The importance of magnification in implant dentistry

By Dr Marcelo Oliveira

How reliable are your eyes?

Implant dentistry requires specific motor skills with an intense and focused vision for several hours consecutively. However, the conditions and obstacles that we usually encounter in the oral cavity can add a considerable burden to our vision and limit our ability to perform at our best. This is one of the main reasons why loupes are the standard of care in dentistry.

During the 30 years of my career as an oral surgeon, I have noticed that at times all I needed was a little rest to fully recover my vision and restore my posture. Over the years, that need for rest intervals became more frequent and longer. That’s when dental magnifying loupes helped me tremendously to become more efficient in my daily routine. I improved both my posture and vision, optimising my chair time.

What is eyestrain and how can it limit your practice?

Eyestrain is a common condition that occurs when your eyes get tired from intense use. In the oral cavity, operating sites are usually small and poorly illuminated. Under these conditions, the human eye can be deceptive when seeing fi ne important details leading to clinical errors that could have been foreseen when using magnifying loupes.

Struggling to see into the patient’s mouth with indirect vision can also cause:
• Sore neck, shoulders, or back from poor posture
• Burning or itching eyes
• Blurred or double vision
• Headaches
• Increased sensitivity to light
• Difficulty concentrating
• Feeling that you cannot keep your eyes open
• General increased fatigue

Eyestrain can be unpleasant and disruptive to our ability to focus and perform at our best. The symptoms of eye strain may lead to physical fatigue, decreased productivity, increased numbers of work errors, and anxiety.

How to minimise risk and exposure?

Increased magnification and improved illumination of the operating field have many benefits for the operator and directly reduces eye fatigue. An enlarged view of the operating site using proper vision enhancement tools will make your practice more precise, efficient, and enjoyable.

Direct light positioned in front of you into your operating field will maximise illumination while minimising reflective glare from the mirror and reducing shade in your field of view.

The ability to work with a high level of accuracy and improved control reduces treatment time and operator fatigue. Reducing the working time to execute implant procedures results in increased patient case acceptance and profitability for your practice.

Dental magnification and illumination: A breakdown of the most relevant products in implant dentistry

EyeZoom™ Variable magnification loupes: The first and only three-in-one variable magnification loupes, EyeZoom™ offers magnification levels ranging from 3x-5x. Developed for dental professionals who need a lower magnification during surgery
