Design: A triple-armed, double-blind randomized controlled trial with cross-over design investigated patient-reported satisfaction and objective dental evaluation of a 3-unit, monolithic zirconium dioxide (ZrO2), implant-supported fixed dental prosthesis (iFDP) fabricated with 2 completely digital workflows and 1 mixed analog-digital workflow.
Case Selection: Participants enrolled required rehabilitation of 2 dental implants in posterior region of either of the arches with a 3-unit, ZrO2 iFDP. A total of 20 participants received the 3 types of ZrO2, iFDP fabricated by 3 different methods.

In recent years, CAD/CAM techniques have been developed to produce retainers with high precision and tension-free fit. The aim of this retrospective study was to evaluate the suitability of a semi-industrial retainer manufacturing process (office-based construction, external laboratory manufacturing) in terms of positioning accuracy and post-treatment changes.

The heating oil circuit plays an essential role in the heating calendering roller for the lithium battery pole piece. To achieve the optimization of the heating oil circuit, a fluid-thermal-structural coupling method and a multi-objective optimization procedure are proposed to obtain the optimal solution. A fluid-thermal-structural coupling flowchart based on the numerical modeling for the calendering roller temperature distribution is created to automate the analysis processes in the optimization iteration.
