The Bi-Digital O-ring test is a diagnostic method in which the patient's physical condition is judged by his/her finger stregth. The patient is made to form a Bi-Digital ring using the thumb and any other finger on the same hand. The doctor then forms two of the same rings with his/her own hands, interlocking them with the patient's ring and then, While the patient using his own finger strength resists, the doctor attempts to pull open the ring from both sides using his own bi-digital o-rings. Diagnosis is made based on the patient's ability to maintain closure of the ring.
We apply this test to make diagnosis in the areas of conservative dentistry, prosthetic dentistry and oral surgery. It is a very useful method for occlusal diagnosis, determination of mandibular position and teatment and diagnosis of temporomandibular joint porblems. We would like to report on our objective observations and clinical cases.
