Separation of overlapping dental arch objects using digital records of illuminated plaster casts
BACKGROUND Plaster casts of individual patients are important for orthodontic specialists during the treatment process and their analysis is still a standard diagnostical tool. But the growing capabilities of information technology enable their replacement by digital models obtained by complex scanning systems. METHOD This paper presents the possibility of using a digital camera as a simple i...
متن کاملComparison of space analysis performed on plaster vs. digital dental casts applying Tanaka and Johnston's equation.
OBJECTIVE The purpose of this study was to compare dental size measurements, their reproducibility and the application of Tanaka and Johnston regression equation in predicting the size of canines and premolars on plaster and digital dental casts. METHODS Thirty plaster casts were scanned and digitized. Mesiodistal measurements of the teeth were then performed with a digital caliper on the pla...
متن کاملAutomatic 3D modeling of palatal plaster casts
This work introduces a procedure for automatic 3D modeling and discusses its performance in the context of a medical application, namely the 3D modeling of palate’s casts. The general interest of the proposed method lays in the fact that a widespread use of 3D modeling in non-engineering applications requires automatic procedures. The specific interest is in the intriguing mixture of open issue...
متن کاملExothermic properties of plaster–synthetic composite casts
PURPOSE Plaster casts can cause burns. Synthetic casts do not. Composite plaster-synthetic casts have not been thoroughly evaluated. This study analyzed the temperature from plaster casts compared with composite casts in a variety of in vitro conditions that would simulate clinical practice. METHODS A Pyrex cylinder filled with constant body temperature circulating water simulated a human ext...
متن کاملIntegration of digital dental casts in 3-dimensional facial photographs.
INTRODUCTION Since 1915, various researchers have tried to make a 3-dimensional (3D) model of the complete face, with the dentition in the anatomically correct position. This was a difficult and time-consuming process. With the introduction of 3D digital imaging of the face and dental casts, researchers have regained interest in this topic. The purpose of this technical report is to present a f...
