Computerized Digital Accuracy versus Articulation Paper
Dr. Fallah uses state-of-the-art, accurate diagnostic and measurement devices such as the T-Scan II. The T-Scan is a device that virtually eliminates the old "trial and error" approach necessary when articulation paper is utilized in analysis of jaw and tooth pressure and alignment during occlusal measurements.
Dr. Fallah uses this advanced technology to ensure unsurpassed accuracy of occlusal and bite data for his patients -- for the most complex -- and even simplest of dental treatment.
The assessment procedure is extremely efficient. No clumsy or messy articulation paper to deal with. The digital data provides a permanent record and guesswork is eliminated.
The T-Scan's 3-D representations are easy to comprehend and provide easy to interpret data for patients. These concise data and occlusal information can be critical in complex dentistry including measurements required for correct placement of dental implants.
The T-Scan allows corrections to bite issues that have the potential to be associated with loose, shifting teeth or teeth that are overly-impacting each other. Excessive pressures on supporting gum and bone structure can be avoided with biting and chewing loads evenly distributed. This balance helps prevent or overcome issues such as TMJ.
A study was performed in 2007 with results that showed the ineffectiveness and inaccuracies of articulating paper:
Determining a Relationship Between Applied Occlusal Load and Articulating Paper Mark Area - Jason P. Carey*,a,Mark Craigb, Robert B. Kersteinc and John Radked
"Articulating paper mark size has been widely accepted in the dental community to be descriptive of occlusal load. The objective of this study is to determine if any direct relationship exists between articulating paper mark area and applied occlusal load. A uniaxial testing machine repeatedly applied a compressive load, beginning at 25N and incrementally continuing up to 450N, to a pair of epoxy dental casts with articulating paper interposed. The resultant paper markings (n = 600) were photographed, and analyzed the mark area using a photographic image analysis and sketching program.
A two-tailed Student's t-test for unequal variances compared the measured size of the mark area between twelve different teeth (p < 0.05). Graphical interpretation of the data indicated that the mark area increased non-linearly with increasing load. When the data was grouped to compare consistency of the mark area between teeth, a high variability of mark area was observed between different teeth at the same applied load. The Student's t-test found significant differences in the size of the mark area approximately 80% of the time. No direct relationship between paper mark area and applied load could be found, although the trend showed increasing mark area with elevating load. When selecting teeth to adjust, an operator should not assume the size of paper markings, accurately describing the markings' occlusal contact force content."
