Dear. Authors,

This topic will be useful for research of CAD/CAM system and dental materials.

However, there are no new information about denture base resin.

There are several issues that should be addressed in the manuscript before further consideration for publication.

 

Line 62 - 64,

You should mention some references about the first attempt to develop CAD/CAM system or digital equipment.

Line 104-107,

What is the meaning of “depolymerize” ? Does that mean it is “Glass transition temperature” ?

You should add some references or URL of company.

Line 131,

Please add some references.

Line 132,

You should re-consider below.

PMMA is not always better tensile and compressive strength than light curing resin.

Light cured resin has high mechanical properties than that of PMMA depending on measuring method.

Line 182 and others

Please replace residual with unpolymerized.

Line 184, 185 and 207,

ISO number (1567 and others) should be added in this manuscript.

Line 199 and 200,

The bond can be improved by treating the surfaces of “porcelain teeth” with silane “coupling” agents.

Because silane coupling agents does not affect adhesion between PMMA and metal.

Line 207,

Water sorption is already mentioned in this manuscript. There are no information about water solubility. Is there any reason?

Line 233,

P/M ration are mentioned in this line. You should add some references in this line.

Line283, You should add some references about mechanical properties about NextDent® Denture 3D+ .

Line 289,

You mention about Formlabs, USA in this line.

You should add “material, companies, head offices, city or state and Country” in manuscript.

 

Line 357 to 359.

Printing procedure after the scanning is mentioned in this line.

Why any information about processing parameters have not been provided? You should mention that all parameters (“support patterns, layer thickness and layer angle of the prothesis”) are specified.

Line 407,

Replace P value with p value.

Line 388 to Line423,

Results from many research are shown in this sections.

However, there is no discussions about results. I think it is better to add some discussion in this sections.
