An In Vitro Study of Condylar Displacement Caused by Interocclusal Records: Influence of Recording Material, Storage Time, and Recording Technique

摘要: Purpose To evaluate the condylar displacement after mounting working casts using different interocclusal recording materials and to analyze influence of storage time technique on caused by record. Materials Methods Eight records were made in each following groups: G1: Aluwax (aluminum wax), G2: Beauty Pink wax (hydrocarbon compound), G3: Futar D Fast, G4: Scan (G3, vinylpolysiloxane), G5: Ramitec (polyether), G6: LuxaBite (composite resin based bis-acryl), G7: corrected with Aluwax. A condylar-positioning indicator measured three planes for two periods 1 48 hours. Two-way ANOVA was used determine influences factors: (1) region (record non-record side), (2) time, (3) technique. The statistical significance level set at p < 0.05. Results The vertical record side hour ranged between 0.29 mm (Aluwax) 0.14 (Futar Scan). lateral 0.13 0.02 (Ramitec) while anteroposterior 0.15 0.04 showed generally lower values than other tested (0.03, 0.02, 0.07, respectively). On side, that side. increased a hours all materials. Both factors, technique, had statistically significant displacement. Conclusions Based results, condyle higher or displacement. Elastomers significantly less waxes uncorrected composite resin. Corrected
