In 5 monkeys a total of 30 transmucosal endosseous dental implants wer
e inserted in edentulous areas of the mandible with presence or absenc
e of keratinized mucosa. After a healing period of 3 months with optim
al plaque control, all implants were exposed to plaque accumulation fo
r periods up to 9 months. To secure abundant plaque accumulation on ha
lf the number of the implants, cotton wool ligatures were placed aroun
d the implants at the entrance to the peri-implant sulcus. Attachment
loss was measured clinically and histometrically, and tissue recession
was measured clinically. Ligated implants without keratinized mucosa
demonstrated significantly more recession and slightly more attachment
loss than the other implants. The results of this study suggest that
the absence of keratinized mucosa around dental endosseous implants in
creases the susceptibility of the peri-implant region to plaque-induce
d tissue destruction.
