SERRANO, E.  e  MARTIN-GRANIZO, R.. Multicentric prospective study of MG-OSSEOUS implants at 2 year follow-up. Rev Esp Cirug Oral y Maxilofac [online]. 2009, vol.31, n.5, pp.295-308. ISSN 2173-9161.

Introduction. Implantology is the most common therapeutic procedure nowadays. Professor P.I. Branemark began this procedure in 1965 and got very bad results. Since the Harvard Consensus Conference, 30 years ago, showing and explaining the surprising criteria of the implant's survey, until now we have moved to the opposite side. All the rules are broken and they try to convince you by publishing some trials that are not scientific enough. We present this truly scientific trial using MG-OSSEOUS implants (Mozo- Grau SL, Valladolid, Spain) as a humble contribution, based on well defined and realistic clinical uses. Material and methods. The Spanish company Scientific Management in O&SS (Barcelona) designed a complete questionnaire to be completed by the implantologist dealing with each clinical case. The compilation and statistical processing were extremely rigorous. Data was managed, from the total rate of implants (N), to conclude if it was possible to obtain true data of different samples, and using ANOVA, to analyze selected parameters from these samples, in order to see the direct relation between them and the failure of the implants. Results. 1,475 dental implants were placed in 480 patients, between June 2005 and May 2006. The global implants success rate was 98.2% with an average of 2 years follow-up with the connected prostheses. The implants' position, length and diameter are detailed and the samples are also analyzed, as post extraction implants, immediate loading implants and implants associated with grafts. Discussion. We focused on, completing an exhaustive revision of actual bibliographical sources, the high failure rate obtained by the wide diameter implants (4,25 mm) post extraction and on the versatility of the strength diameter implants (3,4 mm) to be placed anywhere in the mouth, with no mean of the type of prosthesis associated. Conclusions. This trial can be defined as the philosophy's antithesis, in which we allow scientific and reproducible conclusions in implant surgery, our scientific truth. We will extend this trial to reach, at least, 5 years of follow-up.
