computerized occlusal analysis technology and cerec case finishing
International journal of computerized dentistry, 2008Co-Authors: R KersteiAbstract:Computerized occlusal analysis is becoming the principal tool available to clinicians with which to understand functional and parafunctional forces of occlusal contact, contact timing sequences, and occlusal surface interface pressures, which arise as teeth mill against each other during mandibular movements. Because recent research on Articulating Paper has revealed that Articulating Paper mark size does not measure occlusal forces predictably, the modern clinician needs to employ an occlusal contact measuring device that can reliably determine aberrant occlusal force concentrations and time prematurities. Computerized occlusal analyses can be used to guide the operator as to which tooth contact locations require appropriate occlusal adjustments. When inserting Cerec restorations, computerized occlusal analysis can be employed to target excessive force concentrations and time premature contacts to better preserve the Cerec materials, than can be accomplished with "Articulating Paper-only" occlusal adjusting. This Paper describes the evolution of computerized occlusal analysis, the system attributes, and illustrates its use in case-finishing Cerec bonded lingual guidance veneers.

tooth contacts at the mandibular retruded position influence of operator s skill on bite registration
Journal of Oral Rehabilitation, 2003Co-Authors: Shuichiro Yamashita, Y IgarashiAbstract:Occlusal conditions at the retruded contact position (RCP) have been thought to be among the aetiological factors for temporomandibular disorders. However, the role of these occlusal factors still remain unclear. The purpose of a series of studies was to investigate the locations of RCP contacts and to discuss their implication by the authors. In the study reported here, the influence of the operator's skill on bite registration was surveyed. Eighty-six dental students were selected as subjects. One specialist in prosthetic dentistry moved the subject's mandible up and down while guiding it gently backward until it rotated on its retruded axis. Once the initial tooth contacts were established, the operator checked them by using a thin Articulating Paper (direct method). On the other hand, six younger operators following precise instruction from the specialist about the technique of jaw guidance examined each of the subjects for location of RCP contacts using the indirect method. Silicone-based impression material was used for bite registration while the subject kept the jaw at this contact position (indirect method). Wilcoxon signed rank test was applied to evaluate differences between the expert operator and six younger operators regarding locations of RCP contacts. Results from the expert operator (direct method) showed that tooth contact at the first premolar was most frequently observed and the number of subjects who possessed unilateral tooth contacts was more than that with bilateral tooth contacts. On the other hand, in the case of the indirect method performed by younger operators, tooth contact patterns significantly differed from those of the direct method.

tooth contacts at the mandibular retruded position comparison of two different methods for bite registration
Journal of Oral Rehabilitation, 2002Co-Authors: Shuichiro Yamashita, Y IgarashiAbstract:Occlusal conditions at the retruded contact position (RCP) have been thought to be among the aetiological factors for temporomandibular disorders. However, the role of these occlusal factors remains still unclear. The purpose of this series of studies was to investigate the locations of RCP contacts and to discuss their meaning. In this part of the study, two different methods for bite registration at the RCP have been compared. Twenty dentists were selected as subjects for this study. One expert operator moved the subject's mandible up and down while guiding it gently backward until rotating on its retruded axis. Once the initial tooth contacts were established, the operator checked them using a thin Articulating Paper (direct method). Silicone-based impression material was used for bite registration while the subject kept the jaw at this contact position (indirect method). Differences between the two registration methods regarding locations of tooth contacts were evaluated. Results from the direct method showed that tooth contact at the first premolar was most frequently observed. Statistical difference was not shown between the two registration methods regarding locations of RCP contacts.

ability to correctly select high force occlusal contacts from Articulating Paper markings
Advanced Dental Technologies & Techniques, 2020Co-Authors: Eddie Basson, Robert B Kerstein, John RadkeAbstract:Subjective Interpretation of Articulating Paper markings is still being taught as being safe for patients, despite that studies show dentists choose incorrect forceful and non-forceful contacts when using its principles. The Specific Aims of this study were to replicate or contradict prior Subjective Interpretation study findings, by using T-Scan contact force levels in a single Articulating Paper-marked quadrant photograph, to see if dentist-participants could visually select the 2 highest force occlusal contacts.

clinician accuracy when subjectively interpreting Articulating Paper markings
Cranio-the Journal of Craniomandibular Practice, 2014Co-Authors: Robert B Kerstein, John RadkeAbstract:AbstractAims:The aim of this study was to determine whether Subjective Interpretation of Paper markings is a reliable method for identifying the relative occlusal force content of tooth contacts.Methodology:295 clinicians selected the “Most Forceful” and “Least Forceful” occlusal contacts in six occlusal-view photographs of Articulating Paper marks that were later compared against computerized occlusal analysis relative occlusal force measurements of the same tooth contacts. Means and standard deviations were calculated by years in clinical practice and by number of occlusion courses taken. A Chi-square analysis was also performed.Results:The mean correct for 295 participant dentists was 1·53 (±1·234). There were no significant differences found for years in practice (P>0·16) or number of occlusion courses taken (P>0·75). The Chi-square analysis showed a sensitivity of 12·6%, a specificity of 12·4%, a positive predictive value of 12·58%, and a negative predictive value of 12·42%. Chance was calculated at ...

Articulating Paper mark misconceptions and computerized occlusal analysis technology
Dental implantology update, 2008Co-Authors: Robert B KersteinAbstract:Articulating Paper mark size is now understood to be non-descriptive of occlusal loads; in fact, many different sized marks can represent the same load, and equal sized marks do not represent similar loads. With a reported reliability between mark size and applied occlusal load of only 21%, choosing the Paper marks to occlusally adjust, based upon their relative size and operator-subjective assessment of those various sizes, is tantamount to clinical guessing. Computerized occlusal analysis completely removes the operator subjectivity from the clinical decision-making process when attempting to isolate problem occlusal contacts. When an operator properly uses this technology, mark size, mark color-depth, donut-shaped halo contacts, as well as other color and mark appearance characteristics, are ignored as force indicators and used only as contact locators. Operator-subjective Paper mark misperceptions are replaced with accurate knowledge of the true and measured contact order, contact applied load, contact quality, and proper contact isolation where problematic. This results in better overall force application to any installed implant prostheses during occlusal function, thereby enhancing its chance for an undamaged clinical service lifespan.

determining a relationship between applied occlusal load and Articulating Paper mark area
The Open Dentistry Journal, 2007Co-Authors: Jason P Carey, Robert B Kerstein, Mark Craig, John RadkeAbstract: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.
