Interocclusal recording materials and techniques: A literature review

Abstract: Precise articulation of casts obtained from the patient is essential for proper diagnosis, treatment planning and successive prosthetic rehabilitation. In addition accurate transfer of maxillomandibular relation to the articulator eliminates the need for occlusal adjustments in final prosthesis, which require additional time and cost. Thus, it is essential to record this relationship with the least possible error to obtain a successful prosthesis. Knowledgeable application of the properties and the various sho… Show more

ObjectiveDigital technology in dentistry has advanced rapidly in recent years, and as a result, the identification of static virtual articulation as a crucial stage in the digital process has attracted increasing attention. The use of intraoral scanners (IOSs) has made the acquisition of occlusal records more efficient. The purpose of this article is to review information on evaluation methods and influencing factors on the accuracy of static virtual articulation obtained by intraoral scanners.OverviewAn electronic search of the published literature was performed up to November 2023 using five databases: PubMed, Cochrane, Embase, Web of Science, and Scopus. The inclusion criteria were defined as relevant clinical or in vitro English studies on the accuracy of the occlusal relationship obtained using intraoral scanners. Therefore, a total of 30 articles were selected, reviewed, and discussed. Based on the results of the literature review, three methods have been used to evaluate the accuracy of virtual interocclusal records, including distance measurement (10 studies), occlusal contact analysis (13 studies), and deviation analysis after superimposing casts (8 studies). However, direct comparisons between these studies are challenging due to the different methods employed. Factors that were found to potentially impact accuracies, such as the range of vestibular scans, the number and position of virtual interocclusal records (VIRs), the location and extension of edentulous areas, alignment methods, and evaluation software programs have been extensively studied, but the extent to which these factors affect accuracy remains uncertain and varies depending on the specific circumstances.ConclusionsA combination of multiple evaluation methods for a more rigid assessment of virtual interocclusal records may be a better approach. Attention should be given to the factors that may influence the accuracy of virtual interocclusal records. Future research should focus on optimizing these factors to improve the clinical applicability of virtual interocclusal records.Clinical SignificanceIn restorative dentistry, virtual interocclusal records obtained with intraoral scanners have been successfully used with acceptable accuracy, although they present some issues. Understanding the evaluation methods for virtual interocclusal records and the factors that may affect the accuracy of VIRs may lead to better use in clinical practice.

Background: The precise recording and transfer of maxillo-mandibular relationships are pivotal in prosthetic treatments. Aims and Objectives: To evaluate the efficacy of four bite registration materials: alu wax, hard wax, polyvinylsiloxane, and bis-acrylic resin, in accurately recording, maintaining, and reproducing the vertical interocclusal relationship on either side of the dentition. Materials and Methods: Thirty subjects within the age group of 20–45 years were selected. The difference in the reading of the vertical distance with the material and at maximum intercuspation is calculated individually for each record on the left and right sides. Results: On the right side, the lowest mean was observed in MIP and the highest in hard wax. On the left side, the lowest mean was observed in MIP, while the highest was in alu wax. Among the four bite registration materials evaluated, Luxabite and Jetbite exhibited the highest mean accuracy scores. Conclusions: Closure on interocclusal record material and bite release produce vertical discrepancies. Waxes showed the most, and bis-acrylic Luxabite and addition silicones showed the least dimensional distortion vertically.
