摘要

最近幾年來，牙科植體研發出不同的型態與表面結構來取代欠缺的自然牙。由於現代技術的大躍進，從外觀上來看，牙科植體已經能完全模擬單牙根的自然牙。儘管如此，在自然牙與植體之閒仍存在許多的差異，包括對咬合負荷的反應，周遭組織的微細結構，以及對於感染源的病理途徑。是否牙科植體能夠完全地取代自然牙而如同自然牙般行使功能仍是眾說紛紜。本文將會由周圍的牙周軟組織與硬組織來探討自然牙與植體之間的差異，並進一步提供臨床醫師日後可能的治療選擇。

Dental implant has been developed in different morphology and surface texture to replace the missing tooth in recent years. Due to the great advancement of modern technology, dental implant can mimic single-root natural tooth completely based on the clinical outlook. Nevertheless, there are still many different aspects between tooth and implant such as response to occlusal loading, micro-structure of surrounding tissues, and pathological pathway to infection sources. Whether the dental implant can really take the place of natural tooth and function as well as natural tooth still remains controversial. This article will explore the difference between natural tooth and dental implant from the points of periodontal hard and soft tissues surrounding to further offer the possible treatment modality for clinicians.
