Dental Implants - Parallel x Conical

1. Depends on brand you use to perform surgery, each brand haves its tools, the surgery kit of intruments from i3, doesnt work on Miss, or other brands for example.
2. Parallel or Conical: Conical its similar physiologycally to a dental root, so it could be better, but theres some reasons for not goingo on conical on upper jaw (maxilla)
3. Conical Are The latest Technology but you can use it for everything.
4. ?¿?¿?¿?¿?
5. The best brank to this date its i3, Branemark brand, are from Sweden and its engineered by the doctor that discovered the dental implants, Dr. Branemark.
6. Titanium Grades are a fake and cheating information that gives dentists in USA, When you buy implants to your dental depot, or dental provider, they dont sell implants by titanium grade. all are titanium grade 5. Dentist in USA use to give that information to look like they are so technologically specialists or something like that, or they are giving you titanium implants because theres grades 1 and 2 and 3......, actually the only implants are made in grade 5.

Why do some men like red sports cars and some like black? Personal preference, as far as I know.

What are the advanatages of red sports cars versus black sports cars? Black shows dirt less easily. But then it also gets hotter inside too, and it nets out no advantage.

What is considered more "moderen"- red or black sports cars? Depends on where you live, I guess.

Besides red and black, what other colors of sports cars are available? All sorts of different colors- more than you will ever need.
