Focal areas of gingival hyperplasia surrounding the transmucosal portions of titanium implants have been attributed to poor hygiene, lack of attached gingival tissues, and titanium allergy. Following mandibular vestibuloplasty and placement of a split-thickness skin graft, two of five patients developed persistent proliferation of the epithelial tissue surrounding endosseous CP titanium dental implants. In both circumstances, traditional gingivectomy procedures, chemotherapeutic agents, and aggressive oral hygiene measures failed to adequately control the hyperplastic response. Following replacement of the titanium abutments with custom-fabricated gold abutments, the epithelial condition appeared to return to normal.
钛种植体经黏膜部分周围牙龈增生的局部区域被认为与口腔卫生不良、附着龈组织缺乏以及钛过敏有关。在下颌前庭成形术及放置中厚皮片后，五名患者中有两名出现了骨内CP钛牙种植体周围上皮组织的持续增生。在这两种情况下，传统的牙龈切除术、化疗药物以及积极的口腔卫生措施均未能充分控制增生反应。在用定制的金基台替换钛基台后，上皮状况似乎恢复了正常。
