(Concern) Choosing an implant

My teeth have been bad since I was young.

It seems that the tooth is weaker than others.

I fell and lost my front tooth, so I got a new one implanted ㅠㅠ

I need to get a molar implant.

They told me to choose between Osstem and Dentiium at the dental clinic.

Osstem Implant is more expensive than Dentium.

Which one do you prefer?
