The growing field of dental implant research and development has emerged to rectify the problems associated with human dental health issues. Bio-ceramics are widely used in the medical field, particularly in dental implants, ortho implants, and medical and surgical tools. Various materials have been used in those applications to overcome the limitations and problems associated with their performance and its impact on dental implants. In this article we review and describe the fabrication methods employed for ceramic composites, the microstructure analyses used to identify significant effects on fracture behaviour, and various methods of enhancing mechanical properties. Further, the collective data show that the sintering technique improves the density, hardness, fracture toughness, and flexural strength of alumina- and zirconia-based composites compared with other methods. Future research aspects and suggestions are discussed systematically.
牙科植入物研发这一不断发展的领域已经出现，以解决与人类牙齿健康问题相关的难题。生物陶瓷在医学领域广泛应用，尤其是在牙科植入物、正畸植入物以及医疗和外科工具方面。在这些应用中已经使用了各种材料，以克服与其性能相关的局限性和问题及其对牙科植入物的影响。在本文中，我们回顾并描述了用于陶瓷复合材料的制造方法、用于识别对断裂行为有显著影响的微观结构分析，以及增强机械性能的各种方法。此外，汇总数据表明，与其他方法相比，烧结技术提高了氧化铝基和氧化锆基复合材料的密度、硬度、断裂韧性和抗弯强度。我们还系统地讨论了未来的研究方向和建议。
