生物医学研究寻求产生可转化为临床环境的实验结果。为了改善从长凳到床边的过渡,研究人员必须根据适当模型的数据得出合理的结论。作为人类临床暴露的先决条件,动物测试在一系列物种中进行,从实验室小鼠到较大的动物(如狗或非人类灵长类动物)。小型猪似乎是研究口腔内种植体周围骨手术的首选动物。狗模型在牙科种植研究领域是众所周知的,现在往往被用于在受损的口腔条件(生物膜)下进行的研究。关于小动物模型,研究大多使用啮齿动物,对兔子模型的兴趣下降。小鼠模型仍然是遗传学研究的参考。另一方面,在过去的十年里,科学的进步和政府的指导方针导致了所有动物模型在牙科种植研究中的替代、减少和改进。在新的开发战略中,一些体内实验正在逐步被体外或生物材料方法取代。在这篇综述中,我们总结了目前可用于牙种植体研究的动物模型的关键信息,并强调(I)每种类型的利弊,(Ii)关于研究目标的决策程序的新水平,以及(Iii)动物研究的展望,讨论可能的非动物选择。
Biomedical research seeks to generate experimental results for translation to clinical settings. In order to improve the transition from bench to bedside, researchers must draw justifiable conclusions based on data from an appropriate model. Animal testing, as a prerequisite to human clinical exposure, is performed in a range of species, from laboratory mice to larger animals (such as dogs or non-human primates). Minipigs appear to be the animal of choice for studying bone surgery around intraoral dental implants. Dog models, well-known in the field of dental implant research, tend now to be used for studies conducted under compromised oral conditions (biofilm). Regarding small animal models, research studies mostly use rodents, with interest in rabbit models declining. Mouse models remain a reference for genetic studies. On the other hand, over the last decade, scientific advances and government guidelines have led to the replacement, reduction, and refinement of the use of all animal models in dental implant research. In new development strategies, some in vivo experiments are being progressively replaced by in vitro or biomaterial approaches. In this review, we summarize the key information on the animal models currently available for dental implant research and highlight (i) the pros and cons of each type, (ii) new levels of decisional procedures regarding study objectives, and (iii) the outlook for animal research, discussing possible non-animal options.
