Longevity of fiber-reinforced composite fixed partial dentures (FRC FPD)-Systematic review.

OBJECTIVES

to assess FRC FPDs longevity through systematically reviewing contemporary clinical evidence. Population investigated comprised patients requiring replacement of a single missing anterior/posterior tooth. Intervention was FRC FPDs. No control/comparison selected. Outcome was longevity of FRC FPDs. The focus question was: 'What is the longevity of FRC FPDs used to replace one anterior or posterior tooth in patients?'

DATA

Randomised, non-randomised, controlled, prospective and retrospective clinical studies were included. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses were applied. The Overall Strength of Clinical Recommendation (OSCR) was assessed using the Strength of Recommendation Taxonomy system. Survival of FPDs was assessed using the Kaplan-Meier method. Analysis of FPD-survival according to location and occurrence of different failures was performed using Logrank and Chi-square testing.

SOURCES

PubMed, MEDLINE, and Web of Science databases were searched between January 2007 and December 2015.

STUDY SELECTION

Nine studies were included, involving placement of 592 FRC FPDs in 463 patients. Follow-up periods ranged between 2 months and 8 years. Kaplan-Meier overall survival probability was 94.5% (95%C.I: 92.5%-96.5%) at 4.8 years. There was no significant difference in survival probability of anterior versus posterior FRC FPDs (P=0.278). Veneering material fracture/delamination occurred significantly more than other types of failures (Ps<0.05). A meta-analysis could not be performed. OSCR was moderate.

CONCLUSIONS

FRC FPDs demonstrated high overall survival with predictable performance outcomes. However, long-term performance remains unclear.

CLINICAL SIGNIFICANCE

FRC FPDs are viable medium-term management alternatives for replacing single anterior or posterior teeth in patients.
