Method for processing bone graft material using teeth, and bone graft material processed thereby

Abstract

The present invention relates to a processing method for bone graft material using teeth by separating an extracted tooth by region and processing the extracted tooth to allow regional powders to be independently used or mixed depending on a use such as grafting or enhancement of alveolar bone, and a bone graft material processed thereby. The processing method for bone graft material comprises the following steps: (a) cutting a tooth extracted from a patient at the boundary between the crown of a tooth and the root of a tooth,(b) removing the missing region of the horizontally cut crown of a tooth, soft tissue and pulp tissue,(c) quick-freezing the tissue of the crown of a tooth and pulverizing the same to prepare a powder having an average diameter of 200-1,500 [mu]m,(d) degreasing the powder,(e) dehydrating the powder,and (f) carrying out a post-process including at least a sterilization with respect to the degreased and dehydrated powder to prepare a bone graft material.

Description

technical field

[0001] The present invention relates to a bone graft material, and more particularly to a method for processing a bone graft material using teeth and a bone graft material processed therefrom. The method for processing the bone graft material distinguishes extracted teeth according to different parts and processes them into Powder, so that it can be used independently or mixed according to the use of alveolar bone grafting or alveolar bone enhancement. Background technique

[0002] Recently, the popularized dental implant surgery has shifted towards immediate implant after tooth extraction, in which damaged alveolar bone must be preserved and strengthened.

[0003] The bone graft materials used for the preservation and enhancement of alveolar bone in implantation include artificial bone, xenograft bone or allograft bone. These artificial bone, xenogeneic bone or allograft bone graft materials cannot replace autologous bone graft materials, and almost most of...

Examples

Embodiment 1

[0055] Example 1: Enamel powder

[0056] An example in which a crown of an extracted tooth is processed into powder will be described.

[0057] First, the image 3 The extracted tooth is shown in the Figure 4 and Figure 5 The interface between the crown and the root shown is truncated, and the extracted tooth is a pretreated tooth, and the above pretreatment is to remove the extracted caries or inflammation and other defective parts.

[0058] Such as Figure 6 As shown, after removing the soft tissue and pulp tissue in the crown, wash with distilled water for 30 minutes to 2 hours. Such as Figure 6 As shown, enamel and dentine remain in the crown after removal of soft tissue and pulp tissue.

[0059] Use liquid nitrogen from -160°C to -210°C, for example Figure 6 The dental crowns treated as shown were subjected to rapid freezing for 30 minutes to 2 hours, and then crushed with a pulverizer (Crushing), so that they were processed into such Figure 7 Powders with ...

Embodiment 2

[0068] Embodiment 2: dentin powder

[0069] An example in which a root of an extracted tooth is processed into a powder will be described.

[0070] First, the image 3 The extracted tooth is shown in the Figure 4 and Figure 5 The interface between the crown and the root shown is truncated, and the extracted tooth is a pretreated tooth, and the above pretreatment is to remove the extracted caries or inflammation and other defective parts.

[0071] Such as Figure 6 As shown, after removing the soft tissue and pulp tissue in the tooth root, wash with distilled water for 30 minutes to 2 hours. Such as Figure 6 As shown, dentin and cementum remain in the root after removal of soft tissue and pulp tissue.

[0072] With methods such as quick freezing of embodiment 1 and pulverizing dental crown, process such as Figure 6 The tooth roots shown were treated to make a powder with an average particle size of 200 to 1500 μm.

[0073] Using the same method as in Example 1, th...
