Dental microscopes

How to choose a dental microscope

Choosing a microscope for dentistry, also known as a dental microscope, involves two areas: the installation conditions in the practice and a configuration suited to the clinician’s way of working.

Space in the practice, installation and suspension system

The floor area and layout of the practice, together with the arrangement of the treatment workstation, influence the choice of installation. Depending on the model and configuration, this may be a mobile system, wall or ceiling mounting, or integration with the treatment workstation. Compact dental microscopes are easier to accommodate in smaller rooms. Where the practice offers greater freedom of layout, more extensive microsurgical microscopes can also be considered. This broadens the choice of suspension systems and equipment configurations.

Optics, ergonomics and equipment suited to the operator

The second area is matching the optics, ergonomics and equipment to the operator’s needs. Relevant elements include the suspension system, light source, operator’s binocular tube, magnification range, working distance, controls, video system and additional equipment. Their selection should reflect the types of procedures performed, the clinician’s working habits and image recording needs. Since the same model can have different configurations, the equipment of the individual unit should be compared. Every microscope available from Medical Elektro has its own photographs and a technical description relating to that particular unit.

During a procedure, the operator usually moves from lower magnification, which makes it easier to orient themselves in the field, to higher magnification for assessing fine details. Increasing magnification usually narrows the field of view and reduces the depth of field, and may also affect image brightness. The maximum magnification alone therefore does not describe the quality of observation. In dentistry, illumination directed as close as possible to the observation axis and a clear image in the mirror are also particularly relevant, especially in areas that are difficult to access.

Dental microscopes and microsurgical microscopes

The choice of equipment need not be limited to models designed with dentistry in mind. This group includes ZEISS OPMI Pico, ZEISS OPMI PROergo, ZEISS EXTARO 300, Leica M320 and microscopes from the CJ-Optik Flexion family. These systems are adapted to use in the dental practice and are available with different installation options and equipment configurations.

The second group consists of selected microsurgical microscopes that can also be used in dentistry when suitably configured. Examples include ZEISS OPMI Vario, ZEISS OPMI Sensera, ZEISS OPMI Pro Magis and Leica M525. Depending on the model, they may offer more extensive suspension systems, in which electromagnetic brakes often assist microscope positioning, as well as motorized functions, a wider adjustment range and additional configuration options. Each unit should nevertheless be assessed individually in relation to the available space and the operator’s way of working.

A comparison of ZEISS OPMI Pico and ZEISS OPMI Vario illustrates the differences between these two groups.

This comparison does not mean that either model will be suitable for every practice. It does show how great the difference can be between a compact dental microscope and a more extensive microsurgical system.

In practice, OPMI Pico in its highest equipment configuration can be more expensive than a single-operator OPMI Vario available on the used equipment market. The price nevertheless depends on the individual unit’s configuration, so the comparison should concern the actual equipment rather than model names alone.

When comparing configurations, it is also worth considering the orange filter for working with light-curing materials. In OPMI Pico, it prevents the premature curing of composite fillings under microscope illumination. In procedures that do not use such materials — including some dental and maxillofacial surgery procedures — the absence of this filter does not prevent the use of a suitably configured microsurgical microscope.

Microscope applications in dentistry

Microscope use in dentistry is not limited to a single specialty. Magnification and appropriately directed illumination improve visibility of the directly observed working field, helping the clinician monitor fine structures, preparation margins and the work being performed. The choice of binocular tube, working distance and method of positioning the microscope also affects operator ergonomics.

Endodontics is the area most commonly associated with microscope use. During initial root canal treatment, magnification and light directed into the pulp chamber help assess its floor, locate root canal orifices and observe the accessible anatomy. During root canal retreatment, the microscope helps the clinician monitor the field when removing material from the chamber, root canal posts or selected obstructions, and when searching for previously missed orifices. The image only shows structures accessible directly or in the mirror, however, so it does not replace radiological diagnostics or other methods of monitoring treatment.

Endodontic microsurgery is a separate area in which the microscope supports observation of the exposed root apex, assessment of the surface after root-end resection, identification of root canal isthmuses, and monitoring of root-end preparation and root-end filling. At these stages, magnification is relevant alongside illumination directed into the surgical field, stable microscope positioning and the ability to work with microsurgical instruments and ultrasonic tips.

Beyond endodontics, a microscope can be used in conservative and adhesive dentistry to monitor preparation margins, the tooth surface and the tooth restoration being performed, and at selected stages of prosthodontics to assess visible details. In dental surgery, periodontics and implantology, it enables observation of tissues, wound edges and elements of the surgical field, and can support precise suturing. These are diverse areas, however, so conclusions about endodontic applications should not automatically be extended to dentistry as a whole.

If the microscope has a suitably configured video system, it can also be used to record the work being performed and show the image to the patient or assistant. The scope of use nevertheless depends on the procedures, the equipment configuration and the clinician’s way of working.

ZEISS, Leica and CJ-Optik microscopes in dentistry

ZEISS microscopes

The group of ZEISS microscopes designed with dentistry in mind includes OPMI Pico, OPMI PROergo and EXTARO 300. OPMI Pico is a compact, manually operated system, while OPMI PROergo offers a more extensive suspension system and motorized functions. EXTARO 300 is another system developed for dental work. The ZEISS portfolio thus includes equipment with different levels of automation, positioning methods and image recording capabilities. Suitably configured OPMI Vario, OPMI Sensera and OPMI Pro Magis form a separate group, bringing features of more extensive microsurgical systems into the dental practice.

Leica microscopes

Within the Leica microscope portfolio, Leica M320 has a prominent place in dentistry. The model can be configured with different mounting systems, binocular tubes and image recording solutions. A suitably configured Leica M525 can provide an alternative from the microsurgical systems group. In each case, the equipment of the individual configuration should be assessed.

CJ-Optik microscopes

CJ-Optik specializes in dental microscopes. The Flexion family includes models with stepwise magnification adjustment and systems with smooth zoom, as well as different illumination, filter, image recording and mounting options. Flexion Advanced Zoom and Flexion Twin illustrate two different approaches to configuration.

What affects the price of a dental microscope

The price of a dental microscope depends primarily on the model and version, type of suspension system, optical configuration, illumination system, video system and additional equipment. Differences may result from a simpler or more extensive suspension system, manual or motorized operation, the type of binocular tube and objective lens, the light source and image recording capabilities.

Additional components such as a camera, monitor and optical accessories also affect the cost. Two microscopes of the same model can therefore have different prices. A highly equipped compact model may cost more than the basic configuration of a more extensive system. A sound comparison requires examining the technical specification of the individual unit and assessing which equipment is actually needed in the practice.
