Abstract Purpose: Thickness of peri-implant mucosa is an important factor in maintaining an esthetic prognosis. The purpose of this study was to evaluate the morphological features of peri-implant mucosa. Materials and Methods: Forty-two patients, aged 26 to 72 years (average: 48, 20 males and 22 females), who had had Brånemark System® and TiUnite Replacement implants (Nobel Biocare, Göteborg, Sweden) placed in their oral cavity at Tsurumi University Dental Hospital were selected at random. Eighty-two working casts that had been used for fabricating the final prosthesis were examined. The width and height of buccal peri-implant mucosa were measured with a micro-caliper. The measurements were recorded and the means, standard deviations, and frequency were calculated. Correlation analysis was performed to describe the association between the width and the height. Analysis of variance was used to confirm the statistical differences between regions using SPSS12. Results: The width, height and their ratio of peri-implant mucosa measured were (2.45 mm± 0.93, 1.62mm± 0.72, 1.64± 0.73:1) respectively. There was a statistically significant correlation (r=0.48, p=0.00) between the width and the height. In 10 cases, the height of peri-implant mucosa was greater than the width. According to the regions, the widths of the maxillary incisor and canine (p=0.019) and mandibular molar (p=0.000) regions were significantly greater than that of the mandibular premolar region. The heights of the mandibular premolar (p=0.050) and maxillary molar (p=0.040) regions were significantly smaller than that of the maxillary incisor and canine region. The ratio of the maxillary incisor and canine region was significantly less than that of the mandibular molar region(p=0.003). Conclusions: The implant platform was useful as the working reference plane. The height of peri-implant mucosa was significantly less than the width. The ratio of width to height was about 1.64:1.
