Development and Innovation on Dental Products in Argentina: A Technological Prospecting Based on Patents

Background: Argentina has progressed with industrialization in comparison to other Latin American countries and this process had a direct impact on the innovative capacity of the national economy. A constant search for market leadership, including the dentistry field and dental materials, stimulates the industries to launch new products daily. Inventions related to health researches are mostly protected by patents as intellectual property. A patent landscape analysis through searches in patent banks is a tool used to identify trends in different areas of innovations. Objective: This study aims to identify and evaluate the scenario of research, development and innovation of dental products in Argentina by a technological prospecting based on patents. Methods: A survey of patent documents was conducted by searching for deposited and granted patents of dental products. The search was carried out during January 2020 in the patent database of the National Institute of Industrial Property of Argentina (INPI-AR). The terms “dentistry”, “buccal”, “dental” and “oral” were used to select the titles and abstracts of patent application reports. The information extracted from patent reports was organized in tables and Figs using Fig.Pad Prism 6 software to evaluate the applications. Results: A total of 363 patents were published from 1989 to 2016, mainly by international industries, 93.3% as patent invention and 3.0% as utility model applications on dentistry. Only two patents (0.5%) were deposited by universities, as the University of Melbourne (Patent number 20060102378) and Universidad Nacional del Nordeste (Patent number 20140104149), among which only the last one is national. Among the deposits, only 6.6% were granted; mostly were in force, denied or lost. According to the specialties, most patents were related to compositions (64.7%) and personal products (21.7%), also on dentistry/cariology (6.33%) and prostheses/implants (4.68%). Conclusion: In general, we find that most patent applications are related to the preventive area, personal products and compositions for formulations. Few dental patents deposits are currently available in Argentina, suggesting that the importation of products into the area remains large, which can make dental products more expensive. It is important to invest in technology-based companies to promote increased economic activity, being a consequence of an investment in knowledge creation and intellectual property to the Dentistry area.
