Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to dental medical instrument technical field, especially a kind of apex barrier filler for iRoot BP Plus. BACKGROUND
[0002] Young permanent teeth refer to permanent teeth that have been erupted for about 3-5 years and the root apex has not been developed completely. Permanent teeth reach the appropriate length after 2-3 years of eruption, and the root apex is developed completely after 3-5 years. Once the young dental pulp is completely necrotic, the tooth root stops developing and becomes short and open.
[0003] Biological materials are widely used in the field of dentistry. Commonly used are MTA and iRoot BP Plus, which are used in common dental procedures such as direct pulp capping, root canal therapy, and apex surgery. Among them, MTA is wet sand after mixing, and has poor plasticity and operability. iRoot BP Plus is in paste form, and has relatively good plasticity, but still has problems such as sticking to instruments and poor operability. The existing dental biological material delivery device needs to fill the clinical application scenarios of biological active materials: pulp chamber bottom perforation repair, root canal perforation repair, apex barrier surgery, direct pulp capping, etc.
[0004] For young permanent teeth apex barrier surgery, the currently used apex barrier filler
[0005] 1. The length and fineness are not enough, and iRoot BP Plus cannot be delivered to the root apex for a relatively thin root apex hole.
[0006] 2. The working end is made of metal material. Since iRoot BP Plus material is relatively soft, it cannot be compacted to achieve the effect of sealing the root apex.
[0007] 3. The filler is repeatedly sterilized and deformed, which further affects the clinical use effect.
[0008] 4. The original filler handle is too long and cannot better find the point of application.
[0009] 5. The working end is not bendable.
[0010] The method of delivering a small cotton ball to press the material is easy to leave the cotton ball in the root apex, which affects the effect of the root apex barrier, and more seriously, the root apex surgery may be the only way to remove it later.
[0011] The method of pressing material with a dental applicator stick can achieve iRoot BP Plus apex barrier surgery for anterior teeth with a large root apex hole in combination with the apex barrier filler, but it cannot achieve the effect for posterior teeth with a thin and long root apex, thereby affecting the success rate of the technology. INVENTION CONTENTS
[0012] The utility model aims at providing a kind of iRoot BP Plus is used to fill in the root tip barrier, improve the success rate of root tip barrier surgery, reduce the operation time of doctor, prevent patient operation time is too long and lead to joint restriction, improve the service life of young permanent tooth.
[0013] In order to realize the above-mentioned application purposes, the technical scheme of the utility model is as follows:
[0014] A kind of iRoot BP Plus is used to fill in the root tip barrier, including handle and filling rod, filling rod includes connecting end, working end and stick body, connecting end is detachably connected with handle, filling rod is the nickel-titanium alloy material of arbitrary bending shaping, working end is provided with T-shaped opening, the T-shaped opening is detachably connected with the expanded sponge ball;Gap exists between the bottom of T-shaped opening and expanded sponge ball.
[0015] The stick body length of the filling rod is 25-31mm;Expanded sponge ball size is 0.5-1.5mm.
[0016] The stick body of the filling rod is provided with a plurality of annular scale lines, and the annular scale lines are arranged at intervals.
[0017] The handle is of metal material, and the connecting end of the handle and the filling rod are detachably connected by threads.
[0018] Anti-skid lines are arranged on the handle, a circular hole is arranged at the top of the handle, a dental floss can be inserted through the circular hole, to prevent the dental floss from slipping out of the root canal and causing medical accidents such as mis-swallowing or mis-sucking.
[0019] The outer layer material of the expanded sponge ball is a medical-grade soft material, and the inner layer is a collagen sponge material;The outer layer completely wraps the inner layer;The medical-grade soft material ensures that the internal structure of the tooth is not damaged during operation;The outer layer completely wraps the inner layer.
[0020] The utility model has the beneficial effects that:
[0021] 1. In the utility model, the bottom of the filling rod is designed in the shape of an expanded small ball, which can better adapt to the narrow space of the root tip area, simulate the circular or oval shape of the root tip hole, and the small ball part design has a larger contact range than the traditional metal filler, so that it can better act on the tip of the root canal end. The small ball shape can concentrate the pressure, so that the iRoot BP Plus material can achieve more uniform and denser filling in the root tip area. In addition, the small ball shape provides a larger contact surface, ensures the full contact and adhesion of the material, avoids the occurrence of gaps or insufficient material, and achieves better sealing effect of the root tip.
[0022] 2. The sponge ball in the utility model can be bonded with the working end through buckle design, the bonding mode ensures that the sponge part will not fall off or move during operation, while maintaining a certain flexibility, so that it can deform with the movement of the working end, thereby adapting to the operation requirements of different angles. This connection mode not only ensures the stability of the sponge part, but also enables it to flexibly cooperate with the operation of the working end in the apical region.
[0023] 3. In the utility model, the sponge ball is soft and elastic, so that it can fully adhere to the inner wall of the root canal when entering the apical region, and fill the small gap. The sponge material can adapt to the complex anatomical structure of the apical region after being compressed, ensuring that the filling material can be evenly distributed in every corner of the root canal. At the same time, the sponge can absorb excess filling material to prevent overfilling, thereby improving the accuracy and safety of the operation.
[0024] 4. In the utility model, the T-shaped opening acting on the sponge ball has both downward force and lateral force, which can make the force of the sponge ball more uniform. When the filling material is compressed into the apical region, the material will be more evenly distributed in the root canal when subjected to pressure, and will not damage the structure of the apical region due to excessive local pressure; the filling rod and the sponge ball can better fit the inner wall of the root canal of different shapes, improving the flexibility and adaptability of the operation; improving the safety of the operation, which helps to prevent the occurrence of apical region damage or complications caused by material overfilling or excessive pressure.
