What is a Sinus?
The maxillary sinuses are hollow, air-filled spaces located behind your cheeks and above your upper teeth. In some cases, Limited bone height present in the upper posterior areas and the roots of the upper teeth extend into these sinuses. When upper teeth are lost, only a thin layer of bone may remain to separate the sinus cavity from the mouth. Because dental implants require a solid foundation of bone to anchor them, the lack of sufficient bone in this area can make implant placement challenging.

A sinus augmentation, also known as a sinus lift, is a surgical procedure that increases the amount of bone in the upper jaw, specifically in the area of the molars and premolars. By lifting the sinus floor and adding bone material, this technique creates a stable base for dental implants.
The Sinus Lift Procedure
The success and longevity of dental implants depend on having enough healthy bone- height and width-to secure them. If bone loss has occurred due to gum disease, injury, or other factors, a sinus lift can help by encouraging new bone growth. Here’s how the procedure works:
- Incision and Access
A small incision is made in the gum tissue in the area of the premolars or molars to expose the jawbone. - Creating Space for Bone Material
A small opening is made in the bone, and the membrane lining the sinus is gently lifted upward to create space. - Adding Bone Material
The newly created space is filled with bone graft material. This material may come from the patient’s own body, a donor, or synthetic sources designed to mimic natural bone. - Closing and Healing
The incision is then closed with sutures, and the healing process begins. Over several months, the graft integrates with the natural bone to form a solid foundation for dental implants.
Timing for Dental Implants
The timeline for dental implant placement after a sinus lift depends on the amount of existing bone and the type of graft material used:
- Simultaneous Procedure: If there is enough bone to stabilize an implant, the sinus lift and implant placement can be done at the same time.
Delayed Placement: If the bone is insufficient, the sinus lift is performed first, and the graft is allowed to heal and integrate for several months before the implants are placed.
Benefits of Sinus Lifts
A sinus lift has made dental implants a viable option for many patients who would not have been candidates in the past. This procedure can restore functionality and provide a more secure, natural-looking alternative to loose dentures, helping patients regain confidence in their smile.
