Anatomical study in relation to the implicated sites in the zygomatic implants technique
GONZALEZ E, Dámaso, SANZ R, Antonio and HIDALGO, Rodrigo
Abstract : The technique of zygomatic implants introduced by Branemark et al. (1997) in search of a simple solution for total maxillary toothless patients without a residual margin. The rate of success communicated by these authors was of 96.5%. The technique Branemark et al. describes, begins at the level of the palatine area of the 2° premolars crossing the alveolar margin toward the maxillary sinus and throughout the same toward the posterosuperior margin, obtaining the stabilization of the implant at that level. The present investigation was realized in complete cranium of the Department of Human Anatomy of the Dentistry Department of the Universidad Mayor, S antiago, Chile, during which bilateral measurements of the different bone structures affected in the zygomatic implant, with the purpose of determining the intra bone trajectory in this type of implant and its relation with the structures that it crosses. Independently of the type of cranium analyzed, the relation of the bone-implant contact in itstrajectory, is approximately one third of its longitude and it is determined that in an average distance of 40 mm or trajectory, no more than 10 to 12 mm of bone tissue is in contact with the implant
