Three-Dimensional Reconstruction of Cone Beam Computed Tomography Using Splines Interpolation Technique for Dental Application¹

Dentistry deals with diagnosis and treatment of diseases in the oral cavity; dental radiography is a necessary tool for imaging the oral cavity as well as the maxillofacial region. The advancement of imaging technology in medicine has developed a method to visualize the volumetric information contained in a two-dimensional (2D) image. Cone beam computed tomography (CBCT) is usually used for imaging the maxillofacial region, for it provides effective information of the bone site. Dentist requires a 3D model of the maxillofacial region for both diagnosis and treatment. For treatment planning, the site must be imaged clearly so that they can visualize the volumetric information. CBCT imaging has more benefit than conventional imaging system [1,2]. Since it provides volumetric information of the site and also has lower radiation exposure, the physicians prefer CBCT imaging method. The proposed method for 3D model of teeth is to extract the...
