Abstract

This prospective study involved 35 edentulous adults aged 50 years and older, treated at a dental clinic. Data were collected across four time points: baseline (T0), 3 months post-application of conventional complete dentures (CD; T1), and 3 and 6 months after the transition to implant-supported overdentures (IOD; T2 and T3). Patient outcomes were assessed using: Mini Nutritional Assessment (MNA): To evaluate nutritional status, Oral Health Impact Profile (OHIP-14): To measure oral health-related quality of life (OHRQoL) and Chewing Ability Questionnaire: To document functional improvements. Mini Nutritional Assessment (MNA) scores declined initially after transitioning to CDs (T0–T1) but stabilized following implant overdenture placement. Significant improvements were reported, with chewing difficulty decreasing from 91.4% at baseline to 51.4% at T3. Marked enhancements in OHIP-14 scores at T2 and T3, indicating better oral health perception. While implant overdentures significantly improved chewing ability and quality of life, they did not lead to measurable improvements in nutritional status. The findings highlight the functional and psychosocial benefits of implant overdentures for older adults, suggesting that oral rehabilitation enhances overall well-being even without direct nutritional effects. This study provides a moderate level of evidence based on its prospective design, validated outcome measures, and clear findings related to chewing ability and oral health-related quality of life. However, the small sample size, lack of long-term follow-up, and absence of significant improvements in nutritional status suggest the need for further research to validate and strengthen these findings. Future studies with larger populations and extended observation perimplant overdentures are essential to enhance the robustness and generalizability of the evidence.
种植覆盖假牙是否能改善咀嚼能力和生活质量,尽管对营养状况没有影响?
资料来源:这项前瞻性研究涉及35名年龄在50岁及以上的无牙成年人,在牙科诊所接受治疗。数据收集于四个时间点:基线(T0),常规全口义齿应用后3个月(CD;T1),以及3和6个月后过渡到种植支持覆盖义齿(IOD;T2和T3)。采用以下方法评估患者的预后:迷你营养评估(MNA):评估营养状况;口腔健康影响评估(OHIP-14):衡量口腔健康相关生活质量(OHRQoL);咀嚼能力问卷:记录功能改善。结果:迷你营养评估(MNA)评分在过渡到CDs (T0-T1)后最初下降,但在种植覆盖义齿放置后稳定。据报道,咀嚼困难从基线时的91.4%下降到T3时的51.4%。T2和T3时OHIP-14评分明显提高,提示口腔健康感知改善。结论:种植覆盖义齿虽然能显著改善咀嚼能力和生活质量,但不能显著改善营养状况。研究结果强调了种植覆盖假牙对老年人的功能和心理社会益处,表明口腔康复即使没有直接的营养影响,也能提高整体健康水平。本研究基于前瞻性设计、有效的结果测量以及咀嚼能力和口腔健康相关生活质量的明确发现,提供了中等水平的证据。然而,样本量小,缺乏长期随访,营养状况没有显著改善,这表明需要进一步的研究来验证和加强这些发现。未来对更大的人群和扩展观察全种植覆盖义齿的研究对于增强证据的稳健性和普遍性至关重要。

期刊介绍: Evidence-Based Dentistry delivers the best available evidence on the latest developments in oral health. We evaluate the evidence and provide guidance concerning the value of the author''s conclusions. We keep dentistry up to date with new approaches, exploring a wide range of the latest developments through an accessible expert commentary. Original papers and relevant publications are condensed into digestible summaries, drawing attention to the current methods and findings. We are a central resource for the most cutting edge and relevant issues concerning the evidence-based approach in dentistry today. Evidence-Based Dentistry is published by Springer Nature on behalf of the British Dental Association.
