ABUTMENT CAPABLE OF ACCOMMODATING CORE CROWNS MANUFACTURED AT VARIOUS ANGLES AND FUNCTIONING AS A HEALING ABUTMENT HAVING A CAP ATTACHED THERETO, METHOD FOR MANUFACTURING DENTAL IMPLANT PROSTHESES USING THE ABUTMENT, AND METHOD FOR IMPLANT SURGERY USING THE ABUTMENT
First Claim
1. Abutment that accommodates core crowns manufactured in various angles and functions as healing abutment with the cap, comprising:
- a central through-hole 31 of the abutment 3 that penetrates the middle area of the abutment 3 from the upper portion to the lower portion thereof;
a connecting screw 2 inserted into the central through-hole 31 of the abutment 3 in order to be connected a fixture;
an upper portion 39 of the abutment 3 that forms the border of the central through-hole 31;
an inner upper portion 32 of the abutment 3 that is formed at the inner lower portion of the upper portion 39 of the abutment 3 and provided with a slop;
a lateral upper portion 36 and a lateral lower portion 35 of the abutment 3 which are formed upwardly and downwardly on the basis of a vertex projecting from the side surface of the abutment 3 and provided with a slop, respectively.

Abstract
The present invention relates to an abutment capable of accommodating core crowns manufactured at various angles and functioning as a healing abutment having a cap attached thereto, to a method for manufacturing dental implant prostheses using the abutment, and to a method for implant surgery using the abutment wherein the abutment consists of an artificial tooth crown (core crown) for an abutment formed in an upper portion of a fixture and is directly bonded using cement rather than using a healing abutment, and grooves are further formed in the upper portion of the abutment and the lower portion of the crown so as to widen the contact area between the abutment and the crown, and the abutment has a protrusion at a side surface thereof.

7. Implant method using the abutment that accommodates core crowns manufactured in various angles and functions as healing abutment with the cap, comprising the steps of:
-
forming installation groove in order to place a fixture to the alveolar bone where tooth is missing by using drill or other equipments; placing the fixture in the installation groove; coupling the abutment that can accommodate core crowns manufactured in various angles and functions as healing abutment with the cap, to the fixture; placing an abutment cap on the upper portion of the abutment; stitching the gum on the lateral area in order to prevent fissure and completing the surgery; after three to five months, removing the abutment cap and putting an impression cap in its place; making an dental impression for teeth that are nearby and the area that impression coping was placed; sending the dental impression and the impression cap to the processing room; creating a working model made of plaster by using an implant analog to be inserted in the same spot as the fixture in the mouth and placing wax sculpted artificial crown on top of the implant analog of the working model; placing sculpted wax crown in dental investment material to make a cast artificial crown or scanning wax artificial crown to create the artificial crown; removing the abutment cap inside the mouth of the patient and adhering the artificial crown on top of the abutment with cement as part of the implant procedure.
