“…Moreover, eight Occlusion Times were recorded for each subject, and a mean value was calculated in order to approach a representative OT value per subject. The accuracy of the T-Scan system recording has been shown to be not altered by repeated measures, which was confirmed by other sensor and system recording accuracy studies (Koos et al, 2010;Hirano et al, 2002). The T-Scan system has been shown to repetitively record timed occlusal contacts quantitatively and dynamically, during a continuous mandibular movement (Kerstein et al, 1997;Wang and Yin, 2012).…”

“…In 1987 Maness et al (1987) reported the development of the first computerized system designed for occlusal analysis (T-Scan I, Tekscan, Inc. Boston, MA, USA). Notwithstanding its early problems (Harvey et al, 1992), its hardware and software evolution over the past 30 years, and improvements made to this technology which are included in the T-Scan III version (T-Scan III, Tekscan Inc. Boston, MA, USA with T-Scan HD sensor), ensured it is precise and reliable (Koos et al, 2010;Hirano et al, 2002).…”

a b s t r a c tIntroduction: Recently, some published studies show there is a multifactorial origin for Temporomandibular Disorders, but the dental occlusion's contribution to the development of Temporomandibular Disorders, and how it may influence the adaptive capacity of the Stomatognathic system, it's still unclear. The aim of this study is to evaluate the correlation between the Occlusion Time and Temporomandibular Disorders. Methods: A total of 54 patients were enrolled in the study (24 males and 30 females, mean age 27.94 ± 8.21 years). The TMD group (8 males and 10 females) consisted of subjects who presented with at least 1 of the following signs of Temporomandibular Disorders: Temporomandibular Joint sounds (clicking or crepitation), Temporomandibular Joint locking episodes, limited mandibular opening, painful limitation of mandibular movements, pain to palpation of the Temporomandibular Joint or of the masticatory muscles. The control group (16 males and 20 females) presented as free from Temporomandibular Disorders. The T-Scan III computerized occlusal analysis system was to record the subjects' Occlusion. Times during eight mandibular opening-closing movements. Results: The two-ways ANOVA test analyzed the variations for group and sex, showing that the TMD group mean Occlusion Time (0.64 ± 0.21 s) was statistically significantly longer than the control group mean Occlusion Time (0.45 ± 0.17 s) (p < 0.001). Significant differences were also found for gender where the mean OT of female subjects was longer than males one with statistical significance (p-value < 0.01). Conclusions: The computerized analysis of the Occlusion Time in patients affected by TMJ problems has to be carefully considered as adjunctive instrumental device.

“…One might conclude that current belief systems surrounding paper mark interpretation have been a contributing factor in the widespread disagreement on occlusion. Alternatively, the T-Scan® system (T-Scan I-9; Tekscan, Inc. S. Boston, MA, USA) has demonstrated 95% force distribution reproducibility per subject from intercuspation to intercuspation [7]. The T-Scan® has a near-perfect linear correlation of 0.9995 when measuring and reporting on occlusal contact timing [8].…”

“…A German research team validated the clinical use of the T-scan on 42 adult subjects 24 , estimating its error of measurement as 1%, its precision error as 2%, and its reliability error as 2.8%. They also asserted that changing the sensor or repeating the tests had no effect on the measurements obtained.…”

By definition, orthodontists take special care in achieving a high quality occlusion when finishing cases, believing good contacts are essential to maintain dental health, function, and insure stable long-term of results. The T-scan III system provides a real-time digitized analysis of occlusion, in both static and dynamic modes, and records the distribution of occlusal forces within the dental arches in different clinical situations. While the first T-Scan generations versions showed weaknesses, recent technical improvements have made T-scan a reliable and reproducible tool, whose findings are independent of the operator. It is now possible to calibrate the sensitivity of the sensor for individual patients, and to evaluate the quality of records so that comparisons can be made between various stages of a patient's treatment, as well as between patients. In addition to the accuracy of occlusal diagnosis, that often exceed clinical requirements, the T-scan III also can help understanding better each patient's functional pattern. This article describes the T-scan III occlusal analysis system, reviews current literature that evaluated its clinical use, and outlines its principal indications in dentofacial orthopedics. Four clinical cases treated with full bonded lingual appliance will illustrate how the Tscan III influences orthodontic case finishing : one case of ''occlusal discomfort'' after completion of surgical and orthodontic treatments, a case of cervical abfraction lesions, a case of anterior deep bite restored with an implant-supported prosthesis, and a case of severe facial hemiatrophy treated with a complex protocol.
