基台或种植体表面上的牙菌斑积聚会引起牙龈/牙槽粘膜中的炎症反应，就像牙齿周围一样。种植体周围炎和/或咬合过载可能会危及口腔种植体的寿命。在部分无牙患者中，牙齿周围的囊袋充当种植体周围囊袋定植的储存库，种植体周围软组织的炎症反应风险似乎比完全无牙患者更合理。对于具有非常粗糙表面的植入物（例如，等离子喷涂），因为表面粗糙度与龈上和龈下菌斑形成之间存在正相关关系。几项中期（5 - 10年）临床研究通过观察到持续的骨丢失和随后的成功/生存率下降支持这一假设。咬合超负荷增加了两阶段种植体-骨界面微骨折的风险，这可能导致显著的边缘骨丢失甚至失败。有充分的证据表明，咬合因素与两阶段种植体周围的边缘角缺陷有关。
Plaque accumulation on abutments or implant surfaces induces an inflammatory reaction in the gingiva/alveolar mucosa just as around teeth. The longevity of oral implants can be jeopardized by either peri-implantitis and/or an occlusal overload. In the partially edentulous patient in whom pockets around teeth act as a reservoir for the colonization of the pockets around implants, the risk for inflammatory reactions of the peri-implant soft tissues seems especially more plausible than in the fully edentulous patient. This is especially true for implants with a very rough surface (e.g., plasma-sprayed), because of the positive relationship between surface roughness and supra- as well as subgingival plaque formation. Several medium-term (from 5 to 10 years) clinical studies support this hypothesis, through the observation of ongoing bone loss and subsequent decreasing success/survival percentages. Occlusal overload increases the risk for microfractures at the implant-bone interface in two-stage implants, which can result in significant marginal bone loss and even failure. There is ample evidence that occlusal factors are related to marginal angular defects around two-stage implants.
