Is osseo-densification associated with higher risk of pain and swelling?

Recently had a patient with narrow ridge, and I used Densah drills to expand the ridge. My first use of osseo-densification technique. The surgery to place 15 (FDI) went fine but patient reported pain and swelling one day after surgery, and the pain and swelling (minor) has subsided slightly when I saw her two days after surgery. I placed fixture using cutting drills to replace 24 (FDI) for this patient 3 years ago, and there was no post-surgery pain or swelling. I use cutting drills and pain and swelling is rare, even with ridge splits. Will appreciate response from those who have more experience to make the comparison.
