Apatite products, the mainstay products of HOYA's New ceramics division, are
used mainly in the fields of orthopedics, brain surgery and dentistry as
prosthetic fillers for bone defects. APACERAM, one of HOYA's apatite products,
boasts the overwhelming top share in the ceramic artificial bone market. It is
made of hydroxyapatite, a chemical compound that is virtually the same as the
constituents of human bone. Hydroxyapatite implantation is safe, and in fact,
over time, the implant is partially resorbed and replaced by natural bone, as it
becomes part of the body.
HOYA also launched a solid-type prosthetic filler, SUPERPORE™, in 2010.
The Company also launched a paste-type prosthetic filler, BIOPEX®
ADVANCE, which reaches maximum strength in just 12 hours after surgery.
This gained kudos for greatly improving the quality of life of patients, by
enabling them to rise up the day after surgery.
In 2012, HOYA could gain a foothold through entering the market for metallic
implants, which has a size of 120 billion yen. The company is determined to
focus its efforts on the development of new products combining ceramics and
metals.
