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.
