    18 Years of Speaking Out on the Issues that Affect the Implant Industry:
    " Since 1982, I have been speaking out on the many controversies and issues that affect implant dentistry. Editorials, open letters to the profession and e-mail exchanges in response to my participation in an online implant discussion group have been the forums for these discussions. Regardless of the system you are using or your degree of involvement in implant dentistry, I believe you will find these discussions informative and entertaining.
