When a tooth is removed from the mouth, the surrounding bone that holds the tooth in place will diminish in height and width and volume. This may have an effect on the immediate and final appearance of the gum tissue in this area and possibly the surrounding teeth as well.
The larger the width of bone or the height of the bone, the wider and longer implant can be. A wider and longer implant increases implant stability and thus success. We asses the bone height and width by taking digital radiographs or by taking a CT Scan.
A CT Scan produces a three-dimensional analysis of the bone allowing us not only to understand the height and width of bone but also know what other underlying anatomical structures may be nearby that we may need to be aware of. It allows us to accurately plan the position and size of the impacts as well.
For the upper jaw, the bone height may be limited by the presence of the sinus. In this case it is easily possible to increase the bone height by performing a Sinus Graft procedure or Sinus Lift procedure. Sinus Graft procedure is the treatment of choice when the extra volume and height of bone is more than a few millimetres.
Sinus graft is a minor procedure where a small window, about 1cm diameter, through which the sinus lining is gently lifted and bone placed. A healing period of 3 - 6 months is advocate prior to the placement of the implant.
Sinus lift procedure is carried out, by using ostoetomes ( special hand use implant instruments with a blunt end), where we lift the sinus floor up by a few millimetres allowing for an increase size of height of the implant.
In the lower jaw, we have to ensure that there is adequate bone above the nerve.
Most often, even if bone is initially inadequate, bone graft procedures allow us to add extra volume of bone and thus not hinder the placement of implants. Alternatively, very specific custom made fin or blade implants can be used.
If thinking of having implants and if there is a reduced width of bone to place an implant then a simple Bone Graft can be carried out using:
- a. bone graft from any aspect of the mouth e.g: the tuberosity region
- b. Irradiated human or bovine bone.
- c. Artificial bone.
- d. Combination of the above.

I have been visiting Perfect Smile for couple years for on going treatment including implants and Veneers. I developed an abscess over Christmas Holiday with a fever where I passed out on my kitchen floor. I did email Gurs not expecting him to reply within an hour or so (especially it being the festive season) Gurs suggested I should get to the hospital to get antibiotics and emergency dentist next day. Gurs kept in touch daily to check on my welfare. A week later I was well enough to travel from Norfolk to Perfect Smile. The following week Negan did root canal. The team are first class, who make you welcome and always asking if I would like a drink. The treatment has cost me thousands. Money well spent!! I now have The Perfect Smile.

I live in London so it was no problem visiting them at Harley Street, I was a bit nervous when I walked in but it all went fine and I now have no more gaps in my teeth, many thanks
