Abstract

Objectives

To assess the impact of a two-piece abutment workflow on enhancing the stability of the alveolar bone and gingiva surrounding the dental implant, and to determine the level of patient satisfaction.

Materials and Methods

A total of 48 patients with dentition defect in the posterior region were included and divided into two groups: the two-piece abutment workflow (TAW) and the sealing screw with submerged healing workflow (SHW). Marginal bone level (MBL), soft tissue indicators, oral hygiene indicators, and patient satisfaction were assessed and recorded partially at 0, 3, 6, and 12 months after surgery. The primary outcome was the change of MBL in different time periods. A generalized linear mixed model (GLMM) was used to take into account the correlated nature of the data, and adjust for potential confounding factors within inter-group differences.

Results

The survival rate of implants and prosthesis reached 100% at 12-month follow-up, with an average decrease of 0.25 mm (SD 0.23 mm) of MBL in the TAW group and 0.48 mm (SD 0.45 mm) in the SHW group. The change of MBL in the TAW group (0.15 ± 0.31 mm) was significantly lower than the SHW group (0.41 ± 0.41 mm) through the analysis of GLMM within 6 months, while no significance was found in 12 months. Moreover, less gingival pain and oppression during prosthesis loading, and less time consumption overall duration were showed in the TAW group through Visual Analogue Scale (VAS, p < 0.05).

Conclusions

Within a 6-month period, the two-piece abutment workflow showed superior efficacy in preserving the integrity of the marginal bone level. Furthermore, it streamlined treatment procedures and mitigated discomfort, hence increasing patient satisfaction.

符合后牙区一次一基台概念的两件式基台的临床疗效：临床试验研究。

目的评估两件式基台工作流程对提高种植牙周围牙槽骨和牙龈稳定性的影响，并确定患者的满意度：共纳入48名后部牙列缺损患者，并将其分为两组：两件式基台工作流程（TAW）和浸没式愈合密封螺钉工作流程（SHW）。在术后 0、3、6 和 12 个月对边缘骨水平 (MBL)、软组织指标、口腔卫生指标和患者满意度进行部分评估和记录。主要结果是不同时间段内边缘骨水平的变化。使用广义线性混合模型（GLMM）来考虑数据的相关性，并调整组间差异中的潜在混杂因素：结果：随访 12 个月时，种植体和假体的存活率达到 100%，TAW 组 MBL 平均下降 0.25 毫米（标度 0.23 毫米），SHW 组 MBL 平均下降 0.48 毫米（标度 0.45 毫米）。通过 GLMM 分析，在 6 个月内，TAW 组 MBL 的变化（0.15 ± 0.31 mm）明显低于 SHW 组（0.41 ± 0.41 mm），而在 12 个月内则无显著性差异。此外，通过视觉模拟量表（VAS，P）显示，TAW 组在装载假牙时牙龈疼痛和压迫感较轻，整个持续时间耗时较短：在 6 个月的时间内，两件式基台工作流程在保持边缘骨水平的完整性方面表现出了卓越的功效。此外，它还简化了治疗程序，减轻了不适感，从而提高了患者的满意度。

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.
