Abstract

BALDERAS TAMEZ, Jonathan E.; ZILLI, Fabiola Neri; FANDINO, Luis Antonio  and  GUIZAR, Juan Manuel. Factors related to the success or failure of dental implants placed in the specialty prosthodontics and implantology at Universidad of La Salle Bajio. Rev Esp Cirug Oral y Maxilofac [online]. 2017, vol.39, n.2, pp.63-71. ISSN 2173-9161.  http://dx.doi.org/10.1016/j.maxilo.2016.02.001.

Introduction:

The dental implant therapy is a treatment that must require adequate surgical and prosthetic planning to avoid failures. Among the factors that influence success of the implants are the patient's condition, the characteristics of the recipient site and technology and the type of prosthetic rehabilitation.

Objective:

To identify factors contributing to the success or failure of implants placed in the Graduate Prosthodontics and Implantology at the University of La Salle Bajio.

Material and methods:

A total of 371 implants placed by residents of the graduate Prosthodontics and Implantology at the University of La Salle Bajio from 2010 to May 2014. To determine the factors associated with the placement a control sheet was made for each patient, where patient data, systemic condition, characteristics of the implant and the surgical procedures performed were described. To evaluate the results a statistical analysis of multiple logistic regression was performed.

Results:

Of the 371 implants placed, the failure of 19 implants before prosthetic phase occurred, obtaining a success rate of 95%. It was not observed that systemic patient's condition influenced the success of implants, however heavy smoking (more than 10 cigarettes a day) was significant (P = .0001). Other factors related to the failure trend were implant placement in flapless surgery (P = .02) and placement with a torque lower than 15 Nm (P = .0001).

Conclusions:

According to the data collected, this investigation showed that the risk factors for implant failure include smoking, little or no primary stability and flapless surgery.
