Bone and sinus treatment

Serving patients throughout Monmouthshire and wales

When a tooth is lost, the jawbone beneath it shrinks from lack of stimulation and can change the shape of your mouth. Loss of bone can also be caused by gum disease, tooth development defects, trauma, and by previous dental procedures where efforts were not made to restore natural bone.

Before dental implant treatment can begin your dentist will first need to check that there is sufficient bone for an implant to be placed successfully. If there is insufficient bone you may need to have pre-treatment before your dental implants can be placed. This may include oral surgery procedures such as bone grafting, bone expansion or sinus lifts.

At your initial consultation our implant dentist, Dr David Guppy, Dr Jim Dufty or Dr Ryan Lello, will use x-rays and scans to establish if pre-treatment is required and will explain this further.

Pre-treatment

Bone expansion

Your dentist may recommend a bone expansion if your jawbone is too narrow for a dental implant to be fitted. This involves making a small hole into your jawbone where your implant will eventually sit and using bone graft material to widen and strengthen the bone. The bone will be left to heal before a dental implant can be successfully installed.

Bone graft

Bone grafting is a treatment that is used to strengthen the area of bone your dental implant will be inserted into. This involves taking bone from elsewhere in the mouth and placing it in the area to be strengthened. After a number of months, this will fuse together, creating a stronger base for your implant.

Sinus lift

If there is not enough space to fit a dental implant in your upper jaw, Dr David, Dr Jim or Dr Ryan may recommend a sinus lift. This involves moving the sinus membrane upwards to create space in your bone for your new tooth. Once the membrane has been moved, a bone graft will fill the space that has been created to make a suitable space for your dental implant.

Once Dr David, Dr Jim or Dr Ryan is happy your bones and gums are healthy, your dental implant treatment can begin.

Book a consultation with Dr David, Dr Jim or Dr Ryan today to find out more about how dental implants could change your life!
