An evaluation and adjustment method for natural proximal contacts of crowns using diamond dental strips: a case report.
The best way to adjust proximal contacts of newly fabricated indirect restorations has been a long-standing unresolved issue in dentistry. Excessively tight contacts cause incomplete seating of indirect restorations and intrusion of adjacent teeth, which leads to patient discomfort, hypersensitivity, and recurrent dental caries at the crown margins. When seating indirect restorations, interproximal relief should be restored as it exists in natural dentition. This article presents an innovative method of crown seating using diamond strips. This simple, consistent, method makes it easier for clinicians to provide comfortable and long-lasting restorations with minimal time and effort. Laboratory technicians utilize diamond strips to provide properly fitting indirect restorations that require minimal adjustment upon clinical delivery. Diamond strips also allow for accurate determination of heavier proximal contacts, allowing dentists to adjust the proximal contact properly in the patients' mouths. Clinically, restoring natural proximal contacts is a critical factor to the success of indirect restorations. Using this method standardizes proper proximal contact adjustments of laboratory-fabricated indirect restorations between dental labs and dental offices. The method also helps to limit or eliminate the lingering proximal contact issue between clinicians and laboratory technicians.
