The aim this study was to evaluate the factors that influence the presence or absence of the interproximal papilla between implants adjacent to the teeth or other implants, through clinical and radiographic evaluation.
The non-probabilistic sample comprised 44 patients of both genders aged between 21 and 68 years, rehabilitated with 114 osseointegrated implants. Through a retrospective clinical study, the patients were divided according to the presence or absence of the interproximal papilla: Group 1 - Absence of Papilla, Group 2 - Partial Presence of Papilla and Group 3 - Total Presence of Papilla. The success of the implants, the periodontal biotype, and the vertical and horizontal distances of the interproximal regions included in the study were evaluated.
Of the 114 implants, 46.5% were considered unsuccessful, and bleeding was present in 29.8%. The periodontal biotype presented as thin and scalloped was found in 85.1% of the regions. The evaluation of the groups according to the confirmation of the interproximal space showed a statistically significant difference (p = 0.007), with 61.9% of the wide and long interproximal spaces classified as Group 1, while 31% of the narrow and short interproximal spaces were classified as Group 3.
It was concluded that the morphology of the interproximal space was the factor that was most strongly associated with the presence or absence of the interproximal papilla.
本研究旨在通过临床和影像学评估，探讨影响相邻牙齿或其他种植体之间种植体近中乳头存在与否的因素。
非概率样本包括44名年龄在21至68岁之间的男女患者，共植入114颗骨结合种植体。通过回顾性临床研究，根据近中乳头的存在与否将患者分为：第1组 - 无乳头组，第2组 - 部分有乳头组，第3组 - 完全有乳头组。评估种植体的成功率、牙周生物型以及研究中包括的近中区域的垂直和水平距离。
在114颗种植体中，46.5%被认为不成功，29.8%存在出血情况。85.1%的区域呈现为薄且呈扇贝状的牙周生物型。根据近中间隙的确认对各组进行评估，结果显示存在统计学显著差异（p = 0.007），61.9%的宽且长的近中间隙被归类为第1组，而31%的窄且短的近中间隙被归类为第3组。
得出的结论是，近中间隙的形态是与近中乳头的存在与否最密切相关的因素。
