ジャーナル フリーThe purpose of this study was to investigate the structure and the function of the part of the mandible where mylohyoid muscle originates.
The bundle bone in the area of mylohyoid line and the tendon fibers on the surface of the bundle bone were observed by light microscopy and scanning and transmission electron microscopy.
The conclusions were as follows:
1. It seemed that remodeling occurs frequently in bundle bone in the area of the mylohyoid line.
2. Sharpey's fibers in bundle bone in the area of the mylohyoid line seemed to be flexible. This suggested that Sharpey's fibers can be adapted to the tension from directions that are different to a certain degree.
3. Both directions of Sharpey's fibers in bundle bone in the area of the mylohyoid line and the tendon fibers on the surface of bundle bone were fundamentally the same as that of the muscle fibers of the mylohyoid muscle. But a few existing fibers crossed these fibers. Such Sharpey's fibers and tendon fibers seemed to prevent the exfoliation of the periosteum, and seemed to support main tendon fibers of the mylohyoid muscle when it is contracting.抄録全体を表示PDF形式でダウンロード (36937K) -

ジャーナル フリーThe purpose of this study was to characterize the biochemical and immunological properties of the temporomandibular joint (TMJ) . Proteoglycans (PGs) were extracted from the porcine TMJ retrodiscal tissue (RT) and superficial fibrous layer of condyle (SLC) . The proportion of Glycosaminoglycans (GAGS) with TMJ disc, RT and SLC resembled that of disc and RT GAGs, but SLC GAGs were different from others. TMJ disc had a higher Dermatan sulfate / Chondroitin sulfate ratio than that of RT, and TMJ disc had stronger tensional load resistance than that of RT. Immunologically, a high molecular weight PG resembled Aggrecan and two low moleculaer weight PGs resembled Decorin and Biglycan.
Total RNA was isolated from SLC, and RT-PCR was performed. These products were sequenced, and these sequences were compared to the sequences of porcine Aggrecan, human Decorin and Biglycan. These results suggested that TMJ had Decorin, Biglycan, and Aggrecan. The difference of PG quantity in each region seemed to be associated with the pathological conditions found on each component of TMJ.抄録全体を表示PDF形式でダウンロード (6045K) -

ジャーナル フリーThe purpose of this study was to investigate the influence of sex and age on the selection of color, size, and form of anterior teeth for complete dentures.
A sample representing one hundred eighty-five edentulous patients whose complete dentures were made with Real Crown teeth (Shofu Inc.) was obtained.
The results were as follows:
1) Lighter teeth were selected for females than males, but age had no relation to the selected color of the teeth.
2) Larger teeth were selected for males than females, but age had no relation to the selected size of the teeth.
3) The combination and tapering forms were selected frequently, the combination form was used more frequently for females than males and the tapering form was used more frequently for males than females.抄録全体を表示PDF形式でダウンロード (545K) -

ジャーナル フリーThe aim of this study was to evaluate the influence of occlusal deficit by loss of bilateral posterior molars in masticatory habituation and how to improve by RPD, investigating the location center of occlusal load (by Prescale Fuji Film Co. ) and in its amount, in connection with masticatory muscle activities by analyzing EMG.
EMG measurements of masticatory masculature at maximal clenching with pressure indicator, were induced at intercuspal position, confirming by MKG.
As controls, seven complete dentate adults were referred, the five mandibular and maxillary bilateral molar-edentate cases each of five were investigated. The results were as follows
i ) The location of the center of the occlusal load in dentate mouth was about the midline of the maxillar first molar.
ii) In the loss of bilateral molars, the center of the occlusal load was in the first premolar area.
iii) By prosthodontic treatments the center of the occlusal load was changed to the second premolar area.
iv) These results indicated that the prosthodontic treatment was estimated in physiological imperfection of recovery as yet dentate mouth.抄録全体を表示PDF形式でダウンロード (2156K) -

ジャーナル フリーThe dental study cast has a complicated shape. Therefore, many dead angles are recognized during three-dimensional (3-D) measurement using a light source. To overcome this problem, several divisional measurement methods have been developed. However, in these methods, inadequate accuracy and the discontinuity of data were observed on the reconstructed image. In this study, a new divisional measurement method was developed and the overall accuracy was evaluated. The standardized stone model, which has three spheres, was kept by the specifically designed high precision jig. The distances between the reference points of each sphere were measured by using a 3-D curved shape measurement apparatus with a laser source. Then the values were compared with those obtained by using a contact type 3-D measurement apparatus.
There were slight differences between the two methods, but they were not statistically significant. In addition, when the individual data were combined, the distances between the reference points of each sphere were not significantly different. These results suggested that the shape of the study cast can be accurately measured by the divisional measurement method抄録全体を表示PDF形式でダウンロード (6559K) -
