TL;DR: Although long-term results were favorable in many cases, resorption of the root was often seen and degeneration of vital elements followed and eventually produced a pulp that was replaced with a bonelike substance, both replants and transplants showed successful clinical results well beyond 2 years.

TL;DR: It seems, therefore, that replanted and autotransplanted teeth with open apices have a high potential for repair.

TL;DR: In the majority of the teeth observed after 180 days, the soft tissue of the pulp was markedly reduced in cells and blood vessels, and in a few teeth, the original pulp tissue seemed to have survived.

TL;DR: The aim of this paper is to underline the evidence based principles for successful autotransplantation and present the technique as a viable treatment option in present day orthodontic practice.
Abstract: Autotransplantation of teeth, if carried out successfully, ensures that alveolar bone volume is maintained due to physiological stimulation of the periodontal ligament. Autotransplantation has been carried out for many years, but with varying success rates. As a result, it is seldom regarded as an appropriate treatment option for patients with missing teeth especially with the continued development of osseo-integrated implants. Since placement of osseo-integrated implants in growing alveolar bone is contra-indicated, transplantation of available teeth remains a suitable choice for replacing missing units in the young patient. The role of autotransplantation of teeth in several clinical situations, the clinical techniques involved and factors influencing success of the transplant are discussed. The aim of this paper is to underline the evidence based principles for successful autotransplantation and present the technique as a viable treatment option in present day orthodontic practice.

TL;DR: Ankylosis persisted but a continuous remodeling process was taking place as evidenced by further resorption and bone formation until the end of the study (6 months).
Abstract: Thermal injury to the periodontium via the root canal was produced in 12 squirrel monkeys in order to study the sequence of events leading to ankylosis Three days and one week following such injury an area of necrosis was found in the periodontal ligament which was circumferential, involved both periodontal ligament and alveolar hone, extended approximately l/3 the length of the root and did not involve the epithelial attachment Two and 3 weeks following thermal injury new fibroblasts and blood vessels were seen at the periphery of neerotic areas and progressively decreased the area of necrosis This was accompanied by frontal resorption of bone and cementum Rear resorption took place adjacent to areas where the periodontal ligament was still neerotic By one month, healing had progressed so that neerotic tissue was no longer present, bone apposition was more prominant than resorption and in some areas tooth and bone had fused Ankylosis persisted but a continuous remodeling process was taking place as evidenced by further resorption and bone formation until the end of the study (6 months)

TL;DR: The hypothesis is offered that the epithelial remnants of Malassez play a role in the maintenance of the periodontal space and success or failure in replantation seems greatly to depend on the presence or absence of a vitalperiodontal membrane.

TL;DR: In this paper, the authors present a study of 22 Replanted Anterior Teeth in humans in the context of the Replantation of Teeth, and their role in this process.

TL;DR: The toothbud not only continues its characteristic development, but also exhibits the capacity to induce undifferentiated connective tissues to form bone.
Abstract: EXPERIMENTS by Charles B. Huggins and his associates, 1 and many others during the past thirty years, 2-11 demonstrate that whole toothbuds and parts of toothbuds possess the capacity to grow and develop in areas of the body other than the jawbone, even in the form of explants in tissue culture. The toothbud not only continues its characteristic development, but also exhibits the capacity to induce undifferentiated connective tissues to form bone. To explain these observations, Hoffman 12 postulates that the enamel organ and its derivative, Hertwig's epithelial root sheath, stimulates connective tissue cells to differentiate into bone cells, while Zussman 13 contends that odontoblasts which had previously participated in dentin formation can produce bone even when not in contact with oral tissues. Except that the new bone originates from proliferating living cells in both the transplanted tooth and in the host bed, present knowledge of the local physiology of

TL;DR: Intentional replantation—a seldom-used technic because root resection is generally preferred—involves extracting a tooth and reinserting it after treatment of the canals.
Abstract: Intentional replantation—a seldom-used technic because root resection is generally preferred—involves extracting a tooth and reinserting it after treatment of the canals. The procedure which is best done by two dentists, is described, along with its history, indications, contraindications, and an evaluation of the success or failure in 45 cases.
