The aim of the present study is to evaluate the patient satisfaction and marginal adaptation of milled BioHPP polyether ether ketone (PEEK) copings veneered with CAD/CAM composite resin and compare them to milled BioHPP PEEK copings veneered with manual layering.
A total of 32 patients required anterior crowns to restore discolored, fractured, or maligned anterior teeth. Patients were divided into two groups according to the type of restoration used. The Comparator group included patients receiving milled BioHPP PEEK copings veneered with manual layering, while the intervention group was veneered with CAD/CAM composite resin. After final cementation, patient satisfaction and marginal adaptation were evaluated according to the rating score, and modified RYGE criteria respectively, after 6 and 12 months follow-up interval.
Patient satisfaction results at baseline, the mean satisfaction scores were similar between groups, with no significant difference ( = 0.1536). After 6 months, scores increased in both groups, but the difference between groups remained non-significant ( = 0.0660). By 1 year, scores were identical between groups (means both 1.750), and marginal adaptation comparison between both groups (manual veneered) and (CAD/CAM veneered) revealed insignificant differences between both groups at T0, T1, T2.
After 1 year of follow-up, milled BioHPP PEEK copings veneered with manual veneering and CAD/CAM composite resin veneering, showed successful patient satisfaction, and marginal adaptation.
The study may provide guidance for the clinicians to use this veneering technique to match shades that are clinically acceptable when esthetic is required with PEEK crowns good adaptation and easier modification.

本研究旨在评估采用计算机辅助设计/计算机辅助制造（CAD/CAM）复合树脂贴面的铣削生物羟基磷灰石聚醚醚酮（BioHPP-PEEK）冠的患者满意度和边缘适合性，并将其与采用手工分层贴面的铣削BioHPP-PEEK冠进行比较。
共有32例患者需要进行前牙冠修复，以修复变色、折断或排列不齐的前牙。根据所使用的修复类型将患者分为两组。对照组包括接受手工分层贴面的铣削BioHPP-PEEK冠的患者，而干预组采用CAD/CAM复合树脂贴面。在最终粘结后，分别在6个月和12个月的随访间隔后，根据评分和改良的RYGE标准评估患者满意度和边缘适合性。
基线时患者满意度结果显示，两组的平均满意度得分相似，无显著差异（P = 0.1536）。6个月后，两组得分均有所增加，但组间差异仍不显著（P = 0.0660）。到1年时，两组得分相同（均为1.750），两组（手工贴面组）和（CAD/CAM贴面组）之间的边缘适合性比较显示，在T0、T1、T2时两组之间无显著差异。
经过1年的随访，采用手工贴面和CAD/CAM复合树脂贴面的铣削BioHPP-PEEK冠在患者满意度和边缘适合性方面均取得了成功。
该研究可为临床医生提供指导，在需要美学效果时，使用这种贴面技术来匹配临床可接受的颜色，同时PEEK冠具有良好的适合性且易于修改。如何引用本文：Qasem M, El Shehy O, Nabil O. 采用两种不同技术贴面的铣削（PEEK）单颗前牙冠的一年临床评估、患者满意度和适合性。《当代牙科实践杂志》2024；25(8):778 - 789。
