Evaluation of the measurement precision and accuracy in the dental CAD/CAM system

The purpose of this study is to investigate the precision and trueness of the occlusal contact record obtained with a dental CAD/CAM device (ARCTICA). Sandblasted spherical steel balls with diameters of 10-20 mm were measured using ARCTICA and a three-dimensional measurement device (FN503). The radius of each steel ball was calculated from the measured value and the difference between the measured and nominal values was obtained. Upper/lower dental arch casts were measured and processed for occlusal contact image creation using both devices. The graphical images of the occlusal contacts at the intercuspal position obtained from both systems and an occlusal analysis device (BE-1) were compared with the occlusal contact area. Excellent correlation was observed between the measurement results of ARCTICA and FN503 (p<0.001, R: 0.99). The occlusal contact areas were 186.0 mm (ARCTICA), 192.8 mm (FN503), and 196.1 mm (BE-1). This study showed that ARCTICA is capable of conducting highly accurate measurements and generating a graphical image of occlusal contacts with good reliability.


Relationship between Frontal/Lateral Mandibular Translations and Masticatory Movement Based on Evaluation of Occlusal Surface Motion

Objective: This study aimed to clarify whether crown restorations with adjusted occlusal surfaces that were formed using frontal/lateral mandibular translations, functioned without interference during mastication.
Materials and Methods: In 10 adult volunteers who had healthy normal dentition, frontal and lateral border movement was measured during unilateral mastication and free mastication, using an ultrasound digital mandibular measuring system (ARCUS digma2). Additionally, precise impressions of the upper and lower dental arch were taken, and dental casts were made. These casts were measured using a CAD/CAM scanning system (ARCTICA). For the fabrication of crown restorations, the functionally generated path technique (FGP technique) was used on the monitor for the lower first and second molar. The movement of the opposite teeth on the occlusal surface during frontal and lateral border movement, during unilateral mastication, and during free mastication was considered the functional occlusal surface. The data of the functional occlusal surface generated by frontal/lateral mandibular translations and that of each of the masticatory functional occlusal surfaces were superimposed using three-dimensional data evaluation software (GOM). The difference between these surfaces was evaluated to determine the interference area, maximum interference difference, and average interference difference.
Results: Interference was present for all functional occlusal surfaces created by mastication as well as those determined by frontal/lateral mandibular translations. The average interference values, in order of free masticatory movement, habitual masticatory side, and non-habitual masticatory side, were as follows. Interference area: 167.5 ± 20.8 mm2, 121.9 ± 28.5 mm2, 144.6 ± 28.0 mm2; maximum interference distance: 345.0 ± 43.1 m, 189.0 ± 39.9 m, 309.0 ± 46.8 m; average interference distance: 130.0 ± 15.7 m, 64.0 ± 10.6 m, 130.0 ± 21.9 m. Statistically significant differences were found for the maximum interference distance and average interference distance (both p < 0.05).
Conclusions: The functional occlusal surfaces for each form of mastication demonstrated interference with the functional surface of frontal/lateral mandibular translations. Thus, crown restorations of which the occlusal surfaces were adjusted and formed by frontal/lateral mandibular translations may interfere with mastication.


Development of an oral assessment sheet for evaluating older adults in nursing homes

A new general use oral assessment sheet (OAS), comprising three items each in three categories (i.e., oral hygiene, biting and chewing, and oral function), was developed to improve the oral health of older adults requiring nursing care. Seventy-nine care workers used the assessment sheet to evaluate oral conditions in 188 institutionalized older adults. Forty-five care workers and three dental professionals then assessed oral conditions in 45 institutionalized older adults using the test-retest method before and after dental professional guidance. Cronbach's alpha of the OAS was 0.72, and 0.65, 0.57, and 0.82 for the three subcategories of oral hygiene, biting and chewing, and oral function, respectively. After dental professional intervention, absolute and relative agreement coefficients increased to more than 0.6 and 0.89, respectively. Reliability and validity of the OAS were verified, and difficulties in oral assessment experienced by care workers were identified. [Res Gerontol Nurs. 2017; 10(5):234-239.].


Case report of recurrent temporomandibular joint open lock associated with abrupt reduction of displaced articular disk

This report describes the case of a 51-year-old male patient who initially presented at age 23 with a habitual intermittent open lock (at >35mm) in the left temporomandibular joint (TMJ). The patient was able to manage this affliction through rapid-repetition jaw opening and closing. Tomography of the joint showed no irregular morphology, but intraoral examination revealed an occlusal interference at the mandibular left third molar during leftwards excursion. For this patient, alteration of lateral guidance using a palatal plate attached to the maxillary left canine precluded this intermittent open lock, but at 22 years of age, the open lock recurred and could not be relieved by the patient, who was unable to assume an occlusal position. Because conservative treatment was ineffective, a pumping manipulation technique was applied to reduce the open lock, after which the patient has maintained good jaw function. MRI taken before and after repositioning indicated that abrupt reduction of a displaced articular disk was the cause of the open lock, and that this articular disk was restored to its proper position during the manipulation. Most TMJ open locks occur as anterior dislocation, where the mandibular head becomes trapped anterior to the articular eminences, causing excessive opening and difficulty closing. Our clinical findings from this patient indicate that open lock can occur through abrupt reduction of a displaced articular disk, particularly in patients with chronic internal derangement of the TMJ. TMJ open lock can occur following abrupt reduction of a displaced articular disk.

A hospital-based survey of TMD patients at Tokushima University Hospital

徳島大学病院における顎関節症患者の特徴に関する調査-男女比，年齢構成と受診期間-

Objective: The purpose of this research was to clarify the characteristics of TMD patients at Tokushima University Hospital and to investigate the effects of clinical sampling bias. Materials and Methods: Recorded data of selected TMD patients (1,083 cases, average age 39.2±19.4, male : female=1 : 2.4) from the TMD report system in the digital chart system of the hospital and new patients of Tokushima University Hospital Dental Division (24,588 cases, average age 43.0±23.5, male : female=1 : 1.4) were analyzed in terms of the age distribution, the male to female ratio and the treatment period. Results: The male to female ratio of both groups was significantly different (chi-square test: p<0.001). The age distribution of TMD patients was bimodal. Peak age groups were 15-24 and 55-59 years old. In comparison with the new patients group, there were many TMD patients among the 15-34 year-old group, but few in the 60-84 year-old group. On the contrary, the age distributions were different from those of the general population in Tokushima prefecture (Population Census 2005, Ministry of Internal Affairs and Communications), particularly among the middle aged. This comparison indicated that the bimodal age distribution of TMD patients might reflect a sampling bias of the clinic-based sample. For example, the limited office hours for outpatient care of the university hospital might result in a socio-economic bias for working-age patients and cause an apparent bimodal distribution. Regarding treatment period, about 80% of patients completed regular outpatient treatment within 90 days and about 90% of patients completed it within 180 days. On the other hand, there were 52 cases (4.8% of 1,083 cases) who received outpatient treatment for more than 1 year. Conclusion: The characteristics of TMD patients at Tokushima University Hospital were investigated, including the effects of clinical sampling bias.

Investigation on the Allergic Condition among the Dental Professionals


An allergy survey among dental professionals

Purpose: Medical materials in clinical settings could function as risk factors that cause allergic symptoms. This issue is particularly relevant to dental professionals because they are exposed to various allergens. The objective of the present study is to conduct an allergy survey among dental professionals and clarify the actual prevalence and other parameters of allergies.Methods: An anonymous questionnaire was distributed to employees and dental students working at the University of Tokushima Dental Hospital (currently, the Department of Dentistry, Tokushima University Hospital).Results: Valid responses were obtained from 294 individuals (145 males and 149 females). The average age of the respondents was 34.0 years. Of the respondents, 61.2% had experienced some subjective symptoms associated with allergy. The most common allergic symptom was allergic rhinitis (40.1%), and 20.4% of the respondents perceived themselves to be allergic to medical gloves.Conclusion: The study results indicated that the prevalence of subjective allergic symptoms was higher among dental professionals than among the general public or other healthcare professionals. This suggests that dental professionals work in an environment where they are likely to be sensitized to different allergens.


スパイラルCTを用いた顎関節の三次元評価法

スパイラルCTを用いた顎関節の三次元評価法

Three-dimensional (3-D) image reconstructed from Computed Tomography (CT) data is an ef>cient method to evaluate temporomandibular joint (TMJ) morphologically. Even the 3-D image reconstructed from spiral CT data has some distortion, typically along to the table feed direction, very few studies were reported about accuracy of reconstructed 3-D image size. The purpose of this research was to evaluate the distortion on 3-D image reconstructed with spiral CT (Somatom Plas4, Siemens Co, Germany) quantitatively. We used three imaging targets, eight ceramic balls placed at corners of cubic frame, a calibration cube that has the CT value nearly equal to cortex bone of human dried mandibular head. We evaluated relation between a threshold level of CT image processing and reconstructed 3-D image size with a custom-made computer program. CT data of ceramic balls clari>ed changes of the reconstructed image, -0.215mm for table feed direction and less than ±0.006mm for the other directions. The calibration cube was used for the arrangement of optimal scanning condition (reconstruction mode, collimation, reconstitution interval) and evaluation of reconstructed image size. The distortion of the image was +0.207mm for table feed direction and less than +0.029mm for the other directions. Changes of dried skull TMJ image reconstructed with the optimal scanning condition were -1.463mm for lateral direction of the condylar head, -0.956mm for back and forth direction and -0.580mm for table feed direction. Results of this research suggested that the level of the 3-D image distortion was mostly affected with the scanning condition. And the size of 3-D image was susceptible to the threshold level of CT image processing. Consequently, we think that the standardization of scanning condition should be concerned for the quantitative evaluation of 3-D TMJ image using CT data.


Development of a novel articulator that reproduced jaw movement with six-degree-of-freedom

A novel robotic articulator that reproduced a six-degree-of-freedom jaw movement was developed and tested. A precise six-axis micro-positioning stage was employed for this articulator. A high-resolution jaw-tracking device measured the functional jaw movement of the patient and a six-axis micro-positioning stage reproduced recorded jaw movement data. A full veneer crown restoration was fabricated with this articulator system. A working cast was mounted on the positioning stage of the articulator. An occlusal table with soft wax was attached on the cast tooth die, and the jaw movements were reproduced to create a functionally generated path on the occlusal table. The finished occlusal record was used to obtain the wax pattern for the crown. In this subject, no intra-oral occlusal adjustment was necessary for setting the finished full veneer crown. Since this articulator could perform a precise reproduction of the dynamic jaw motion during the functional jaw movement, this system has potential to improve accuracy of the prosthetic teeth occlusion.


Relationship between occlusal tooth contactpatterns and tightness of proximal tooth contact

The aim of this study was to investigate the relationship between occlusal tooth contact patterns and the tightness of proximal tooth contact (TPTC) during clenching. Twenty young adult volunteers with healthy dentition participated in the study. TPTC between the left second premolar (P2) and the first molar (M1) was measured during clenching at the 50% maximum voluntary contraction level in the intercuspal position (ICP). A silicone impression material was used to make an interocclusal record at the ICP in each subject, and interocclusal records were analysed using an image-processing system. Subjects were classified according to the presence or absence of each type (A, B or C) of occlusal contact. Statistical analysis was performed using the Mann-Whitney U-test. The results of this study exhibited a relationship between B-type contact and the TPTC of maxillary teeth. The experimental group with a lack of B-type contact on maxillary P2 and/or M1 showed a statistically greater TPTC than the group with B-type contact on both of these teeth (P < 0.01). These results suggest that occlusal tooth contact patterns have an influence on TPTC during clenching.

Evaluation of proximal tooth contact tightness at rest and during clenching

The aims of this study were to develop a device for measuring the tightness of proximal tooth contact and to evaluate the proximal contact tightness using this device at rest and during clenching. Twenty young adult volunteers with healthy dentition participated in this experiment. The tightness of proximal tooth contact between the second premolar and the first molar of both the maxilla and the mandible was measured by pulling a stainless steel strip between them at rest, and at 20 and 50% clenching levels of maximum voluntary contraction of masseter muscles at intercuspal position. Proximal contact tightness increased as the clenching levels of both the maxilla and the mandible increased. At rest, proximal contact tightness was less in the maxilla than in the mandible, whereas during clenching it was less in the mandible. These results indicate that during clenching, the teeth are displaced and they contact appropriately with adjacent teeth, making it possible to exert sufficient occlusal force while maintaining the integrity of dental arches.


Effects of occlusal force loading on tooth movement in six degrees of freedom --- Development of an analysis system

The purpose of this research was to evaluate tooth movement in six degrees of freedom under occlusal force loading. The right side upper first premolar movement of an adult volunteer without any signs or symptoms of periodontal disease was studied. A small occlusal table mounted on a force transducer was clipped between the upper and lower dentition. Occlusal force was applied to the buccal cusp, palatal cusp or central fossa of the first premolar and also to the right side canine aspect by clenching this occlusal table. The right side first premolar movement relative to the left side first premolar was measured by means of a highresolution six degrees of freedom motion detector. The three-dimensional shape of the first premolar was measured with following methods. A 3-D digitizer with a touch sensor probe was used to measure the coronal part of a cast stone model of the tooth. Computerized tomography data were used to obtain the root shape of the tooth. These movement and configuration data were combined to perform computer graphics analysis of the three-dimensional tooth movements. The range and direction of tooth movement were varied by altering the position and amplitude of occlusal force loading. Since the magnitude of the tooth movements was relatively small, we adapted the screw axis (helical axis) concept to emphasize tooth movement on the computer graphics representations.

Quantitative study of bite force during sleep associated bruxism

Nocturnal bite force during sleep associated bruxism was measured in 10 subjects. Hard acrylic dental appliances were fabricated for the upper and lower dentitions of each subject. Miniature strain-gauge transducers were mounted to the upper dental appliance at the right and left first molar regions. In addition, thin metal plates that contact the strain-gauge transducers were attached to the lower dental appliance. After a 1-week familiarization with the appliances, nocturnal bite force was measured for three nights at the home of each subject. From the 30 recordings, 499 bruxism events that met the definition criteria were selected. The above described system was also used to measure the maximum voluntary bite forces during the daytime. The mean amplitude of detected bruxism events was 22.5 kgf (s.d. 13.0 kgf) and the mean duration was 7.1 s (s.d. 5.3 s). The highest amplitude of nocturnal bite force in individual subjects was 42.3 kgf (15.6-81.2 kgf). Maximum voluntary bite force during the daytime was 79.0 kgf (51.8-99.7 kgf) and the mean ratio of nocturnal/daytime maximum bite force was 53.1% (17.3-111.6%). These data indicate that nocturnal bite force during bruxism can exceed the amplitude of maximum voluntary bite force during the daytime.
