Exploring the Barriers to the Advancement of 3D Printing Technology

3D printing technology is suitable for application in advancing digitization dentistry. However, the use of this dental field not as widespread expected. The study discusses barriers to First, Fuzzy Delphi was used conduct in-depth interviews with experts explore what prevent advancement Second, decision-making and trial assessment laboratory (DEMATEL) identify cause-and-effect relationship among barriers. Because DEMATEL relies on expert system, often have different experiences backgrounds, so judgment results are uncertain inconsistent. Therefore, proposes using a rough-Z-number integrate opinions experts, which can effectively overcome problems inconsistency uncertainty. After analyzing results, we found that “lack standard infrastructure” most important barrier dentistry, provides improvement strategies based results. put forward countermeasures promotion will make development more effective.
