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!

Caring, professional service.

11th June 2025

I am a nervous patient but dentist totally put me at my ease. He explained everything that he was doing.

11th June 2025

Credit is due for the personal attention, professional service and good humour from Sarah and Holly in the first appointment and for Tracey and Casey in the second appointment. They were of a high order to their personal credit. As I said to Sarah and Tracey while they deserve credit so do Holly and Casey supporting them. They concurred!

11th June 2025

Great staff and service.

11th June 2025

Attention and care cannot be faulted. Compared to my previous experiences at a previous dentist, though less costly, they were poor. Happy to pay the price for the exceptional care at Mayhill on offer.

10th June 2025

My dentist is professional, has time to discuss and explain all options, he gives great feedback is very encouraging on what I need to do and remember ( or does his homework before I arrive ) as Iv had a few problems they have been amazing at working through which makes me feel valued.

10th June 2025

It felt as if nothing was too much trouble for everyone looking after me that morning. The receptionists, dental nurses and both of the dentists. Absolutely wonderful care and loving attention.

7th June 2025

I have built a wonderful rapport with the team at Mayhill. They are extremely knowledgeable, and explain everything very clearly. In the two years I've been there, I have completely transformed my daily brushing routine with the amazing support of Tracy the hygienist, and completely overcome my fear of dental treatment. I was even able to have a tooth extraction performed without sedation, which I never dreamt would be possible, since I was such a nervous patient when I started. Transfering to Mayhill was one of the best decisions I have ever made for my health and wellbeing

Ability to deal kindly with an anxious patient like me

3rd June 2025

I recently became a patient at Mayhill after suffering with excruciating toothache that in the end required an extraction. I was originally given antibiotics but unfortunately this didn’t work so booked an emergency appointment followed by an extraction. The care received throughout this process was fantastic. I recently returned to see the hygienist and again the experience was positive. I’m very happy with the service throughout and will continue to use the dentist.

3rd June 2025

Reception staff very friendly, and Jason explained everything as we went along.

2nd June 2025
