Checking crown prep clearance with a putty index
OslerPress guide · 4 min read
Take the putty over the unprepared tooth and its neighbors, let it set, and cut it through the buccal-lingual midline.
Figure 1. The gap between the index and the prep is the clearance.
Read the clearance
Set the index back after the prep and photograph the section. OslerPress reads the gap against the occlusal band, 1.0–2.0 mm.
Clearance inside 1.0–2.0 mm all along the section scores as within.
