Method of manufacturing crown for dental implant and crown thereby

Abstract

A method of manufacturing a crown for a detachable dental implant includes providing a first preliminary body including a preliminary space and a preliminary post extending downwardly from a ceiling of the preliminary space by using a block including zirconia. The method also includes machining an outer surface of the first preliminary body to form a second preliminary body including a preliminary chewing surface. The method additionally includes sintering the pre-machining crown to form a crown, in which through the sintering, the crown may include an accommodation space for accommodating an upper portion of a dental implant and a fixation post extending downwardly from a ceiling of the accommodation space. A dimensional ratio of the accommodation space to the preliminary space may be the same within an error of ±1% as a dimensional ratio of the fixation post to the preliminary post.
