Despite initial enthusiasm, blade implants have received bad press over the years due to fairly high failure rates reported in some publications of non-users. The aim is to discuss the techniques of blade implants to improve the understanding of the technique.

Materials and methods

A total of 522 blades were inserted in 20 years (1989–2009): 309 in females and 213 in males. The median age was 59 ± 11 years (min–max: 24–80 years).The implants were inserted in deep and atrophic narrow crests.


The success rate was 93.4% globally, 98.9% at 5 years, 89% at 8 years and 86.2% at 10 years.These data show very good results at 5 years, but slightly more failures at 8 and 10 years.


The blade implant is a valid therapeutic device useful for treating cases such as narrow bone crest and scarce spongy bone in the lower distal sector. They have demonstrated long-term survival. Nonetheless, to prevent failure, practitioners should be aware that blade implants are not indicated in wide alveolar crests or in areas where bone density is insufficient and that the implant cannot be positioned in the deep cortical layer.
