Abstract

Background

The effect of keratinized mucosa on peri-implant tissue health is still inconclusive. This study aimed to evaluate the importance of keratinized mucosa and investigate the impact of the free gingival graft procedure on peri-implant health.

Methods

At prosthesis delivery, the implants were allocated into three groups, based on the width of keratinized mucosa (KM) and patients' agreement on the free gingival graft procedure: KMS (KM ≥2 mm), KMD (KM <2 mm), and FGG (KM <2 mm initially and having surgically increased keratinized mucosa). Modified plaque index (mPI), probing depth (PD), modified bleeding index (mBI), KM, and marginal bone loss (MBL) were assessed at the baseline, 6-, 12-, and 24-month follow-up periods.

Results

Of the 47 patients, 17 belonged to the KMS group, 17 belonged to the KMD, and the remaining 13 patients belonged to the FGG. KMD demonstrated significantly fewer mPI and higher mBI than KMS and FGG at 6 and 12 months. At 24 months, MBL did not differ between the groups; however, PD was significantly greater in the KMD group.

Conclusions

Implants with inadequate keratinized mucosa had higher bleeding and pocket depth values despite less plaque accumulation. According to the results, soft tissue grafting should be performed as early as possible. © 2023 Australian Dental Association.

评价角化粘膜对种植体周围组织健康的意义:一项前瞻性临床试验

背景角化黏膜对种植体周围组织健康的影响尚不明确。本研究旨在评估角化黏膜的重要性，并探讨游离牙龈移植手术对种植周健康的影响。方法在种植体交付时，根据角膜角质化粘膜宽度(KM)和患者对游离牙龈移植方式的同意程度将种植体分为三组:KMS组(KM≥2mm)、KMD组(KM + lt; 2mm)和FGG组(KM + lt; 2mm，初始角膜角质化粘膜已手术增加)。在基线、6个月、12个月和24个月的随访期间评估改良斑块指数(mPI)、探查深度(PD)、改良出血指数(mBI)、KM和边际骨质流失(MBL)。结果47例患者中，KMS组17例，KMD组17例，FGG组13例。在6个月和12个月时，KMD的mPI明显低于KMS和FGG, mBI明显高于KMS和FGG。在24个月时，两组间MBL没有差异;然而，PD在KMD组明显更大。结论角化黏膜不充分的种植体出血和种植袋深度值较高，但斑块积累较少。根据结果，应尽早进行软组织移植。©2023澳大利亚牙科协会。
