Impression Tips—Voids

   ISSUE: Voids on the margin of a preparation compromise   
   the fit and function of the final restoration.    


Cause and Solution:


1. Syringe Technique
     • Voids may be reduced by using a stirring motion while syringing, keeping the syringe tip immersed 
        to avoid trapping air.


2. Air incorporated when loading intraoral syringe
     • Front load syringe by inserting mix tip directly into intraoral syringe and forcing the plunger 
       backwards.

   ISSUE: Voids on occlusal surfaces make articulation  

Cause and Solution:

1. Insufficient Tray Support (weak or low tray walls)

     • Use custom or inflexible (preferably metal) stock trays.

2. Teeth in contact with tray and/or not adequately relieving  pre-set impression material

     • Avoid contact of teeth with tray, or pre-set tray material.

3. Insufficient die trimming

     • Consult with dental laboratory.
