Clinical Performance Of Lithium Disilicate Restorations In The Last 10 Years. Narrative Review.
Objectives: Among the aesthetic ceramic materials, Lithium Disilicate has shown on the last decade an exponential growth, due to its excellent mechanic and aesthetic properties. The aim of this review is to describe the clinical performance and the fulfilment of aesthetic, mechanic and biological properties together with the survival rate of the material on the last 10 years.
Methods: The information research was made on four databases; Pubmed, Ebsco, Trip Database and Scopus. The last guideline for clinical performance evaluation developed by the FDI was used as the analysis and comparison base model. A critical review of the literature has been made which incorporated: quality report, level of evidence, grade of recommendation, bias risk and ethical aspect of each study included.
Results: A total of 24 studies fulfilled the selection criteria, within which only one systematic review stands out till the date. Nevertheless most of the articles were observational. Between the relevant results this study exhibit 100% caries free restorations, decrease marginal adaptation and a rise in retention loss on the first 2 years for the partial restorations. Single crowns had a superior performance in anatomical shape, pulpal sensitivity, caries lesions, periodontal response and marginal adaptation than metal porcelain restorations. Three unit bridges present better aesthetic parameters than conventional restorations, however they display more biological complications and on the first two years up to 50% fracture. The minimum survival rate obtained was 95.46% for crowns, 97% in partial restoration and 62.7% in three unit bridges.
Conclusions: Despite the extensive analysis, to this date, new studies with better methodology and design are required for a properly clinical performance evaluation of the Lithium Disilicate as restorative material.
