Patent analysis reveals dental implant technology is in a mature decline, with fewer applications filed recently. Innovation in new materials or technologies is needed to revitalize the field and address unmet clinical needs.

Area of Science:

Biomaterials and Medical Device Engineering
Intellectual Property Law
Dental Science

Background:

Extensive research and development (R&D) has focused on advancing dental implant technology, evidenced by numerous patent filings.
Understanding the patent landscape is crucial for identifying R&D trajectories and market dynamics in the dental implant sector.

Purpose of the Study:

To evaluate the current patent status of dental implants.
To identify future R&D directions for dental implant innovation.

Main Methods:

A comprehensive review of 29,711 dental implant-related patents filed between 1909 and 2020.
Patents were categorized by component: fixture, abutment, and artificial teeth.
Analysis included patent trends, assignees, citations, and technology maturation prediction.

Keywords:

dental implant development patent research technology

Main Results:

The 'abutment' category showed the highest patent activity, with 'screw-type dental implant anchor' being the most cited patent.
Global patent applications peaked in the early 2010s and have since declined.
The United States leads in patent ownership, Nobel Biocare Holding AG is the top assignee, and current technology is in the 'decline stage' of maturation.

Conclusions:

Profit-driven companies are primary developers in the dental implant field.
The declining trend in patent applications suggests market maturity and potential stagnation.
Novel materials or technologies addressing clinical gaps are essential to stimulate future growth and reverse the current trend.
