Prior to preparing teeth, form a matrix on diagnostic casts
Many methods have been advocated for tempori- zation after full mouth tooth preparation to enhance esthetics function and muscular adaptation.4 Most of which are depending on articulated wax-up of the diagnostic cast
and construction of template or index in which a temporary resin material will be injected and placed over the prepared teeth.5
* Lower diagnostic cast
was surveyed, mouth preparation was done followed by functional impression using McLean's technique and resurveying.
The diagnostic cast
helps the dentist to evaluate the condition of the patient's oral condition and for the diagnostic purposes.
1 This study showed that the distance between the anterior attachment of the lingual frenum and the mandibular central incisor edge can be used on pre extraction diagnostic casts
as a pre extraction record for determining the occlusal vertical relation record.
