Abstract

Statement of problem

Unscrewing the healing abutment can affect the soft tissue integration and apical migration of the biological width, which may compromise the integrity of peri-implant soft tissue.

Purpose

The purpose of this clinical study was to determine the level of glycosaminoglycan (GAG) detected in the peri-implant crevicular fluid (PICF) between the test group (1-time abutment) and control group (healing abutment) for implant-retained mandibular overdentures.

Material and methods

Two dental implants were installed in the canine regions of the mandibular ridge of 18 healthy completely edentulous participants using 2-stage surgery and a delayed loading protocol. At the second stage surgery, the implant on the right side was exposed, and a healing abutment was screwed onto the implant (control group), while on the left side the definitive ball abutment was screwed onto the implant (test group). After 10 days, the healing abutment in the control group was unscrewed and replaced with the definitive ball abutment. For both groups, the ball attachment was directly picked up to incorporate the attachment house to the mandibular denture. PICF samples were collected from the participants at 7 days, 3 months, and 6 months after overdenture use. Statistical analysis was done with an independent samples t test (α=.05).

Results

A significant difference was found in the volume of PICF and the level of GAG between the test and control groups at the 7-day evaluation period (P=.008, P=.002, respectively), while the volumes of PICF and the levels of GAG were not significantly different (P>.05) at the other evaluation periods.

Conclusions

The 1-time abutment protocol offers biochemical and economic advantages compared with the conventional method of using the healing abutment before placement of the definitive attachment for an implant-retained overdenture with single attachments.

种植体固位下颌覆盖义齿的一次性固位连接与愈合基台植入：种植体周围的代谢活动。

目的本临床研究旨在确定种植体固位下颌覆盖义齿试验组（1次基台）和对照组（愈合基台）种植体周围缝隙液（PICF）中检测到的糖胺聚糖（GAG）水平。材料和方法采用两阶段手术和延迟加载方案，在 18 名完全无牙的健康参与者的下颌嵴犬齿区安装两颗种植体。在第二阶段手术中，暴露右侧的种植体，将愈合基台拧到种植体上（对照组），而在左侧则将确定球基台拧到种植体上（试验组）。10 天后，拧下对照组的愈合基台，换上确定球基台。两组患者都直接取球基台，将基台与下颌义齿连接。分别在覆盖义齿使用 7 天、3 个月和 6 个月后收集参与者的 PICF 样本。统计分析采用独立样本 t 检验（α=.05）。结果在 7 天评估期，试验组和对照组的 PICF 量和 GAG 水平有显著差异（分别为 P=.008 和 P=.002），而在其他评估期，试验组和对照组的 PICF 量和 GAG 水平无显著差异（P>.结论与传统的使用愈合基台再植入最终附着体的方法相比，一次性基台方案具有生化和经济方面的优势。
