Is Bruxism a Risk Factor for Dental Implants? A Systematic Review of the Literature

I haven't read the original study but the abstract seems interesting. The authors attempt to answer a question that we all have asked ourselves at some time or another. But we still don't have a useful classification system for Bruxism or Parafunction that allows us to categorise patients in some clinically relevant fashion.....
If someone has access to the original paper I would appreciate if you could mail it to me !
Is Bruxism a Risk Factor for Dental Implants? A Systematic Review of the Literature:

Abstract

Purpose

To systematically review the literature on the role of bruxism as a risk factor for the different complications on dental implant-supported rehabilitations.

Material and Methods

A systematic search in the National Library of Medicine's Medline Database was performed to identify all peer-reviewed papers in the English literature assessing the role of bruxism, as diagnosed with any other diagnostic approach (i.e., clinical assessment, questionnaires, interviews, polysomnography, and electromyography), as a risk factor for biological (i.e., implant failure, implant mobility, and marginal bone loss) or mechanical (i.e., complications or failures of either prefabricated components or laboratory-fabricated suprastructures) complications on dental implant-supported rehabilitations. The selected articles were reviewed according to a structured summary of the articles in relation to four main issues, viz., “P” – patients/problem/population, “I” – intervention, “C” – comparison, and “O” – outcome.

Results

A total of 21 papers were included in the review and split into those assessing biological complications (n = 14) and those reporting mechanical complications (n = 7). In general, the specificity of the literature for bruxism diagnosis and for the study of the bruxism's effects on dental implants was low. From a biological viewpoint, bruxism was not related with implant failures in six papers, while results from the remaining eight studies did not allow drawing conclusions. As for mechanical complications, four of the seven studies yielded a positive relationship with bruxism.

Conclusions

Bruxism is unlikely to be a risk factor for biological complications around dental implants, while there are some suggestions that it may be a risk factor for mechanical complications.
