Sinuslifting & Bone grafting

Sinus elevation

Bone grafting is necessary when there is not enough quality and quantity of bone material surrounding either the implant area or that of the surviving roots. Bone reduction occurs naturally over time and is the reason why implants should be placed very soon after extraction.

What causes bone loss?

Whenever a tooth is lost or extracted a considerable amount of the bone that once surrounded the remaining root portion may disappear. This loss can be particularly rapid during the first few months and is described as ‘bone resorption’. Although the rate and amount of bone resorption is highly variable between individuals, it will always occur to some extent, unless specific care is taken to reduce its effects. Sometimes, the simplest measure to minimise bone loss after an extraction is to place the implant immediately (if there is no infection) or within the first few months.

What is Bio-Oss?

Bio-Oss is a safe, effective bone graft material. Under other electron microscope, Bio-Oss looks very similar to human bone and is highly successful in helping new bone to form. Bio-Oss acts as a framework onto which bone forming cells and blood vessels travel along the Bio-Oss framework, healthy new bone is formed and the defect is repaired. It is prepared from specially processed bovine sources. Every batch of Bio-Oss goes through highly controlled processing and sterilization procedures which remove all impurities. At the end of these procedure, every batch of Bio-Oss must pass rigorous sterility and purity tests, assuring total safety of the materials.

Sinus elevation

This procedure involves elevating the sinus membrane and placing the Bio Oss bone graft onto the sinus floor, allowing implants to be placed in the back part of the upper jaw. Premature loss of upper back teeth results in a down growth of the maxillary sinus floor. So that implants of adequate length may be placed, the floor of the sinus is elevated and supported by bone graft material. This procedure has been performed successfully for over two decades now and is considered an accepted and predictable method of bone grafting.

Dear Dr Kaman, I must write to you saying what a fantastic Job you made of my teeth bottom jaw and lower jaw. Dr Zsuzsanna was just marvelous. The top denture feels just like my own teeth and very comfortable. Very little food gets trapped underneath and I only take my dentures out to clean after I have eaten. The bottom denture is OK but not as good as the top. So if in the future I can have bone grafting in my bottom Jaw so that I can have implants placed this is what I would like to do. Please let me know when this would be possible.

Best regards,

J. & G. I.
