Sinus Lift (Crestal / Lateral Approach)

For many patients, bone loss in the upper jaw can make dental implant placement challenging—especially near the back molars. At Cornerstone Dental Arts, we offer sinus lift surgery using both crestal and lateral approaches to gently raise the sinus floor and add bone where it’s needed most. This advanced procedure strengthens the jaw for successful, long-term implant placement.

What Is a Sinus Lift?

A sinus lift, also known as sinus augmentation, is a specialized bone grafting procedure that adds bone to the upper jaw in the area of the molars and premolars. The goal is to increase the amount of bone between the jaw and the maxillary sinus (the air-filled space above your upper teeth).

When teeth are lost, the bone in this area naturally shrinks, and the sinus may expand downward, leaving too little bone for implant placement. A sinus lift repositions the sinus membrane upward and fills the space beneath it with bone grafting material—creating the necessary height and density for secure dental implants.


Types of Sinus Lift Procedures

At Cornerstone Dental Arts, we determine the most appropriate technique based on your unique anatomy and needs:

  1. Crestal (Internal) Sinus Lift

    • Performed through the existing implant site using a small access point.

    • Minimally invasive with shorter healing time.

    • Ideal for patients who need only minor bone height increases (typically 2–4 mm).

  2. Lateral (External) Sinus Lift

    • Used when a larger amount of bone is needed.

    • The sinus membrane is accessed from the side of the jaw, lifted gently, and filled with grafting material.

    • Provides the greatest precision and bone volume for extensive grafting needs.

Both techniques are performed with advanced imaging and gentle precision to ensure comfort and accuracy.


Why a Sinus Lift May Be Needed

You may benefit from a sinus lift if:

  • You’ve been told you don’t have enough bone for dental implants

  • You’ve had missing upper molars or premolars for several years

  • You’ve experienced bone loss due to periodontal disease or trauma

  • Your sinus floor naturally sits low or close to the upper jaw ridge

By restoring bone height in the upper jaw, this procedure makes it possible to place implants that are strong, stable, and built to last.


The Sinus Lift Process

  1. Comprehensive Evaluation
    We begin with 3D cone beam imaging to assess your bone structure and sinus anatomy.

  2. Procedure Preparation
    The area is numbed completely, and sedation is available for added comfort.

  3. Sinus Elevation & Bone Grafting
    Depending on the technique (crestal or lateral), the sinus membrane is carefully lifted, and bone graft material is placed beneath it.

  4. Healing Phase
    Over the next 4–9 months, the graft integrates with your natural bone, creating a strong foundation for implant placement.

  5. Implant Placement
    In some cases, implants can be placed during the same procedure if sufficient stability is achieved. Otherwise, placement occurs once the graft has fully healed.


Benefits of a Sinus Lift

  • Enables dental implants in areas with low bone height

  • Strengthens the jaw and promotes long-term implant success

  • Restores facial support and natural contours

  • Reduces the need for removable restorations

  • Improves both function and aesthetics of your smile

Sinus lift surgery is a powerful solution for patients who once thought implants weren’t possible.


Healing and Recovery

Most patients experience minimal discomfort after a sinus lift and return to normal activities within a few days. Post-procedure care includes:

  • Avoiding nose blowing or sneezing with force during early healing

  • Using gentle rinses to maintain cleanliness

  • Taking prescribed medications to support recovery

  • Attending follow-up appointments to monitor bone integration

Your dentist will provide personalized instructions for a smooth, comfortable healing process.


FAQs About Sinus Lift Surgery

Q: Is a sinus lift painful?
A: The procedure is performed under local anesthesia, and most patients experience only mild soreness afterward.

Q: How long before I can get implants after a sinus lift?
A: Typically between 4–9 months, depending on how quickly your bone regenerates.

Q: What type of bone is used in the graft?
A: We use safe, biocompatible materials that encourage your natural bone to grow and fuse with the graft.

Q: Can both sinuses be lifted at once?
A: Yes, bilateral sinus lifts can be performed when needed, depending on your treatment plan.

Q: What happens if I don’t get a sinus lift when needed?
A: Without adequate bone support, implants may not be possible—or could fail prematurely. A sinus lift ensures long-term stability and success.
