The field of dental medicine in medical technology or dental technology overlaps partly with oral, maxillofacial and facial surgery and ear, nose and throat medicine, but also with other fields, because pathological changes in the oral cavity can affect the rest of the body . Conversely, many diseases (e.g. blood disorders, cancer, infections) show symptoms, often as first symptoms in the oral cavity.
Dental medicine is concerned with the examination and treatment of the oral cavity. For this reason, many devices and delicate instruments are used by the dentist. While dentists and orthodontists have direct contact with the patient, dental technicians often work in a workshop or a dental laboratory. Dental technicians manufacture various types of dentures, dental fillings, braces, bite blocks and anti-snoring splints. They work directly with the dentists.
