Outcomes of direct restorations of the chewing group of teeth with and without optics.

Aesthetic dentistry does not stand still, and every year it develops with tremendous speed, manufacturers offer the latest materials that can improve the aesthetic effect of restorations and bring them closer to the original tooth tissues. One key element in carrying out restorations is the use of various auxiliary materials, one of which is the use of optics, to maximize the detail of the working field. Many specialists involved in direct restorations believe that optics is not a key success factor in dental restoration, whereas a deep understanding of dental anatomy and a high level of practical skills play a much more important role in the final result of the work. Other specialists, on the contrary, actively use optics in their work and believe that the use of optics makes it possible to achieve maximum aesthetic effect in restorations.
When performing aesthetic restorations under a microscope, the doctor first of all creates for himself the correct and comfortable ergonomics, which allows him not to be distracted and fully immerse himself in his work. The location of the microscope allows the doctor to take the correct position and fully control the patient's movements, thereby obtaining good visualization. Direct restoration under a microscope makes it possible to maximize the view of the working field by almost 90%, and high magnification eliminates peripheral interference for the doctor, and makes it possible to restore the primary and secondary anatomy as accurately as possible. The large magnification of the microscope makes it possible not only to achieve maximum aesthetic effect, but also to eliminate errors at all stages of preparing the tooth cavity for restoration. It is also necessary to take into account the auxiliary elements for the microscope, which will allow the doctor to carry out the restoration more accurately and without interference. Choosing the color of the cofferdam, using special modeling tools, and working as a four-handed assistant. Performing direct restoration under a ZUMAX OMS 3200 PRO surgical microscope at 5x magnification provides high detail of the working field and eliminates peripheral interference, the doctor is fully focused on working and restoring the anatomy of the tooth and preventing various errors during the restoration stages. The outcome of the restoration proves that the use of large magnification allows you to get as close as possible to the original anatomy of the tooth and restore its chewing and aesthetic function.
During restorations on the ZUMAX OMS 3200 PRO surgical microscope, special orange light filters are used, which ensure premature polymerization of the composite and preserve all the properties of the composite in its original form, which allows you to simulate the anatomy of a tooth without restrictions. The ergonomics and design of the microscope allows the doctor not to be distracted by extraneous tasks during treatment, which improves the quality of treatment several times. Changing the magnification will allow the doctor to more accurately understand the picture of the work, not only the position of the surgical field, but also to obtain a more accurate primary anatomy, eliminating errors at the modeling stages. When modeling the secondary anatomy of a tooth and anatomical features, the choice of 6x magnification on a microscope allows the doctor to restore anatomical features in detail and get the maximum aesthetic effect.
The use of binoculars in therapeutic dentistry has long been well established. Equipping binoculars with additional light has advanced the level of binoculars and increased their efficiency, as well as the range of applications in various directions. The use of binoculars in direct aesthetic restorations makes it possible to expand the surgical field and increase the level of restoration. The maximum magnification that binoculars can achieve is 4-5 times magnification, which allows for a fairly good detail of the surgical field. The use of binoculars forces the doctor and the patient to look for the right position, to arrange the optimal working length for the doctor for good visualization. A significant reduction in the allowable surgical field during restorations in binoculars is reduced to 15 cm. The reduction of the working field violates the ergonomics of the doctor, which entails making mistakes at various stages, and in the future will affect the outcome of aesthetic restorations. Working with Dr.Kim DKT-4 binoculars increases the level of direct restorations, the additional light that is built into the binoculars allows for a better assessment of all the additional nuances of the surgical field during restorations, which increases the level of modeling at the stages of primary and secondary anatomy.
One of the important problems when performing direct restorations in binoculars is choosing the correct position of the patient and the doctor. To obtain an optimal working field, it is necessary to constantly hold the initial position so as not to lose the initial magnification. Also, one of the problems of additional light on binoculars is its scattering of cold rays, which affect the premature polymerization of the composite. Changing special lenses or turning off additional lighting on binoculars disrupts the ergonomics of the doctor's work, the initial position of the doctor and the patient is lost, as a result, it is necessary to start searching for the working length to obtain the optimal working field. The additional cost of switching on or off confuses the doctor, which increases the risk of making mistakes at the stages of aesthetic restorations.
Direct dental restorations without additional augmentation are performed daily in the practice of therapeutic dentistry. The success of these procedures is determined by many factors. The key aspect is the doctor's ability to maintain concentration, ignoring external stimuli and peripheral interference. Focusing on recreating the primary anatomy of the tooth plays a crucial role in achieving a high-quality result. The secondary anatomy of the tooth and additional elements depend on the level of the specialist's manual skills, as well as on the visualization conditions and the availability of a workspace for modeling.
Currently, it is impossible to improve the quality of direct restorations without using magnifying tools. The result of the restoration is influenced by various factors, such as the doctor's manual skills, knowledge of the anatomy of the tooth and the conditions for modeling. These aspects are key to achieving a successful outcome of the procedure.
Conclusion. The use of optical devices in performing direct aesthetic restorations allows doctors to reach a new level of quality that they can offer their patients. However, there are significant efforts on the part of specialists behind this. Doctors who work with augmentation undergo additional training, regularly attend advanced training courses and learn new techniques. They use expensive tools and materials specifically designed for magnification, and also pay attention to creating an optimal working environment. Four-handed work with a qualified assistant helps to minimize distractions and fully concentrate on the task, which contributes to achieving the best aesthetic result.
