Dental Delivery Unit

Everything There Is to Know About a Dental Delivery Unit

According to medical dictionaries, a dental delivery unit is a fixed or mobile type of equipment, that includes engine, lamps, chair, instrumental table, and other parts that are somehow necessary while performing various examinations and treatment. Sometimes, these devices may also be called dental chairs or armchairs.

Creating a complete kit includes a complete set of all necessary equipment parts in one piece. This standardized and revolutionized device is made much cheaper by the manufacturing process. It helps medical practitioners to form general criteria of treatment and diagnostic procedures of all types. 

In a narrower sense, a dental delivery unit may also mean a fixating system for different drill machines, water pumps, x-ray devices, sterilization units, saliva aspirators, and more. This instrument finds its use in a vast number of cure and indicative processes in dentistry.

The history of a dental delivery unit

The history of these equipment parts is still very fresh, as they began to show up only with different modern models of the dentist's working place unit. It is hard to pinpoint the inventor of the exact part of the whole armchair, as there are lots of different inventions summarized in one. 

However, we can name the inventor of the ancestor of the central concept of the modern dental chair. John Naughton, a physician and dentist from Iowa, showed his device in 1958, which was fully stainless steel, with almost all principal parts of the modern full dentist's kit. 

Indications to Use Those Devices

Without those tools, whether we speak about a whole unit or only its instruments holder part, we would not get any single diagnostic or treatment procedure in the entire dentistry. Two main types of those devices exist nowadays - portable and static. According to a few studies, the portable ones may have a significantly increased yield in productivity to the static. They both are helpful during the following procedures:

  • General check-ups
  • Diagnostic procedures of all kind
  • Reparative dentistry
  • Dental cosmetical procedures
  • Maxillofacial surgery
  • Prosthetics of teeth and jaws

As this term may imply any part of the dentist's working place, they also include various instruments used in the intraoral treatment processes. For example, there is a tool called drill, which, when placed and held in the proper groove on the instrumental unit, can be useful for extracting damaged parts of the tooth tissues, polishing fillings, and drilling the bone in surgery. You can also find on those parts of equipment a water pump used for cooling teeth and instruments after drilling. All the components of that kit may be the source of bacterial contamination.

That delivery hub for every electric and air-powered instrument of the dentist may also contain in-built engines for uninterrupted power supply. In those cases, it may also be useful as a tool for various urgent neurosurgery, neck, eyes, and face operations.

Complications of Using a dental delivery unit

There are lots of complications connected with the use of these tools. The significant majority of those apparatuses are non-specific. The complications fall in the following subdivided groups:

  • Connected with bacterial invasions
  • Occurs due to a malfunction of the apparatus
  • Emerge due to doctoral mistakes

The first group of complications occurred when hygienic and aseptic rules are not followed. For example, when the same instrument is using for examination or curing of different patients without intermediate processing, the possible bacterial contamination may occur in various ways. It mostly occurs through the surface of non-sterile equipment parts, including any part of apparatuses of that type.

Talking about the second and the third group, they mostly lead to the same type of injury, primarily different traumas. For example, when any malfunction of the drill machine occurs, there is a vast possibility of traumatizing the oral cavity's soft and hard tissues. The same types of various complications arise if a doctor misuses an instrument or uses it without proper attention and caution.

General Specifications of a dental delivery unit

As there are numerous chair-like tools and single parts intended only for the various instruments' delivery, it was hard to determine and show the general specifications of those apparatuses. So, we decided to pick up the most common type of them and analyze models available on the contemporary market. Here are the specs for portable tool:

  • Touchpad - optional
  • Foot control - button or lever-style
  • Left-right conversion - optional
  • Holder positions - 5+ positions
  • Handpiece turbine - silicone covered
  • Light and observation source - dental lamp, intraoral camera or scanner
  • Arm system - with air brake
  • Mount option - optional
  • Brake handless - N/A
  • Water system - 2 L bottle
  • Integration - 4,5 m cable 2,0 USB, 4+ control modules
  • Battery - included

More information about the classification, requirements, suitable materials, possible parts, and normative references is on the ISO 7494 - 1. That document is verified with a complete reappraisal every few years. The most relevant revision showed up in the 2018 year. To use this document for a manufacturer's purpose, you should put it on the official website.

How They Work

Most commonly, these apparatuses have various engines and electric parts that require electricity. Usually, their power is from the central electrical network. However, most portable models supply batteries, making it possible to use, even in field conditions.

Doctors pick up the instruments from that piece of equipment and put them back inside the unique grooves when they need to use some different parts of the dentist's supplies. Usually, all the tools from apparatuses of that type are launched-up with a footswitch, buttons, or touchpads. The whole sections of the device need a general check-up before the start of the examination or treatment of every new patient.

Market Leaders

Lots of different companies sell this equipment worldwide, and every day some new models show up. That is the main reason that this list is very temporary. However, the current TOP five positions wouldn't lose their actuality in the next few years. Here are the market leaders among the manufacturers of dental delivery units:

  • NSK
  • TS Dental
  • Planmeca
  • A Dec
  • Ultra Dent
  • Meunier Carus
  • Airel Quetin
  • BPR Swiss
  • Fimet
  • Tenko Medical
  • Navadha

There are lots of inexpensive, but, unfortunately, short-lived models of these tools from various Chinese and Indian manufacturers available nowadays on the market. In some cases, they may create possibilities for different dental traumatic situations occurrence.

Conclusions

Dental delivery units are valuable tools that find their use nowadays not only in different dentistry spheres but also in neurosurgery, ophthalmology, and maxillofacial surgery. Nowadays, there are lots of different models available on the market for both portable and fixed devices. Probably there are still various modifications to add to the construction set of these apparatuses, which makes them even more useful and comfortable for both patients and doctors. For example, by making a few additional engineering improvements, these tools can easily replace the surgical instrumental tables, C-arm X-ray apparatuses, and even autoclaves.
