The traditional occlusal indicators used in dental practice are articulation papers, Shim-stock foils, elastomeric impression materials, and occlusal wax strips. These static dental materials have been widely believed to have occlusal force descriptive capability. However, modern material studies are challenging the widespread belief that occlusal indicator materials can measure differing occlusal force levels. This chapter evaluates the force reporting limitations of these static occlusal indicators, and discusses how clinicians subjectively interpret their appearance characteristics to determine differing occlusal force levels. This chapter then compares these non-digital occlusal indicators to the T-Scan computerized occlusal analysis technology, that records and displays precise, quantifiable, relative occlusal force variances, and occlusal contact timing sequences. This digital data aids the clinician in making a more accurate occlusal analysis, and can guide the clinician in t...
T- Scan a digital pathway to occlusal perfection: a review
2016
For years, dental occlusion had been largely a matter of guess work for dentists. Articulation paper marks, waxes, pressure indicator paste, etc. were the only tools available to access and balance the bite force. These methods do not detect simultaneous contact, nor do they quantify time and force. With the advent of T-SCAN the scenario has changed. The evolution of T SCAN from 1st generation to 8th generation (1847-2015) has revolutionized the concept of occlusal analysis. The modern version of T SCAN system released in 2012 i.e. T SCAN 8 was purposefully designed to minimize the T SCAN 3 user interface complexity. T SCAN 8 has reversed desktop graphics for simpler data display with less software, toolbar buttons and icons. The system comprises of Microsoft windows based software, associated hardware and patented thin disposable sensor. Patient is asked to bite on ultra-thin senor. The occlusal contact is transferred to the computer and presented in a dynamic movie format. It ther...
Comparative occlusal study analog and digital – a pilot study
Romanian Journal of Stomatology, 2021
The aim of this study was to determine whether or not the analysis of maximal intercuspation, protrusive and laterotrusive movements requires an additional digital method of occlusal diagnosis using the T-Scan™ Novus™ device (TekScan). In this observational study, we retrospectively examined a number of 10 subjects which were divided into 2 groups: the 1st group involved patients with intact dental arches and the 2nd group with patients that had received implant-supported restorations. The methods of analysis involved the calibrated articulating paper of 200 and 40 micrometers, and also the T-Scan™ Novus™ device (TekScan). The following data were collected: contact points in maximum intercuspation (functional and premature contacts), the pairs of teeth performing protrusion and right/left laterotrusion, active/passive interferences and premature contacts during protrusion and right/left laterotrusion. Descriptive statistics were obtained using the MedCalc Statistical Software versio...

BACKGROUND: Occlusion is one of the most important aspects of dentistry. Dental occlusion differs among individuals. Subsequently, realizing the correct physiological occlusion is essential for the complex functioning of the stomatognathic system during the mouth prosthodontics rehabilitation. AIM: The purpose of this review paper is to provide an overview of the T-Scan system over its utility in fixed restorations occlusal analysis. MATERIALS AND METHODS: An electronic search was performed through PubMed, MEDLINE, Web of Science, and Google Scholar. The inclusion criteria for selection were articles reporting the occlusion analysis using articulating paper as a conventional method, and occlusion analysis using T-Scan III digital electronic system to detect contact points between the mandibular and maxillary teeth. RESULTS: The electronic search identified 70 titles. Authors ended up with eight studies which have been divided into two tables. The first table is described four studies which present a comparison between the T-Scan III electronic system and articulating paper. The second table is described 4 studies which present occlusal analysis using the T-Scan III electronic system. CONCLUSION: Based on the published literature, this review has highlighted some advantages of the T-Scan electronic system compared to articulating paper. The studies showed that the T-Scan computerized occlusal analysis which can provide quantifiable occlusal force and timing data that will make it possible to better protect brittle dental ceramic, and most importantly, to improve the quality of patient's lives with improved bite comfort and chewing function.
Objective: This literature review summarizes the properties, advantages, limitations, and clinical implications of employing static occlusal indicators compared to quantifi-able digital occlusal indicators during occlusal adjustments. Method: An electronic database search of dental literature was carried out in PubMed/MEDLINE using the key words Occlusal Indicators, Occlusal Assessment, Static, Reliability, Dynamic, Repeata-bility, Validity and Clinical Accuracy. A total of 231 papers were isolated, with 129 papers considered for review. Results: The included papers were grouped by Static and Dynamic Occlusal indicators. The numbers of papers in the Static Group was extremely low (only 20 papers) compared to The Dynamic group (T-Scan: 89; Dental Prescale: 28; Intraoral Scanners:17). Conclusion: Little evidence supports the use of static occlusal indicators due to their high degree of subjectivity required during implementation. However, much scientific evidence supports the use of T-Scan, as it measures relative occlusal forces and timing objectively, accurately, and repeatedly. For the improvement of Occlusal Practice, Subjective Interpretation using Static occlusal indicators should be replaced with digital ones for objective measurements. Clinical Relevance: The computerized occlusal analysis system is well studied and has the capacity to provide precise time and force sequencing information to objectively evaluate occlusal contacts for improved treatment outcome.
Computerised Occlusal Analysis Utilising T Scan™ and it’s Implications in Periodontology
Modern Approaches in Dentistry and Oral Health Care, 2018
Introduction: The periodontium has its own adaptive capacity to the forces exerted on the teeth, this varies in different persons and in the same persons at different times. In current practise, the occlusal factors acting on the tooth are examined by articulation paper marks, waxes, pressure indicator paste, etc. However, the drawbacks of these methods are that they do not detect simultaneous contact nor do they quantify time and force. This study was conducted to determine and to analyse the distribution of occlusal loading forces, occlusal contact variability and its correction in the management of periodontitis using T-Scan III™. Methods: A total of ten chronic periodontitis patients were selected for the study. Scaling and root planing procedure and occlusal analysis using T-Scan III™ were performed on them. The amount of occlusal forces was found to be highly concentrated either on the right or the left side of the dental arches. Thus, the occlusal adjustments were carried out to minimize and dissipate the abnormal occlusal forces. Result: T-Scan analysis was repeated to analyse for the distribution of occlusal forces which depicted a reduction in the amount of occlusal forces and these forces were distributed nearly equally on the dental arch. Conclusion: Comparing and analysing the occlusal distribution of forces prior to and after the occlusal adjustments using T-Scan III™ system showed equilibrium in occlusal force distribution.
A handheld and convenient occlusal scanner
International Journal of Advance Research, Ideas and Innovations in Technology, 2020
The idea to determine the alignment of the teeth and jaw placement. This entirely covers the examination of human teeth between the age of neonatal to adolescence where the majority of the teeth issues and problems occur. We know for a fact that humans up to the age of 8 have milk teeth that constantly get replaced so these issues can be diagnosed early and treated accordingly. So this device uses a piezoelectric sensor or pressure gauge to measure the pressure applied while biting. These parameters are analyzed and then fed to a microcontroller where appropriate techniques are adapted to give a detailed analysis and determine the intensity of the issue. This system uses an amalgam of electronics and the medical sector. This is a portable structure that can be implemented in a dentist’s workplace.

Virtual occlusal record: a literature review about the digital method
Research, Society and Development
To produce prostheses through the digital flow, it is essential to transfer the correct patient’s interocclusal relationship to the digital software program, enabling the articulation of virtual models. Therefore, the aim of this study was to carry out a narrative literature review to describe and discuss aspects related to the virtual occlusal record realization, as well as its precision and accuracy in different clinical situations. Searches for scientific publications were performed in different databases and only articles in English related to the topic were selected. Different methods for the alignment of virtual models are described in the literature, the main one being the scanning of the patient in occlusion, usually in a position of maximum intercuspation. However, this technique may demonstrate disagreement with the patient's actual occlusal relationship due to several factors, and therefore studies were carried out to verify the precision and accuracy of these records...
Digital evaluation of occlusal forces: comparison between healthy subjects and TMD patients
Annali di stomatologia
provided the clinicians to access to a computerized device that can analyse the different characteristics of occlusal contacts. The purpose of this research was to use this device to study the occlusal forces comparing healthy subjects and TMD patients. Materials and methods. The study was conducted by following specific criteria to select participants; the sample was divided into two homogeneous groups: control group (CG) comprising healthy subjects, and dysfunctional group (DG) comprising TMD patients. The occlusal force analysis was performed using the computerized system T-Scan III V 5.20 T. The data were analysed with statistical methods. Results. The most significant differences emerged between the groups in the average occlusal load distribution and in the location of the centre of occlusal forces (COF). In particular, compared with the CG and the functional standard, reductions in the molar field forces on the second and first molars of 27% and 6.9%, respectively, were observed in the DG. The COF was located in the most forward position in TMD patients compared with healthy subjects. Conclusions. Although the differences in the distribution of the occlusal forces and the location of the occlusal centre of gravity were significant, the relationship between occlusal contacts and TMD remains to be fully clarified. Further research is needed to investigate whether studying occlusal force distributions in both healthy subjects and TMD patients.
