Abstract

BACKGROUND

To minimize misfit between prosthesis and implant, the welding of the implant fixed partial denture (IFPD) framework is recommended and autopolymerized acrylic resin (AR) is the material of choice for the indexing process. As for any prosthetic device that comes into contact with saliva and blood in the oral cavity, IFPD indexed with AR must be disinfected before sending to the laboratory. However, disinfection procedures are often neglected for fear of shrinkage or distortion caused by a dimensional change of the acrylic resin. Peracetic acid is a high-level disinfectant agent at low concentrations and immersion time, with no reported toxic residues, and it is not inactivated in the presence of organic matter when compared to other disinfectants. This study aimed to evaluate the influence of 0.2% peracetic acid disinfectant solution after different storage media and times on the horizontal dimension of IFPD frameworks indexed with AR.

MATERIAL AND METHODS

IFPD frameworks were indexed with two AR: group 1 Duralay and group 2 Pattern Resin LS. Each group was further divided into five subgroups according to disinfection procedure and storage medium: no disinfection and dry storage, no disinfection and water storage, 0.2% peracetic acid disinfection and water storage, 0.2% peracetic acid disinfection and peracetic acid storage, and 0.2% peracetic acid disinfection and dry storage. The horizontal dimension of the specimens and an average was established for analysis. Measurements were performed at four different storage times (hours): T0, T24, T48, T168.

RESULTS

No statistical differences were found when T0 was compared to T168 for Pattern resin groups submitted to disinfection and storage in water (group 2b, p = 1.000) or peracetic acid solution (group 2c, p = 0.352). For Duralay groups, the use of peracetic acid solution did not affect the horizontal dimension of the specimens when T0 was compared to T168 only with water as a storage medium (group 1b, p = 1.000). Additionally, T0 did not differ from T24 for groups 1c (p = 0.553), 2b (p = 1.000), 2d (p = 0.234), and 2e (p = 1.000) and from T48 for groups 1d (p = 0.118) and 2b (p = 1.000).

CONCLUSION

Within the studied conditions, the use of 0.2% peracetic acid can be safely used as a disinfectant solution regarding dimensional stability of AR-indexed IFPD until 7 days of storage. Horizontal discrepancies are dependent on acrylic resin type, time, and medium of storage.

摘要

背景

为使修复体与种植体之间的不匹配最小化，建议对种植固定局部义齿（IFPD）支架进行焊接，且自凝丙烯酸树脂（AR）是用于转移印模过程的首选材料。对于任何在口腔中与唾液和血液接触的修复装置，用AR转移印模的IFPD在送往实验室之前必须进行消毒。然而，由于担心丙烯酸树脂尺寸变化导致收缩或变形，消毒程序常常被忽视。过氧乙酸是一种低浓度和短浸泡时间的高效消毒剂，未报告有毒残留，与其他消毒剂相比，在有有机物存在时不会失活。本研究旨在评估0.2%过氧乙酸消毒溶液在不同储存介质和时间后对用AR转移印模的IFPD支架水平尺寸的影响。

材料与方法

IFPD支架用两种AR进行转移印模：第1组为Duralay，第2组为Pattern Resin LS。根据消毒程序和储存介质，每组进一步分为五个亚组：不消毒并干燥储存、不消毒并水储存、0.2%过氧乙酸消毒并水储存、0.2%过氧乙酸消毒并过氧乙酸储存、0.2%过氧乙酸消毒并干燥储存。确定标本的水平尺寸并进行平均以进行分析。在四个不同的储存时间（小时）进行测量：T0、T24、T48、T168。

结果

对于在水中消毒和储存的Pattern树脂组（第2组b，p = 1.000）或过氧乙酸溶液中消毒和储存的组（第2组c，p = 0.352），当将T0与T168比较时，未发现统计学差异。对于Duralay组，仅以水作为储存介质时，当将T0与T168比较时，过氧乙酸溶液的使用不影响标本的水平尺寸（第1组b，p = 1.000）。此外，第1组c（p = 0.553）、第2组b（p = 1.000）、第2组d（p = 0.234）和第2组e（p = 1.000）的T0与T24无差异，第1组d（p = 0.118）和第2组b（p = 1.000）的T0与T48无差异。
