- PURPOSE. The aim of this study was to evaluate the periodontal and prosthodontic complications of multiple freestanding implants in the posterior
jaws for up to 1 year of function. MATERIALS AND METHODS. Eight patients received 20 implants posterior to canines. Two or more
implants were consecutively inserted to each patient. Single crowns were delivered onto the implants. Marginal bone loss, implant mobility, probing
depth, and screw loosening were examined to evaluate the clinical success of such restorations for maximum 1 year of functional loading.
RESULTS. All the implants performed well during the observation period. Neither periodontal nor prosthodontic complications were found except
a slight porcelain chipping. While the marginal bone level was on average 0.09 mm lower around the implant after 6 months of loading, it was
0.15 mm higher after 1 year. CONCLUSION. Within the limits of this investigation, separate single-tooth implant restorations to replace consecutive
missing teeth may clinically function well in the posterior jaw.
