A total of adhesively cemented ICRs in 34 participants aged 6 to 50 years and treated between and were evaluated for survival and clinical quality. All were individually layered restorations fabricated from laboratory sculptable composites by a specialized dental technician. Two calibrated independent investigators examined and graded each restoration as success, survival with repair, or failure based on the FDI criteria.
The marginal quality and gap width of the restorations were analyzed by scanning electron microscopy. Success and functional survival rates were calculated using the Kaplan—Meier method. The median age at treatment was The median service time of the restorations was 5. The success rates at 1, 5, and 10 years were The mean marginal gap width was ICRs are suitable for minimally invasive restoration of large tooth structure defects in the developing dentition of children and adolescents and for long-term temporary restoration of the adult dentition.
Keywords: adolescent dentition, adult dentition, clinical quality parameters, indirect composite restorations, qualitative margin analysis, survival. The demand for indirect composite restorations ICRs has increased significantly in recent years.
Although their short-term success and survival rates are slightly lower than those of silicate ceramics, some studies have reported comparable rates. All-ceramic restorations are more wear- and fracture-resistant 1 , 6 , 63 and less prone to plaque retention than ICRs. In addition, composites can be integrated into orthodontic treatment regimens with relative ease, and composite surfaces are more conducive to adhesive bonding of orthodontic elements than ceramic surfaces.
