Bone quality has been identified as an important factor for primary stability and maintenance of the survival rates of implants. A systematic review with meta-analysis was performed in order to assess the rate of survival of implants installed in low bone density (type IV) when compared to installed implants in bone tissues of regular density (type: I, II, III). The databases PubMed/MEDLINE, Web of Science, SciELO were used for article published until October 2016. A systematic review was adequate according to the requisites of PRISM, PICO question and scale bias was used (NHRMC). Relative risk of failure in implant failure level was performed considering 95% confidence interval. Fourteen studies were included involving a total of 1,869 patients and 8,370 implants. The main outcome, the meta-analysis indicated there is no difference in the survival rate of implants installed in type IV bone fabric vs. Type I (P = 0.23), type IV vs. Type II (P = 0.05), type IV vs. Type III (P = 0.24), as well as in comparing bone tissue soft vs. Hard type (P = 0.92), soft vs. Middle (P = 0.17). However, in the secondary outcome the meta-analysis indicated there is significant difference in survival rate of implants with machined surface installed in patients with type IV bone tissue (P = 0.003). Heterogeneity analysis showed low heterogeneity of the data. Based on randomized controlled clinical studies was not identified significant differences in the loss of dental implants installed in low bone density when compared to other densities. However, surface treatment is an important factor that can improve the survival rates of osseointegrated implants when was compared with surface implants machined, and noted also in the results that immediate loading in patients with type IV bone or soft bone densities can be a risk factor for the treatment
