Ni-Cr Alloys Assessment for Dental Implants Suitability

Round 1

Reviewer 1 Report

The paper of Achitei and co-worker entitled ''Ni-Cr alloys assessment for dental implants suitability'' as a whole contains interesting data but needs to be improved after taking into account the comments below.

The article requires major revision.

[1] Authors must provide information regarding medical materials applications such as biocompatibility and cell toxicity.

[2] The mechanical properties you are presenting do not show any std I also think that fracture toughness should be more evaluated as that was the reason this work was made and for that.

[3] Add more XRD experimental details including the previous citations and determined whether the XRD patterns are reflection or transmission mod?

[4] The materials & methods part needs to be improved, all used materials need to be described. Also, cite the work you have followed.

[5] Authors better replace software-generated SEM scale bars with smaller scale bars to show more detail.

Reviewer 2 Report

The manuscript describes a new method to improve a commercial metalic alloy for dental implants. Some experimental details are missing in methodology section. The results are little discussed. 

My suggestions are:

1. Line 140/141: add information such as concentration, temperature, time

2. Figure 2 can be moved to results section together with Table 1. 

3. Add equation to obtain Young modulus and Poisson ratio

4. Line 349/350, the authors claim "The results  showed that the hardness, elastic modulus of the new alloy was significantly increased  compared to classical alloys used" However, the results showed that the modified Verasoft has a lower hardness value. Please verify.
