Abstract
Purpose: Maxillomandibular residual ridge relationship is one of the important pieces of information in prosthodontic treatment. However, visual examination of the casts on the articulator has been the only way that could easily be achieved in daily clinics. We have developed a simple method for the examination of maxillomandibular residual ridge relationship using digital image processing.
Materials and methods: Standardized digital pictures of the upper and lower casts were taken using the indicator that was made to define the location, direction, and size of the picture. The standardized digital pictures were processed on a personal computer. The occlusal map that is the digital image that exactly reproduces the maxillomandibular residual ridge relationship is composed using digital processing software (Adobe Photoshop and so forth).
Discussion: The occlusal map shows the image of the maxillomandibular residual ridge relationship viewing through the direction perpendicular to the occlusal plane. It is important information for prosthodontic treatment, and consequently the occlusal map is informative for the prosthodontic treatment planning and artifical tooth arrangement.
Conclusion: Scientific and simple methods of analysis for the maxillomandibular residual ridge relationship was developed. The occusal map provides useful information to dentists and dental technicians for the planning of prosthodontic treatment and artificial tooth arrangement.
