David joined Linden from a Vienna-based practice focused exclusively on periodontics and implant maintenance. He works hand-in-hand with Dr Văduva on every implant case so the biology is right before the hardware goes in.
He uses laser-assisted therapy for mild to moderate periodontitis and keeps a three-month recall programme for every patient under his care.

Documented cases

A patient with stage 2 periodontitis moved from yearly scales to quarterly airflow maintenance.
What patients say
“Dr Keller fixed three years of gum recession with a tunnel technique. No more sensitivity, and it looks natural.”

“They speak perfect German. I fly in from Munich twice a year for recalls. It's that good.”
