High accuracy

When you use a silicone or alginate imprint, there’s always a small risk that the material will expand during transport. However minor the deformity, it might create the need for another imprint… and another patient visit.

Using an intraoral scanner significantly optimises the fitting of Narval CC and limits the adjustments that need to be done at chairside. We evaluated 63 devices made from 3Shape digital imprints received from 7 different practitioners across Europe, and 95% of the devices were found to fit well even before practitioners made any adjustments. In fact, 90% of the devices did not require any adjustment on retention.1

1  IOS European Controlled Product Launch (CPL) – ResMed internal report, data on file (confidential) – January 2017- Chapters 4.2 (Summary from 92 manufactured IOS MRD), 4.3 (Patients and practitioners feedback from 63 questionnaires). Extracts from this ResMed internal report:
• 95% of the MRDs were fitting well in the patient's mouth, before practitioners did any adjustments.  
• There were no complaints or returns regarding retention.  
• 15 patients could compare their IOS MRD with their previous one: 80% of them declared that their new IOS MRD was more comfortable. The “previous MRD” can be any MRD, not only a Narval. In addition, 76% of 46 patients who had a conventional imprint in the past considered the digital imprint to be more comfortable than a conventional one.  
• 90% of patients found the IOS MRD comfortable or very comfortable.

Patient comfort

An intra-oral scanner takes up little space in a patient’s mouth, so limits gag reflexes and discomfort. With digital imprints, only 6% of the patients experienced a gag reflex.
