Abstract

Disclosed is an implant scan body unit which comprises: an analog implanted into an impression body prepared by modeling an oral cavity shape of a patient; a scan body fastened to an upper part of the analog; and a guide part coupled to an upper part of the scan body.

Description

Based on the different groove structure for each height of the implant scan body, the scan body for implants shortens the impression or human taking process and increases the accuracy {IMPLANT SCAN BODY}

The present invention relates to a scan body for implants, and more particularly, to a scan body for implants used to acquire intraoral design data for implant production.

In general, a dental implant refers to an artificial tooth structure formed by planting a fixture, which is an artificial root, in a part where teeth have been partially or completely lost, attaching it to the alveolar bone, and fixing a dental prosthesis to the artificial root. do.

Since it is important to accurately position the prosthesis according to the shape of the patient's oral cavity in such an implant procedure, the prosthesis is manufactured based on taking an impression of the patient's oral cavity.

The impression taking step can be largely divided into an analog method of manually forming a mold using impression coping and a digital method of acquiring a three-dimensional image with an intraoral scanner using a scan adapter.

The general impression taking step is divided into 14 steps, for example, removal of the healing abutment placed on the fixture after the second operation of fixture placement, impression coping directly on the fixture placed on the alveolar bone or binding using a guide pin, This is achieved through a series of processes such as applying the impression material, removing the hardened impression material, and pouring gypsum to make a working model.

This step of taking impressions required several dental patient visits, and it was difficult to visually find the part where the error occurred in the 14 steps and the problem that the procedure was cumbersome. Even if a small error occurs during each step, the suitability of the implant prosthesis in the patient's oral cavity remarkably deteriorates, resulting in low-quality implants.
