Parodontitis is risicofactor bij implanteren

NTVT, 3 juni 2011


Bij de keuze voor een implantaat in een parodontaal gecompromitteerde mond is de prognose van groot belang. Parodontitis is een potentiƫle risicofactor voor het optreden van peri-implantitis en een vroegtijdig verlies van het implantaat. Kan bij een patiƫnt met parodontitis het plaatsen van een implantaat worden aangeraden?

Abstract
Aim: To compare the 10-year peri-implant bone loss (BL) rate in periodontally compromised (PCP) and periodontally healthy patients (PHP) around 2 different implant systems supporting single-unit crowns.
Materials and methods: In this retrospective, controlled study, the mean BL (mBL) rate around dental implants placed in 4 groups of 20 non-smokers was evaluated after a follow-up of 10 years. Two groups of patients treated for periodontitis (PCP) and 2 groups of PHP were created. For each category (PCP and PHP), 2 different types of implant had been selected. The mBL was calculated by subtracting the radiographic bone levels at the time of crown cementation from the bone levels at the 10-year follow-up.
Results: The mean age, mean full-mouth plaque and full-mouth bleeding scores and implant location were similar between the 4 groups. Implant survival rates ranged between 85% and 95%, without statistically significant differences (P>0.05) between groups. For both implant systems, PCP showed statistically significantly higher mBL rates and number of sites with BL ? 3mm compared with PHP (P<0.0001).
Conclusions: After 10 years, implants in PCP yielded lower survival rates and higher mean marginal BL rates compared with those of implants placed in PHP. These results were independent of the implant system used or the healing modality applied.

Klinische relevantie
Voor een goede prognose van implantaten geplaatst in een parodontaal gecompromitteerde mond is verbetering van de orale zelfzorg van essentieel belang.
