Özet
<p>Objective: To evaluate the surface detail reproduction of four types of impression materials compatible for the socket impression in the fabrication of ocular prosthesis.</p><p>Material and Method: Three alginate impression materials (orthoprint(OP), Ca37(C), Ophthalmic Alginate (OA) and a polyvinyl siloxane material (Affinis (P)) have been tested. A total of 40 impressions were made of stainless steel metal dies (ADA specification 19). The dies had 2 vertical and 3 horizontal lines inscribed on their superior surfaces. The measurements have been conducted on the 20-50-75 µm horizontal lines on the surface of the impression. Surface detail reproduction was evaluated using a microscope at 80X magnification. Statistical analysis was performed (one-way ANOVA and Bonferroni, alpha=0.05). </p><p>Results: Polyvinyl siloxane material resulted in the highest values and showed the most accurate surface at all of the 20-50-75 µm lines; whereas, lowest values were observed with Orthoprint.</p><p>Conclusion: Polyvinyl siloxane impression material showed the highest surface detail necessary for the construction of an ocular prosthesis among other impression materials tested</p>
