[Effect of orthodontic tooth intrusion on the periodontium. Clinical study of changes in attachment level and probing depth at intruded incisors ].
The goal of the present study was to measure attachmentlevel changes in patients of 12-48 years of age whose maxillary incisors have been intruded during an orthodontic treatment lasting between 9 and 14 months. Clinical parameters such as clinical probing depth, clinical attachment level and bleeding on probing were evaluated. The results show that i) the intruded teeth gained an average of 0.6 mm of clinical attachment, while the control teeth showed a stable attachment level and ii) the clinical probing depth remained stable at test and control teeth. It was concluded that orthodontical intrusion of maxillary front teeth in patients with a high level of oral hygiene maintains stable periodontal parameters and may even lead to a small clinical attachment gain.
