Abstract

Background: The various advantages of crown materials produced using three-dimensional (3D) printers have increased their use in restorative and prosthetic dentistry in recent years. Accordingly, their optical and mechanical properties have become more important.

Objectives: To evaluate the mechanical, surface and optical properties of crown materials produced with 3D printing and computer-aided design (CAD)/computer-aided manufacturing (CAM), which has recently been used frequently in the clinic.

Material and methods: The 3-point bending test was used to evaluate the mechanical properties of 2 different crown materials produced with 3D printing (Permanent Crown and VarseoSmile Crown Plus) and a crown material produced using CAD/CAM (Vita Enamic). After the initial color and surface roughness measurements were made, the specimens were immersed in 4 different solutions.

Results: The most translucent material was VarseoSmile Crown Plus (p < 0.05). In all specimens, coffee caused the most discoloration (p < 0.05). The effects of the solutions on the roughness were mostly observed in Permanent Crown specimens (p < 0.05). Vita Enamic showed the highest statistically significant values in terms of flexural strength (p < 0.05).

Conclusions: The stereolithographic technique among the materials produced by 3D printing can be recommended for use in restorations due to its higher flexural strength.

评估三维打印技术生产的冠状材料的光学和机械性能。

背景：近年来，利用三维（3D）打印机生产的牙冠材料具有各种优点，因此在牙科修复和假牙制作中的应用越来越广泛。因此，它们的光学和机械性能也变得越来越重要：评估最近在临床上频繁使用的三维打印和计算机辅助设计（CAD）/计算机辅助制造（CAM）技术生产的牙冠材料的机械、表面和光学特性：采用三点弯曲试验来评估用三维打印技术制作的两种不同牙冠材料（Permanent Crown和VarseoSmile Crown Plus）和用计算机辅助设计/计算机辅助制造技术制作的一种牙冠材料（Vita Enamic）的机械性能。在对颜色和表面粗糙度进行初步测量后，将试样浸入 4 种不同的溶液中：结果：最透亮的材料是 VarseoSmile Crown Plus（p < 0.05）。在所有试样中，咖啡导致的褪色最多（p < 0.05）。溶液对粗糙度的影响主要体现在永久冠试样上（p < 0.05）。在抗弯强度方面，Vita Enamic 显示出最高的统计意义值（p < 0.05）：在 3D 打印技术生产的材料中，立体光刻技术因其较高的抗弯强度而被推荐用于修复体中。

期刊介绍： Advances in Clinical and Experimental Medicine has been published by the Wroclaw Medical University since 1992. Establishing the medical journal was the idea of Prof. Bogumił Halawa, Chair of the Department of Cardiology, and was fully supported by the Rector of Wroclaw Medical University, Prof. Zbigniew Knapik. Prof. Halawa was also the first editor-in-chief, between 1992-1997. The journal, then entitled "Postępy Medycyny Klinicznej i Doświadczalnej", appeared quarterly. Prof. Leszek Paradowski was editor-in-chief from 1997-1999. In 1998 he initiated alterations in the profile and cover design of the journal which were accepted by the Editorial Board. The title was changed to Advances in Clinical and Experimental Medicine. Articles in English were welcomed. A number of outstanding representatives of medical science from Poland and abroad were invited to participate in the newly established International Editorial Staff. Prof. Antonina Harłozińska-Szmyrka was editor-in-chief in years 2000-2005, in years 2006-2007 once again prof. Leszek Paradowski and prof. Maria Podolak-Dawidziak was editor-in-chief in years 2008-2016. Since 2017 the editor-in chief is prof. Maciej Bagłaj. Since July 2005, original papers have been published only in English. Case reports are no longer accepted. The manuscripts are reviewed by two independent reviewers and a statistical reviewer, and English texts are proofread by a native speaker. The journal has been indexed in several databases: Scopus, Ulrich’sTM International Periodicals Directory, Index Copernicus and since 2007 in Thomson Reuters databases: Science Citation Index Expanded i Journal Citation Reports/Science Edition. In 2010 the journal obtained Impact Factor which is now 1.179 pts. Articles published in the journal are worth 15 points among Polish journals according to the Polish Committee for Scientific Research and 169.43 points according to the Index Copernicus. Since November 7, 2012, Advances in Clinical and Experimental Medicine has been indexed and included in National Library of Medicine’s MEDLINE database. English abstracts printed in the journal are included and searchable using PubMed http://www.ncbi.nlm.nih.gov/pubmed.
