Abstract
Purpose:
To investigate two techniques to produce void-free casts from vinyl polysiloxane impressions.
Materials And Methods:
Thirty casts prepared using a conventional technique were compared with 30 casts prepared using a technique involving syringing of stone in terms of numbers of surface voids.
Results:
Significantly fewer surface voids were observed in the casts prepared using syringing technique.
Conclusion:
The syringing technique investigated is considered to have advantages over the conventional technique for the production of casts from vinyl polysiloxane impressions.
