Abstract

OBJECTIVE:

The claims in some dental implant marketing brochures may lack strong supporting evidence. The objective of this review was to examine peer-reviewed literature to assess the strength of evidence to support selected claims, to help clinicians in making evidence-based decisions.

METHODS:

The claims proposed by Astra Tech, Straumann, 3i and Nobel Biocare, all companies with a significant market presence, were examined. A PubMed database search was conducted using the following limits- English language, RCT, Meta- analysis, 1970-2006. Selective searching using the Cochrane database and Google Scholar was performed up to 2008 for searches that had exhibited no outcomes with the PubMed search. We performed quantitative and qualitative analysis of these RCTs and assessed if the claims could be supported by these RCTs.

RESULTS:

The data were extremely heterogeneous, making comparisons difficult. The majority of the included RCTs were rated as having low risk of bias. Some of the claims proposed by the companies could not be completely substantiated on the basis of the relevant literature.

CONCLUSIONS:

Future studies should follow the guidelines as stated in the CONSORT statement to enable standardisation and comparison across different implant systems.
