■本系统综述检查了由聚对苯二甲酸乙二醇酯(PeT-G)构成的正畸透明矫正器牙齿矫正器的功效和生物相容性,聚丙烯(PP),聚碳酸酯(PC),热塑性聚氨酯(TPU),和乙烯-醋酸乙烯酯(EVA)。
为了找到到2021年9月发表的相关论文,对PubMed进行了广泛搜索。包括评估对准剂材料的有效性和生物相容性的随机临床试验(RCT)和观察性研究。数据独立提取,并使用相关程序对纳入研究的质量进行了评估。研究的可变性需要叙事综合。
■纳入5项研究进行比较。所有材料都具有生物相容性;然而,PeT-G和EVA对准器引起的组织刺激最小。患者首选TPU矫正器以获得初始舒适度,而首选PeT-G矫正器以获得透明度和耐力。
■生物相容性PET-G,PP,PC,TPU,EVA牙齿矫正器修复咬合不良。应根据患者的喜好选择校准材料,治疗目标,和材料质量。为了更有力的证明,需要进行更长期的研究。
UNASSIGNED: This systematic
review examines the efficacy and biocompatibility of orthodontic clear aligner tooth aligners constructed from polyethylene terephthalate glycol (PeT-G),
polypropylene (PP), polycarbonate (PC), thermoplastic polyurethanes (TPUs), and ethylene-vinyl acetate (EVA).
UNASSIGNED: To find relevant papers published through September 2021, PubMed was searched extensively. Randomized clinical trials (RCTs) and observational studies assessing the effectiveness and biocompatibility of the aligner materials were included. Data were extracted independently, and the quality of included research was appraised using relevant procedures. The research variability necessitated a narrative synthesis.
UNASSIGNED: Five studies were included for comparison. All materials were biocompatible; however, PeT-G and EVA aligners caused the least tissue irritation. Patients preferred TPU aligners for initial comfort and PeT-G aligners for transparency and endurance.
UNASSIGNED: Biocompatible PeT-G, PP, PC, TPU, and EVA tooth aligners fix malocclusions. Aligner materials should be chosen based on patient preferences, treatment goals, and material qualities. For stronger proof, a longer-term study is needed.
