Benefits of technology

This patented composition described for use in treating teeth diseases involves combining two materials: guttape tip (a type called Gutta Peri) made from algae and an anti bacteric ingredient like nystatin A into one mixture. These compositions have better strength but also improve their ability to fight off plaque buildup on them compared to pure glue solutions alone. Additionally, they provide precise control over how much each component gets mixed together during application, resulting in improved results when applied topically onto hard tissue surfaces such as root cusps.

Problems solved by technology

This patented technical problem addressed in this patent relates to improving dentistry's ability to treat roots effectively while reducing failures caused by root clogging during medical procedures like endodontic therapy. Current methods involve injectable compositions containing liquid photopolyester resists and other chemical substances, making them challenged because they cannot completely mix well together without losing important properties.

Abstract

The invention belongs to the technical fields of manufacturing and applying of a DLP strengthened material and stomatology, and particularly relates to a gutta-percha tip composite. The gutta-percha tip composite comprises the following components in parts by weight of 5-20 parts of a modified developer, 5-20 parts of a modified antibacterial agent and 60-80 parts of photosensitive resin, whereinthe modified developer and the modified antibacterial agent are obtained through surface modification with a surface modifier. The gutta-percha tip composite is suitable for DLP printing, has favorable characteristics of favorable mechanical properties, favorable antibacterial effects and favorable biocompatibility, is high in production and processing precision, and can realize smooth printing. The gutta-percha tip composite can be widely applied to the biomedical science field, particularly the stomatology field. The root canal treatment accuracy can be improved, and a new way is provided for reduction of the failure rate of root canal treatment.
