Failure to utilize a diagnostic cast
during prosthodontic treatment planning will result in an improper and inadequate treatment outcome.
Impressions with irreversible hydrocolloid were made to obtain diagnostic casts
from Type III dental stone and the casts mounted on a semi-adjustable articulator (Hanau Wide Vue) using a face-bow transfer (Fig.
, preimplant prosthodontics, treatment prostheses, and surgical templates.
were duplicated and mounted in a semiadjustable articulator (model 2240; Whip Mix Corp, Louisville, KY) at the vertical dimension of occlusion (VDO).
All of the 6 maxillary anterior teeth present, anatomically whole, without restorations that altered their dimensions, from which good diagnostic casts
could be obtained, and where the anatomic elements were well dened were included in the study.
