13. The method according to claim 1, wherein the superstructure is made prior to placement of implants, and wherein the superstructure is fixed on the implants before they have grown in, either immediately after or shortly after the placing of these implants, whereby the superstructure functions as an element for the application of an immediate loading technique. Description
CROSS REFERENCE TO RELATED APPLICATIONS This application is the U.S. National Stage of International Application No. PCT/BE2004/000024, filed Feb. 23, 2004, which, in turn, claims the benefit of Belgian patent application 2003/0132, U.S. provisional patent application No. 60/450,672, and U.S. provisional patent application No. 60/495,731 filed Feb. 28, 2003, Mar. 3, 2003, and Aug. 18, 2003, respectively.
Recently, however, there is a tendency to refrain from letting the implants grow in for three to six months, and to immediately put a load on them, what is called �immediate loading�.
an accessory in the shape of a drill jig in which one or several ducts are formed for drills, which are provided in the drill jig in function of the computer planning; an accessory in the shape of a drill jig in which one or several ducts are formed for drills, which are provided in the drill jig in function of with respect to the computer planning, whereby means are also used in combination with at least one of these ducts, which make it possible to successively work with different drill diameters in one and the same duct; an accessory as in the preceding paragraph, whereby the ducts have openings in which above-mentioned means can be placed, which make it possible to successively work with different drill diameters and whereby these means consist of interchangeable bushes with openings or passages of different diameters; an accessory as in the preceding paragraph, whereby the ducts are laterally open to allow lateral insertion of a drill and whereby the interchangeable bushes preferably are placed over the drill prior to insertion and placed in the duct while drilling to provide guidance an accessory in the shape of a drill jig which is configured such that it also serves as a fitting jig; an accessory in the shape of a drill jig which is configured such that it also serves as a positioning jig, and in particular can be used to force the implants into the required position after they have been placed; an accessory which is made as a positioning jig which allows to force the forcing of the implants into the required position after they have been placed; an accessory according to any of the two preceding paragraphs, whereby said the accessory is provided with passages for screws that can be screwed into the implants, whereby these passages and the accompanying screws have such a shape that, when the screws are tightened, they can be forced into a specific position; an accessory which is made as an intermediate positioning jig which has at least features which allow for a connection with at least one implant that has already been placed, and which also has features forming a duct for a drill and/or an implant or features forming an implant placed on an implant holder. Other details and advantages of the invention will emerge from the description that follows, as well as from the attached claims.
According to a variant of the method, instead of realizing this diagnostic setup in a mechanical articulator, the test arrangement can also be made virtually, with a computer, by means of what is called a �virtual articulator� which can simulate the movements of the upper jaw in relation to the lower jaw.
If, as represented, the drill jig 6 is also used as a fitting jig, all the bushes 16 are unscrewed from the drill jig 6 before the implants 7 are placed, and implant holders 19�whose outer diameter corresponds to the inner diameter of the bushes 14�are put on the implants 7. When an implant 7 is placed through the opening 13, the duct guides the implant 7.
Drilling of the holes 11 and placing of the implants 7 �as such� can never be performed with the required precision to allow immediate placement of a premanufactured superstructure: the implants 7 will be positioned accurately within a couple of tenths of a millimeter at the most in relation with regards to the planning.
The lower side of the positioning jig 24 must not necessarily be adjusted to the shape of the bone 5 or possibly the gums 2 of the patient. As the drilling and the implant placement have been done in function of the patient, the positioning jig 24 is only necessary for fine-tuning the positions. The small adjustments will assure a perfect correspondence between the implants 7 and the superstructure at fixture level or alternatively�if abutments are used�at abutment level.
Also, holes 38 are left in the digital cast 35�based on the computer planning�in which implant replicas 39 can be fixed.
A mold of the teeth 37 in the setup 40 is made which will further be referred to as �key� 41. This key 41 has a part 42 which precisely delineates the gums 2.
