161 results about "Luting agent" patented technology

A luting agent is an application of a dental cement. Luting agents connect an underlying tooth structure to a fixed prosthesis, hence giving rise to the term, luting agent, as they lute, or glue, two different structures together. There are two major purposes of luting agents in Dentistry – to secure a cast restoration in fixed prosthodontics (e.g. for use of retaining of an inlay, crowns, or bridges), and to keep orthodontic bands and appliances in situ.

Integral gutta percha core/cone obturation technique

An integral, one-piece silanated particle impregnated gutta percha core / cone technique employs a thin layer of a luting agent, such as glass ionomer cement with a machined gutta percha core / cone, precisely matches the preparation, thereby reducing leakage and achieving a hermetic seal. The hermetic seal is further enhanced by a mono-block bond that occurs between the silanated particles in the gutta percha and the appropriate chemical sealant. Optional cryogenic treatment of the gutta percha material changes its molecular weight, making it stiffer and conducive to forming an integral, one piece core / cone, without the need for a separate carrier core to install the tapered gutta percha core / cone within the root canal. Additionally, the tapered body of the core / cone may be reticulated in a slightly three dimensional texturized framework to increase surface area and therefore increase retention. Optional line demarcation indicia are also placed on the core / cone. Additionally, the head of the core / cone can be gripped by a delivery vehicle clasp.
