Implant complications are rare, but they can include nerve injury, bone loss, infection, injury to adjacent teeth and their supporting structures, premature loss of implants or the prosthesis fitted on the implant, bone fracture, and oroantral (ie, mouth, maxillary sinus) and oronasal (ie, mouth, nose) fistulae. Oral implants represent a new technological possibility. Whether it is used to replace a single tooth, several missing teeth, or an entire dentition, dental implants restore the feeling of having one's own natural teeth. This can improve the patient's physical and psychological health.
