Abstract

Aim

To evaluate long-term clinical and radiographic parameters of osseointegrated implants in non-smoker patients with a previous history of chronic periodontitis.

Materials and Methods

Fifty-four screw-type implants with a moderately roughened surface and internal hexagonal implant–abutment connection were placed according to a two-phase protocol and 40 reference teeth were analysed at baseline, and after 5 and 10 years. Pocket probing depth (PPD), clinical attachment level (CAL) and bleeding on probing were analysed 6x/tooth in all teeth, implants and reference teeth. Radiographic peri-implant bone level was measured on the mesial and distal surfaces. The prevalence of peri-implantitis and the survival rate of the implants were assessed at the patient and implant levels. Data were analysed using descriptive statistics, Mann–Whitney U-test, and Wald Z-test, at α = 5%.

Results

In implants, the CAL at 5 years was 0.3 mm higher, and at 10 years 1.2 mm higher in comparison to baseline. The corresponding data for the reference teeth were 0 mm and 0.5 mm respectively. Multilevel testing showed statistical difference for PPD between implants and teeth over time. After 10 years, the mean mesial bone loss was 0.63 ± 0.26 mm, and the mean distal bone loss was 0.56 ± 0.25. The survival rates were 100% and 92.3% for the implants in the mandible and the implants in the maxilla respectively.

Conclusions

Screw-type implants with internal hexagon placed in patients with a previous history of periodontitis attending a regular maintenance programme demonstrated stable clinical and radiographic results after 5 and 10 years.
