A kind of root tip operation guide plate and manufacturing method thereof

Abstract

The present invention provides a guide plate for root apex surgery and a manufacturing method thereof. The guide plate for root tip surgery can simultaneously indicate the range of apex resection and soft tissue incision, and includes a tooth support part, a root cut guide plate part and an incision guide plate part. The tooth support part, The root cutting guide plate part and the incision guide plate part are detachably connected, and the tooth support part is respectively connected with the root cutting guide plate part and the incision guide plate part through the connection part. The digital apical surgery guide plate and production method provided by the present invention can accurately guide the position of the incision and the root cutting area at the same time, reducing surgical trauma; the detachable design can make the guide plate fit the bone tissue for precise guidance, It has application advantages especially when there are multiple anterior root apex operations or undercuts on the anterior root side.

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...

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
