摘要:
Capsule (10) for two or more components of a material which are to be mixed together, comprising a cartridge (11) comprising an outlet (12), a first component chamber (13) for containing a first component, and a second component chamber (14) for containing a second component, the two chambers (13, 14) opening into the outlet (12); and a piston (15) which at least with its front end sits in the cartridge (11), lies with its rear end outside the component chambers (13, 14) and, when it is pushed forwards, presses the two components out of their component chambers (13, 14).
摘要:
The present application provides a delivery system for dental materials comprising a capsule having capsule body member and a capsule for dispensing material from said capsule body member, and an extension element, wherein the cannula and the extension element are adapted for a user-activatable unreleasable engagement with each other.
摘要:
Processes for forming dental materials that include applying a first hardenable dental composition (e.g., a dental adhesive) to a surface followed by applying a second hardenable dental composition (e.g., a dental composite) to the first hardenable dental composition on the surface. The first and second hardenable dental compositions are hardened such that the second hardenable composition is substantially completely hardened prior to complete hardening of the first hardenable composition.
摘要:
The present invention is directed to a plunger, a plunger assembly, and a system for storing a substance or substances, preferably flowable substances, and a method of filling and sealing a substance in a storing system. In particular, the present invention provides for substantially air-free filling and storing of substances in a delivery system.
摘要:
A dispensing device for a dental substance which has a container for receiving the dental substance, a piston movable in the container, a catch for engagement by an applicator, and further a resilient resilient adapter. The device may be used in different types of applicators and is relatively inexpensive.
摘要:
The present invention relates to a capsule for storage, mixing and dispensing of materials, preferably dental materials like glass ionomer cement. The capsule comprises a capsule body member that provides a main chamber and comprises a dispensing opening; and an applicator member being slideably accommodated in said capsule body member, said applicator member providing an auxiliary chamber. An activator member is slideably accommodated in said applicator member.
摘要:
The present invention is related to a device for providing a dental material. The device has first and second compartments formed between sheet-like layers, and first and second dispensing outlets for the first and second compartments, respectively. For use, the device can be positioned with the compartments overlapping each other and with the dispensing outlets located side by side. The invention may provide a rather inexpensive device which may help a user in a convenient preparation of a dental material.
摘要:
A system comprises an automatic mixing and dispensing device for a dental substance, and a material container. The mixing and dispensing device comprises a reservoir for receiving the dental substance, and first and second pressure plates. The material container has first and second material chambers for containing components of a material. The first and second material chambers have first and second cross-sectional chamber areas. At least one of the first and second cross-sectional chamber areas is smaller than smallest surface area of the first and second pressure plates. The system helps facilitating preparation and handling of dental materials.
摘要:
Provided is a device (10) for dispensing a dental substance. The device (10) comprises a cartridge (11) for containing the dental substance. The cartridge (11) has a plunger (20), and a dispensing opening (13). Further the device (10) is operable to urge the dental substance toward the dispensing opening (13). The device further comprises a cutter (31) for cutting off a portion of the dental substance which protrudes over the dispensing opening (13). The device may particularly facilitate precise dispensation of a high viscosity dental substance.
摘要:
This disclosure is directed, inter alia, a method of making a dispensing device for dispensing a substance comprising a step of providing a mold having a mold space for receiving a solidifyable material. The method further comprises steps of providing a valve member having a first portion formed between first and second areas of an outer surface of the valve member; placing the valve member into the mold space such that at the first area is isolated from the mold space and at least part of the second area is within the mold space; displacing the first portion at least partially relative to another portion of the valve member; and solidifying the material in the mold space and thereby fixing the displaced first portion in place. In one embodiment, the method helps minimizing manufacturing costs and maximizing shelf life of a device filled with substance.
