“…Note, the lateral shift and increase in peak pressure with increasing lateral shifting of the patella. In this case, peak pressure from the normal reference to the 1.0 mm displaced position increased by a factor of 2. change in contact mechanics because of insertion of the Fuji film , possible crinkle artifacts (Liggins, 1997), and inaccuracies with Fuji film calibration (Liggins et al, 1995).…”

“…Due to its ease of application, the pressure-sensitive film technique has been widely used to study contact area and pressure in a wide range of fields (Liggins et al, 1995;Harris et al, 1999;Zdero et al, 2001;Hoffmann and Decker, 2005;Bachus et al, 2006). Pressure-sensitive film can be applied directly onto the impact object to assess the interface force, pressure distribution, and contact area.…”

a b s t r a c tImpact pressure and bruising of apple fruit were measured by means of a pressure-sensitive film technique, in order to develop methods for assessing and predicting bruising of apples resulting from impact loads during the course of transport and handling. Results of impact tests with apples indicate that when the fruits are dropped from different heights onto different impacting surfaces, the bruise area and volume could be assessed and predicted by regression models based on the impact force obtained from the pressure-sensitive film (F PSF ). The coefficients of determination (R 2 ) for bruise area and bruise volume were found to be 0.91 and 0.95, respectively. Crown

“…18 The pressure transducers, which are applied between two surfaces, are another popular alternative method of pressure measurement. 11,20 However, the introduction of this additional transducer layer between the two areas of contact will result in a greater pressure reading than the actual situation, unless one of the surfaces is implanted with the transducer. The process of implantation disrupts the properties of one of the contact surfaces.…”

“…6,11 To avoid interfering with the strain that is being measured, technologies such as pressure sensitive films are being developed that endeavor to reduce the thickness of the pressure sensor in order to minimize the interface contact. Pressurex Ò (Fuji Photo Film Co., Ltd Tokyo, Japan), a pressure sensitive polyester film, provides direct pressure distribution and quantification means.…”

Abstract-The force imparted by removable thermoplastic appliances (RTA) onto teeth has not been investigated in the past. This investigation was designed to explore a novel methodology to measure the magnitude and identify the pattern of this force. Eight patients with moderate malocclusion were selected. In each patient, the palatally mal-positioned upper first premolar was corrected by wearing a series of four ClearSmile Ò RTA over a duration of 8 weeks. When constructing RTA, the ClearSmile Ò Company was advised that the amount of movement to be programmed into each appliance was 0.5 mm. The Pressurex Ò film was used to measure the pressure generated by ClearSmile Ò RTA against the palatal surface of the upper first premolar for buccal tipping movement. Three measurements were conducted respectively upon the issue and retrieval of each appliance (after 2 weeks of wear), resulting in 24 pressure measurements for each patient. Digital imaging and spectrophotometry analysis were employed to quantify the stain intensity mounted by the pressure on the films. The irrelevant forces were subtracted out to allow an assessment of the force purely acting to buccally repositioning the tooth. The results revealed that (1) the mean force magnitude over 2 weeks of RTA wear was 1.12 N (SE = 0.72 N); (2) the higher force magnitude of 5.12 N (SE = 0.80 N) seen at the issue of the appliance declined drastically to -2.67 N at the time of retrieval. These findings suggest that ClearSmile Ò RTA exerts a high level of force against the tooth to be moved at the initial stage followed by a rapid force diminish.
