Research Progress on Clinical Application of Single Implant Restoration with Different Crown-to-implant Ratios

doi:10.13701/j.cnki.kqyxyj.2018.08.003

Abstract

Abstract: Theory of crown to root ratio has an important reference value for natural teeth to assess its prognosis. However, a large number of animal experiments and clinical practice proved that it may not suit to implant. With the wide application of short implants, the correlation between different crown-root ratios of implants and implantation success rates, marginal bone resorption, and mechanical complications of implants has drawn the attention of many clinicians and scholars. This article discusses these aspects one by one.

Key words: Dental implants, Short implants, Marginal bone loss, Crown-to-implant ratio
