It makes sense.
When describing directions within the body, including the mouth, anterior & posterior are common references. Here though "distal" makes a little more sense as the direction of the force is most probably related to the distal side of the tooth being moved (occlusal, mesial, distal, buccal and lingual) and not so to the posterior side of the oral cavity (anterior, posterior, medial, lateral, superior and inferior).

You should post your rendering as answer, Reka; it is really good!

I think that might mean "distally". "Primero" is written after it because they are writing the first steps. So the whole translation might look something like "Surgical techniques typically entail the initial repositioning of the tooth occlusally and distally, followed by buccal placement into the desired location to ensure the surrounding periodontal tissues remain healthy."

(...) in an occlusal and posterior direction first... as per philgoddard's WR link.

Could this be plagiarism, or back translation?

The surgical techniques commonly involve moving the tooth occlusally and posteriorly first, followed by buccal positioning of tooth into its desired position to achieve healthy periodontal tissues around the tooth

You posted this elsewhere yesterday - please tell us when you do this, as the question may already have been answered.

Also, you don't need to say 'the tooth' three times as the Spanish does - just say 'it'.
