    Chemical and mechanical behavior of bioglass-coated alumina (1976)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Biomedical Materials Research 10 (1976), S. 503-509

    Notes: Procedures for applying nonporous bioglass coatings to fully dense, high-purity alumina are described. By altering firing temperatures and number of coatings, the rate of surface reactivity of the coated alumina can be varied. Bonding of bioglass-coated alumina to rat bones is reported as early as three weeks.

    Evaluation of a bioglass-coated Al2O3 total hip prosthesis in sheep (1976)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Biomedical Materials Research 10 (1976), S. 511-518

    Notes: A bioglass-coated fully dense alumina total hip was evaluated in sheep without using polymer bone “cement.” After 3 months following surgery, both the acetabular cup and femoral stem component were firmly attached to bone. Histologic and radiographic analysis of the bone-implant interface showed regions of woven and even lamellar bone formation where high load transmission occurred. In regions of low loading or poor fit, a pseudosynovial fibrous lining was present.

    Analysis of bioglass fixation of hip prostheses (1977)
    Hoboken, NJ : Wiley-Blackwell
    Journal of Biomedical Materials Research 11 (1977), S. 267-282

    Topics: Medicine , Technology
    Notes: The analysis of the bonding interface between hip prostheses and bone after functional use in animals was carried out. Scanning electron microscopy (SEM) with energy dispersive analysis (EDX), and Auger electron spectroscopy were used to evaluate the bonding interface. Various methods of postsacrifice sample preparation were used to evaluate the effect of such different methods on the analysis of the bonding interface. Comparison of the results with several rat tibia implant experiments is also presented.

    Use of fracture mechanics theory in lifetime predictions for alumina and bioglass-coated alumina (1979)
    Hoboken, NJ : Wiley-Blackwell

    Notes: The fatigue behavior of alumina and bioglass-coated alumina was determined in air and biological test environments by the dynamic fatigue test technique in which strength is measured as a function of stressing rate. The good correlation found between the test data and fracture mechanics theory indicates that fatigue failure is controlled by the slow crack growth of preexisting flaws and that fracture mechanics theory can be used in making failure predictions for alumina and bioglass-coated alumina in biological environments. Thus, it is believed that lifetime predictions can be made for ceramic implants on the basis of short-term test data utilizing fracture mechanics principles.
