Polymer blocks homogeneity concerning the speed of sound for in vitro studies in implant dentistry

Abstract

Abstract Dentistry implants methods are recursively enhancing the image localisation approach to improve patient point of intercession accuracy. Previous planning of the surgical act is on the cut edge of the technology. Materials that mimic the implant house, i.e., the maxillary bone, have been developed and improved material technology. Standard non-invasive and non-ionising radiation technologies are relevant tools to that approach. Ultrasound imaging techniques play a prominent role in that matter. Nevertheless, recent polymer materials specially developed to help the pre-implant studies had not been evaluated about their homogeneity of ultrasound parameters. Two specially developed polymer materials have their speed of sound analysed in a metrologically based methodology. At 1 MHz, a set of 10 blocks were considered statistically equivalent, unless one specimen. The speed of sound was 1020 m s−1 (expanded uncertainty for p = 0.95 equals 22 m s−1) and 1676 m s−1 (U0.95 = 10 m s−1). The ultrasound homogeneity is a vital outcome of the reliability of those materials used in dentistry implant pre-clinical studies.
