INTRODUCTION: The purpose of this article is to propose a reference landmark for use in 3-dimensional cephalometric analysis with 3-dimensional volumetric images. METHODS: Cone-beam computerized tomographies were obtained from 10 adolescent patients. They were analyzed with AMIRA software (Mercury Computer Systems, Berlin, Germany). RESULTS: The proposed reference point is located between both foramina spinosum. CONCLUSION: This point has high intrareliability and is an adequate landmark for use as a reference in 3-dimensional cephalometric analysis.
