Analyze and quantify the residual monomer elution of nine conventional and CAD/CAM (computer-aided design/computer-aided manufacturing) dental polymers during artificial aging.
Materials and methods
A total of 360 square–shaped specimens (14 × 12 × 2 ± 0.05 mm) were fabricated from eight CAD/CAM polymer blanks (
n
= 40): Avadent Base material, Avadent Teeth material, PMMA Multi blank, PMMA Mono blank, Temp Premium, Telio CAD, Ceramill Temp, Shofu Block HC, and conventional polymer PalaXpress. Specimens were aged in distilled water for 60 days at 37 °C and the evaluation of the residual monomer elution was made through UV spectrophotometry. Statistical analysis was carried out in the SPSS software. One-way ANOVA and Scheffé post hoc test were applied (

Analyze and quantify the residual monomer elution of nine conventional and CAD/CAM (computer-aided design/computer-aided manufacturing) dental polymers during artificial aging.
Materials and methods
A total of 360 square–shaped specimens (14 × 12 × 2 ± 0.05 mm) were fabricated from eight CAD/CAM polymer blanks (
n
= 40): Avadent Base material, Avadent Teeth material, PMMA Multi blank, PMMA Mono blank, Temp Premium, Telio CAD, Ceramill Temp, Shofu Block HC, and conventional polymer PalaXpress. Specimens were aged in distilled water for 60 days at 37 °C and the evaluation of the residual monomer elution was made through UV spectrophotometry. Statistical analysis was carried out in the SPSS software. One-way ANOVA and Scheffé post hoc test were applied (
α
< 0.05).
Results
Aging time significantly changed the elution in all groups, except for PalaXpress. Statistically significant differences of elution were found between the materials. Shofu Block HC presented the highest, whereas PMMA Multi blank A3 and Mono blank A1 presented the lowest elution after the 60th day of aging.
Conclusions
CAD/CAM dental polymers as well as the conventional polymer PalaXpress eluted residual monomer within aging time. The differences in elution were material-dependent; still, the maximum elution found is below the specified threshold of ISO standard 20795-1.
Clinical relevance
With the evolution of CAD/CAM technology, material’s manufacturers have invested in the development of polymeric materials with higher resistance and stability to produce indirect restorations using CAD/CAM. It is expected that these materials present lower elution of residual monomer than conventional polymers.</description><identifier>ISSN: 1432-6981</identifier><identifier>EISSN: 1436-3771</identifier><identifier>DOI: 10.1007/s00784-019-02947-4</identifier><identifier>PMID: 31098712</identifier><language>eng</language><publisher>Berlin/Heidelberg: Springer Berlin Heidelberg</publisher><subject>Aging ; Computer-Aided Design ; Dental Materials ; Dentistry ; Materials Testing ; Medicine ; Original Article ; Polymers ; Polymethyl Methacrylate ; Polymethylmethacrylate ; Spectrophotometry ; Statistical analysis ; Surface Properties ; Teeth</subject><ispartof>Clinical oral investigations, 2020-01, Vol.24 (1), p.277-284</ispartof><rights>Springer-Verlag GmbH Germany, part of Springer Nature 2019</rights><rights>Clinical Oral Investigations is a copyright of Springer, (2019).
