제안 방법
- SLM is a novel technique for fabrication of metal framework. In this technique, a high-power laser beam melts the layers of metal powders according to the scanned data and builds the restoration.
- Samples of both groups were first sandblasted with 250 µm aluminum oxide particles and ultrasonically cleaned for 10 minutes before the application of porcelain. To ensure a flat surface without any concavity or convexity, all samples were visually inspected before application of porcelain and the diameter of each sample was carefully measured.
대상 데이터
- Afterwards, acrylic models were sprued and were invested with a phosphate-bonded investment. Then, 910°C heat was provided and the alloy was melted at 1450°C. Centrifugal casting machine (model T.I.M500 Plus; Dentalfarm, Italy) was used to fabricate the samples.
- In the SLM group, Arcam system (Molndal, Sweden) was used to fabricate the samples. First, the fabricated acrylic mold was scanned.
- 5 × 3 × 25-mm rectangular strip, which served as the jig for fabrication of the rectangular acrylic model. Ten acrylic samples were made using Duralay acrylic resin (GC, America). Afterwards, acrylic models were sprued and were invested with a phosphate-bonded investment.
데이터처리
- Finally, the data were entered into SPSS software (version 20, IBM, San Francisco, CA, USA) and were statistically analyzed with Kolmogorov-Smirnov test and T-test.
이론/모형
- The load of the crosshead extension curves was documented for each sample. The fracture point or the point of crack-initiation in the specimens was measured in 3-point bend test.
