Evaluation of the Elastic Properties of Thirteen Silicone Interocclusal Recording Materials

Abstract

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.

فعالية حقن نقاط التوتر بالصفائح الغنية بالبلازما كطريقة لمعالجة الآلام المزمنة في الصداع التوتري المزمن

“…This study shows that 71 patients (57 females and 14 males) with a female: male ratio of 4:1 which means CTTH were more common in females than male, while in study done in 2017 shows that CTTH occur twice as frequently in women as in men [6].…”

“…It can appear as mild, moderate or intense pain in the head, neck and/or behind the eyes. TTH is often defined by patients as a feeling of having a tight band around their forehead [6].…”

Estimation of the elastic modulus and the work of adhesion of soft materials using the extended Borodich–Galanov (BG) method and depth sensing indentation

“…Thus, the accuracy of the BG method has been directly validated in this work. The obtained results also provide more experimental data on PVS properties, since this matter is not widely represented in literature (see e.g., Chai et al (1998); Wieckiewicz et al (2016))…”

A comparative evaluation of three dimensional accuracy of different types of interocclusal recording materials - an in vitro study

“…Walls [23] demonstrated the problems of inaccuracy in the transfer of maxillo-mandibular relations from the mouth to a semi-adjustable articulator. Even if the registration of the material is accurate but due to their inherent properties, the casts may not orient to the same settled position [24,25]. The final evaluation of any prosthesis depends upon an accurate duplication of the jaw relations in the laboratory.…”
