The relationship between periodontitis and peri‐implantitis remains a matter of debate. The present study compared, “within” randomly chosen partially edentulous patients ( n =84 subjects, 97 jaws), the marginal bone loss around teeth and implants during 5 years (range 3 to 11 years) following the first year of bone remodelling. The patients had all been rehabilitated by means of screw‐shape c.p. titanium implants with a machined surface (Brånemark system ® ). During the 5 years observation interval, periodontal parameters (marginal bone and attachment loss, the latter for teeth only) were collected together with data on confounding factors (smoking, oral hygiene, tooth loss). Marginal bone loss was measured through long‐cone intra‐oral radiographs. The mean “interval” bone loss was significantly ( P =0.0001) higher around teeth (0.48±0.95 mm) than around implants (0.09±0.28 mm). The corresponding data for the “worst” performing tooth (0.99±1.25 mm) and implant (0.19±0.32 mm) per subject showed the same tendency. Neither attachment nor bone loss around teeth correlated with marginal bone loss around implants. This study indicated that the rate of bone loss around screw‐shape c.p. titanium implants with a machined surface (Brånemark system ® implants) was not influenced by the progression rate of periodontal destruction around the remaining teeth within the same jaw.
