Comparison of Dental Arch Measurements Between Stone and Digital Casts

F. Garino, MD, Ortho Sp1, G.B. Garino, MD, DDS, Ortho Sp1

Pages: 250-254

Editor’s Note: Perhaps the most significant advance in orthodontic diagnosis for the new millennium is the use of 3-dimensional diagnosis. In cephalometrics, orthodontics was literally 2-dimensional for over 50 years, as the transverse dimension was ignored—even though posteroanterior or frontal headplates could be taken on the same cephalometer, and Broadbent demonstrated their value as early as 1931, in his seminal article in the Angle Orthodontist. Sam Weinstein once commented, “We are a generation of profiles!” Threedimensional programs now produce superb results for photographs and cephalometric film or digital images, and these programs are rapidly becoming a primary diagnostic assessment. The traditional plaster study cast, however, has been so firmly entrenched in our diagnostic armamentarium that clinicians have been slow to change to computerized replicas, fearing that the multiple decisions made might be compromised by computer renditions of dental arches. This fine paper on comparison of dental arch measurements between stone and digital casts will be reassuring to all clinicians who question the ease of use, accuracy, permanence of records, communication with other dentists, and preparation of scientific papers, etc. The potential of digital images of casts is clearly evident and transcends the information from plaster or stone replicas. The additional advantage of saving storage space is a welcome advance. Ask any orthodontist who has been in practice for a number of years about storage! Orthodontists are urged to investigate this important advance for honing our diagnostic and prognostic skills. Several programs are available, and all are being constantly improved. Diagnosis is the name of the game now, more than ever, in an increasingly litigious environment.—T.M. Graber
