example 1

[0040] The selected incisors were corrected to a standard size with a root canal file, such that the remaining tooth walls of the tooth were of similar size. The tooth root was restored as shown below. Group 1 (15 teeth) - positive pole - no root filling. Group 2 (15 teeth) - The roots were filled with laterally concentrated gutta-percha and AH26 sealant. Group 3 (15 teeth) - Heel duct filled with vertical gutta-percha and AH26 root sealant. Group 4 (15 teeth) - root canal wall and self-etching device placed together, filled with root canal sealant and vertically filled with resin RESIN according to the invention. All roots were stored at 100% humidity for 2 weeks until strength testing, after which the teeth were fitted into plastic rings, leaving 8mm margin around the resin. This ring is fitted into the Instron device, in which there is a spherical appendage to create a wedge-shaped force on the long axis of the tooth. combined with image 3 and Figure 4 The reference...

example 2

[0044] A composition comprising polyacetolactone purchased from Union Carbide at a content of 40%, a bioactive glass having a composition similar to bioglass (purchased from US BIOMATERIALS) at a content of approximately 30%, USP grade Zinc Oxide at approximately 20% and Barium Oxide as a sunscreen at approximately 10%. The method of preparing the composition involves heating the polyacetolactone to approximately 70°C to a soft state. The remaining ingredients are added and mixed under kneading, extruding or mixing until the polyacetolactone is completely formed into a homogeneous dough. The resulting composition will be ready for use in a carrier device.

example 3

[0046] A composition comprising polyacetolactone in an amount of 30%, CMEE in an amount of about 10%, CAPROLACTONE 2-(METHACRYLOYLOXY) ETHYLESTER (CMEE) in an amount of about 10%, tricalcium phosphate in an amount of 30%, Zirconia content 10%. The method of preparing the composition involves heating the polyacetolactone to approximately 70°C to a soft state. The remaining ingredients are added and mixed under kneading, extruding or mixing until the polyacetolactone is completely formed into a homogeneous dough. The resulting composition will be ready for use in a carrier device.

Abstract

An dental filling material comprising a thermoplastic polymer. The thermoplastic polymer may be biodegradable. A bioactive substance may also be included in the filling material. The thermoplastic polymer acts as a matrix for the bioactive substance. The composition may include other polymeric resins, fillers, plasticizers and other additives typically used in dental materials. The filling material is used for the filing of root canals.

Description

field of invention [0001] The present invention relates to a filling material for cavity and root crimping catheterization. Background technique [0002] Endodontics and root catheterization are branches of dentistry that treat diseases of the tooth tissue. An aspect in endodontics that includes the treatment of infected apical ducts, excision of diseased pulp tissue, developed with the development of biomechanics and later filling of the pulp chamber (apical ducts). Treatment of root ducts portends that even teeth with a healthy external structure may be diseased, necrotic, or necrotic of pulp tissue. Such teeth have and or lack intact enamel and dentin, and these teeth are used for bone tissue. In such teeth, the pulp tissue and ex vivo parts of the root should be replaced with biologically acceptable substitutes. [0003] The process of making the heel duct involves opening a coronal access with a conventional dental drill. A tool used to remove medullary material fro...
