“…The lowest setting shrinkage strain showed O-Bite (polyvinylsiloxane-based material): 0.18 ± 0.03–0.16 ± 0.03% at 5, 7, and 10 min, followed by polyether-based material, whereas dimethacrylate-based material had the highest degree of shrinkage. In the study of Anup et al, dimensional change and accuracy of polyvinyl siloxane bite registration material were also statistically significant but clinically insignificant [ 6 ]. Campos and Nathanson [ 5 ] examined the compressibility of two addition silicones interocclusal record materials, analyzing the changes of maxillomandibular relations at the condyle region.…”

“…Currently, polyether and polyvinyl siloxane bite recording materials are increasing in popularity due to their handling characteristics, accuracy, and dimensional stability [ 2 , 6 , 12 , 13 ]. These materials are very similar to dental impression materials, but their properties following modifications via the addition of plasticizers and catalysts are unknown [ 2 , 6 , 7 ]. They do not require a carrier and are cost effective.…”

Background. Addition silicones are popular as dental impression materials and are used in bite registration procedures. Objective. This study aimed to compare the postsetting elasticities and other mechanical properties of thirteen addition silicone interocclusal recording materials. Materials and Methods. The following materials were investigated: Colorbite D, Futar D, Genie Bite, Jet Blue Bite fast, Memoreg 2, O-Bite, Occlufast Rock, Omni-Bite Plus, Regidur i, Registrado X-tra, Regofix transparent, StoneBite, and Variotime Bite. Thirty specimens of each material were tested. The elasticities and strengths of the materials were measured with a universal testing machine, and computer software was used to determine the E-moduli, ultimate tensile strengths, and ultimate elongations of the specimens. Results. The results were subjected to statistical analysis using the Kruskal-Wallis test (p ≤ 0.05). The statistics revealed that the mean E-modulus values varied significantly across the materials (p = 0.000) and were highest for the StoneBite and Registrado X-tra and lowest for the Regofix transparent. The ultimate tensile strengths were highest for the Regofix transparent and Registrado X-tra (p = 0.000) and lowest for the Jet Blue Bite fast and Memoreg 2 (p = 0.000). The elongation percentages at the point of breaking varied significantly across the materials (p = 0.000); the lowest value was observed for the StoneBite, whereas the Regofix transparent nearly doubled original length. Conclusions. The authors concluded that materials with the high E-moduli and great ultimate tensile strengths may be most useful clinically. Registrado X-tra and StoneBite best met these criteria.

To achieve a successful prosthesis, it is important to achieve harmony between the maxillomandibular relationships. This does not pertain only to the opening or closing but is a complex relationship which exists in three dimensions. Hence, it is very important to record this relationship with the least possible error to obtain a successful prosthesis. To record this maxillomandibular relationship, numerous materials are in use and what matters are the precision of the recording materials and their stability. This article seeks to present a review of major bite registration materials and their modification as well as their advantages and disadvantages.

“…Although numerous studies have been made on the accuracy and stability of impression,[ 5 6 ] few studies on the dimensional stability of different interocclusal recording materials have been investigated[ 7 8 9 10 ] but the effect of disinfection and its method on the dimensional accuracy of interocclusal recording materials have not been reported previously.…”

Objective:To evaluate and compare the effect of 0.5% chlorhexidine gluconate, 1% sodium hypochlorite, and 2% glutaraldehyde by immersion and spray atomization technique on the linear dimensional stability of Jet bite, Aluwax and Ramitec interocclusal recording materials.Materials and Methods:Three representative materials: Jet bite (addition silicone), Aluwax and Ramitec (polyether) were mixed according to manufacturer's instructions and then specimens were prepared according to the specifications of ISO 4823. All the specimens except the control (distilled water) were treated with disinfectant solutions (0.5% chlorhexidine gluconate, 1% sodium hypochlorite, and 2% glutaraldehyde) for 30 and 60 min (n = 10) by spray and immersion technique. Once removed from the solutions, the test samples were washed in water for 15 s, dried and measured after 24 h 3 times using a measuring microscope with an accuracy of 0.0001 mm. Two-way ANOVA and Tukey's test with significance level of 5% were used to assess the statistical data (α = 0.05).Result:All groups showed no significant difference statistically, in linear dimension when disinfected for 30 min by spray or immersion technique. Polyether had significantly higher dimensional variation when immersed in sodium hypochlorite for 60 min. Addition silicone showed the least dimensional change which ranged from 0.024% to 0.05%, followed by polyether from 0.004% to 0.171% and Aluwax from 0.146% to 0.228%.Conclusion:To preserve the dimensions and surface of the recording materials and effective microbial elimination, restrictions should be applied in the method of disinfection and time duration. However, using the disinfectants either by spray or immersion technique, the dimensional change was <0.5% which was not clinically significant according to the American Dental Association specification no. 19 criteria within the first 24 h.
