Osstem Implant leads efforts to establish international implant standards: Consensus paper by eight global clinical experts published in an international journal
– Fourteen clinical guideline statements proposed covering prosthetic design, abutment materials and implant placement depth
– Evidence-based recommendations from a scoping review of the literature
Paper titled “Factors Affecting the Implant Supracrestal Complex: A Consensus Paper from the Global Consensus Meeting Organized by the Osstem Implant Community.”
Osstem Implant has published a consensus paper in an international scientific journal after bringing together eight globally recognised clinicians to establish international implant standards. The initiative reflects the company’s intention to contribute to the advancement of implant dentistry worldwide by proposing standardised clinical guidelines based on validated clinical data from both domestic and international sources.
The consensus was developed through the Osstem Implant Global Consensus Meeting, a scientific initiative that brings together internationally recognised experts—including directors of the Osstem Master Course programme—to discuss and establish clinical guidelines at a global level. Organised by Osstem Implant, the meeting has been held regularly since 2023 in both online and offline formats with participation from experts from around the world.
The newly published consensus represents the second guideline, following the previously released Osstem Global Consensus Report titled “Prosthetic Guidelines to Prevent Implant Fracture and Peri-Implantitis: A Consensus Statement from the Osstem Implant Community.”
The latest meeting focused on factors affecting the implant supracrestal complex. Eight experts participated in the discussion, including three clinicians from South Korea—Dr Lee Soo-young, Dr Cho Young-jin and Prof. Noh Kwan-tae—and five international experts: Prof. Marco Tallarico (Italy, chair), Prof. Chikahiro Ohkubo (Japan), Prof. Gaetano Noè (Italy), Dr Felipe Aguirre (Chile) and Dr Recep Uzgur (Türkiye).
During the meeting, the panel discussed a range of topics related to the implant supracrestal complex, including the definition and clinical significance of the supracrestal complex, prosthetic design elements such as emergence profile and emergence angle, selection of abutment materials, and implant placement depth and positioning.
In preparation for the discussion, an extensive scoping review of the literature was conducted to examine the question: “Which prosthetic factors influence the implant supracrestal complex?” The selected studies were evaluated for quality using the Newcastle–Ottawa Scale (NOS).
As a result of the meeting, 14 consensus statements were developed and presented as practical clinical guidelines. The recommendations address topics including the definition of peri-implant tissue attachment (PTA), the advantages of screw-retained prostheses, clinical application of platform switching, optimisation of abutment design—including concave profiles and emergence angles—guidelines for implant placement depth and positioning, recommendations for abutment material selection, the “one abutment–one time” protocol, and the application of digital technologies and AI-assisted approaches.
The recommendations aim to provide practical guidance for clinicians to optimise long-term implant outcomes.

The consensus paper was published in Prosthesis, an MDPI journal, under the title “Factors Affecting the Implant Supracrestal Complex: A Consensus Paper from the Global Consensus Meeting Organized by the Osstem Implant Community.” The paper was authored by Prof. Marco Tallarico of Italy, who chaired the meeting.

Dr Cho In-ho, director of the Osstem Dental Research Institute, commented:
“Prosthetic design and abutment material selection are critical factors influencing peri-implant tissue stability and aesthetic outcomes in implant dentistry. This consensus was developed to provide clear, evidence-based clinical guidelines for the design, selection and clinical use of implant abutments and prosthetic components to optimise the biological, mechanical and aesthetic performance of the implant supracrestal complex.”
He added:
“Osstem Implant will continue to organise consensus meetings and support clinical research activities to propose practical guidelines that contribute to the advancement of implant dentistry worldwide.”
