10 years after sinus floor augmentation


I sometimes encounter patients who don’t have enough bone in upper molar teeth missing area for placing dental implants. I learned skills of sinus floor augmentation, surgery of growing new bone in sinus for upcoming dental implants surgery, at University of Michigan in 2002. The reason for going abroad was that I could practice the skills using cadavers in US, which has been prohibited in Japan. Since then, I have overcome the difficulties in placing implants in upper molar. This is one of such cases, CT scan images after 10 years showing stable condition. The more I learn, the more I can contribute.

Dental implants: 10 years after sinus floor elevation

 My friend’s back teeth were lost due to decay. (He is a brain surgeon.) To carry out dental implants for him, I had to learn the way to generate bone in his sinus. An egg is a good material for practicing sinus floor elevation. I learned the technique in Michigan 10 years ago. Dentists who had the skill in Japan were rare in those days. Whenever I have patients who need the surgery, I make it a rule to practice with eggs before actual performance.
