SUMARRY Clinical relevance and aim: The goal of this systematic review is to determine the durability of chairside fabricated lithium disilicate single crowns (made with IPS e.max CAD) and laboratory fabricated heat-pressed LD single crowns. That is done by comparing survival rates of CAD/CAM fabricated and conventional laboratory fabricated full lithium disilicate crowns (IPS e.max Press and Empress II) after minimum follow up time of 2 years, up to 12 years. Materials and methods: Three electronic databases (PubMed/MEDLINE; Springer and Science Direct) were used to conduct evaluation of in vivo studies using different combination of keywords: CAD/CAM and Complications and Dentistry; Chair side and Lithium Disilicate crowns; CAD/CAM and Lithium Disilicate; CAD/CAM & Prosthodontics; Lithium disilicate crown and Failure; Lithium disilicate and Survival rate The search was performed in accordance with PRISMA statement and articles were selected according to predetermined inclusion criteria. Results: Fourteen studies were selected for the final analysis from an initial amount of 5770. Overall chairside CAD/CAM fabricated restorations proved to be durable in the long run, with a 10 year follow up survival rate of 83.5%, compared to 87.1% for Empress II and 80% for e.max Press lithium disilicate crowns. Conclusion: The chairside lithium disilicate CAD/CAM restorations had a limited amount of research and small sample size, however it can be recommended for medium-term use as its durability did not differ significantly from laboratory made restorations. Long term results were better for heat pressed restorations but had a large bias due to loss of patients to follow up.
