Use of separate single-tooth implant restorations to replace two or more consecutive posterior teeth: a prospective cohort study for up to 1 year.

Kwon MJ, Yeo IS, Kim YK, Yi YJ, Yang JH - J Adv Prosthodont (2010)

Bottom Line: 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.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.

ABSTRACT

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.

The means of marginal bone loss were measured at 3, 6, and 12 months after loading. The negative value means marginal bone loss, the positive value and marginal bone gain.

Figure 2: The means of marginal bone loss were measured at 3, 6, and 12 months after loading. The negative value means marginal bone loss, the positive value and marginal bone gain.

Mentions: Fig. 2 shows the mean of the marginal bone loss data acquired from the radiographic evaluation and proportional expression, as mentioned above. The marginal bone around the implants was resorbed after 6 months of loading. However, a small amount of bone was gained after 1 year. The mean marginal bone loss was 0.05 mm at the mesial side of the implant, and 0.12 mm at the distal side after 6 months of loading. The mean marginal bone gain after 1 year was 0.18 mm at the mesial side, and 0.11 mm at the distal side.
