The ability of the restorative dentist to communicate the location and orientation of the patient’s pertinent facial landmarks to the dental laboratory technician has great bearing on the esthetic success of final anterior dental restorations. This article describes a new device designed to facilitate this process. (J Prosthetic Dent 2001;86:173-6.)


The importance of incorporating facial considerations into the diagnosis and treatment planning of successful esthetic restorative dentistry has been explained in the dental literature.1-3 The inadequacies of using functionally oriented dental articulators and face-bows to record and transfer esthetic facial landmarks to the dental laboratory recently have been summarized by Chiche and Aoshima.4 Some articulator and face-bow systems can be very expensive, complicated, and difficult to understand, which leads to frustration and nonuse. An inexpensive alternative may not provide enough precision to properly restore the patient’s dentition.


Effective records should be made at both the diagnostic and the restorative phases of dental treatment; the easier and more precisely this can be performed, the more frequently it will be performed.5 The Facial Plane Relator (Ho Dental Products, Santa Barbara, Calif.) was developed to supplement, not replace, dental articulators or other face-bow devices. The clinician is encouraged to use any and all methods that clarify and complete communication to the dental laboratory. Three specific facial landmarks (the facial midline [FM], facial vertical axis [FV], and facial horizontal axis [FH]) and their dental counterparts (the dental midline [DM], dental vertical axis [DV], and dental horizontal axis [DH]) are the focus of this article and the new device described. We use these terms in dental esthetic examinations, diagnosis, and treatment planning. They are presented here to facilitate the descriptive use of the Facial Plane Relator. The purpose of the Facial Plane Relator is to give the dentist a relatively quick, simple method to transfer FM, FV, and FH locations to the dental laboratory technician before the fabrication of the dental restoration begins.
