Patent landscape report on dental implants: A technical analysis.

BACKGROUND AND PURPOSE Significant research and development (RD however, these have since been on the decline. Currently, the United States holds the largest number of patents, and Nobel Biocare Holding AG is the top assignee. Technic maturation prediction analysis showed that the current dental implant technology is in the "decline stage." CONCLUSION Trend analysis of the dental implant patent indicates the main contributors of development are profit-oriented companies. Recent reduction in the number of new patent applications suggests the technology is in the mature declining stage. The emergence of new materials or technologies that may close the gap in clinical unmet needs would reverse the trend.
