Cellulose Cyanoacrylate and Method of Employment

Cellulose cyanoacrylate is employed to bond two surfaces, fill voids or duplicate the shape of a three-dimensional object, Two surfaces may be bonded by placing a sheet of cellulose material between the surfaces and applying cyanoacrylate glue around the edge of the sheet until saturated and allowing it to cure. Paper toweling may favorably be employed as the cellulose material. A break or fracture in an article can be overlaid with a sheet of cellulose that when saturated with cyanoacrylate glue and temporarily held in place and shaped with a releasable film, the fracture can be corrected. A dry powder comprising highly abrasion-resistant particles can be mixed with the cellulose material to enhance abrasion resistance and to improve long-term color stability—especially important for dental cavity treatment. To duplicate the shape of a three-dimensional object, a sheet of releasable film is placed over the object, followed by a sheet of cellulose that is then saturated with cyanoacrylate glue. A sheet of releasable film is then placed over the cellulose and used to hold the cellulose in place and shape it as it hardens.

Independent claims are also included for method of identifying the shape of dentures, and for a device for carrying out the method. The fibers (14) are inserted into the form and cast in plastics. The form is fabricated by first establishing the shape of a residual zone of teeth and a duplicate replacement section (42) is generated and stored as digital data (DD).

Method of implantation of the artificial tooth

FIELD: machine building. SUBSTANCE: invention relates to medicine, namely, to dentistry. For this, the alveolus is treated and an artificial tooth made of hydroxyapatite is injected into it, the root of which is first applied with a layer of nutrient medium with cementoblasts. Above the layer of the nutrient medium with cementoblast, a layer of nutrient medium with fibroblasts is applied in such a way that they do not mix these cell layers. Thickening agent is added to the nutrient media. Between the layer of nutrient medium with cementoblasts and a layer of nutrient medium with fibroblasts, a resorbable membrane is placed and/or nutrient media with various densities are used. Method provides an increase in the affinity of an artificial tooth with biological tissues and an improvement in its survival, a decrease in the probability of bacterial multiplication in the tooth region and, as a consequence, the elimination of an unpleasant odor, the formation of a correct supporting tooth (bone-periodont-cement-root) and, as a consequence, an increase in the damping effect, an increase in the possibility of reparative processes, as well as reducing the time of treatment by decreasing the time interval from the moment of removal of the tooth to the moment of engraftment of the artificial tooth. After this, the tooth is fixed. EFFECT: invention may be used to implant an artificial tooth. 3 cl, 1 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) (19) RU (11) (13) 2 649 452 C1 (51) МПК A61C 13/08 (2006.01) A61C 13/23 (2006.01) A61K 6/033 (2006.01) A61K 35/32 (2015.01) A61K 35/33 (2015.01) A61K 38/39 (2006.01) A61P 1/02 (2006.01) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ На основании пункта 1 статьи 1366 части четвертой Гражданского кодекса Российской Федерации патентообладатель обязуется заключить договор об отчуждении патента на условиях, соответствующих установившейся практике, с любым гражданином Российской Федерации или российским юридическим лицом, ...
