Evaluación estructural del implante dental sometido a diferentes torques de inserción. Estudio "in vitro"

Abstract

El material más frecuentemente utilizado en la implatología oral en la es el titanio comercialmente puro, ya que presenta una gran biocompatibilidad y constituye el material ideal para conseguir la osteointegración con éxito a largo plazo tras la carga funcional

HIPÓTESIS DE TRABAJO: Las diferentes hipótesis nulas que se plantearon con respecto a la relación de las diferentes variables observadas en nuestro estudio fueron las siguientes: 1.Ho:Fuerzas superiores a 80Nw/cm2 no presentarían ni deformidades,ni alteraciones en la superficie de los implantes de conexión externa ni en los de conexión interna. 2.Ho:Fuerzas superiores a 90Nw/cm2 no presentarían deformidades, ni alteración en la superficie, ni fisuras en los implantes de conexión externa ni en los de conexión interna. 3.Ho:Fuerzas superiores a 100Nw/cm2 no presentarían deformidades en el transportador del implante, ni alteraciones en los hexágonos de los implantes de conexión externa ni en los de conexión interna...Surgical and prosthetic procedures necessary for this purpose have evolved in the constant need to achieve more effective and satisfactory rehabilitations for patients. In this context, dental implants arise as a therapeutic option with which a firm anchoring of the pontics or prosthesis to the bone and to the tissues is obtained. Oral implantology has revolutionized the dental clinical practice showing that the oral rehabilitation of patients with single, multiple or total tooth loss dental implant is a predictable treatment and with a high rate of success. The replacement of missing teeth underwent a revolution many years ago with the advent of osseointegrated implants - the possibility of replacing missing teeth in the mouth without grinding the remaining teeth or treatment of free-ends with fixed prosthesis represented a significant advance in the quality of the treatments that we can offer to our patients. Over the years, the technique of implant placement and subsequently prosthesis on implants, is more common in the treatment of edentulous to the point that begins to be considered the treatment of choice to propose to the patient. On the other hand, must take into account that the treatment of the unitary absence of a tooth, the cost to the patient of an implant and a crown, is next to the cost of a three-unit bridge. The increase of implant-supported treatments have caused that the implants have become an habitual activity in dental clinics, which requires that the technique of placing these implants have to be increasingly foreseeable considering the essential requirements of an operation to implant placement...
