Abstract

BACKGROUND

It is necessary to investigate the application of polymer materials in implant dentistry. The aim of this study was to examine the outcome of full-arch polyetheretherketone (PEEK)-acrylic resin implant-supported prostheses.

METHODS

Seventy-six patients were rehabilitated consecutively with 100 full-arch implant-supported prostheses of PEEK-acrylic resin (a development group (DG): 37 patients with 5 years of follow-up; a routine group (RG): 39 patients with 1 year of follow-up). The primary outcome measure was prosthetic survival. Secondary outcome measures were implant survival, marginal bone loss, biological complications, prosthetic complications, veneer adhesion, plaque levels, bleeding levels, and a patient subjective evaluation (including the Oral Health Impact Profile for the RG).

RESULTS

In both groups, prosthetic (DG: 93.6%; RG: 100%) and implant survival (DG: 98.9%; RG: 99.5%) were high, and marginal bone loss was low (DG: 0.54 mm; RG: 0.28 mm). The veneer adhesion rate was 28.6% of prostheses in DG (RG = 0%). Mechanical complications occurred in 49% and 11.8% of prostheses in DG and RG, respectively. Biological complications, plaque, and bleeding levels were low in both groups. The subjective patient evaluation was excellent in both groups (8.6 < DG < 8.8; 9.3 < RG < 9.5; OHIP = 1.38).

CONCLUSIONS

Within the limitations of this study, PEEK can be considered a viable prosthetic alternative.

摘要

背景

有必要研究高分子材料在种植义齿中的应用。本研究的目的是检验全牙弓聚醚醚酮（PEEK）-丙烯酸树脂种植体支持式修复体的效果。

方法

连续对76例患者使用100个全牙弓PEEK-丙烯酸树脂种植体支持式修复体进行修复（一个试验组（DG）：37例患者，随访5年；一个常规组（RG）：39例患者，随访1年）。主要观察指标为修复体存留率。次要观察指标为种植体存留率、边缘骨吸收、生物学并发症、修复体并发症、贴面粘结、菌斑水平、出血水平以及患者主观评价（RG组包括口腔健康影响程度量表）。

结果

两组的修复体存留率（DG组：93.6%；RG组：100%）和种植体存留率（DG组：98.9%；RG组：99.5%）均较高，边缘骨吸收较少（DG组：0.54 mm；RG组：0.28 mm）。DG组修复体的贴面粘结率为28.6%（RG组 = 0%）。DG组和RG组修复体的机械并发症发生率分别为49%和11.8%。两组的生物学并发症、菌斑和出血水平均较低。两组患者的主观评价均为优秀（8.6 < DG < 8.8；9.3 < RG < 9.5；OHIP = 1.38）。
