Influencia del uso de injertos óseos asociados a corticotomía. Revisión Sistemática.

Abstract

ABSTRACT: Introduction: Corticotomy is a surgical procedure based on the Regional Acceleratory Phenomenon (RAP), whose objective is to reduce up to a third the time of orthodontic treatment. This technique can be performed adding a bone graft for the augmentation of the alveolar width and allowing a broader movement. This is known as Periodontally accelerated osteogenic orthodontics (PAOO). Objective: To determine the final condition of the buccal bone tissue after treatment in patients who received corticotomy and bone graft versus corticotomy alone. Materials and methods: An electronic search in the National Library of Medicine PUBMED was performed utilizing the following strategy: “orthodontics” OR “orthodontic treatment” and “osteotomy” OR “corticotomy” OR “periodontally accelerated” and “bone graft” OR “bone grafting” OR “augmented corticotomy” AND “tooth movement”. Risk of bias analysis was done utilizing the ROBINS-I tool. Results: The search yielded a total of 92 articles, of which 4 were considered for analysis. Conclusion: There is a limited number of studies regarding this topic and their risk of bias is moderate to high. Thus, the available evidence suggests that the use of bone graft and a resorbable membrane contributes to the improvement of the anatomical conditions, especially if the latter is fixed.
