Abstract

Objectives: To determine the patient-oriented outcomes after complete denture (CD) treatment using neutral zone (NZ) techniques compared with those of conventional dentures.

Materials and methods: Electronic and hand searches were conducted up to December 2023 based on PICOS criteria. Population (P) was patients with complete edentulism on maxillary and mandibular arches and were either or not wearing CDs. Intervention (I) focused on the fabrication of mandibular and/or maxillary CD using NZ techniques. Comparators (C) included other CD fabrication approaches, such as conventional and simplified techniques, and the use of old or existing CDs. Outcomes (O) were patient-oriented treatment outcomes. Study design (S) included human studies.

Results: Eleven human experimental studies were included. NZ dentures demonstrated better patient-reported outcomes, by providing greater comfort, enhancing denture stability and retention, reducing food traps underneath the denture, as well as improving appearance, chewing efficiency and speech. Objective findings varied, with most studies showing equivalent outcomes for NZ and conventional dentures. However, one study indicated superior, and another demonstrated worse outcomes for NZ dentures.

Conclusions: NZ dentures generally improve patient-reported outcomes more than conventional dentures. However, their impact on objective outcomes compared with a conventional denture remains uncertain.

以患者为导向的全口义齿治疗效果系统回顾:中性区技术与传统方法的比较。
目的与传统义齿相比,确定使用中性区(NZ)技术进行全口义齿(CD)治疗后以患者为导向的疗效:根据 PICOS 标准,在 2023 年 12 月前进行了电子和人工搜索。研究人群(P)为上颌和下颌牙弓完全缺牙且佩戴或未佩戴义齿的患者。干预(I)侧重于使用 NZ 技术制作下颌和/或上颌 CD。比较者(C)包括其他 CD 制作方法,如传统和简化技术,以及使用旧的或现有的 CD。结果(O)是以患者为导向的治疗结果。研究设计(S)包括人体研究:结果:共纳入 11 项人体实验研究。结果:共纳入了 11 项人体实验研究。新西兰义齿通过提供更好的舒适度、增强义齿的稳定性和固位性、减少义齿下方的食物陷阱以及改善外观、咀嚼效率和语言表达能力,显示出更好的患者报告结果。客观研究结果各不相同,大多数研究显示 NZ 假牙和传统假牙的效果相当。然而,一项研究表明新西兰义齿的效果更好,另一项研究则表明新西兰义齿的效果更差:结论:与传统假牙相比,新西兰义齿通常能更有效地改善患者报告的结果。结论:与传统义齿相比,新西兰义齿通常更能改善患者报告的结果,但与传统义齿相比,其对客观结果的影响仍不确定。
