Abstract
La estabilidad primaria en los implantes se considera un prerrequisito deseable para la obtención de la estabilidad biológica o secundaria, siendo esta el resultado de la formación de hueso nuevo en contacto con su superficie. Por otro lado, el mantenimiento del hueso marginal periimplantario en la posición más coronal posible, es un factor clave para el éxito a largo plazo, además de favorecer la estabilidad del entorno gingival.
OBJETIVOS: 1.- Determinar el efecto de distintos parámetros relacionados con el implante, el paciente y el tipo de hueso en la estabilidad primaria y secundaria medida mediante el torque de inserción (IT) y el coeficiente de estabilidad del implante (ISQ primaria, ISQ secundaria); así como la interrelación entre ellos.
2.- Analizar la pérdida ósea crestal (CBL) y la pérdida ósea marginal (MBL) periimplantaria en implantes yuxtacrestales y subcrestales, desde el momento de colocación hasta finalizado el período de 3 años de seguimiento; así como determinar si las pérdidas ósea crestal y marginal están relacionadas con la estabilidad del implante- torque de inserción, ISQ primaria e ISQ secundaria- y con diferentes parámetros relacionados tanto con el implante como con el paciente: longitud, diámetro, tipo de hueso, localización y sexo...
Primary stability in implants is considered a desirable prerequisite for obtaining biological or secondary stability, this being the result of the formation of new bone in contact with its surface. On the other hand, maintaining the peri-implant marginal bone in the most coronal possible position is a key factor for long-term success, as well as favouring the stability of the gingival environment. OBJECTIVES: 1.- To determine the effect of different parameters related to the implant, the patient and the type of bone on primary and secondary stability measured by means of the insertion torque (IT) and the coefficient of stability of the implant (primary ISQ, secondary ISQ); as well as the interrelationship between them. 2.- To analyze the crestal bone loss (CBL) and the peri-implant marginal bone loss (MBL) in equicrestal and subcrestal implants, from the moment of placement until the end of the 3-year follow-up period; as well as to determine if the crestal and marginal bone losses are related to the stability of the implant - insertion torque, primary ISQ and secondary ISQ - and to different parameters related to both the implant and the patient: length, diameter, type of bone, location and sex...
