Comparación del Coeficiente de Estabilidad Implantaria ISQ entre implantes colocados en zona antral sobre hueso nativo frente a implantes colocados sobre hueso regenerado

Abstract

The objectives of the present study are to compare the Implant Stability Quotient (ISQ) values of implants placed in the antral area in native bone versus those placed on regenerated bone, to know whether after three months of osseointegration period the values increase and see if they are different from each other depending on the type of bone and assess the relationship between: insertion torque, type of bone and ISQ obtained an its changes after 3 months of osseointegration. The study design is a Clinical Trial of analytical purpose, whose temporal direction is longitudinal, the beginning of the study in relation to the chronology of the events is prospective. The results provide some evidence in the fact that implants placed in antral zone in regenerated bone, when presenting baseline ISQ values equal to and after osseointegration greater than implants in native bone, could be rehabilitated waiting for the implant. Conclusions: The initial ISQ value is similar in implants placed in native and regenerated bone and after three months were higher in implants placed in regenerated bone. The insertion torque of the implants placed in regenerated bone is greater than those placed in native bone and there is a positive relationship but not statistically significant between ISQ values and insertion torque. The marginal bone loss of the implants is similar in those placed in native versus regenerated bone and this loss is not related to ISQ values niether to insertion torque obtained. This fact is due to being evaluated in a short period of time.
