Prosthetics:  Complete Dentures: Designing Occlusal Registration Blocks to Save Clinical Time and Improve Accuracy

Feedback:  1 comment, 1 rating    


Abstract: The techniques described in this article are based on facial measurements and an analysis of the patient’s existing dentures to provide measurements that will enable registration blocks to be constructed for individual patients rather than the arbitrarily produced block more commonly seen. Employing the methods shown will lead to a saving in clinical time and contribute to a more accurate registration. It is important to remember that the technician can only provide occlusal registration blocks of the appropriate dimensions if the clinician has assessed the patient and existing dentures and then passed this information to the laboratory.

Clinical relevance: Being able to assess the clinical suitability of a patient’s existing dentures and then take measurements from those dentures will allow occlusal registration blocks to be constructed that have the correct dimensions and anatomical features for a particular patient. This will save time during the registration stage and help to improve accuracy.
