Una técnica ortodóntica-quirúrgica facilita la expansión en la sutura media palatina del maxilar en pacientes adultos. En este procedimiento se realiza una corticotomía en el maxilar y se utiliza un tornillo Hyrax para conseguir la expansión. La separación de la sutura se confirma con una radiografía oclusal y por la presencia de un diastema entre los incisivos centrales del maxilar.

Palabras clave: Expansión rápida palatina; tornillo Hyrax


A combination of an orthodontic appliance and a surgical technique makes easy the expansion of the palatine maxilar suture in adults. In this procedure a maxilar corticotomy is done; and a Hyrax screw is used to obtain the expansion. The separation of the suture is confirmed by taking an oclussal X-ray, and it is also confirmed observing the separation of the maxillary central upper incisors.

Key words: Fast palatine expansion; Hyrax screw
