Sinus Augmentation In San Jose, CA: A Patient Guide

Sinus augmentation in San Jose, CA, is an oral surgery that adds bone to the upper back jaw to support future dental implants. This page from My AZ Dental provides clear information about how the procedure works, who may benefit, and what recovery looks like so you can make informed choices about your care in San Jose, California.

Sinus Augmentation Explained

Also called a sinus lift procedure, sinus augmentation increases bone height in the premolar and molar area of the upper jaw. The surgeon gently raises the sinus membrane (the thin lining inside the maxillary sinus) and places a bone graft beneath it. As the graft heals, it becomes part of your jaw, creating stable support for a dental implant.

A sinus lift is often recommended when the upper jaw has reduced bone due to tooth loss, natural anatomy, or sinus expansion over time. Modern imaging, such as a CBCT scan, helps map sinus anatomy and bone levels so treatment can be planned safely and precisely.

How Sinus Augmentation Can Help You

Patients choose sinus augmentation to make dental implant treatment possible and more predictable. Key advantages include:

• Improves implant stability by restoring vertical bone height.
• Lowers the risk of implant failure in the upper back jaw.
• Expands treatment options when traditional implants are not initially feasible.
• Provides long-term support for chewing comfort and function.
• Uses graft materials designed to integrate with your natural bone.

How The Sinus Augmentation Procedure Works

There are two common approaches your surgeon may consider based on your anatomy and goals:

• Lateral Window Approach: A small opening is created on the side of the upper jaw to lift the sinus membrane and place a bone graft. This is often used when more bone height is needed.
• Transcrestal (Osteotome) Approach: The sinus membrane is elevated through the implant site using specialized instruments, and graft material is added. This can be suitable when only a modest lift is required.

Typical steps include consultation and imaging, local anesthesia with optional sedation, gentle elevation of the sinus membrane, placement of bone graft (autograft, allograft, xenograft, or alloplast), and suturing. In select cases with adequate existing bone, an implant may be placed at the same time; otherwise, implants are usually placed after healing.

What To Expect Before And After Surgery

Before surgery, you will review your medical history, medications, and sinus health. Preoperative instructions may include pausing certain medications, arranging a ride if sedation is planned, and eating a light meal if appropriate. After surgery, mild swelling and bruising are common for two to three days.

Healing time varies, but many patients need four to nine months before implants are placed. Your provider will monitor graft integration with exams and imaging and confirm when the site is ready.

• Avoid blowing your nose for at least two weeks; sneeze with your mouth open.
• Use prescribed medications such as antibiotics, pain relievers, or saline spray as directed.
• Do not use straws, smoke, or vape during early healing.
• Sleep with your head elevated for the first few nights and apply cold compresses as advised.
• Eat soft foods and avoid chewing directly over the surgical area.
• Delay strenuous exercise and flying until cleared by your dental team.

Potential risks include sinus membrane perforation, infection, graft failure, prolonged sinus congestion, or discomfort. With careful planning and follow-up, most issues are manageable, and complications are uncommon.
