Aim: Additive osseous surgery requires graft material to be placed in osseous defects or for sinus lifting procedure. Placement
of graft material in dummy jaw or on cadaver jaw by students/learners for practice is needed before actual placement on patients.
There is a need to develop a dummy radio-opaque material for use as a practice material by students or learners in defects of dummy
jaw or on cadaver jaw.
Materials and methods: Dummy graft material was prepared from discarded egg-shells (waste) and was used for sinus lifting
in a cadaver goat jaw as taste case.
Result: A measureable radio-opacity of egg-shell particles was seen below the sinus floor after sinus lifting on a cadaver goat
Conclusion: Radio-opaque egg-shell graft material can be used as dummy graft material for practice as a teaching material.
