Abstract
Background:It is a goal of restorative therapy to rehabilitate patients with lost or compromised dentitions and restore them to a functionally and esthetically acceptable level. Correct occlusal plane orientation is very important in prosthodontic reconstructive treatment and it should closely resemble to the lostocclusal plane. Gravity horizontal plane is that plane which is perpendicular to the gravity line. From literature it is evident that gravity horizontal plane is most parallel to the occlusal plane than other reference planes which are used routinely.Therefore, there was a need to construct a device to locate the gravity horizontal plane which would help in orienting the occlusal plane correctly.
Method: The study was conducted on 30 edentulous patients. A new device was fabricated to determine the gravity horizontal plane as a reference to restore the lost occlusal plane. Two sets of dentures were fabricated; one set by using camper’s plane as reference and second setby using gravity horizontal plane as reference. EMG activity of the patient was recorded after wearing both the sets of dentures.
Results: The dentures fabricated using gravity horizontal plane as reference were more satisfactory than the camper’s plane.
Conclusion: Gravity horizontal plane is a more reliable landmark than camper’s plane to restore the lost occlusal plane.
