Rear, side, patient or head delivery… While manufacturers often boast the aesthetics and productivity characteristics of different delivery systems, there is little literature on the effects of each type on the musculoskeletal of dentists. Healthy, or impact on productivity. Each delivery system has advantages and disadvantages. Knowing them can help dentists choose the right Cheap China Dental Delivery Unit for their team.
The most commonly used handpieces should be placed closest to the assistant. However, it should be noted that handpieces do not actually exceed 15% of typical procedures, so their ergonomic placement is far less important than the entire treatment device.
The hoses on all delivery systems should be lightweight and flexible to avoid muscle strain. This is usually achieved by silica gel, low pressure, straight six needle or ISO-C tubes. Although fiber bundles have better light output, they also add weight and stiffness.
The posterior delivery system accommodates all clinical instruments behind the patient, freeing up space for large devices in operation. This is the cheapest way to connect to a utility and keep the device away from the patient, which reduces anxiety. Functionally, when implementing true four-handed dentistry, the rear delivery work is quite good (ie, the device is within the scope of the assistant, transferring the device, retrieving the phone and changing the burrs).
If placed correctly, the lateral delivery system requires less torso rotation for the surgeon than a posterior delivery to retrieve the instrument. However, because the assistant is unable to access the instrument, the dentist must remember to face the system while changing the burr, rather than maintaining a distorted posture.
Moreover, since dentists retrieve mobile phones and assistants cannot reach them, productivity is often compromised. Due to the high-tech, there are new concerns about by-products.
