Periodontal conditions of teeth autogenously transplanted by a two-stage technique.

Inflammatory reactions of the marginal periodontal tissues and loss of attachment could partly account for the often occurring rejection of autogenously transplanted mature teeth. The periodontal conditions of transplanted teeth were investigated from 1 month up to 5 years postoperatively. The parameters plaque, bleeding on probing to the bottom of the pocket, probing pocket depth (PPD), gingival recession and probing attachment loss were analysed by multiple regression analysis. No significant difference was found between transplanted and control teeth in bleeding on probing the bottom of the pockets up to 5 years postoperatively with the exception of increased bleeding on probing of the transplanted teeth at the 1-month postsurgery examination. No significant difference of the mean probing depth between transplanted teeth and control teeth was found at the mesio- and distobuccal surfaces. The transplanted teeth at the buccal surface showed increase of the mean pocket depth during the observation period. Increased mean probing depth without progression over time was found at the transplanted teeth compared to the controls at the distolingual, lingual and mesiolingual surfaces. A small mean gingival recession at the transplants was observed. Loss of attachment was recorded at 13% of the surfaces. Totally 50% of the transplants showed loss of attachment and 5% were removed because of extensive attachment loss. On 13% of the transplanted teeth with loss of attachment, root resorption was also found.
