Resumen

MALPARTIDA-CARRILLO, Violeta; TINEDO-LOPEZ, Pedro Luis; GUERRERO, Maria Eugenia  y  ORTIZ-CULCA, Fernando. The influence of cortical perforations on guided bone regeneration: A literature review. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2019, vol.12, n.1, pp.37-40. ISSN 0719-0107.  http://dx.doi.org/10.4067/S0719-01072019000100037.

Objective:

To evaluate the influence of cortical perforations on guided bone regeneration (ROG) by histomorphometry results obtained from human and animal studies.

Review of current literature:

An electronic search of trials in humans and animals with histomorphometric evaluations was carried out in the PubMed, Cochrane Library, SciELO and Google Scholar databases from 1980 to May 2017. The following search strategy was used: ((decortication of bone) OR (bone decortication) OR (alveolar decortication) OR (decortication) OR (decortications) OR (cortical perforation of bone) OR (cortical bone perforation) OR (cortical perforation) OR (cortical perforations) OR (intramarrow penetration) OR (marrow penetration)) AND ((guided bone regeneration) OR (guided bone augmentation) OR (bone augmentation) OR (osseous repair) OR (graft integration)).

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.
