Autotransplantation of a maxillary first premolar to replace an ankylosed maxillary incisor: 7-year follow-up

In young patients, premature tooth loss in the anterior maxilla after trauma is challenging for the patient and the dental professional, with serious implications from aesthetic and functional points of view, as well as from a craniofacial growth aspect perspective. Premolars autotransplanted into the maxillary anterior region have been shown to be a biological alternative in this situation. This report describes the clinical management of a case of premature loss of a maxillary central incisor after traumatic injury. A mandibular premolar at the stage of initial root development was transplanted into the alveolar socket of the lost incisor. After 18 years, the transplanted tooth remained responsive to pulp sensibility tests and the periradicular bone and soft tissues were within normal limits. Autotransplantation of premolar teeth into the maxilla could be considered an excellent treatment choice with many biological advantages over implants or fixed dentures as long as proper case selection is followed.

“…The use of calcium hydroxide as an intracanal dressing is required as part of the endodontic treatment because the high pH and antimicrobial properties of this compound may contribute to the prevention of root resorption and stimulation of the healing process (9,10,13,17). In this case, a calcium hydroxide dressing was used in addition to the already described properties to stimulate the process of apical closure.…”

“…Autotransplantation is defined as the transplantation of teeth from one site to another in the same individual into extraction sites or surgically prepared sockets (10). The advantages of autotransplantation include the possibility of maintaining the viability of the periodontal ligament, orthodontic movement and proprioception, and preservation of the alveolar bone and gingival graft with a natural contour.…”

Autotransplantation of a Mandibular Third Molar: A Case Report with 5 Years of Follow-up

et al. 2013

This paper describes the autologous transplantation of a mandibular right third molar to replace the residual roots of the second molar in the same quadrant, preserving function and aesthetics. A 5-year clinical and radiographic follow-up was undertaken. After transplantation, the donor tooth received endodontic treatment and placement of calcium hydroxide, which was periodically replaced every 3 months until the filling of the root canals, totalizing a period of 1-year, when apical closure was confirmed. The tooth was in perfect functional and aesthetic conditions 5 years after beginning of treatment. Autotransplantation is a feasible option for replacing missing teeth when a donor tooth is available. The autotransplantation of a right mandibular third molar with compromised function and aesthetics to replace the residual roots resulting from coronal destruction due to extensive carious lesion of the second molar in the same quadrant was a viable treatment alternative.

“…Dharmani et al (53) presented a case of a 17-year-old male 1-week post-trauma to tooth 12 where a horizontal root fracture was diagnosed and given a poor prognosis. This group noted the need to surgically resect the buccal root of the premolar, fill the resected root with composite, dress the palatal root with calcium hydroxide for 2 months, complete root canal treatment, and then initiate orthodontics (54). Upon a 2-year recall, the tooth was judged esthetic and functional (53).…”

“…Tsurumachi and Kuno (54) discussed autotransplantation of a maxillary premolar after extraction of an ankylosed incisor. This group noted the need to surgically resect the buccal root of the premolar, fill the resected root with composite, dress the palatal root with calcium hydroxide for 2 months, complete root canal treatment, and then initiate orthodontics (54). The predictability of autotransplantation has been further discussed regarding its acceptable esthetic and clinical surrogate measure outcomes by Czochrowska (55)(56)(57).…”

One of the options for management of severely traumatized dentitions is to provide immediate implant placement with immediate loading. Three representative cases out of 15 patients with 23 traumatized teeth treated to date in our clinic are presented. None had labial bone fractures. The teeth were replaced with NobelReplace Groovy implants (Nobel Biocare, Gothenburg, Sweden) in the fresh sockets immediately after extraction. They were placed toward the palatal areas in the sockets and 3 mm below the gingival margins. If there were gaps between implants and sockets wider than 1 mm, particulate deproteinized bovine bone was grafted in the gaps. Immediately after placement, the implants were loaded with provisional prostheses. The final restorations were installed 3-4 months later. The patients were reevaluated clinically and radiographically 1-3 years after the final restorations had been placed. In all 15 patients, excellent functional and esthetic results were achieved. No implants showed radiolucency, peri-implant suppuration, or mobility. The patients were satisfied with the results. Immediate implant placement with immediate loading is an option that provides good treatment outcomes and allows good functional and esthetic results, as well as addressing the social/psychological aspects of dental trauma.
