Oral Surgery
Cryer made several contributions to the field of oral and maxillofacial surgery. He is also known for developing the electrically operated surgical engine for cutting bone for jaw surgery and the spiral osteotome and guard for cranial surgery. In 1904, he designed forces to extract teeth during dental surgery. These tools specifically were universally designed for incisor and their roots. The two forceps were designed for upper and lower teeth. The left and right elevators also developed from his contributions. He initially made the two left and right scaling instruments for the scaling purposes and eventually he was able to use them to elevate dental roots.
