Dental Devices

by Tim B Hunter, MD, MSc and Rick Light, DDS



Dental devices are not usually considered orthopedic devices. Dentists and orthopedic surgeons ordinarily do not operate on or treat the same parts of the body. Dental devices are used to maintain dental health and treat dental disease. The most common dental "apparatus" is dental amalgam which is used to fill cavities caused by tooth decay. Besides dental amalgam, dental devices also include acrylic polymers, crowns, plates, screws, wires, dental and facial implants, and various devices for oral and facial reconstruction.

Oral and maxillofacial surgeons may do cosmetic dental surgery, reconstructive oral surgery, and temporomandibular joint (TMJ) surgery all of which impacts a portion of the musculoskeletal system. Facial and head and neck reconstruction may involve plastic surgeons, maxillofacial surgeons, general surgeons, neurosurgeons, and orthopedic surgeons in addition to dentists and dental surgeons in extreme cases where there is extensive surgical resection of the face, jaw, neck, and cervical spine because of widespread malignant neoplasm or severe traumatic injury.

Radiologists frequently encounter the teeth, mandible, and maxilla when interpreting head and neck images for trauma or infection or when evaluating orthopedic apparatus placed for cervical spine fixation and stabilization. Dental apparatus is not unimportant and is generally poorly understood and evaluated by most radiologists and other physicians. For this reason, a brief discussion of tooth anatomy and development, mandibular and maxillary facial and dental implants, and ordinary dental apparatus is presented.
