Sinus Lift Surgery in Tinley Park, IL

Call Now

When upper back teeth are missing for an extended period, the jawbone shrinks, and the maxillary sinuses can expand downward, leaving patients without enough bone height to support dental implants. A sinus lift addresses this directly by elevating the sinus floor and placing bone graft material beneath it. For patients in the South Suburbs of Chicago, this procedure may be the difference between being told “no” and getting the full smile they have been working toward.

At North Creek Dental Care in Tinley Park, IL, our team has served patients throughout the Southland area for over 40 years, with four doctors whose credentials span prosthodontics, periodontics, and restorative dentistry. Dr. Samuel Kang, DMD, completed a three-year advanced prosthodontics residency and an Implant Fellowship at UIC, while Dr. Charles Goodman, DDS, MS, is board-certified in periodontics and has over 25 years of experience directing one of the largest dental study clubs in the Illinois area.

The Schneiderian Membrane and Why It Matters

The key anatomical structure in a sinus lift is the Schneiderian membrane, the thin tissue lining the inside of the maxillary sinus. This membrane consists of three layers: a pseudostratified columnar epithelium, a vascular lamina propria, and the periosteum. During a sinus lift, this membrane must be carefully separated from the underlying bone and elevated upward so that bone graft material can be placed beneath it. The membrane needs to remain intact throughout the procedure. When it is handled properly, it creates a contained space where the graft can consolidate and mature into solid bone over the following months.

The thickness and condition of the membrane vary from patient to patient, which is why a thorough evaluation with cone-beam CT imaging is a standard part of treatment planning. Our team reviews each patient’s sinus anatomy before recommending a surgical approach, so the plan is always tailored to your actual anatomy.

Lateral vs. Crestal Approach: What Is the Difference?

There are two main techniques used for sinus augmentation, and the right choice depends on how much bone height remains in the upper jaw.

Lateral Window Approach

A small opening is created in the outer wall of the sinus, the Schneiderian membrane is lifted through this access point, and bone graft material is placed beneath it. This technique is preferred when there is significant bone loss and a larger volume of graft material is needed.

Crestal (Transcrestal) Approach

Access is gained through the implant preparation site, with the membrane elevated from below using specialized instruments. This minimally invasive option is well-suited to patients with greater residual bone height who require a smaller sinus lift.

Both approaches accomplish the same goal: creating enough bone volume to place implants with long-term stability. Our doctors will determine which technique is appropriate based on your imaging and overall bone health, and may also review whether bone grafting is needed alongside sinus augmentation.

Who Needs a Sinus Lift?

A sinus lift is most commonly recommended for patients who want to replace upper posterior teeth with implants but do not have adequate bone height to support them. Several factors may contribute to this situation.

  • Long-Term Tooth Loss: Missing upper back teeth for an extended period is one of the most common reasons bone volume decreases in the posterior jaw.
  • Natural Sinus Expansion: As the sinus enlarges downward over time, available bone height for implant placement is gradually reduced.
  • Periodontal Disease: Bone loss related to gum disease can leave the upper jaw with insufficient height and density for implants.
  • Prior Trauma or Extraction: Past injuries or tooth removals can affect bone volume in ways that require augmentation before implants are placed.

Patients who are otherwise good candidates for implants and are in reasonable health are often good candidates for sinus augmentation as well. A complimentary consultation with our team is the best way to determine whether you qualify. Our Meet the Doctors page provides background on the team you will work with throughout your care.

Healing and Implant Timing

After a sinus lift, the bone graft material needs time to integrate and mature before implants are placed. In most cases, this healing period ranges from 4 to 9 months, depending on the amount of bone added and your individual healing response. For patients who have more residual bone available, implants may sometimes be placed at the same appointment as the sinus lift.

Once the bone has consolidated, implant placement proceeds in the same manner as a standard implant surgery. Depending on your case, options may include a single tooth implant, a bridge supported by implants, or a fuller restoration. Research published in PMC confirms that proper sinus augmentation technique, including careful management of the Schneiderian membrane, is directly tied to long-term implant success.
