Identification Of a Novel Anterior Survey Point on The Incisal Pin of The Hanau Semi-Adjustable Articulator for Occlusal Plane Establishment: An In Vitro Study
Keywords:
Incisal Pin, Occlusal Plane, lower canine, oral healthAbstract
The Occlusal plane is important in restoring the dental hard tissue with ordered pattern of occlusal contact and articulation to optimize oral function, occlusal stability, and aesthetics.
MATERIALS AND METHODS:
A total of 54 dentate subjects were divided into two groups. Maxillary and Mandibular primary impressions were made, and casts were obtained. Facebow records were made and transferred to Hanau Wide Veu Arcon semi adjustable articulator. Broadrick occlusal plane analyzer was attached to the upper member of the articulator, anterior and posterior survey points were obtained using lower canine as anterior survey point,distobuccal cusp tip of lower second molar (Group G1) and anterior point of condylar element (Group G2) as
two different posterior survey points to establish the occlusal plane. The deviation in the occlusal plane between two groups was measured. A four-inch radius arch was extended from the central survey point onto the incisal pin of the articulator, and the distance from the first annular ring was measured to determine an alternative anterior survey point.
