dental drills are accompanied by dental drill bits. These bits are used for various applications in the mouth. These different types of bits are meant to cater to their work in one way or the other. The types include:
Burs
Dental burs are mainly steel or tungsten carbide. Carbide burs are defined as the most popular bite size and shape to cut, drill, and grind material in the dental industry. When it comes to burs, the larger the head size, the more the cut depth. On the other hand, smaller burs are meant for fine cuts. For example, bur 330 is an eyetooth excavator that makes large holes. At the same time, bur 557 is a fissure bur, which makes small enamels except between the teeth.
Crown cutting burs
Crown cutting burs, like crown remover dental tools, are used to cut the crowns and any bridge that may need to be removed. When dealing with restorative materials like resin, amalgam, and ceramic, a dental drill such as the crown cutting bur with a diamond paste is preferred. For example, a diamond fissure bur is used in cutting porcelain and other ceramic materials.
Polishing burs
For polishing teeth or dentures, polishing burs are used. They are made with a tight rubber bonded composition. Polishing burs are then mounted on an electric motor. The major drawback of polishing bur is that it wears rapidly. Depending on whether the teeth are natural or artificial, polishing is also done using polishing paste for better finishes.
Stone burs
Stone burs are preferred for their longevity, especially when dealing with hard materials. The stone is extremely hard and durable. Stone burs are ideal for cutting down porcelain or ceramic crowns. Stone abrasives are mainly designed to give a polishing effect on materials and are suited for cutting or grinding purposes. An example includes aluminum oxide, which is used in polishing aluminum and ceramic surfaces.
Cavity preparation burs
Cavity preparation burs are primarily used to prepare teeth for fillings. Burs such as the 330 caries excavator are used in removing decayed material when making an intraoseous mandibular nerve block. Slow-speed 56 and 57 burs are meant for removing soft dentin. Stronger burs like 62M and 63M are intended for removing hard dentin. Green Stone is ideal for cavity preparation due to its hardness.
Dental tools like dental suction can be applied to many industrial applications apart from the obvious medical field. Those applications include the following:
Manufacturing
Precision tools such as dental drill bits are widely used in creating products that require precision. Things like mechanical parts, electronics, and aerospace components. With their ability to create fine details and accurate holes, drill bits are essential in producing parts like gear, motor, and aircraft components.
Automotive industry
The automotive industry employs dental drill bits in several assembly and repair processes. For example, they are used in drilling or fastening the internal engine components. In this case, the bits come in handy in precision tasks such as headlamps, dashboard, and tires.
Electronics
As mentioned earlier, these drill bits are essential in PCB production. They help create holes for plating and component installation. Further, they're also used in assembling electronic devices like smartphones, computers, and other gadgets where precision is a necessity.
Aerospace
As in mechanics, these bits are used in making and fixing components of aircraft. Precision drill bits ensure the structures are efficiently fastened, which is crucial for performance and safety. They also help create internal engine parts and devices to ensure minimal resistance.
Jewelry making
In jewelry making, drill bits are employed in creating intricate designs, especially in precious-metal products. For detailed drilling on gold, silver, and platinum, dental drill bits will perform this task perfectly. They help in designing finer drill holes for stone setting or creating patterns and designs.
Optics
To manufacture high-precision items like lenses, optical instruments, and binoculars, drill bits are used. They are needed to carefully and accurately assemble the optical components.
Agriculture
Certain precision farming implements also utilize drill bits. For example, the bits can be used in making holes in seeders or planters, thus enhancing effective planting. Dental drill bits can also drill through soil and rocks.
Material
The material of dental drill bits determines their usage and performance. Steel bits are a cost-effective option for general use. Tungsten carbide bits retain their sharpness for long use. Diamond burs are the most durable and efficient for cutting hard substances. Ceramics crowns, however, require a porcelain bur and a porcelaine crown.
Shape
The shape of a dental drill bit also affects the results. Round bits are used for hollowing out an area. Fissure bits are ideal for cutting lines or fissures. The end tapering of cylindrical bits helps in parallel drilling.
Finishing
The finishing used on the dental drill bits plays a crucial role in how the bit interacts with the tissue. Bits that are fine and polished enamel reduce the amount of force required for cutting.
Compatibility
Compatibility between handpieces and burs is essential to ensure efficiency. High-speed burs are used with the handpiece to generate lots of speeds and are ideal for cutting. Low-speed burs are mostly used in cavity preparations and other general dentistry tasks.
Application
Choosing a drill bit largely depends on its intended use. Restorative dental burs are used to cut intermediate materials like amalgam and resin. The diamond burs are ideal in cutting uniformly for porcelain and ceramics and are thus used in crowns and bridges. For cavity preparation, carbide burs, like 330 and 557, are used.
Storage
How the dental drill bits are stored determines their longevity. Bur cases with individual slots are recommended for storage. In this case, the bits are stored in an orderly manner so that none is lost or misplaced. Avoid storage with other hand tools that may cause damage to the bits.
Rotation
Rotation is how many times an object will rotate around a fixed point. The rotational speed of a drill also affects the dentist's task. The low-speed burs are used with handpieces that generate less speed and are suitable for pedodontics or conservative dentistry.
Into the dental drill is a drill bit that works internally, and as such, no pain is felt. For sensitive teeth, local anesthetics can be administered for better comfort.
Since dental drills are made of materials like tungsten and carbide, they can easily cut into tissues. However, they are designed to withstand tissue recognition, and with a variety of burs like zirconia, which is smooth finished and pure cutting. Also, as long as cooling is practiced, there won't be any harm.
Drilling is crucial in dentistry because it helps remove decay, shape the cavity, and smooth the surface. Besides, this procedure is fast, painless, and accurately performed. Most importantly, drilling is done for restorations, root canals, crowning, veneers, and implants.
Dental drills can work without electric handpieces. Mechanical handpieces are used in the past, but due to electrical inventions, people now like it better. That said, for people who hate noise during drilling, mechanical handpieces are the best alternative.
Dental burs that are used to drill for fillings include 330 burs for cutting, 557, and fissure burs for confined space. For posterior teeth, 63M and 62M are used to cut hard dentin materials.
Diamond burs are expensive but worth it. No other materials can match its efficacy. It can be utilized in metal crowns like gold and silver, porcelain, and ceramic. It's finely and evenly manufactured with a long life.
