Abstract
OBJECTIVES: To assess the horizontal mucosal thickness (hMT) at healthy and diseased implant sites and correlate these measurements with respective probing depths (PD). MATERIALS AND METHODS: In 60 patients, hMT was assessed at the buccal aspect of healthy (n = 36) and diseased (peri-implant mucositis: n = 26; peri-implantitis: n = 167) implant sites using a validated ultrasonic A-scanner (Pirop® Ultrasonic Biometer A- Scan, Echo-Son, Krancowa, Poland) equipped with a specially designed tissue probe. The corresponding PD values were measured at the mid-buccal aspects. RESULTS: Median hMT (1.10 mm) at healthy implant sites was significantly lower when compared with diseased sites (1.68 mm; 1.61 mm) (P < 0.001, respectively). These values did not markedly differ by implant location (i.e., upper/lower jaws) or position (i.e., anterior/posterior sites). The regression model failed to reveal a significant linear association between hMT and PD values at healthy and diseased implant sites. CONCLUSION: This study has pointed to a significant increase of hMT values at diseased implant sites.
