Abstract

MOYA-VILLAESCUSA, María José  and  SANCHEZ-PEREZ, Arturo Joaquín. Prognostic value of bone density and mobility in implant success. Rev Esp Cirug Oral y Maxilofac [online]. 2017, vol.39, n.3, pp.125-131. ISSN 2173-9161.  http://dx.doi.org/10.1016/j.maxilo.2016.10.005.

Purposes:

To prospectively analyze the prognosis value of the primary mobility (at the moment of implant insertion) and secondary (prosthetic phase), as well as bone density, in the implant success or failure after one year, five years and ten years.

Materials and methods:

Between 2005 and 2006, 151 implants were placed in 71 non-smoking patients. Primary (at the moment of surgery) and secondary (once osseointegrated) stabilities were measured in each implant through a Periotest® value (PTV) and the bone density was scored at the moment of implantation. One hundred nine of 151 implants placed initially completed the study.

Results:

There were no statistically significant differences regarding implant mobility at the moment of its insertion or once osseointegrated and the implant success or failure after 10 years. However, statistically significant differences were found respect to the bone density where the implant was placed after 5 and 10 years (P < .05).

Conclusions:

Primary or secondary mobility of the implant has no significant prognosis value on the implant success after 10 years. On the other hand, bone density has a clear influence on long time implant success. High density bones are more predictable to fail than low density bones after a long time.
