Objective Bone marrow defects of the jaw (BMDJ) surrounding dental implants. in combination with impaired bone-to-implant contact (BIC). are difficult to detect in X-rays. This study evaluated BMDJ surrounding titanium (Ti-Impl) and ceramic (Cer-Impl) dental implants and incomplete BIC using a new trans-alveolar ultrasonography device (TAU) with numerical scaling for BIC. https://mabelandfoxs.shop/product-category/white-noise-machine/
