n Journal of Minimum Intervention in Dentistry - What is the clinical longevity of lithium disilicate ceramics? [October 31, 2018] - preliminary systematic literature searches

Volume 13 Number 2
  • ISSN : 1998-801X


Search result: 6 trials and 6 systematic reviews were found.

Clinical outcomes: The results suggest that:

(i) for lithium disilicate single crowns, the existing evidence indicates excellent short-term survival rates, but the evidence for medium-term survival is limited;
(ii) for lithium disilicate fixed dental prostheses, the evidence for short-term survival is fair, although limited, but the evidence for medium-term survival is not promising;
(iii) there is contradicting evidence whether the majority of failures occurs in the posterior or anterior region;
(iv) the marginal precision for lithium disilicate restorations compared to conventional metal-ceramic and zirconium dioxide crowns is lower;
(v) that prosthetic material selection has no influence on mid- and long-term survival of implants restored with single crowns and fixed partial dentures or on prosthetic survival rates.

State of evidence and recommendations: The quality of the existing evidence requires further assessment.

[‘Preliminary Systematic Literature Searches’ are based on SYSTEM’s periodic systematic searches of the dental literature and provide first overviews over existing clinical evidence but are limited in the number of databases searched, as well as the assessment of precision and internal validity of results and thus do not replace the need for a full systematic review report to the topic]
