Description

The term Hybrid Design (HD) was first used by Dennis Tarnow in 1993. The term standsfor an implant with a micro-rough implant surface in the endosseous portion to promotefaster and better osseointegration of the implant during healing and during function and asmooth, machined surface in the neck/collar region for the transcrestal area with contact tothe peri-implant sulcus. The most prominent HD implant is the tissue level implant, whichwas first inserted in patients in 1986 at the University of Bern (Buser et al. 1988). Clinicallong-term studies with Tissue level implants have clearly documented the least risk for thedevelopment of peri-implant mucositis and peri-implantitis (Derks et al. 2016a; Derks et al.2016b) when compared with implants with a micro-rough surface, all the way up to theimplant neck. The long-term documentation at the University of Bern confirmed the lowrisk of roughly 3% for developing peri-implantitis with Tissue level implants in a large 10-yearstudy with 500+ Tissue level implants (Buser et al. 2012). A most recent study by Windael etal. (2021) with 1478 non-HD implants and a 10-year observation period confirmed this again. Implants with an early bone loss (EBL) ≥0.5 mm during the first year of function showed a 5xtimes higher odds ratio for future peri-implantitis development. EBL of >0.5 mm means an exposure of the micro-rough surface to the peri-implant sulcus. This lecture will present all relevant aspects of HD implants and what surgical factors are essential to achieve successfuloutcomes with good long-term stability.
