DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a superstructure for an endosteal dental implant as well as an orthodontic device with such a superstructure mounted on a dental implant.
BACKGROUND OF THE INVENTION
The amount of orthodontic treatments of adults and adolescents to correct the dental position is increasing. So far the corrections of the dental position have been undertaken partially by means of a head-gear through which the forces on the bows and clasps which lie close to the teeth may be applied. The head-gear will act on the rows of the teeth about 8 hours as a general rule. The head-gear is therefore only intermittently effective and is felt by the bearer as extremely cumbersome.
SUMMARY OF THE INVENTION
An object of the invention is to produce a superstructure for an endosteal dental implant which serves as an anchorage for the introduction of the forces in orthodontic corrections.
The advantages achieved by the invention are basically as follows:
No head-gear has to be applied what represents a considerable improvement of the comfort;
The translation force (anchorage) is not only intermittently effective but permanent for 24 hours; and
As the superstructure may be attached as an anchorage at any arbitrary anatomical position where a dental implant may be fixed the orthodontic wires may be attached not only at the outer sides of the teeth (buccal) but also at the inner sides of the teeth (lingual).
This offers advantages of esthetics which are to be rated high above all else in the treatment of adults.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention and embodiments of the invention are discussed in more detail in the following with reference to the accompanying schematic drawings thereof wherein:
FIG. 1 is an exploded side elevation in a longitudinal section through the orthodontic device according to the invention;
FIG. 2 is a top plan view of the superstructure of the orthodontic device according to FIG. 1;
FIG. 3 is a sectional side elevation of the superstructure of the orthodontic device according to FIG. 1; and
FIG. 4 is a longitudinal section through the dental implant of the orthodontic device according to FIG. 1.
DESCRIPTION OF PREFERRED EMBODIMENTS
The orthodontic device illustrated in FIG. 1 basically consists of a superstructure mounted on an endosteal dental implant 2 in which (as shown in FIG. 1) an orthodontic element 6 e.g. a wire is either attached with a screw 7 or is adherable without the screw at its area 4.
For better orientation some geometrical elements of the superstructure are defined in the following:
A) a longitudinal axis 11 coaxial to the dental implant 2;
B) an outer surface area 12 having buccal, lingual, mesial and distal areas; and
C) an annular shoulder 8 orthogonal to the longitudinal axis 11 suitably position for connection to the dental implant 2.
In the buccal and lingual area of the surface area 12 areas 4 are provided which extend parallel to the longitudinal axis 11 and are flattened opposite the maximum outer diameter 3 on which orthodontic brackets (particularly adhesive-brackets) or square bows are attachable. For this purpose the areas 4 are preferably planar polished and roughened. The roughness R.sub.a of the area 4 lies preferably in the range of from 3.3 to 12.5 .mu.m. Additionally retentions 20 preferably with the shape of grooves can be inserted in the area 4.
The superstructure 1 further provides passing slots 5 running from the mesial to the distal area of the surface area 12 wherein orthodontic wires 6 can be inserted from above and be radially and axially fixed by means of the screw 7. Instead of the screw 7 naturally other known fixation systems e.g. bayonet joints or glued joints can be employed.
In case of the employment of a screw 7 the superstructure 1 has coaxial to the longitudinal axis 11 an internal thread 16 whereto the screw 7 which is provided with a corresponding external thread 17 is insertable.
To ensure a rotation stable junction of the superstructure 1 with the endosteal dental implant 2 the superstructur
