Abstract: A dental prosthesis includes an implanting end, a coupling end, and a screw portion between the implanting end and the coupling end. The dental prosthesis further includes a positioning marker portion located adjacent to the coupling end of the dental prosthesis. The dental prosthesis can be precisely located in an alveolar bone of a patient. A dental implant includes the dental prosthesis and an abutment. The abutment includes a prosthesis coupling end. The prosthesis coupling end of the abutment is coupled to the coupling end of the dental prosthesis.

Abstract: A bone implant includes an implant having an implantation end and a connection end. A blind hole is formed in the connection end and extends in an axial direction, defining an abutment receiving section and a locking section. The abutment receiving section includes an anti-rotation portion having a minimal inner width perpendicular to the axial direction. An abutment includes an elastic, deformable portion, a connection portion, and a prosthesis engagement portion. The abutment further includes a bore extending in the axial direction. The elastic, deformable portion includes resilient plates, with a slit formed between two adjacent resilient plates. The elastic, deformable portion has a maximal outer width larger than the minimal inner width. The elastic, deformable portion is aligned and engages with the anti-rotation portion. An abutment screw includes a head end positioned in the bore of the abutment and a locking end engaged with the locking section.

Abstract: A heat dissipation module configured on a substrate having a heat producing element thereon includes a holder configured on the substrate and a heat sink having a base opposite to the heat producing element and pivotally connected to the holder and capable of joining to the substrate with the heat producing element covered by the base.
