To investigate the influence of soft-tissue volume grafting employing autogenous connective tissue graft (CTG) simultaneous to implant placement on peri-implant tissue health and stability.
This cross-sectional observational study enrolled 19 patients (n = 29 implants) having dental implants placed with simultaneous soft-tissue volume grafting using CTG (test), and 36 selected controls (n = 55 implants) matched for age and years in function, who underwent conventional implant therapy (i.e., without soft-tissue volume grafting). Clinical outcomes (i.e., plaque index (PI), bleeding on probing (BOP), probing depth (PD), and mucosal recession (MR)) and frequency of peri-implant diseases were evaluated in both groups after a mean follow-up period of 6.15 ± 4.63 years.
Significant differences between test and control groups at the patient level were noted for median BOP (0.0 vs. 25.0%; p = 0.023) and PD scores (2.33 vs. 2.83 mm; p = 0.001), respectively. The prevalence of peri-implant mucositis and peri-implantitis amounted to 42.1% and 5.3% in the test and to 52.8% and 13.9% in the control group, respectively.
Simultaneous soft-tissue grafting using CTG had a beneficial effect on the maintenance of peri-implant health.
研究自体结缔组织移植物（CTG）同期种植体植入时软组织量移植对种植体周围组织健康和稳定性的影响。
本横断面观察研究纳入了 19 名患者（n = 29 个种植体），他们接受了 CTG 同期软组织量移植的种植体植入（试验组），并选择了 36 名年龄和功能年限相匹配的对照患者（n = 55 个种植体），他们接受了常规种植体治疗（即，无软组织量移植）。在平均 6.15 ± 4.63 年的随访后，评估两组的临床结果（即菌斑指数（PI）、探诊出血（BOP）、探诊深度（PD）和黏膜退缩（MR））和种植体周围疾病的发生率。
在患者水平上，试验组和对照组的中位 BOP（0.0 比 25.0%；p = 0.023）和 PD 评分（2.33 比 2.83 mm；p = 0.001）存在显著差异。试验组的种植体周围黏膜炎和种植体周围炎的患病率分别为 42.1%和 5.3%，对照组分别为 52.8%和 13.9%。
CTG 同期软组织移植对维持种植体周围健康有有益的影响。
