If you have had missing teeth for several years, you may have suffered some loss of bone in your jaw. This means that your jaw might not be a strong enough base for dental implants to be fitted.

Other issues with your jawbone may also mean that there is not enough bone height, or that your sinuses are too close to the jaw to allow a dental implant to be placed.

Dental implants require a certain volume of bone to “live” in. Bone grafting is a general term we use to describe procedures which help maintain the bone volume present (site preservation) or add bone to an area of the upper or lower jawbone.

Adding bone to an area which has become deficient in bone (due to the normal resorption process which occurs in the body when a tooth has been removed), will allow successful placement and healing of a dental implant.

There are several Bone Grafting techniques for different treatment scenarios and they are explored further in our Bone Grafting section.

At times, the quality and amount of bone is not enough for stability of the implants and you may need bone grafting on both single implants or All-On-4. This can be done at both the time of implant placement or prior to implant placement depending on the case.



If there is not enough bone height in your upper jaw at the back ear your sinuses then it can be hard to place a dental implant. Your dental surgeon can undertake a procedure that lifts the membrane of the sinus up and fills the area between with a bone graft.

Sinus Augmentation may be part of the All-on-4 Procedure.


There may be a situation where you have a defect in your jawbone. If you have inadequate bone, lifting the gum away from the ridge can expose a deformity.

This process is called ridge augmentation and is used to ensure the success of your new implant placement. We build a bone house around your implant with is a long term solution.
