Clinical, Prospective, Non-profit, Non-pharmacological Study on Geass Healing Abutment: Microbiological, Histological, and Immuno-histochemical Evaluation.

"The second surgical stage was done after a healing period 12 ± 4 weeks (T1) where all the healing abutments were placed. Each healing abutment had repeated the two surfaces as twice follows: laser-treated/machined/ laser-treated/machined. Experimental healing abutment was removed after 30 ± 7 days, the same time as the soft tissue biopsy.~After the healing period (30 ± 7 days), before starting with the prosthetic restoration of the fixtures, an impression was taken of the small-diameter Has, and circular sections (diameter 5 mm) soft tissues around them were retrieved for analysis."
