Abstract: In this article, we discussed a rare case with 2 supernumerary teeth impacted in the horizontal plate of palatine bone and premaxilla, with emphasis on the choice of surgical approach and design of osteotomy lines to preserve normal anatomical morphology of premaxilla and protect adjacent teeth when extracted them contemporaneously with the application of piezosurgery. We also evaluated the clinical effect through clinical and imaging examination.
