摘要：Cone-in-cone (ACone-in-cone) is a term used to describe a To keep implant-supported definitive fixed dental prostheses in place, a Morse taper connection between abutments and crowns has been proposed (FDPs). This "Conometric Concept '' prosthetic method was employed to keep both lithium disilicate (LS2) and zirconia restorations in place. A cone-in-cone connection between an abutment and the appropriate coping is used in the conometric concept to preserve an implant-supported restoration without the need of fasteners or cement. Prefabricated components are used to ensure a perfect fit between the abutment and the restoration. The friction between the abutment and the titanium coping allows the conical coupling abutments to maintain a prosthesis without the use of cement. There are no access holes in the restoration, and it can be simply removed with a spring-loaded partial denture remover.Without the chance of cement remaining at the abutment coping interface, the restoration's emerging profile can be placed subgingivally. The major goal of this research is to examine the clinical efficiency of the conometric idea by critically reviewing studies that have employed it. Up until the present, an electronic search was conducted in PubMed, Google Scholar, and the Cochrane Library. Predetermined selection criteria were used to appraise the papers. The research comprised randomized, non-randomized, prospective cohorts, prospective clinical trials, and in vitro studies. This review did not include case studies, case reports, conference papers, or animal research. The possibility of bias was assessed, and the results were compiled. The conometric idea offers a positive clinical outcome as a prosthetic therapy alternative, according to the conclusions of this review. To determine its viability as a commercial treatment option, more long-term research is required.
