Abstract

To present an improved, accurate, and efficient method for planning and preparing an artificial socket for autotransplantation, by using a three-dimensional (3D) surgical guide and a replica of the transplanted donor tooth. The guide and the tooth replica were fabricated using a computerized 3D simulation. A case treated with this approach is presented. Cone beam computed tomography (CBCT) and computerized 3D simulations (Simplant plus registration as stereolithography) were used for planning the optimal artificial socket position and dimensions, within the limitations of the alveolar bone borders and the adjacent teeth roots, and for producing a metal replica of the transplanted tooth. The replica was used to assure the correct socket preparation and orientation before extraction and replantation of the donor premolar. The entire procedure time for autotransplantation of a permanent second premolar to the incisor site without the buccal plate was about 45 minutes. At 15 months' follow up, clinical examination of the transplanted tooth demonstrated both normal mobility and no sensitivity to cold stimulation. A radiographic examination revealed continuous root development and pulp obliteration. The adjacent teeth maintained thei...Continue Reading

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
