拔牙钳的数种分类

Share:

拔牙钳顾名思义就是用来进行拔牙的器械,它是拔牙器械中对牙槽骨的损伤最小的,是在拔牙术中通常都会用到拔牙钳。

钳柄、关节及钳喙是拔牙钳三个主要组成部分。钳喙是主要工作端,是牙钳夹持牙体的部分。操作者握住的部分叫做钳柄,有四种形状:直角型、直线型、刺枪形和反角形,不同形状的拔牙钳各有不同的用法。

大多数拔牙钳钳喙都是对称型的,不对称的只有上颌磨牙钳因牙根分叉位置不同而采用不对称设计。

一套牙钳最少应由9把牙钳组成,分别是:下颌前磨牙钳、上颌前牙钳、上颌前磨牙钳、左上颌磨牙钳、上颌根尖钳、右上颌磨牙钳、下颌前牙钳、下颌磨牙钳、下颌根尖钳。

 

一、上颌前牙钳又根据口内解剖部分分类为:

1、上颌牙钳2、下颌牙钳3、左右拔牙钳

 

二、根据拔牙钳用途分类:

1、下颌前牙钳2、上颌第三磨牙钳3、上颌前牙钳4、下颌第三磨牙钳5、下颌双尖牙钳 6、牛角钳7、上颌根尖8、上颌磨牙钳9、下颌磨牙钳10、上颌双尖牙钳

从拔牙钳分类的名字,我们就可以知道它们究竟是作用于牙齿哪部分的手术。

大人和小孩的拔牙钳大小也不相同,小孩子因为会动,所以用的拔牙钳会比较大,不会因为孩子的乱动而锁定不了目标牙齿,大人的拔牙钳相对就会小,因为大人不会乱动,很容易就能钳住目标。

拔牙钳使用的注意事项:

1、用力适当,摇动、扭动和牵引相结合。

2、 根据牙齿的形态,尽量选择能够牢固夹持的牙钳。

3、牙钳应正确安置于牙颈部,勿伤及邻。

4、根据拔除牙位的不同,正确选用牙。

拔牙钳的正确握持方法:主要以右手使用,右手的大拇指放在牙钳关节处,虎口部贴紧钳柄,要使拔牙钳能开闭自如,食指及中指握紧对侧钳柄外侧而环指及小指置于其内。在夹牢牙体后,将环指及小指置于对侧钳柄外侧协助示、中二指形成合力握紧牙钳。

If you are also planning to get a flow meter for your industry, then, first of all, you should know about the different types of flow meters. Here we have shared the details about different types of flow meters based on different parameters.

Mass Flow Meters

As you can see in the name itself, that these are mass flow meters, which means they will be helpful in measuring the mass flow per unit of time. In the industries where the processes include the mass and not the volume, these types of flow meters are used. Some of the industries where these mass flow meters are used are power industry, pharma industry, mining industry, and many such other industries. Mostly people prefer to buy Coriolis mass meters.

Velocity Flow Meters

We have just read above about the mass flow meters which were basically used for mass flow rate measuring. The velocity flow meter is for calculating the volumetric flow rate. You will find different types of velocity flow meters like the electromagnetic flow meters, ultrasonic flow meters, and many such other flow meters.

Open Channel Flow Meters

The open channel flow meters are usually big, and dam shaped. They are mostly used in calculating the flow rate of flowing liquids. And that is why they are generally used for rivers, streams, sewer, irrigation channels, and other flowing liquids. One can take or calculate the reading of the flow rate with the help of these open channel flow meters.

Final words

These are some of the common flow meters which we have mentioned above, that can be used for different purposes. Other than these flow meters, there are few more like Differential Pressure Flow Meters, Positive Displacement Flow Meters, and many others. These flow meters vary in shapes and sizes, and the kind of materials they are used to measure.

The Best of Roller Bearings for Your Choice

Share:

The bearings are used to ensure smooth and efficient operation on machines with rotary motion. They are effective, therefore, for various applications such as automobile wheels, engines and turbines or medical equipment.

A ball bearing is a type of bearing with rolling elements that fulfills three main functions, besides facilitating the movement: it resists loads, reduces friction and allows the positioning of the moving parts of the machine.

The roller bearing are composed of rolling spheres, separated by two “tracks” or bearing rings, which serve to reduce the contact surface and friction in the moving planes. The rotation of the balls reduces the coefficient of friction when the flat surfaces rub against each other. As the contact surface between the balls and the raceways is relatively small, the ball bearings have, in view of their size, a lower load capacity than other rolling element bearings.

What Are The Different Types Of Ball Bearings And Their Applications?
Ball bearings come in a variety of shapes and can be used in multiple applications. The choice of a type of ball bearing depends on the industrial application for which it will be used, as well as the load to which it will be exposed.

The most common models are:

Angular contact bearings: designed to withstand radial and axial loads.

Axial bearings: Also called thrust bearings or thrust bearings, are designed to withstand forces applied parallel to the bearing shaft or to axial loads.
Deep groove ball bearings: ideal for supporting radial loads and low axial loads.

Linear bearings: also called linear guides, allow movement in one direction along a linear axis.

Self-aligning ball bearings: also known as spherical ball bearings or spherical roller bearings, are bearings with two sets of balls that are automatically aligned and support radial loads and low axial loads.

High speed angular contact ball bearings: another variety of high precision ball bearings. As the name implies, these high-speed bearings have been specifically developed to adapt to high-speed applications with high accuracy.

What Are The Sizes, Shapes And Materials Of The Most Used Ball Bearings?
The sizes of ball bearings vary according to their use. The thickness of the bearing also depends on the application. For example, thin-walled bearings are particularly suitable for applications where space is limited. The difference between the diameter of the raceways (inner or outer) and the thickness is minimized, which allows for compact designs.

The materials used in ball bearings depend on their application. The vast majority of ball bearings are made of steel. Other bearings can be made of stainless steel to provide better corrosion resistance. There are also hybrid ball bearings, in these cases the raceway of the inner and outer rings are filled with ceramic balls to achieve high speeds of rotation.

For many explanations in the field of appliance construction https://www.synbearings.com/roller-bearing/, the constructive and dimensional types of standardized bearings cannot be used due to the reduced space available for the bearing or the special technical conditions. Thus new types of bearings with a more limited use are created, non-standardized bearings that are also subject to a typing and normalization process along with the quantitative increase in production. A classification of non-standard bearings can be made in relation to working speed, namely low-speed bearings and high-speed bearings.
