Non-PRO English to Danish Medical Medical (general)

favour a perforation at the retromolar triangle

This sentence appears in a dental document; the question is regarding: "retromolar triangle"; for the time being, the translation is:"vælg en gennemboring ved det retromolære trekantsniveau"; for information, in Swedish, the translation is: "är det bättre med en perforering i trigone retromale". I would very much appreciate if someone could confirm the Danish translation or send me the corrected version. Thanks in advance.
