Description
Technical field
The utility model belongs to field of oral cavity medical equipment, more particularly, to a kind of tip of a root surgical operation guide plate.
Background technique
Root canal therapy is the prefered method for treating dental pulp disease, periapical disease, can solve its most problems, still,
Due to the complexity of root canal anatomy system, there are still limitations for clinical diagnosis and operating technology.Research is pointed out, according to basic principle
After strictly carrying out mechanical preparation, chemical disinfection and close packing to root canal, 87%~92% success rate can be obtained.It is so surplus
Under 8%~13% need to carry out root canal surgical operation therapy, one of the most common is tip of a root surgical operation.
Tip of a root surgical procedure includes: that incision turns over valve, goes fenestration, periapex to scrape to control, root resection, detect, root canal
Retrograde preparation, root canal, which are driven in the wrong direction, to be filled, sutures.The positioning when difficult point of tip of a root surgical operation is fenestration to apical area, when
Periapex determines that there are certain difficulty, blindness ground auger mill in the position for suffering from apex radicis dentis and disease damage area without disease damage and when complete cortex bone
It may damage and suffer from root and adjacent teeth root of the tooth.Under normal conditions, tooth can be substantially determined according to the dissection external form of root of the tooth, preoperative X-ray film
The position of root long degree, the tip of a root first removes the sclerotin at the nearly tip of a root in art to the exposure of root face, bones directly then along the trend of root of the tooth
To tip of a root exposure.Such operation is limited by conditions such as surgical field of view, will increase the damage to bone tissue, extends Wound healing
Time, be easy to bring in some arts and postoperative complications, and technique sensitive with higher.
Yang Xue superfine ([J] dentistry research, 2016,32 (9): 944-948.) utilizes tip of a root surgical operation for the first time
Guide plate row minimally invasive apical leakage, precise ablation tip of a root diseased region farthest reduce the damage to bone tissue, while letter
Operate in art, shorten treatment time in art, the satisfaction and comfort level of patient is improved.But the tip of a root surgery hand
Though art guide plate can realize positioning function, it can not directly judge whether the guide plate is bonded completely with the tooth jaw of patient, doctor can only
Judged by observation guide plate Marginal microleakage or shaking guide plate.
Therefore, develop it is a kind of can the tip of a root surgical operation guide plate of compactness of simple judgment and tooth jaw there is great research
Meaning and clinical value.
Summary of the invention
The purpose of the utility model is to overcome what tip of a root surgical operation guide plate compactness in the prior art can not judge to lack
It falls into, a kind of tip of a root surgical operation guide plate is provided.Tip of a root surgical operation guide plate provided by the utility model can be by being arranged retention finger
