Sinus Lift Surgery

When your upper jaw needs more bone for implants, we perform sinus lift surgery to build a stronger foundation.

Why choose us

Benefits of Sinus Lift Surgery

Makes Implants Possible

We add bone where the upper jaw is too thin, so upper back teeth can be replaced with implants.

Detailed 3D Planning

Our office provides CBCT and 3D imaging to help us carefully map your sinus and jawbone before surgery.

Comfortable Sedation Choices

Our team offers nitrous, oral sedation, IV sedation, and general anesthesia for patients who feel anxious.

Care Under One Roof

From imaging and bone grafting to implant placement, we handle each stage right here in our office.

Flexible Payment Options

We accept all major PPO plans and self-pay patients, and financing is available.

When a back tooth in the upper jaw has been missing for a while, the bone that once held it often thins out. At the same time, the sinus cavity just above can drop lower into that space. The result is a common problem: not enough bone height to securely anchor a dental implant. A sinus lift, also called a sinus augmentation, solves this. It gently raises the sinus membrane and adds bone graft material beneath it, creating a stable foundation where an implant can eventually be placed. At 805 Dentistry in Thousand Oaks, we perform sinus lift surgery as part of our broader implant and tooth replacement care. That means you can plan, prepare, and restore your smile with one familiar team.

A sinus lift adds bone to the upper jaw in the area of the molars and premolars, right below the maxillary sinuses. These air-filled spaces sit just above the roots of your upper back teeth. When teeth are lost, the surrounding bone naturally begins to shrink, and the sinus can expand downward. Over time, only a thin layer of bone may remain between your mouth and your sinus. During the procedure, we carefully access the area, lift the delicate sinus membrane upward, and place bone grafting material in the newly created space. As you heal, your body integrates that graft and forms a sturdier base of bone.

This procedure helps a wide range of patients. Some lost an upper back tooth years ago and are only now considering an implant. Others were told elsewhere that they "don't have enough bone" for implants. Some are planning larger treatments such as All-on-4, All-on-6, or full arch implants, where additional bone can expand their options. Because our office offers dental implants, bone grafting, and oral surgery, a sinus lift becomes one coordinated step in your plan rather than a separate referral.

Good candidates are generally people who want an implant in the upper back jaw but lack enough bone height to support one. The way to know for sure is a careful evaluation. Our practice offers CBCT imaging along with 2D and 3D dental imaging, and we have a board-certified oral and maxillofacial radiologist on staff. Detailed three-dimensional views let us measure bone height and see the position of your sinus before recommending anything.

We'll also talk through your overall dental health. Healthy gums matter for any implant-related treatment, and our periodontal team, which includes a board-certified periodontist, can address gum concerns first if needed. If you've been told you aren't an implant candidate, or simply want a second look, we're glad to review your situation and explain what your options truly are.

Will I be comfortable during and after a sinus lift?

Yes. We put a strong emphasis on comfort, and you have several options to keep you relaxed. A board-certified dental anesthesiologist is on our staff, and we offer:

  • Nitrous oxide for light relaxation
  • Oral sedation for moderate calm
  • IV sedation for deeper relaxation
  • General anesthesia when appropriate

Patients with dental anxiety often find these options make the difference between putting off care and finally moving forward. We'll help you choose the approach that fits your needs and the scope of your treatment.

After surgery, we give you clear aftercare instructions to protect the graft while it heals. This usually includes guidance on avoiding pressure changes in the sinus area, along with what to eat and how to keep the site clean. Healing takes time, because the graft needs to mature into solid bone before an implant is placed. We'll schedule follow-up visits to check your progress and decide when you're ready for the next step. Our on-site dental lab helps us keep later stages, like your final crown or implant-supported restoration, closely coordinated.

How can I pay for sinus lift surgery?

We accept all major PPO insurance plans, and we're happy to help you understand how your benefits may apply to your treatment. Coverage varies from plan to plan, so our team will review your plan with you before you commit. That way you can make decisions with a clear picture of your costs.

If you don't have insurance, we welcome self-pay patients, and financing is available to help spread the cost of treatment over time. We believe a confident, functional smile shouldn't feel out of reach. We'll walk you through your choices openly so you can focus on healing rather than worrying about the bill.

Simply reach out to our Thousand Oaks office to set up a consultation. We welcome patients from Thousand Oaks, Newbury Park, Westlake Village, Simi Valley, Moorpark, Camarillo, Agoura Hills, Oak Park, Calabasas, Oxnard, Ventura, West Hills, and Woodland Hills.
