Sinus Lifts vs. Bone Grafts: Key Differences Explained by Lakeview Dental

When preparing for dental implants, we’re sure your dentist may have said these two terms: sinus lift and bone graft. Both procedures can be essential for creating the strong foundation implants need, yet they serve different purposes. At Lakeview Dental, we believe that understanding these treatments helps you make confident decisions about your oral health.

What Is a Sinus Lift?

A sinus lift, sometimes called sinus augmentation, is a specialized surgical procedure designed to add bone to the upper jaw in the region of the molars and premolars. Over time, the natural bone in this area can shrink or may not have developed enough to support an implant. Additionally, the maxillary sinuses—air spaces located above the upper teeth—can extend downward, leaving too little bone for implant stability.

During the procedure, our dentist will gently lift the sinus membrane and place bone graft material into the space created between the jaw and the sinus floor. This added bone provides the necessary support for future implants. Sinus lifts are often recommended when bone loss occurs after tooth extraction or periodontal disease.

What Is a Bone Graft?

A dental bone graft rebuilds or adds bone anywhere in the jaw where it has thinned or been lost. Bone loss can result from tooth loss, gum disease, or facial trauma. The graft strengthens the jaw and provides the density required for a stable implant.

Bone graft material may come from:

• Autograft: Your own bone
  Allograft: Donor bone from same species
• Alloplast: Biocompatible synthetic material
• Xenograft: Donor bone from another species

Your dental team will determine the best material based on your specific needs.

Key Differences Between Sinus Lifts and Bone Grafts

• Purpose:
  
  • Sinus lift: Specifically adds bone beneath the sinus floor in the upper jaw.
  • Bone graft: Can be performed anywhere in the upper or lower jaw to increase bone volume.
    
    
• Location:
  
  • Sinus lift: Upper jaw only, targeting the area near the maxillary sinuses.
  • Bone graft: Upper or lower jaw, depending on where bone is deficient.
    
    
• Procedure:
  
  • Sinus lift: Gently raises the sinus membrane before placing graft material.
  • Bone graft: Places graft material directly onto or into the existing bone.
    
    

Shared Benefits and Similarities

Despite their differences, both procedures share important goals:

• Implant Support: Each provides the bone density required for successful dental implant placement.
• Healing Period: Both typically require several months for the new bone to integrate and become strong enough to support implants.
• Graft Materials: Autografts, allografts, xenograft and synthetic materials are commonly used in either procedure.
