Dr. Hiura implanted replacement bone material, with growth hormone, into my upper right jaw under 4 teeth. He and his assistant were gentle, competent, and a joy to work with. The operation was a complete success, restoring my bone mass to over 80% of expected (it had been at 50%). The operation itself was painless. Recovery was somewhat painful, but dr. Hiura's office prepared me well, and provided appropriate treatment. His office has been very professional and handled insurance, followup visits, and billing well.
