Abstract

Prosthetic restorations through implants were popularized, and they became routine treatments. Small accessories used in the implant prosthodontic procedure are more likely to slip or fall off the dentist's hands. If the dental appliance or material passes into the upper gastrointestinal tract, there is a high possibility of excretion to the outside of the body without complications, but serious complications may occur depending on the type of foreign body. If the foreign body is passed to the airway, it is an emergency situation, and if it is not done properly, it can be fatal. The purpose of this review report is to investigate the process of foreign body ingestion or aspiration during dental treatment, and the method of prevention and treatment.

  Fig. 1 Phase of swallowing. (A) Tongue moves upwards and backwards against hard and soft palate to push the bolus into the oropharynx, (B) Pushing the bolus into the pharynx. Movement of the bolus into the pharynx stimulates receptors in the oropharynx. Soft palate and uvula close off nasopharynx, (C) Epiglottis seal off the larynx. This prevents bolus from entering the respiratory tract. The upper esophageal sphincter relaxes, allowing the bolus to move into the esophagus, (D) The upper esophageal sphincter contracts to reduce backflow into the pharynx.
