Reconstructive dentistry encompasses an enormous range of treatment modalities from the restoration of single teeth to the reconstruction of the whole dentoalveolar complex in edentulous patients. Some treatment modalities have been assessed in terms of quality-of-life (QoL) outcomes and satisfaction
The aim of the present investigation was to search and review studies published between 1996 and 2006 in which the impact of the treatment was measured in terms of QoL outcome, ideally, oral health-related quality of life (OHRQoL). Patient satisfaction was also accepted as an outcome.
The primary search engine used was NICB PubMed based on MeSH headings. Hand searching of the cited references in the included papers identified a number of additional studies. The primary focus of the search was to link treatment to QoL outcomes.
The majority of included studies involved the treatment of edentulous patients, particularly the mandible. The preponderance of the studies comparing conventional dentures (CDs) and implant-supported overdentures (IODs) were randomized-controlled trials (N = 18). There was compelling evidence that patients were more satisfied with IODs than CDs. There was strong evidence that OHRQoL can be significantly improved using IODs. Evidence suggesting that one retention system is superior to another needs further clarification. Although high satisfaction ratings have been reported for maxillary implant prostheses, the overall ratings given to the maxillary implant prostheses were not significantly greater than for CDs. There was only sparce information regarding QoL or satisfaction outcomes for the majority of other forms of reconstructive dentistry.
Apart from the restoration of the edentulous mandible with IODs or CD, where there is an accumulating body of evidence on the effect of treatment choice, there are many procedures for which there are little or no such data at all. As yet, the entire range of reconstructive treatment has witnessed insufficient investigations relating treatment to its effect on QoL or satisfaction. This is an area that needs to be expanded as a way of quantifying the effect of treatment choices.
重建牙科学涵盖了从单颗牙齿修复到无牙患者整个牙-牙槽复合体重建的众多治疗方式。一些治疗方式已根据生活质量（QoL）结果和满意度进行了评估。
本研究的目的是检索和综述1996年至2006年间发表的研究，这些研究中治疗效果是根据QoL结果来衡量的，理想情况下是口腔健康相关生活质量（OHRQoL）。患者满意度也被视为一种结果。
使用的主要搜索引擎是基于医学主题词表（MeSH）的美国国立医学图书馆生物医学文献数据库（NICB PubMed）。通过手工检索纳入论文中引用的参考文献，又确定了一些其他研究。检索的主要重点是将治疗与QoL结果联系起来。
大多数纳入研究涉及无牙患者的治疗，尤其是下颌骨。比较传统假牙（CDs）和种植体支持覆盖义齿（IODs）的研究大多是随机对照试验（N = 18）。有令人信服的证据表明，患者对IODs比CDs更满意。有强有力的证据表明，使用IODs可显著改善OHRQoL。关于一种固位系统优于另一种固位系统的证据需要进一步阐明。尽管上颌种植修复体的满意度评分较高，但对上颌种植修复体的总体评分并不显著高于CDs。对于大多数其他形式的重建牙科学，关于QoL或满意度结果的信息很少。
除了用IODs或CD修复无牙下颌骨外，关于治疗选择的效果已有越来越多的证据，对于许多手术，几乎没有或根本没有此类数据。到目前为止，整个重建治疗领域在将治疗与其对QoL或满意度的影响相关联方面的研究不足。这是一个需要扩展的领域，以便量化治疗选择的效果。
