    Design and biomechanical evaluation of a cementable endosteal blade implant (1976)

    Notes: A cementable endosteal blade implant has been developed and evaluated. Inherent in the design are the following factors: minimization of stress concentrators, ease of implantation, and high resistance to loosening. Other potential advantages of this design as compared with conventional endosteal blade implants include reduced hazards of postoperative infection and reduced likelihood of metallic corrosion.Six conventional endosteal implants and six cementable implants were installed in steer mandibles using standard dental surgical techniques and Simplexbrand methyl methacrylate bone cement. They were loaded in uniaxial compression at a loading rate of 0.0122 in./min. The stiffness (S), deformation at 900-lb load (D900), proportional limit (PL), and load at 0.04 in. deformation (L0.04) were calculated for each test.The cementable design showed a twofold increase in stiffness, only 17% of the deformation at 900 lb, more than twice the proportional limit, and at least twice the load at 0.04 in. deformation when compared with similar values for the conventional endosteal implants.This study reveals that, in addition to being unstable in bone, conventional endosteal implants are also unstable when used with acrylic bone cement. The new design should eliminate most of the problems associated with endosteal blade implantation.

    Notes: The extensive use of plastics for insulation and building materials has created interest in the possible toxicity of their combustion products. Three poly(vinyl chloride) homopolymers, a vinyl chloride-vinyl acetate copolymer, and formulations of two of the homopolymers and the copolymer have been examined to determine the composition and toxicity of their combustion products. Differential thermal analysis and thermal gravimetric analysis were used to study the breakdown process which occurred in several steps, the largest and first being the release of hydrogen chloride from the polymer at about 300°C. Approximately 50 products of combustion were then determined qualitatively by using either infrared spectroscopy or a combination of gas chromatography and mass spectroscopy. Quantitative analyses were carried out on 22 of the combustion products, and quantitative changes with varying air supply, temperature, and heating rate were determined. A comparison of the products of the polymers and their formulations is given.

    Notes: Comparisons were made of changes in molecular weight and in tensile strength of regenerated cellulose after exposure to 40% KOH at 90°C., for varying lengths of time. In the absence of air, both parameters decreased in a fairly consistent manner. In the presence of air, an initial steeper drop was followed by an irregular up-and-down pattern. The theory is advanced that the increase in tensile strength was caused by increased crystallinity.

    Effect of structure on temperature stability and solubility of polyester-urethanesPresented before the Division of Polymer Chemistry at the 141st National Meeting of the American Chemical Society, Washington, D.C., March, 1962. (1963)

    Notes: The composition of crosslinked polyester-urethanes has been varied by adjusting the ratio of ester to urethane groups. The crosslinking density of these materials has been varied by changes in the polyester functionality. The polyester-urethanes have been subjected to solvent extraction, wherein it was found that at high crosslinking densities, the solubility of the polymers is unaffected by the ester-urethane ratio. At low crosslinking densities, solubility increases slightly with increasing urethane concentration. The solubility was also found to increase with decreasing crosslinking density. Data obtained from isothermal heat aging and thermogravimetric analysis, both carried out in air and in inert atmosphere, indicate that thermal stability increases with increasing ester/urethane ratio and is independent of crosslinking density where the ester/urethane ratio is held constant. In addition, data obtained from heat aging and thermogravimetric analysis have indicated that decomposition of the samples occurs as rapidly in inert atmosphere as in air, indicating that the decomposition occurs chiefly by a nonoxidative mechanism.

    Notes: The corrosion of steel by nitrile elastomer oil seals prompted a laboratory study of the corrosivity of numerous compounding ingredients and nitrile polymers. Groups of materials studied in this investigation were plasticizers, antioxidants, black fillers, nonblack fillers, curing systems, and base polymers. A corrosion test procedure utilizing a benchtype corrosion chamber was developed, and a corrosion rating system was established. All materials were rated according to their corrosivity under conditions of 100% R. H., and 100°F. for 96 hr. From these data it was possible to formulate several noncorrosive seal compounds without the use of corrosion inhibitors.
