Introduction
The following case study demonstrates how to create bite splints for your patients using the ERKOPRESS ES-200 E and ERKODENT thermoforming discs. Providing bruxing and clenching splints can be one of the most rewarding treatments in dentistry today. You'll get your patients out of pain quickly and reduce further tooth destruction.
Figure #1 After diagnosis of bruxism, instruct the patient to close into centric relation to verify midline position and bite.
-
Figure #2
Place 2 cotton rolls behind the cuspids and instruct the patient to close until resistance is felt.
-
Figure #3
You could also place softened wax over the anterior molars and have the patient close to the desired 3 mm opening.
-
Figure #4
With patient closed into this open bite, inject bite registration into the posterior openings of both quadrants.
-
Figure #5
Then inject bite registration material into the anterior opening to capture a complete open construction bite.
-
Figure #6
Using a properly fitting impression tray, take upper and lower alginate impressions using correct water/powder ratios.
-
Figure #7
Upper and lower models with bite mounted in place. Note open bite between anterior teeth.
-
Figure #8
The upper or lower model is used in the ERKOFORM to thermoform the splint and create the flat bite table.
-
Figure #9
After thermoforming, the splint is trimmed and polished with carbide burs, felt wheels and acrylic polish.
-
Figure #10
Seat the splint and evaluate fit, retention and occlusion. Adjust with carbide bur and polish if necessary.
-
Figure #11
After completely seating splint, check bite using marking tape to identify any premature occlusion.
-
Figure #12
Instruct the patient to care for his or her splint by rinsing with water after every use and storing dry.
