摘要
PURPOSE: This cross-sectional study was performed to determine whether an
association exists between the width of keratinized mucosa and the health of
implant-supporting tissues. MATERIALS AND METHODS: Data on 200 dental implants
were collected. Periodontal parameters measured included Plaque Index, Gingival
Index, width of keratinized mucosa, thickness of keratinized mucosa, radiographic
bone level, and bleeding on probing. Statistical analysis was accomplished with
the t test, Wilcoxon rank sum test, and logistic and linear regression models.
Significance was established when P was less than .05. RESULTS: The mean Gingival
Index score, Plaque Index score, and radiographic bone loss were significantly
higher for those implants with a narrow zone (< 2 mm) of keratinized mucosa.
Implants with a narrow zone of keratinized mucosa also were more likely to bleed
upon probing, even after adjusting for Plaque Index, smoking, thickness of the
gingiva, and time since implant placement (adjusted odds ratio, 2.37; 95%
confidence interval, 1.04 to 5.83). Significant independent association also was
found between the width of keratinized mucosa and radiographic bone loss in favor
of wider zone of keratinized mucosa. CONCLUSION: Increased width of keratinized
mucosa around implants is associated with lower mean alveolar bone loss and
improved indices of soft tissue health.
