Cylindrical dental implants coated with cancellous structured titanium (CSTi) were studied in a dog model. CSTi-2-coated and hydroxyapatite-coated (HA) implants were placed in 8 mongrel dogs. The porosity of the CSTi-2 coating was 9% less than that of the previously studied CSTi-1, resulting in greatly improved mechanical strength and cosmetic appearance. A(More)
The in vivo integration strength and degree of bone apposition were compared for oral endosseous implants with different plasma-sprayed hydroxylapatite (HA) coatings. Pullout strength measurements and histological analysis were used to compare two different commercially available coating from the same manufacturer. One coating does not receive a(More)
A novel pressurized hydrothermal post-plasma-spray process, referred to as MP-1, has been developed to convert the crystalline non-HA and amorphous components of plasma-sprayed hydroxylapatite coating back into crystalline HA. No detrimental effects are observed on the strength of either the base metal or the coating. X-ray diffraction (XRD) and FTIR(More)
Algorithms for modeling static vowel shapes using a half-sample delay Kelly-Lochbaum model are described, so that the total tract length is no longer limited to an integer multiple of the segment length, but can take on any continuous value. Fractional-delay filters are used for modeling lengthening of lips, lowering of the larynx and lengthening of an(More)
A novel pressurized hydrothermal post-plasma-spray process has been developed to convert the crystalline non-HA and amorphous components of plasma-sprayed hydroxylapatite coatings back into crystalline HA. The process, known commercially as MP-1, was used to produce coatings comprising approximately 96% crystalline HA. The in vitro solubility of the coating(More)
