Root apex surgery guide plate and manufacturing method thereof

Abstract

The invention provides a root apex surgery guide plate and manufacturing method. The root apex surgery guide plate can simultaneously indicate a root apex excision range and a soft tissue incision, and comprises a tooth supporting part, a root cutting guide plate part and an incision guide plate part; the tooth supporting part, the root cutting guide plate part and the incision guide plate part are detachably connected; the tooth supporting part is connected with the root cutting guide plate part and the incision guide plate part through connecting parts. According to the digital root apex surgery guide plate and the manufacturing method, the position of the incision and the position of a root cutting region can be accurately guided at the same time, and a surgery wound is reduced; and by using a detachable design, the guide plate can be attached to bone tissue for accurate guiding; and the root apex surgery guide plate has application advantages especially when root apexes of multiple anterior teeth undergo surgery or anterior tooth roots have undercuts.

Description

technical field [0001] The invention belongs to the field of oral medical instruments, and in particular relates to an apex surgery guide plate capable of simultaneously indicating the range of apex resection and soft tissue incision and a digital manufacturing method thereof. Background technique [0002] Apical surgery can save a large number of teeth that still have refractory apicitis after conventional root canal treatment, or have post-core restorations that are difficult to implement root canal retreatment. However, when multiple teeth require root apical surgery, especially in the anterior aesthetic area, there are often two major problems: 1) Due to factors such as incision design and large flap area, postoperative gingival scars or gingival margins, Problems such as poor shape of the gingival papilla affect the appearance of the soft tissue of the anterior teeth; 2) It is difficult to accurately determine the range of root removal and bone removal of multiple affec...

AI Technical Summary

Problems solved by technology

However, when multiple teeth require root apical surgery, especially in the anterior aesthetic area, there are often two major problems: 1) Due to factors such as incision design and large flap area, postoperative gingival scars or gingival margins, Problems such as poor shape of gingival papilla affect the appearance of the soft tissue of the anterior teeth; 2) It is difficult to accurately judge the extent of root removal and bone removal of multiple affected teeth, which increases the trauma of hard tissue during surgery

[0003] Although the existing apical surgery guides (including digital apical surgery guides) can locate the location of apical lesions, there are three problems: 1) the lack of soft tissue guides to indicate the position of the incision; 2) the part to indicate apical resection There is a distance from the bone surface, and there is no precise guidance through the design that fits with the bone tissue; 3) It is not suitable for the case where there is a large undercut at the root of the affected tooth, and the guide plate cannot be worn at this time
