Abstract

INTRODUCTION

Oral rehabilitation with overdenture on implants of upper jaw must be taken into consideration a variety of anatomical and biomechanical issues. It is possible to provide for rehabilitation with two or more implants, in different positions, solidarizing them with a bar.

MATERIALS & METHODS: The present study involved a patient rehabilitated with 4 Xive implants (Friadent GmbH, Mannheim, Germany) solidarized with a titanium bar crafted with CAD-CAM technology for maximal comfort, precision and structural lightness.

RESULTS & DISCUSSION: The follow-up was 54 months, with an implant survival of 100%. Based on our clinical evidence, bars engineered with CAD-CAM technology are promising in terms of precision and comfort despite higher costs.

摘要

引言

在上颌种植体上进行覆盖义齿修复时，必须考虑多种解剖学和生物力学问题。可以使用两个或更多处于不同位置的种植体进行修复，并通过杆将它们连接成一体。

材料与方法

本研究涉及一名患者，该患者使用4颗Xive种植体（德国曼海姆的Friadent GmbH公司生产）进行修复，这些种植体通过采用CAD-CAM技术制作的钛杆连接成一体，以实现最大程度的舒适度、精确性和结构轻盈性。

结果与讨论

随访时间为54个月，种植体存活率为100%。根据我们的临床证据，尽管成本较高，但采用CAD-CAM技术制造的杆在精确性和舒适度方面很有前景。
