The Sinus Lift Procedure at Picasso Dental Clinic, Vinmec Da Nang
Step 1: Diagnostic Evaluation
- Complete oral examination and medical history review
- CBCT 3D scan to measure residual bone height below the sinus
- Assessment of sinus anatomy, membrane thickness, and any pathology
- Determination of lateral vs. crestal approach
- Treatment plan and cost estimate
Virtual pre-consultation available for international patients – send your CBCT for assessment.
Step 2: Pre-Surgical Preparation
- Prescribe prophylactic antibiotics (started 1 day before surgery)
- Decongestant nasal spray may be prescribed to reduce sinus congestion
- Review and confirm the surgical plan
- Ensure any sinus issues (allergies, mild congestion) are resolved
Step 3: Sinus Lift Surgery (60–120 Minutes)
For lateral window approach:
- Local anesthesia administered
- Gum tissue reflected to expose the lateral wall of the maxilla
- Piezoelectric ultrasonic instruments cut the bone window precisely (safer for the membrane than rotary burs)
- The bone window is hinged inward, lifting the attached membrane
- The membrane is elevated using specialized curettes
- Membrane integrity is confirmed – any perforations are repaired with collagen patches
- Bone graft material (Bio-Oss or equivalent) is carefully packed beneath the elevated membrane
- A collagen membrane is placed over the window
- The gum tissue is repositioned and sutured
For crestal approach:
- Local anesthesia administered
- Implant osteotomy (drill site) prepared to within 1 mm of the sinus floor
- Osteotome gently tapped to fracture and elevate the sinus floor
- Bone graft material introduced through the osteotomy
- If sufficient primary stability is achievable, the implant is placed simultaneously
- The site is sutured
Step 4: Healing and Graft Maturation
- Lateral approach: 6–9 months of graft maturation before implant placement
- Crestal approach: 4–6 months if implant was placed simultaneously; 4–6 months before implant if placed alone
- Regular follow-ups monitor healing (virtual check-ins for dental tourists)
- CBCT scan at 6 months to confirm bone regeneration and density
Step 5: Implant Placement (If Not Simultaneous)
After confirmed graft maturation:
- Implants are placed through the newly regenerated bone
- Standard implant protocol followed
- Osseointegration period: 3–6 months
- Final crown or prosthesis delivered
