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.

Since being referred to Ashley Sim for the making of a denture, he has been super efficient and kindness itself. Dentists are not my favourite people due to past experiences and all the staff at Durbans have been very understanding.

I can't thank Dr Ruth, Dental Nurse EJ and Hygienist Anda enough for their kindness, care and compassion, following my recent extensive dental treatment. I can now smile with confidence. I would highly recommend each of them, and I feel I have found the perfect practice for me. Thank you so much.

Saw Dr Ruth and dental nurse EJ, fantastic and calm service. Kids felt relaxed and well looked after. Their patient is their main priority and they are focussed on well being.

How they look after you and the time they have for you, also how at ease they make me feel. Never rushing me out the door and always happy to answer all my questions.

Seen two other dentists previously at other practices about this problem and they failed to treat it appropriately. I have been in discomfort for around 18 months. It has now been solved by your practice.

I have an irrational fear of needles and drills and so trips to the dentist for me are highly traumatic. The team at Durban Dental are incredibly understanding, and make it a lot more bearable.
