“…For example, specific drawbacks have been described in the literature for articulating papers: they range from poor association between mark size and occlusal load (Qadeer et al , 2012), to low-reproducibility of contacts or operator-variability (Kerstein, 2008). The moisture (saliva) of intraoral environment, or some smooth materials adopted for tooth restorations (i.e: gold, metal alloys or ceramics), along with a repeated use of the indicator, are also able to affect the ink-release from articulating paper and thus impair reproducibility of markings (Saracoglu and Ozpinar, 2002). Moreover, despite a wide range of materials is available, no clear guidelines or standards have been described for proper use or for specific clinical scenarios (Millstein, 2008); we may speculate that there is still room for improvement (i.e:…”

“…Carossa et al, 29 using an articulator-mounted cast and recording strips, concluded that the assessment of OCs was significantly influenced by paper thickness, operator experience, bite force, and time. Saracoglu et al 30 used acrylic resin casts mounted in an articulator and a universal testing machine to compare occlusal indicator reliability with an in vivo measurement. They recommended that the recording materials be used carefully in the mouth and that teeth be dry during occlusal analysis.…”

“…Articulating paper under extraoral conditions was also used to evaluated OCs. [29][30][31] Articulating paper is preferred primarily for detecting OCs because of low cost and ease of application. 29 However, it should only be used for qualitative analysis to establish the location and number of contacts.…”

Objective: To test the hypothesis that long-term use of an oral appliance (OA) does not cause changes in the occlusal contact area (OCA). Materials and Methods: Baseline and follow-up treatment study models were obtained for 45 patients with obstructive sleep apnea who had been using an OA for 4 or more days/week for more than 5 years. Study models in centric occlusion, with an inserted pressure-sensitive sheet, were loaded in compression. An image scanner was used to evaluate OCA. Results: A significant change in total OCA was identified in 39 patients (86.7%): a decrease in 26 (66.7%) and an increase in 13 (33.3%) patients. Regional changes Ͼ5% were observed in Ͼ90% of patients in each of the three regions. In the molar and premolar regions, 24 (53.3%) and 27 (60.0%) of the patients showed an OCA decrease, while only 16 (35.6%) and 15 (33.3%) showed an increase. Conversely, for the anterior region, more increases (24 patients-53.3%) than decreases were identified. Conclusion: The hypothesis is rejected. Long-term OA therapy resulted in dramatic changes of occlusion, suggesting that monitoring of occlusal changes is required.

“…Variations in articulating paper marking may also arise from differences in paper thickness, the extent to which it is impregnated with saliva, and the force of the patient's bite. Because of these types of variation, many researchers have been able to demonstrate that contact profiles determined using articulating paper are not reproducible, even when made under apparently identical conditions 9,20,31,38,39 .…”

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.
