| dc.description.abstract | ABSTRAK Stabilitas dimensi cetakan alginat sangat penting untuk mendapatkan model yang akurat. Penelitian ini dilakukan untuk mengetahui ada atau tidaknya perubahan signifikan dimensi linear pada model gips yang dihasilkan dari cetakan alginat stabilitas tinggi yang mengalami penundaan pengecoran selama 5 hari. Penelitian dilakukan secara eksperimental laboratoris menggunakan 20 sampel terbagi dalam 4 kelompok. Kelompok I dan III merupakan model gips hasil pencetakan alginat stabilitas tinggi dan konvensional yang langsung dilakukan pengecoran. Kelompok II dan IV merupakan model gips hasil pencetakan alginat stabilitas tinggi dan konvensional yang ditunda selama 5 hari dalam wadah dengan kelembaban 100%. Perubahan dimensi diukur pada diameter bagian atas dalam arah bukal-lingual, distal-mesial, serta jarak antar gigi menggunakan jangka sorong digital merk Mitutoyo berskala 0,01 mm. Hasil rata-rata diameter mesial-distal (a) kelompok I, II, III sebagai kontrol, dan IV adalah 8,410 mm, 8,520 mm, 8,420 mm, dan 8,620 mm. Rata-rata diameter mesial-distal (b) adalah 8,314 mm, 8,416 mm, 8,315 mm, dan 8,513 mm. Rata-rata jarak antar gigi (c) adalah 13,312 mm, 13,240 mm, 13,316 mm, dan 13,191 mm. Rata-rata diameter bukal-lingual (d) adalah 8,411 mm, 8,530 mm, 8,410 mm, dan 8,608 mm. Rata-rata diameter bukal-lingual (e) adalah 8,350 mm, 8,441 mm, 8,340 mm, dan 8,524 mm. Data diuji secara statistik dengan metode ANOVA (α = 0,05). Simpulan penelitian ini menunjukan model gips hasil pencetakan alginat stabilitas tinggi yang mengalami penundaan pengecoran selama 5 hari mengalami perubahan secara signifikan.

This study was to find the linear dimensional changes of the cast made from delayed pour high stability alginate impression after 5 days. This experimental laboratory study used 20 samples, divided into 4 groups. First and third group were the generated cast produced by immediately pour into high stability and conventional alginate impressions. Second and fourth group were the generated cast produced by delayed pour into alginate impression for 5 days in storage with 100% humidity. Dimensional changes were measured in the upper part of the cast from buccal-lingual and mesial-distal direction and also measured in the outer distance between the upper cast used Mitutoyo digital caliper scaled 0.01 mm. The result of mesial-distal (a) diameter average of group I, II, III as control, and IV were 8,410 mm, 8,520 mm, 8,420 mm, and 8,620 mm. Meanwhile, diameter averages of mesial-distal (b) were 8,314 mm, 8,416 mm, 8,315 mm, and 8,513 mm. The averages of distance between each teeth (c) were 13,312 mm, 13,240 mm, 13,316 mm, and 13,191 mm. The diameter averages of buccal-lingual (d) were 8,411 mm, 8,530 mm, 8,410 mm, and 8,608 mm. The diameter averages of buccal-lingual (e) were 8,350 mm, 8,441 mm, 8,340 mm, and 8,524 mm. The data were analyzed using ANOVA (α = 0.05). The result show there were significant linear dimensional changes on gypsum cast made from high stability alginate impression and then poured after 5 days.
