Recently occlusion becomes a topic in dentistry. The occlusal rehabilitation cases which are restored for many teeth on one time, are doing in daily dentistry. For occlusal rehabilitation, the occlusal relationship of patient's mouth should be exactly reproduced on articulator. The occlusal balances on restration which are given on articulator, should be caused as same as on articulator and in patient mouth is most important to keep gnatho-stomatologic syseem healthy. The reappearance of upper cast on articulator by face-bow transfer procedures are tested on T.M.J. articulator (using true hinge points), Dentatus articulator (using arbitrary condyle points) and Whip-mix articulator (using auditory meatus). The measurements are done on our developed three dimensional gnathometer. Face-bow transfers are done from a manikin and a dental student who does'nt have any problemes in tempolomandibular joints, teeth and periodontium. An experienced operator of this face-bow transfer is the author and an unexperienced operator of this procedure is used a dental student. Three face-bowes are tested in this study. The data are compared between a manikin and a patient, and between an experienced operator and an unexperienced operator. The following conclusion are obtained :I) The results of face-bow transfer on manikin, the reappearance of upper cast on articulator are arranged in superior orders as follow ; T.M.J. articulator > Whip-mix articulator > Dentatus articulator. 2) The results of face-bow transfers on human subject by an experienced operator, the reappearance of upper cast on articulator are arranged in superior orders as follow ; T.M.J. articulator > Whip-mix articulator > Dentatus articulator. 3) The results of face-bow transfer on human subject by an unexperienced operator, the reappearance of upper cast on articulator are arranged in superior orders as follow ; Whip-mix articulator > T.M.J. articulator > Dentatus articulator. 4) The results of face-bow transfer on manikin by an experienced operator are always superior reappearance than the results on human subject. The reappearance of upper cast on articulator are arranged in superior orders as follow ; T.M.J. articulator > Whip-mix articulator > Dentatus articulator. 5) The results of face-bow transfer on human subject by an experienced operator are always superior than the results by an inexperienced operator. The reappearance of upper cast on articulator by an experienced operator are arranged in superior orders as follow : T.M.J. articulator > Whip-mix articulator > Dentatus articulator. The reappearance of upper cast on articulator by an unexperienced operator are arranged in superior orders as follow : Whip-mix articulator > T.M.J. articulator > Dentatus articulator.
