Bone and sinus treatment

Serving patients throughout East Sussex and Crowborough

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 Ashley Sim, 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 Ashley 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 Ashley is happy your bones and gums are healthy, your dental implant treatment can begin.

I have been going to the practice for many years. I see the hygienist and dentist every 6 months. I know them very well and feel relaxed on my visits. I seldom need anything to be done by the dentist.

I am very satisfied with the quality of the treatment, Jacob is probably the best dentist that I have ever seen. However, having just I am very concerned about the cost.

Sharon is excellent

10th July 2026

I am a regular patient who is prepared to drive 150 and stay over for the expert treatment I receive from Durban. The Reception staff are professional and friendly and keep my nervousness in mind each time I arrive. I have recently received treatment for a bridge that has taken 3 visits ( that’s 900 miles, up and down from Norfolk) and your surgery is worth every penny and every minute. I trust Durban and the staff.

Jacob has a really pleasant approach. He recommended that I use little sticks between my teeth. I have never got on with these but since the appointment Have purchased and used the 'sticks' and it's going well.

4th July 2026

The Dentist that conducted the check up was very professional, the procedure was made very clear with a good debrief at the end. I was made to feel very comfortable. The Hygenist was also very good and explained a great deal about the process and results. Very happy with both
