Surface Treatment for dental implants and pacemakers Comco's micro-abrasive blasting equipment provides surface treatment solutions for the manufacture of medical parts It is used to roughen the smooth surface finish on the threaded portion of dental implants. Roughening this area of the implant increases the surface area for the tissue to take root, improving the bond. The ability to promote this tissue in-growth is a critical component to the implant's success. Microblasting is also used to improve the surface finish of pacemaker cans. Using glass beads as an abrasive, Comco's microblasting equipment quickly removes scratches and marks, leaving an attractive satin finish on the can. Comco offers sample part testing to determine the most efficient microblasting method for any application. Our engineers have the expertise and complete test facilities to determine if a microabrasive blasting process can be used to improve production efficiency and product quality.
