For the last 15 years, I have been using Geistlich Bio-Oss® and Geistlich Bio-Gide® for various bone augmentation and preservation procedures, with consistently excellent outcomes. Recently, I have also discovered the great properties and various applications of Geistlich Mucograft® in oral implantology. The vast amount of clinical research utilising these products have provided me with additional confirmation in the reliability of Geistlich. For these reasons, I am not ready to switch to other products any time soon. Vinh Nguyen, DDS, MSc.
