Prospective clinical human trials, published in English from January 1997 to July 2011, that examined dental implants of <10 mm with a 12-month follow-up were included in this meta-analysis. The following data were retrieved from the included articles: the number of implants, implant dimensions, implant locations, types of prostheses, follow-up periods, and implant survival rates. Kaplan-Meier survival estimates and the hazard rates were analyzed and compared between short and standard implants. </p><p> <strong>Results:</strong> Thirteen studies were selected, examining 1,955 dental implants, of which 914 were short implants. Short dental implants had an estimated survival rate of 88.1% at 168 months, when standard dental implants had a similar estimated survival rate of 86.7% (P = 0.254). The peak failure rate of short dental implants was found to occur between 4 and 6 years of function. This occurred at an earlier time point compared with standard dental implants, where the peak failure rate occurred between 6 and 8 years of function. </p><p> <strong>Conclusions:</strong> This study shows that in the long term, implants of <10 mm are as predictable as longer implants. However, they fail at an earlier stage compared with standard implants. </p><hr><p></p><p> <strong>Source: </strong>Journal of Periodentology </p><p> <a href="http://www.joponline.org/doi/abs/10.1902/jop.2012.120328" target="_blank"><font color="#0000ff">Full Text</font></a></p> Alveolar bone loss, dental implants, evidence-based dentistry, longitudinal studies, survival rate 0 0 http://idai.ir/browse.php?a_code=A-10-32-1323&slc_lang=en&sid=1 Alberto Monje 10031947532846005890 10031947532846005890 No Department of Periodontics and Oral Medicine, School of Dentistry, University of Michigan, Ann Arbor, MI Hsun-Liang Chan 10031947532846005891 10031947532846005891 No Department of Periodontics and Oral Medicine, School of Dentistry, University of Michigan, Ann Arbor, MI Jia-Hui Fu 10031947532846005892 10031947532846005892 No Department of Periodontics, Faculty of Dentistry, National University of Singapore, Singapore Fernando Suarez 10031947532846005893 10031947532846005893 No Department of Periodontics and Oral Medicine, School of Dentistry, University of Michigan, Ann Arbor, MI Pablo Galindo-Moreno 10031947532846005894 10031947532846005894 No Department of Oral Surgery, University of Granada, Granada, Spain Hom-Lay Wang homlay@umich.edu 10031947532846005895 10031947532846005895 Yes Department of Periodontics and Oral Medicine, School of Dentistry, University of Michigan, Ann Arbor, MI
