Objective
- Preparation of bioactive controlled resorbable Hydroxylapatite (HAP) layers
Method
- Dip coating of inlay materials with nanodispersed sol with nonstoiciometric HAP
(Ca5(PO4)3OH) and densification at T<600°C
Results
- bioactive HAP layers
- layer thickness between 0.5 and 5 µm
- adhesive strength:up to 20 MPa
- adjustable Ca/P ratio:1.59 - 1.80
|
Applications
- Coating of mechanically stressed orthopedic and dental implants to improve the
biocompatibility
Advantages
- variable resorption rate
- complete resorption
- reduced crack formation
- simple coating technology
- Coating of porous metal substrates (infiltration) is possible
