“…However, spring action found in these materials may cause inaccuracies during mounting of the casts. 18 Karthikeyan et al in 2004 19 compared the dimensional stability of three different interocclusal recording materials i.e. addition silicones, aluwax and zinc oxide eugenol at the time intervals of 1h, 24h, 48h and 72h.…”

Dimensional stability of commonly used interocclusal records is a significant factor for precise articulation of patient's diagnostic and working casts in the fabrication of well fitting prosthesis with satisfactory occlusion. The aim of this study was to measure the dimensional accuracy of modeli g wax, aluwax, addition silicone and modeling wax corrected with zinc oxide eugenol. Total of 80 samples were fabricated. The dimensional accuracy of these materials was tested in three planes i.e. anteroposteriorly, mediolaterally and vertically. The dimensional accuracy in horizontal plane was measured with travelling micro cope and in vertical plane with digital vernier caliper. The values obtained were stati tically analysed y A OVA and Tukey HSD-Honestly significa t difference. olyvi ylsiloxane was observed to be the most dimensionally accurate material and modeli g wax, the least accurate material of all the materials tested.

“…[ 17 19 ] Majority of them transfer the record to laboratory in 1–24 h (62.9%) and 37.1% transfer within 1 h. The ideal time required for the record to be articulated is polyether interocclusal records must be articulated within 48 h, Polyvinylsiloxane interocclusal records must be articulated within 24 h and wax, and zinc-oxide eugenol should be articulated within 1 h to get accurate registration. [ 20 ] If the wax is not articulated within 1 h, distortion may occur in it because of volatiles loss and stress release property. [ 21 22 23 ]…”

Background:Majority of general dental practitioners provide fixed dental prosthesis in India. The aim of this study was to gather information on selection, usage, and materials and methods employed in interocclusal records and their communication with the dental laboratory for restorative procedures practised by dentists in Indore district to evaluate and to improve the quality of current practice.Aim and Objectives:The purpose of this cross-sectional study was to understand and to evaluate dental practitioner's knowledge on interocclusal recording materials, its usage, their clinical implications, and their correlation with the laboratory in restorative procedures practiced by the dental practitioners in Indore district.Materials and Methods:A questionnaire comprising 11 questions were framed and circulated among general dental practitioners except prosthodontists, and the results were statistically analyzed.Results:Most of the practitioner's preferred wax (54.6%) as an interocclusal recording material over polyvinylsiloxane and polyether. Most of the dentists preferred full arch interocclusal record (27.8%). About 51.5% clinicians trimmed the interocclusal record before sending to the laboratory.Conclusion:From this survey, it has been concluded that the practitioner's attitude toward the use of interocclusal record materials is found to be deviated from well-acknowledged prosthodontic quality guidelines.

“…The above mentioned time intervals were based on the time required to carry the interocclusal record material to distant laboratory or the delay in the articulation of the cast in the laboratory [10]. Several factors contribute to the dimensional changes of the material used for interocclusal recording.…”

To evaluate and compare the dimensional stability, accuracy and surface hardness of three interocclusal recording materials at various time intervals. Polyvinylsiloxane, Zinc oxide eugenol, Aluwax were taken for this study. A stainless steel die of ADA specification no 19. was prepared. A total of ten samples were made with each group. The samples were measured using a travelling microscope of 10× magnification at 1, 24, 48 and 72 h time intervals. Five readings were taken for each sample, the mean was considered to measure the dimensional change, accuracy and surface hardness. The values obtained were statistically analysed by ANOVA and Tukey HSD-Honestly significant difference. Polyvinylsiloxane was the most dimensionally stable, accurate and had the highest surface hardness among the three inter-occlusal materials.
