Technical field

The present invention relates to the fields of dental implant.

Background technique

The reparation supported using adjacent and/or opposite tooth by dental implant is by thousands of clinical doctor It is raw to execute.Exemplary repair process is shown in Fig. 1 a-1d.A referring to Fig.1, alveolus 10 are formed in the jawbone 15 of patient To adapt to dental implant fixture 20.(show in Figure 1b once dental implant fixture 20 is fixed in alveolus 10 Out), base member 25 just couples (showing in Fig. 1 c-1d) with dental implant fixture 20.In tooth mould (tooth Analogue) 30 with after the coupling of base member 25, and repair process is completed.

In view of nearest research, it has been determined that show planting with some of monodentate and/or multiple tooth implant reparation Enter the shadow of the aesthetic beauty of the slightly continuous craniofacial growth of generation after body reparation is performed, functionality, prosthetic and/or periodontal It rings.

Craniofacial growth can for example, by cause occlusion variation, cause then influence open contact tooth migration, And/or causes the variation of labial teeth aesthetics and influence the relationship of implant reparation Yu remaining tooth and jaw structure.

The variation of occlusion can be the continued growth due to the dental arch comprising implant and opposite dental arch.In two kinds of feelings Under condition, the position of implant and associated reparation is static, however tooth is subjected to facial direction and occlusion two, direction side To movement.These potential variations are not sex-specifics.For such as supporting the rear free end of significant biting load to plant Enter the case where body is repaired, these movements can offset the effect of implant reparation with the time, unfavorable stress is placed in remaining In dentition.

When natural tooth and dental implant are there are in identical dental arch, many people have been observed that unforeseen length Phase complication is the opening of implant reparation with the naturally interdental contact for being typically implanted body reparation front.Losing nature In the case where tooth, the nearly middle contact of implant reparation is significantly affected by the situation at age and opposite dentition.

Other than the result of the occlusion and opening of changes of function and contact, it has been observed that with the slightly growth of time The aesthetic results for once thinking stable can be changed.It is uncoordinated to become in three visibility regions relative to adjacent teeth It is obvious: incisxal edge length, gingival margin height and face contour alignment.The extrusion of labial teeth and uprightly it can cause simultaneously all three not Coordinate.Lip on implant or matrix is soft/and the thinning of sclerous tissues may be with the further of this slightly growth course As a result.

The uncoordinated of face alignment of implant reparation before relatively more lips carry out suitably may be modified or be corrected Or suitably may not be modified or be corrected, depend not only on the seriousness of generation and also depend on as implant axially aligns, Such factor that available soft tissue depth and implant are positioned in lip/palatine of chi chung.The gum bead of implant reparation Gradually uncoordinated between (cervical gingival margin) and the gum bead of adjacent natural tooth may be not allow The aesthstic complication easily solved.

In view of the foregoing, there are the needs to improved dental implant.
