Morrison Root Screw for Manual Extraction  is a specialized dental instrument used in oral surgery for the extraction of teeth, particularly roots or broken teeth. This screw features a 3mm diameter and is designed with a threaded tip to securely engage with the root or fragment of the tooth. By applying rotational force, the screw aids in loosening and extracting the tooth or root from the surrounding bone and tissue. This manual extraction tool is particularly useful in cases where traditional forceps may not provide sufficient grip or leverage, enabling dentists to perform extractions with precision and minimal trauma to the surrounding structures.
