Background: Many patients refer to their load implants while there is no attached gingiva in the area of prosthetic implants – unlike the attached gingivae found with natural teeth. The important role played by gingiva in comforting the patient and preventing gingival inflammation has not been fully appreciated yet. This study aimed to evaluate the association between the attached gingival height with gingival inflammation and patients’ comfort.

Methods: This retrospective cohort study was conducted to examine 80 implants (Dio uf) placed in 63 patients. At least two months had passed since the patients had had implant crown. The patients were divided into three groups: attached gingiva, gingival up to 2 mm, and at least 2 mm of attached gingiva. Indices such as bleeding on probing (BOP), the amount of plaque, gingival index and patient comfort during brushing and chewing were evaluated. Statistical data were analyzed using the Kolmogorov– Smirnov test, Levene’s test and independent t-test.

Results: By increasing the height of attached gingiva, decreases were observed in probing depth (P value=0.004), BOP (P value=0.001), the degree of plaque index (P value=0.006), and gingival index (P value=0.003); and this association was statistically quite significant. By increasing the attached gingiva height, furthermore, the patients felt less discomfort when brushing and chewing; however, the findings were not statistically significant in terms of patients’ comfort during chewing (P value=0.364).

Conclusions: Increasing the height of attached gingiva reduced the symptoms of gingival inflammation, but increased patients’ comfort when chewing and brushing.
