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

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.
