Description of reference numerals: 1 tubular part, 11 fixing sections, 12 gum supporting sections, 13 axial through channels, 14 internal thread sections, 131 limiting sections, 18 extending parts, 19 supporting parts, 8 implants, 9 screws and 91 nuts.
Detailed Description
The utility model is described in detail below with reference to the following description of the drawings:
as shown in fig. 1-5: an implant-based attached gingiva extender, comprising a tubular portion 1, the tubular portion 1 having an axial through channel 13 for the passage of a screw 9;
the proximal end of the tubular portion 1 is provided with a plurality of outwardly extending, horizontally supported supports 19;
the tubular part 1 is divided into a fixed section 11 and a gum supporting section 12, the fixed section 11 is arranged in the implant 8 through the proximal opening of the implant 8, and the outer contour of the fixed section 11 is matched with the inner contour of the implant 8;
the screw 9 is connected to the implant 8 through the axial through channel 13, thus fixing the tubular portion 1 to the implant 8; is fixed to the tubular part 1 of the implant 8 with its gingival support section 12 extending beyond the proximal end surface of the implant 8.
The fixing end of the tubular part 1 is here intended to ensure that the tubular part 1 is inserted into the implant, after which the tubular part 1 is fixed to the implant 8 by means of screws 9 so that both are formed as one piece.
Wherein the gum support section 12 provides vertical support for attached gum growth; the support portion 19 provides horizontal support for attached gum growth.
The number of the supporting parts 19 is four, and the included angle between any two adjacent supporting parts 19 is 90 degrees.
The outer end of the support portion 19 is provided with an extension portion 18 extending downwards such that the angle between the support portion 19 and the extension portion 18 is 90 deg.. The structure can play a role in shaping the inner form of the dental arch of the new soft tissue.
The support 19 and the extension 18 present an arc transition.
A limiting closing-in 131 is arranged in the axial through channel 13, and the opening of the closing-in is gradually reduced from near to far; the far end contour of the nut 91 of the screw 9 is similar to the closing-in contour; so that the proximal end face of the screw 9 is flush with the proximal end face of the tubular part 1 after the nut 91 is brought into contact with the constriction 131.
The structure is used for limiting the screw 9 and driving the tubular part 1 to advance towards the far end when the screw 9 advances towards the far end, so that the tubular part 1 compresses the implant 8, and the outer contour of the fixing section 11 is matched with the inner contour of the implant 8, so that the sealing property between the tubular part 1 and the implant 8 can be ensured.
The distal inner side wall of the axial through channel 13 is provided with an internal thread section 14 cooperating with the thread of the screw 9. The direction of the screw 9 can be guided by the internal thread section 14.
The method comprises the following specific operation steps:
1) incise the attached gingiva from the right middle of the operation area, not incise the periosteum, and strip the mucosa above the periosteum.
2) And taking out the covering screw.
3) A gum extender with proper specification is selected and placed above the implant, and the screw 9 is locked.
4) The upper part of the attached gingiva extender is covered with gelatin sponge or soft tissue growth factor, and the gingiva extender is not pulled together for suturing.
5) The suture was removed half a month later.
According to the utility model, the implant is used as a time node of the second stage, the stable implant is used as a bottom support, the attached gingiva is pushed away by a tool without being drawn together for suturing, and soft tissue growth promoting factors are placed on the surface of the wound to widen the attached gingiva. Of course, the premise is that the implant area has narrow attached gingiva, but it is only necessary to widen the gingiva to ensure that there is 2mm attached gingiva around the implant, rather than no gingiva attached at all.
The present invention substantially ensures that at the present stage the dental implant system can be used in such a way as to augment the soft tissue.
In summary, the structure of the present invention has the following features:
1. operating time points: and in the second stage of planting operation.
2. Indications are as follows: the operating field itself has narrow attached gingiva, only needs to widen the gingiva, not the case of completely not attaching gingiva.
While the utility model has been illustrated and described with respect to specific embodiments and alternatives thereof, it will be understood that various changes and modifications can be made without departing from the spirit and scope of the utility model. It is understood, therefore, that the utility model is not to be in any way limited except by the appended claims and their equivalents.
