The influence of cortical perforations on guided bone regeneration: A literature review

Discussion and conclusion: Sixty five articles were identified and only 8 were selected. Four studies in animals showed statistically significant influence when performing cortical perforations. In 3 studies in animals and in 1 human study this difference was not statistically significant. However, when drilling, a greater number of blood vessels and a greater bone formation without inflammatory reactions or negative impacts were recorded. Cortical perforations show benefits in early stages of healing, influencing significantly in the angiogenesis, increasing the amount of neoformed bone.
