[1]. The use of polymer materials is more diverse than metal implants, although their interchangeability is not great. In most cases, polymers do not compete with other types of material and are highly specialized and poorly interchangeable. Their unique properties are flexibility, resistance to ...
The buccal cusp of the mandibular implant crown is located toward the original central fossa of the natural tooth. The medially positioned division B mandibular implant crown may have a central fossa, but it is more lingual than the original position. The lingual contour of the crown is ...
A comparative biomechanical study of original and compatible titanium bases: evaluation of screw loosening and 3D-crown displacement following cyclic loading analysis. J Adv Prosthodont 2022; 14: 70-77. Kim E-S, Shin S-Y. Influence of the implant abutment types and the dynamic loading on ...
In order to investigate the influence of abutment material on the stress of implant-supported all-ceramic single crown, a 3D finite element model of implant-supported mandibular first premolar was computed by COSMOS/M 2.85 software. Alumina, zirconia, and titanium were used as abutment materials re...

Researchers used spark plasma sintering to fabricate bilayered, single-piece Ti6Al4V-yttria stabilized zirconia (YSZ) dental implants. The bilayered component’s Ti6Al4V and YSZ portions function as the fixture and crown, respectively, resolving issues with traditional two- or three-piece implants. ...
It works as an anchor for the implant abutment that connects the implant to the prosthetic crown. Since there are different types of implants and prosthetic crowns, connectors come in different shapes, such as hexagonal, octagonal, conical, ball-shaped, and tri-lobe. What's important is that ...
The strength of the implant material in this range does not depend on the frequency but on the number of cycles, and we have simplified the bone to a linear elastic one. The statically calculated stress represents the situation for the maximum value in the unidirectional bending, i.e. ...
Theimplant abutmentlinks the implant fixture to the restoration. Abutments are available in a variety of different types, each designed to manage a particular clinical situation (Fig. 17-3B,C). The abutment provides an area of retention similar to a prepared tooth forcementationof a crown. Some...
(Steinemann, 1998; Okazaki and Gotoh, 2005). Other types of titanium alloy include Ti6Al7Nb and titanium-zirconia alloy (TiZr). Unlike Ti–6Al–4V, TiZr is regarded as a stronger material and is now commonly used in dental implants, in particular in narrow diameter dental implants where ...
