Sleek Dental Training Logo Design

I'm looking for a modern and sleek logo for my company, Implatrain, which offers advanced oral implantology courses for dentists. The logo should clearly convey our identity as an implant training hub.

Key Elements:
- Incorporate a tooth or dental implant
- Include books or learning tools
- Add professional symbols like a graduation cap
- Integrate a train image

Color Scheme: Green and gray

Ideal skills and experience:
- Strong portfolio in modern logo design
- Experience with dental or educational branding
- Proficiency in color theory and application
- Ability to create cohesive and professional imagery

Please provide samples of previous work and a brief concept idea.
