Abstract

Purpose

To investigate the effect of mid-buccal peri-implant keratinized mucosa width (KMW) ≥2 mm or peri-implant KMW >0 mm and <2 mm on the long-term outcomes of peri-implantitis reconstructive treatment.

Materials and Methods

Twenty-nine patients (40 implants; mean follow-up: 9.2 ± 1.4 years) with at least one implant affected by peri-implantitis and surgically treated through a reconstructive procedure followed by a submerged healing were included. Patients were categorized according to their initial KMW: Group 1 (KMW ≥2 mm) and Group 2 (KMW >0 mm and <2 mm). Peri-implant clinical and radiographic parameters and a dedicated composite outcome were assessed at different follow-up visits during supportive peri-implant therapy for up to 10 years. Regression analyses were utilized to identify possible risk/predictive indicators for probing pocket depth (PPD) change and treatment success at the latest follow-up.

Results

The mean PPD did not exhibit any statistical difference from the baseline to the latest follow-up between the groups at both patient and implant levels. Long-term treatment success was 46.6% (Group 1) and 42.6% (Group 2) at patient level, it was 42.8% (Group 1) and 33.3% (Group 2), respectively, at implant level (p > 0.05). Group 1 demonstrated significantly higher vertical defect depth reduction than Group 2 (p = 0.018). Presence of buccal bony wall and mean PPD at the baseline were found to be associated with mean PPD change, while KMW at 6 months following surgery was identified as the only significant indicator for treatment success (p < 0.05).

Conclusion

Implants with KMW ≥2 mm did not present significantly better long-term clinical outcomes following reconstructive therapy than those exhibiting KMW >0 mm and <2 mm. However, KMW values at the end of healing phase following a submerged approach had a significant impact on long-term treatment success.

种植体周围角化粘膜宽度对种植体周围炎长期重建效果的影响：随访长达 10 年的回顾性分析。

目的：研究中颊面种植体周围角化粘膜宽度（KMW）≥2 毫米或种植体周围角化粘膜宽度>0 毫米对材料和方法的影响：29 例患者（40 个种植体；平均随访时间：9.2 ± 1.4 年）至少有一个种植体受到种植体周围炎的影响，并通过重建手术进行了治疗，随后进行了潜行愈合。根据患者的初始KMW进行分类：第1组（KMW≥2 mm）和第2组（KMW>0 mm）：从基线到最近一次随访，两组患者和种植体的平均 PPD 均无统计学差异。患者层面的长期治疗成功率分别为 46.6%（第一组）和 42.6%（第二组），种植体层面的长期治疗成功率分别为 42.8%（第一组）和 33.3%（第二组）（P > 0.05）。第一组的垂直缺损深度明显高于第二组（p = 0.018）。发现颊骨壁的存在和基线时的平均 PPD 与平均 PPD 的变化有关，而术后 6 个月时的 KMW 被认为是治疗成功的唯一重要指标（p 结论：KMW ≥ 0.05 的种植体比 KMW ≥ 0.05 的种植体更容易获得成功，而 KMW ≥ 0.05 的种植体比 KMW ≥ 0.05 的种植体更容易获得成功：KMW≥2毫米的种植体与KMW>0毫米和KMW≥2毫米的种植体相比，在重建治疗后的长期临床效果并没有明显的改善。

期刊介绍： The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
