The aim was to evaluate potential relationships between the implant position relative to adjacent teeth and dimensions and topography of the papillae lateral to implant-supported single-tooth restorations.
A total of 32 subjects with a single implant-supported restoration in the esthetic zone of the maxilla were consecutively selected for the study. Soft and hard tissues at the proximal sites of the restoration were evaluated by the use of clinical, photographic, diagnostic cast, and radiographic assessments. A questionnaire was used for assessment of the patients' satisfaction with the esthetic outcome of the restorations. Potential factors influencing the papilla level and the presence of a complete papilla fill were investigated with generalized estimation equations (GEE) analysis.
The bone level at the adjacent tooth significantly influenced the papilla level (P < 0.001). The distance between the contact point and the bone level at the adjacent tooth was significantly shorter for "complete" (4.3 mm) papillae than that for "deficient" papillae (5.7 mm) (P < 0.001). The GEE logistic model revealed that the chance of a complete papilla fill improved with increased facio-lingual thickness of the papilla (P = 0.004) and decreased distance between the contact point and the bone level at the tooth (P = 0.004). The self-reported satisfaction with the esthetic appearance of the implant-born restoration was not significantly different between patients with "complete" and "deficient" papillae.
The probability of a complete papilla fill was significantly affected by the facio-lingual dimension of the papilla base and the distance between the contact point between the crowns and the bone level at the tooth.
评估种植体相对于邻牙的位置与种植体支持的单牙修复体侧方的牙乳头尺寸和形态之间的潜在关系。
本研究连续选择了 32 名上颌美学区单个种植体支持修复的患者。使用临床、摄影、诊断模型和放射学评估来评估修复体近中部位的软组织和硬组织。使用问卷调查评估患者对修复体美学效果的满意度。使用广义估计方程（GEE）分析调查了影响牙乳头水平和牙乳头完整存在的潜在因素。
邻牙的骨水平显著影响牙乳头水平（P<0.001）。与“缺损”牙乳头（5.7mm）相比，“完整”牙乳头（4.3mm）的接触点与邻牙骨水平之间的距离明显更短（P<0.001）。GEE 逻辑模型显示，牙乳头的颊舌向厚度增加（P=0.004）和接触点与邻牙骨水平之间的距离减小（P=0.004），牙乳头完整存在的可能性增加。患者对种植体支持修复体美学外观的自我报告满意度在“完整”和“缺损”牙乳头之间无显著差异。
牙乳头基底部颊舌向尺寸和牙冠与牙之间的接触点与骨水平之间的距离显著影响牙乳头完全存在的概率。
