Occasionally, absolutely healthy teeth are traumatized to the extent that they must be extracted. The use of cylindrical endosseous implants as single-tooth replacements is gaining acceptance. The case of a healthy young adult who suffered a traumatic injury that rendered his maxillary left central and lateral incisors nonrestorable is reviewed.
