Replantation: Restoration of an organ or other structure to its original site.Tooth Replantation: Reinsertion of a tooth into the alveolus from which it was removed or otherwise lost.Amputation, Traumatic: Loss of a limb or other bodily appendage by accidental injury.Finger Injuries: General or unspecified injuries involving the fingers.Tooth Ankylosis: Solid fixation of a tooth resulting from fusion of the cementum and alveolar bone, with obliteration of the periodontal ligament. It is uncommon in the deciduous dentition and very rare in permanent teeth. (Jablonski's Dictionary of Dentistry, 1992)Tooth Avulsion: Partial or complete displacement of a tooth from its alveolar support. It is commonly the result of trauma. (From Boucher's Clinical Dental Terminology, 4th ed, p312)Microsurgery: The performance of surgical procedures with the aid of a microscope.Root Resorption: Resorption in which cementum or dentin is lost from the root of a tooth owing to cementoclastic or osteoclastic activity in conditions such as trauma of occlusion or neoplasms. (Dorland, 27th ed)Thumb: The first digit on the radial side of the hand which in humans lies opposite the other four.Incisor: Any of the eight frontal teeth (four maxillary and four mandibular) having a sharp incisal edge for cutting food and a single root, which occurs in man both as a deciduous and a permanent tooth. (Jablonski, Dictionary of Dentistry, 1992, p820)Dental Occlusion, Traumatic: An occlusion resulting in overstrain and injury to teeth, periodontal tissue, or other oral structures.Equipment Reuse: Further or repeated use of equipment, instruments, devices, or materials. It includes additional use regardless of the original intent of the producer as to disposability or durability. It does not include the repeated use of fluids or solutions.Periodontal Splints: Fixed or removable devices that join teeth together. They are used to repair teeth that are mobile as a result of PERIODONTITIS.Hand Injuries: General or unspecified injuries to the hand.Tooth Root: The part of a tooth from the neck to the apex, embedded in the alveolar process and covered with cementum. A root may be single or divided into several branches, usually identified by their relative position, e.g., lingual root or buccal root. Single-rooted teeth include mandibular first and second premolars and the maxillary second premolar teeth. The maxillary first premolar has two roots in most cases. Maxillary molars have three roots. (Jablonski, Dictionary of Dentistry, 1992, p690)Self Mutilation: The act of injuring one's own body to the extent of cutting off or permanently destroying a limb or other essential part of a body.Fingers: Four or five slender jointed digits in humans and primates, attached to each HAND.Maxilla: One of a pair of irregularly shaped bones that form the upper jaw. A maxillary bone provides tooth sockets for the superior teeth, forms part of the ORBIT, and contains the MAXILLARY SINUS.Penis: The external reproductive organ of males. It is composed of a mass of erectile tissue enclosed in three cylindrical fibrous compartments. Two of the three compartments, the corpus cavernosa, are placed side-by-side along the upper part of the organ. The third compartment below, the corpus spongiosum, houses the urethra.Reconstructive Surgical Procedures: Procedures used to reconstruct, restore, or improve defective, damaged, or missing structures.
