Name retrieval methods and name retrieval apparatuses that detect retrieval-target names that are representable as character strings including a ligature taking arbitrary property of a ligature into consideration in both a case where the ligature is input, and a case where the series of characters corresponding to the ligature is input, are provided so that convenience and reliability of name retrieval are improved. When a specific ligature is input, the specific ligature is converted into the series of characters corresponding to the specific ligature in accordance with the corresponding relationship TB stored in a storage device M, and specific retrieval-target names that include the series of characters obtained by the conversion in an input position of the specific ligature and an arrangement position of the series of characters corresponding to the number of coupled characters are retrieved from a database DB by character-string matching.

The invention relates to a beautifying appliance with functions of cleansing, massaging and skin caring. Most of existing beautifying cleansers are complex in structure and poor in effect. The beautifying appliance comprises a handle, a brush head and a center shaft, the brush head which is connected with the handle through the center shaft is in a roller shape and composed of a plurality of hair pieces, each hair piece is in a roller shape, a circular ring is arranged at the center of each hair piece, and a plurality of hairs are arranged on the periphery of each circular ring. The hair pieces of the brush head can be spaced each piece or multiple pieces by isolating pieces which can be circular, toothed or cam-shaped. The handle is Y-shaped, U-shaped or arc-shaped, the center shaft comprises a rotary shaft A and a rotary shaft B, and the rotary shaft A and the rotary shaft B are fixed with the handle through holes on the handle. The beautifying appliance integrates functions of cleansing, massaging, beautifying and skin caring, is simple in structure and convenient to use, can be used with cleansing supplies and the like for deep cleansing of skin, can be independently used as a massaging, beautifying and skin-caring appliance as well, is capable of promoting blood circulation and restoring the skin, and is good for popularization.

The invention discloses a dental implant structure, an assembly method thereof and a dental implant system. The dental implant system comprises the dental implant structure, wherein the dental implantstructure comprises an implant, a connecting piece and an abutment, a mounting groove is formed in the implant, the connecting piece comprises a connecting nut and an elastic piece which are arrangedin the mounting groove in sequence, a connecting screw rod in threaded fit with the connecting nut is formed at one end of the abutment, a first limiting part and a second limiting part which are matched with each other are arranged on the opposite sides of the implant and the abutment respectively, and the dental implant structure is assembled by matching two arc-shaped gaskets which are encircled into a ring. According to the invention, the connecting piece is arranged in the mounting groove of the implant, and the connecting piece enables the screwed abutment to have a movable gap along the axial direction through the cooperation of the slidable connecting nut and the elastic piece, so that the first limiting part on the implant is matched with the second limiting part on the abutmentto limit the rotation of the implant relative to the abutment.

The invention discloses a shell rotary-type clamping needle fixing dental implant structure and a use method, the shell rotary-type clamping needle fixing dental implant structure is used for alveolarbone, and the shell rotary-type clamping needle fixing dental implant structure comprises an implanting rod with an inserting hole formed along the axial direction; a inserting rod to be inserted into the inserting hole; a shell to be connected to the implanting rod in a sleeved mode and in threaded connection with the implanting rod; two clamping needles to be connected to the implanting rod through a second elastic piece, the two clamping needles are oppositely arranged, notches are formed in the opposite ends of the two clamping needles, and the second elastic piece is used for driving theclamping needles to move in the axis direction of the implanting rod; and the shell is used for driving the inserting rod to be inserted into the notches to drive the clamping needles to protrude from the peripheral wall of the shell. The shell is arranged for driving the clamping needles to be inserted into the alveolar bone, so that the dental implant structure is convenient to operate and use;due to the fact that the shell and the clamping needles are arranged, so that damage to the alveolar bone caused by screw-in of threads can be avoided when the dental implant structure is implanted;and the diameter of the arranged shell is larger than that of the implanting rod, thus being more convenient when driving.

The invention belongs to the technical field of articles for daily use and discloses an oral cleaning wet tissue. The oral cleaning wet tissue comprises a biodegradable base material and impregnation liquid. The biodegradable base material is made by weaving of cellulosic fibers and chitin fibers. The impregnation liquid is prepared from, by weight, 1-3 parts of glucolactone, 1-3 parts of maltose fatty acid ester, 10-20 parts of xylitol, 5-10 parts of mint leaves and 100 parts of purified water, wherein citric acid and sodium citrate adjust pH to 3.5-5.5. The oral cleaning wet tissue is effective in cleaning of bacteria and residues in oral cavity and can be used by infants due to safety and nontoxicity of components. By adoption of a biodegradable antibacterial wet tissue as the base material, the problem of bacterium resistance of the wet tissue is effectively solved while pressure caused by hard degradability of the wet tissue to the environment is relieved.

An oral device for checking a time to go to a dentist. The oral device includes a pH sensor configured to measure pH within an oral cavity, a housing on which the pH sensor is mounted, a processor configured to analyze measured pH from the pH sensor, and a wireless communication unit functionally connected to the processor and configured to perform communication with an external device. The oral device is useful for a patient who needs continuous management such as an implant surgery patient by allowing the patient to visually and easily check a time to go to a dentist and an individual oral condition of the patient. Further, by allowing the user to simply check the condition of the oral cavity at home, it is possible to more effectively manage the condition of the teeth and to save medical expenses.

The invention relates to an orthodontic auxiliary tool, in particular to an oral cavity restoration and correction tutoring device, which is characterized in that an anterior tooth positioning assembly comprises a first anterior tooth positioning piece and a second anterior tooth positioning piece; one ends of the two rear tooth positioning pieces are rotationally connected with the end parts of the first front tooth positioning piece and the second front tooth positioning piece respectively; the stretching mechanism is arranged on the rear tooth positioning piece; the oral cavity opening assembly is arranged between the two stretching assemblies, and drives the stretching assemblies to approach the throat when opening the oral cavity of the patient; and the administration assembly is arranged on the oral cavity opening assembly. Through the cooperation of the stretching assembly and the oral cavity opening assembly, when the device is placed in the oral cavity of a patient, discomfort cannot be generated, only when the oral cavity opening assembly opens the mouth of the patient, the stretching assembly can drive the oral cavity opening assembly to get close to the throat, and the situation that the patient feels uncomfortable when the device is placed in is avoided. In the process of opening the oral cavity, the dosing assembly sprays a medicament into the mouth of the patient.
