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.

Kate and Rebecca are both excellent in their specialisms; I always feel that I’m in safe, caring hands (and I’m a relatively nervous patient!). Support staff all good too.

I received the high quality experience at Durban that is the norm for this practice.Christine, hygienist, is exceptional in her care for the client, always checking that all is well throughout the treatment with special attention to comfort, very necessary for my particular needs.

I am a nervous patient after experiencing a lot of pain at dentists over the years but I was listened to and was allowed to play my music throughout which kept me calm ☺️

From reception to Hygienist and Dentist my care was 5*. I felt very well cared for and received a high standard of care.

Reception staff polite and friendly. Ashley Sim (dentist) was thorough, thoughtful, considerate. He gave me confidence in that if he thought I didn't need a treatment, or would not benefit from it, he said so. Therefore, I am confident if he says I need treatment, then I do.

I had reported pain in a molar to my dentist at the last visit and he said the old filling had to be removed as no longer viable. This apt he removed the amalgam filling, cleaned the area removing a small amount of decay and refilled. He took an enormous amount of care to get the bite right. Amazingly, the whole procedure didn't hurt one bit. Will not go anywhere else.

22nd May 2026

Well organised.

21st May 2026

Ashley Sim listened to my concerns and understood the circumstances giving rise to the appointment. Ashley checked the area in question and offered to take an x-ray should it put my mind at rest.We discussed the preferred way forward, given other medical considerations, with the option being available to undertake any interim treatment should the need arise.I never doubt that Ashley will listen and explain.
