METHODS: Profilometric and pink esthetic score (PES) measurements were performed at the time of implant surgery with GBR (T0) and at the 1- (T1), 2- (T2), and 3-year (T3) follow-up. Patient-reported outcomes were also assessed using the Oral Health Impact Profile-14 (OHIP-14) questionnaire. Statistical analysis over 3 years of follow-up assessed changes at time points (T0, T1, T2, and T3) and time periods (T0-T1, T0-T2, and T0-T3) using the Wilcoxon signed-rank test.
RESULTS: A total of 12 patients (57.5 ± 12.3 years) were included in this study. The mean profilometric change in peri-implant tissues over the 3-year follow-up period was 3.49 ± 1.11 mm, and the buccal contours were not significantly different between the comparison periods. The PES remained stable, while all OHIP-14 domain scores improved significantly.
CONCLUSIONS: Simultaneous implant placement and GBR using the L-shape technique combined with delayed CTG in the maxillary anterior region provides stable buccal profiles and consistent esthetics and improves patient-reported quality of life over a 3-year period.
CONCLUSIONS: This study demonstrated that GBR using the L-shape technique combined with delayed CTG in the maxillary anterior region improved the buccal profile, esthetics, and patient-reported quality of life.
方法:在植入手术时采用GBR(T0)和1-(T1)进行轮廓测量和粉红色美学评分(PES)测量,2-(T2),3年(T3)随访。还使用口腔健康影响概况-14(OHIP-14)问卷评估患者报告的结果。在3年随访期间的统计学分析使用Wilcoxon符号秩检验评估时间点(T0、T1、T2和T3)和时间段(T0-T1、T0-T2和T0-T3)的变化。
结果:本研究共纳入12例患者(57.5±12.3年)。在3年的随访期内,种植体周围组织的平均轮廓变化为3.49±1.11mm,比较期之间的颊轮廓没有显着差异。PES保持稳定,而所有OHIP-14领域评分均有显著改善。
结论:在上颌前区使用L形技术同时植入和GBR结合延迟CTG提供了稳定的颊轮廓和一致的美学,并在3年内改善了患者报告的生活质量。
结论:这项研究表明,使用L形技术的GBR结合上颌前区延迟CTG改善了颊侧轮廓,美学,和患者报告的生活质量。
