“…This is evident in various topics such as in processing errors that are possible during registration, during laboratory work or by the shrinking properties within the material itself. [1][2][3][4][5]12,13 Additionally, only few investigations about the reproducibility and characteristics of the habitual occlusion itself have been done and in these cases using mounted plaster models. [14][15][16] A study about static occlusion for instance examined the precision of the intercuspation in articulated models with an electronic evaluation by a condymeter.…”

OBJECTIVES: The aim of this in vivo study was to investigate how reproducible individuals find their habitual intercuspation. METHODS: A new type of highly accurate measuring procedure was involved using an intraoral optical scanning device (Cerec Bluecam). First, a pilot test investigated the accuracy of the procedure within a standardized setting. With regard to the in vivo study, fifteen participants with full dentition were selected. For each of these individuals, eight scans were taken both in the morning and in the afternoon. Furthermore, during each session, scans were taken both in horizontal and upright position. In order to compare this to ubiquitous used processes, plaster replicas of five individuals were investigated as well. The scans were analysed, and the differences in the position of the lower jaw were calculated by a specialized superimposition program (n=570 comparisons/OraCheck). RESULTS: The results showed that there was no significant difference between the time of day and the position of the patient. The overall mean±SD value for locating the habitual intercuspation was 42±34m, however ranging from 22±9m to 77±58m for single individuals. On the other hand, the differences in positioning plaster replicas reached a mean of 135±77m. CONCLUSIONS: The reproducibility of the habitual intercuspation can be obtained under in vivo conditions by a newly developed and highly accurate measuring procedure. Individuals with full dentition show values in average of 42m. CLINICAL SIGNIFICANCE: Determining the occlusal jaw relation is an important precondition in restorative dentistry and many methods are proposed for a proper occlusal registration. Although much is known about in vitro accuracy of these techniques, little is known how reproducible the habitual occlusal position itself is found between individuals.

“…used material in daily clinical practice because of its ease of handling, clinical versatility and low cost (3,18). In this study, the combination of acrylic resin and wax presented the lowest mean value of vertical separation between casts.…”

“…Despite its favorable properties, ZOE is a brittle material that strongly adheres to the dental surface due to contractions and, in the presence of excesses, it may suffer rupture and distortion and cause vertical displacement (9,17,18). In cases of edentulous areas, the ZOE paste in combination with the register base tends to dislocate the underlying mucosa, resulting in articulator mounting with a slight vertical opening (19).…”

Clinical evaluation of interocclusal recording materials in bilateral free end cases

Five combinations of materials commonly used for intermaxillary records in cases of bilateral free end saddle were evaluated: acrylic resin base + wax; acrylic resin base + wax + ZOE paste; acrylic resin base + wax + Duralay resin; condensation silicone; and acrylic resin plate + irreversible hydrocolloid. The materials were evaluated by measuring the vertical distance between pairs of reference points located on the bases of the upper and lower articulated casts. The measurements obtained by manual articulation of the casts were used as the standards to which the measurements obtained with the recording materials were compared. ANOVA revealed significant differences among the materials and the Tukey's test showed that condensation silicone differed significantly (p<0.05) from the acrylic resin + wax combination, while no significant differences (p>0.05) were observed among the remaining materials. The condensation silicone presented the greatest differences from the measurements obtained by manual articulation of the casts whereas the acrylic resin base + wax combination presented the least differences. Based on the findings of this study, the following scale of fidelity can be settled from best to worst: acrylic resin base + wax; acrylic resin plate + alginate; acrylic resin base + wax + ZOE; acrylic resin base + wax + Duralay; and condensation silicone.

Objectives To develop a simple way of recording occlusal contacts with proven inter-and intra-operator reliability. Setting Clinical skills laboratory in the University Dental Hospital of Manchester. Materials and methodsThe marked static occlusal contacts of 20 sets of models were recorded in a pseudo-clinical situation, by three dentists and in addition by one dentist on two occasions using a schematic representation of the dental arch -the 'occlusal sketch' . Results The median of Kappa agreement for inter-and intra-operator reliability was almost perfect. Conclusions The occlusal sketch is a simple, inexpensive and easy way of recording the results of an occlusal examination using marking papers.A simple and reliable means of recording the results of an occlusal examination is important not only in relation to clinical dentistry but is also a consideration in dental research.
