19 results about "Tooth loss" patented technology

Tooth loss is a process in which one or more teeth come loose and fall out. Tooth loss is normal for deciduous teeth (baby teeth), when they are replaced by a person's adult teeth. Otherwise, losing teeth is undesirable and is the result of injury or disease, such as dental avulsion, tooth decay, and gum disease. The condition of being toothless or missing one or more teeth is called edentulism.

A saw blade detection method and system based on multi-source data fusion

This invention discloses a saw blade detection method and system based on multi-source data fusion, specifically relating to the field of saw blade detection technology. By simultaneously acquiring high-speed visual images of the saw blade's front and side views and spindle current signals, the initial tooth profile reference features of the saw blade are extracted. Furthermore, the system monitors in real time changes in the straightness of the projection line, the amount of cutting edge retraction, and abnormal changes in the current signal during the saw blade cutting process. By fusing visual and current data analysis, the normal wear and degradation trend of the saw blade and abnormal tooth loss characteristics are observed, thereby achieving accurate identification of saw blade wear or tooth loss conditions. A comprehensive evaluation is then performed based on the defect rate of sawn products, ultimately outputting an accurate and reliable saw blade replacement control signal. This invention effectively improves the accuracy of saw blade condition detection and the timeliness of replacement decisions, avoiding processing quality problems and ensuring production efficiency and processing safety.
