Not all HA Coating Implants are the same.

Hydroxyapatite (HA) is the same material as the alveolar bone that meets the implant and is mainly used to boost bone growth.
Therefore, the use of an HA-surface-treated implant will result in a faster and more rigid bonding between the bone and the implant. HA-surface-treated implants are suitable for the cases of weak bones, maxillary sinus, or difficult surgeries requiring immediate placement after tooth extraction. However, HA is a material very difficult to maintain the ingredients during the course processing, and a huge difference occurs depending on the processing technical skills of the manufacturer.For this reason, processing technical skills, such as high content of pure HA ingredient after processing, surface treatment with uniform thickness, high strength of bonding with Base Metal (Titanium6Al-4V ELI Alloy), are much more important than raw material itself.

ZIMMER BIOMET MP-1® is the only HA treatment technology capable of maintaining more than 97% of pure HA content through the Pressurized Hydrothermal Post Plasma Spray Process (A Way for hydrothermal treatment under the state of maintaining constant air pressure after the Plasma Spray treatment) HA is a material very difficult to maintain the content during the course of processing, and it has been a long R&D challenge for many manufacturers to develop a processing method that can maintain the purity of HA even after the processing. ZIMMER BIOMET is the pioneer of HA Coating Implant, and it has developed MP-1® manufacturing technology to maintain the pure HA content of the pre-processing through the over 30 years of research and clinical trial experiences. MP-1® maintains more than 97% pure HA content to increase the bond strength of Base Metal (Titanium Alloy) and HA, enabling faster and more stable osseointegration. Because of the large differences in joint strength and solubility, depending on the manufacturing method and technical ability of each manufacturer, even the same HA- surface-treated implants will have different results. Now, please make sure to check for the MP-1® mark when selecting HA-Coating Implant.

The method and technology of HA Coating differ from manufacturer to manufacturer, and clinical results are also bound to be different accordingly. The low content of Crystalline HA means the change in the content of the pure HA due to high heat during the coating process. In addition to Crystalline HA, if the ratio of amorphous calcium phosphate is high, problems of HA dropout and dissolution may occur. On the other hand, if the content of Crystalline HA is high, there is no dropout nor dissolution of HA in the mouth. Please experience the difference between 97% and 38% of Crystalline yourself.
