Dental treatment method and abutment used therein

Abstract

A dental treatment method is provided. In this method, a tooth of a patient is extracted and prepared to provide a root part. A root canal in the extracted tooth is prepared and treated. A post of an abutment is fitted into the root canal to attach the root part to the abutment. The abutment having the root part is attached to a dental implant. With the root part attached to the abutment, periodontal connective tissue maintains the jaw bone associated with the extracted tooth, without significant hard tissue loss.

1 .- 11 . (canceled) 
     
     
         12 . A method of manufacturing an abutment for a dental implant, the method comprising:
 obtaining data associated with the dentition of a patient;   generating a model of the abutment through a computer-implemented process based on the data; and   processing a material based on the model to generate the abutment, wherein the abutment is configured to match the analogue of a predetermined tooth of the patient, such that, after the predetermined tooth is extracted and prepared to provide a root part, the root part is attached to the abutment during osseointegration.   
     
     
         13 . The method of manufacturing an abutment of  claim 12 , wherein the data used is based on the average human tooth size and shape, such that the abutment can be prefabricated. 
     
     
         14 . The method of manufacturing an abutment of  claim 12 , further comprising cleaning and preserving the abutment. 
     
     
         15 . An abutment for a dental implant, the abutment comprising:
 an apical end and a coronal end opposite the apical end;   an insertion portion at the apical end, the insertion portion being configured to be received in an opening of the dental implant;   a transition portion coronal of the insertion portion; and   a connecting portion extending coronally of the transition portion, wherein the connecting portion is configurable to be attached to a root canal or tooth structure of an extracted tooth of a patient.   
     
     
         16 . The abutment of  claim 15 , wherein the insertion portion comprises an anti-rotation element, the anti-rotation element having a plurality of recesses and protrusions arranged alternately. 
     
     
         17 . The abutment of  claim 15 , wherein the transition portion has a conical shape. 
     
     
         18 . The abutment of  claim 15 , further comprising a shoulder portion coronal of the transition portion, wherein the shoulder portion is customarily configurable to match the analogue of the extracted tooth of the patient. 
     
     
         19 . The abutment of  claim 15 , wherein the abutment is manufactured using a CAD/CAM process.
