Abstract: The unclear clinical outcomes of two different zero‐profile implants with different number of screws in hybrid surgery restricts the choice of patient‐specific implants. This study aims to compare two different implants on its postoperative subsidence,… read more here.

Abstract: In this paper, we completely classify, up to homeomorphism, the orientable and nonorientable orbifolds which have a Heegaard decomposition consisting of orbifold handlebodies with Euler number zero. In addition we compute their fundamental groups. read more here.
