Implant Dentistry Without Peri-Implantitis is a Reality

About the Patent™ Dental Implant System

Thanks to Patent™ Dental Implants, an ever-growing number of clinicians worldwide experience on a day-to-day basis that implant dentistry without peri-implantitis is a reality–today.

In 2003, two distinguished implant specialists from Germany began developing a novel dental implant with the aim of addressing the surging numbers of peri-implantitis cases occurring with the existing systems, despite decades of clinical experience. 

Keys to Success: Soft-Tissue Seal, No Microgap at Bone Level

Recognizing that peri-implantitis always originates in the soft tissue and is caused by pathogenic bacteria, their goal was to foster soft-tissue adhesion to the implant surface so strong that it could prevent bacteria from invading the peri-implant tissue.

They achieved this goal through an unprecedented combination of a specialized surface topography, a unique soft-tissue level design and a novel material composition, allowing a soft-tissue seal to form around the implant’s transgingival portion—providing an ideal defense barrier against bacteria. Equally crucial to this ability to minimize the risk of chronic tissue inflammation like peri-implantitis, the implant design avoids a microgap at the critical crestal bone level, where bacteria could potentially accumulate.

In histological analyses, Glauser and Schüpbach demonstrated that the mucophilic surface of the Patent™ Implant establishes strong and intimate contact with the soft tissue.

Long-term Studies: No Peri-Implantitis After 9 and 12 Years

In 2019, this innovative dental implant technology was acquired by Zurich-based manufacturing company Zircon Medical Management AG and continued its unparalleled success story under the brand name Patent™. Today, the Patent™ Dental Implant System has a performance record of over 20 years of clinical use by long-standing users, and its long-term success has been validated by independent long-term studies at the universities of Düsseldorf and Graz, which found healthy soft tissue and only minimal marginal bone loss after 9 years of function and no peri-implantitis even after 12 years.[1, 2]
