Does a dental implant and crown need to have the same manufacturer when installed at the dentists office?

My dental implant surgeon uses a Strau--n and a Bio--i implant system. My restorative general dentist (at a different location) said that I should get a Strau--n implant but did not say why. And, I will not push him to ask about it. Does a Strau--n implant require a Strau--n crown or not? Thank you in advance.
