To assess the long-term clinical outcomes following non-surgical therapy of peri-implant diseases at two-piece zirconium implants.
A total of 27 patients suffering from either (i) peri-implant mucositis (n = 24 implants), or (ii) peri-implantitis (n = 16 implants) completed a mean follow-up period of 32.8 ± 2.85 months (median: 34 months). The initial treatment procedures included (i) mechanical debridement + local antiseptic therapy using chlorhexidine digluconate (MD + CXH), or (ii) Er:YAG laser monotherapy (ERL). The primary outcome was disease resolution (i.e. absence of bleeding on probing (BOP) at mucositis sites/absence of BOP and probing pocket depths (PD) ≥6 mm at peri-implantitis sites).
Resolution of peri-implant mucositis and peri-implantitis was obtained in 7/14 (50.0%; p = .003) and 5/13 (38.5%; p = .001) of the patients investigated. This corresponded to 54.2% (13/24) and 50.0% (8/16) at the implant level respectively.
Both MD + CHX and ERL were effective on the long-term, but failed to achieve a complete disease resolution.
评估两段式氧化锆种植体非手术治疗种植体周围疾病的长期临床疗效。
共有 27 名患者（24 个种植体患有种植体周围黏膜炎，16 个种植体患有种植体周围炎）接受了平均 32.8 ± 2.85 个月（中位数：34 个月）的随访。初始治疗方案包括（i）机械清创+局部使用葡萄糖酸氯己定抗菌治疗（MD+CXH），或（ii）Er:YAG 激光单疗法（ERL）。主要结局为疾病缓解（即黏膜炎部位无探诊出血（BOP）/种植体周围炎部位无 BOP 且探诊深度（PD）≥6mm）。
14 名患者中有 7 名（50.0%；p=0.003）和 13 名患者中的 5 名（38.5%；p=0.001）缓解了种植体周围黏膜炎和种植体周围炎。这分别对应于 24 个种植体中的 54.2%（13/24）和 16 个种植体中的 50.0%（8/16）。
MD+CHX 和 ERL 在长期治疗中均有效，但未能实现完全的疾病缓解。
