Abstract: A system for capturing and displaying an image of an entire oral cavity includes a handheld intraoral camera and a computer processor. Each of left and right panoramic tooth row images is generated by combining a first digital still image including the center of the front teeth with a second digital still image taken adjacent to the first digital still image and having an overlapping portion with the first digital still image, to form a first combined image. This step is repeated until a last digital still image positioned at the back tooth of the respective row is combined with a last combined image, forming the left or right panoramic tooth row image. The left and right panoramic tooth row images are superposed in an area of the center of the front teeth to form the full panoramic tooth row image.

Abstract: A dental implant including a columnar core member and a covering layer which is covered over at least part of the outer circumferential surface of the core member and which is comprised of recrystallized apatite-based ceramic, wherein the covering layer is comprised of a hydrothermal treated layer of a plasma spray-deposited covering which is formed by spraying a plasma of a composite containing at least two types of calcium phosphate-based compounds which differ in melting point at the outer circumferential surface of the core member based on the melting point of the low melting point calcium phosphate-based compound among the calcium phosphate-based compounds. This dental implant is provided with a strength enabling it to sufficiently withstand a chewing force over a long period of time and with a fast bondability and affinity with the gum and furthermore is excellent in extraction strength as well.

Abstract: Provided is a security box including: an input means for input of external data; an execution means for executing, in a predetermined area, external data input by the input means; and an isolation control means for isolating the execution area from other areas during execution. The security box can be further equipped with: a display means for displaying the behavior of external data executed by the execution means; a determination means for determining, on the basis of the behavior displayed by the display means, whether the external data is normal data; and a deletion means for deleting data that the determination mean has determined is not normal data and/or all of the data of the execution means.

The measuring and machining unit is connected to the external operating unit by communication, and the measuring and machining unit can be operated from the outside.

Abstract: Spherical-shape ceramics obtained by dropping starting ceramics into a low temperature medium or composite spherical-shape ceramics having a composite layer obtained by applying a hydrothermal treatment thereto.

Abstract: A method of manufacturing a dental prosthesis includes the steps of obtaining shape data of a portion to be prosthetically treated and shape data of a surface condition after it is prosthetically treated, obtaining shape data of a prosthesis from the two shape data sets, obtaining contour data of a portion of the prosthesis contacting a tissue of a living body and appearing outward, and converting the shape data of the prosthesis into a cutting data assuming that a connecting rib is to be connected to the prosthesis at a region appearing outward on the shape data of the prosthesis and substantially not contained in the contour data. Also, the present invention provides a method of placing and object and a measuring device.

Abstract: An iontophoretic interface comprising a non-electroconductive material of a porous or capillary structure, coated and treated with a disinfecting and preserving ionic surfactant on the portion of the surface coming into contact with the drug as well as a skin pre-treatment composition and a skin pre-treatment method.

Abstract: A blood-collecting device includes a suction device for suctioning and thereby swelling a portion of a patient's skin by decompression so that a movable paracentetic needle can be driven into the swollen skin to puncture the skin. Once the skin has been punctured, the paracentetic needle is withdrawn while suction is maintained on the swollen skin in order to draw a blood sample from the patient.

Abstract: A bioimbedding material comprising a mixture of ultrafine hydroxyapatite powder having a particle size of 2 .mu.m or less, and a polymer or oligomer, which can function as a tissue substitute for a long time in a living organism, without causing inflammation, which has flexibility and elasticity, which has an excellent biocompatibility and contrast, and which does not require a contrast line, and a process for producing the same.

Abstract: An electrode system for administration of a pharmaceutical by iontophoresis which is comprised of an electroconductive substrate and a functional polymer having ammonium hydroxide or a quaternary ammonium halogen salt, sulfonic group, carboxylic group, amine group.

Abstract: A data-protection system which permits authorized users to use a target data through a simple operation but does not permit unauthorized users to use the program even though they may be able to copy it.

Abstract: A blood-collecting device comprising a decompression chamber, a suction cell with paracentetic means, and paracentesis-terminating means. Simple and painless blood collection is made possible.

Abstract: A high purity .alpha.-tricalcium phosphate ceramic having a superior biocompatibility for use mainly as a bone filler, is produced by shaping a powder material formed by a wet method, followed by sintering it and then cooling at a predetermined rate.

Abstract: A cosmetic composition containing triglyceride oleate and yeast extract and further, if desired, an L-cysteine hydrochloride as components for proliferating indigenous bacteria on the skin.
