The design of the primary telescopics is an important step that requires special attention. It is of the utmost importance to avoid sharp edges, as these not only pose a risk to safety, but can also impair the accuracy of fit and functionality of the telescopic. Instead, we recommend opting for rounded edges. These are not only safer to handle, but also facilitate the internal fit, which contributes to improved functionality and longevity of the telescopic. This recommendation is based on our many years of experience and our desire to offer you, our customers, the best possible expertise and practical solutions. Our tips are designed to support you in your professional work and ensure that the telescopics you create meet the highest quality standards.

Tip: When designing the primary telescopics, choose rounded edges to optimize safety, accuracy of fit and functionality.


Reason: The design of the primary telescopics with rounded edges is a decisive factor for effective and precise milling. These rounded edges are important to calculate the milling correction. During the milling process, rounded edges enable more efficient machining, as milling instruments work better on surfaces than on corners. Angular edges or sharp corners can be more difficult to machine, as the milling instruments do not work optimally in such areas. In addition, rounded edges prevent the formation of cavities which could occur during a milling correction. Such cavities can impair the structure and stability of the telescopic and therefore have a negative impact on the accuracy of fit and functionality. The integration of rounded edges into the design of the primary telescopics ensures optimum adaptation and long-term reliability of the telescopics, which is crucial for the quality of your dental work.

In addition to the careful design of the primary telescopics, the choice of insertion directions for secondary telescopics also plays a decisive role in ensuring precision.

In the precise world of dental technology, attention to the smallest details is of crucial importance. A key element here is the choice of insertion directions for secondary telescopics. Each primary part has its own specific characteristics, and to ensure an optimal fit, it is essential to choose an individual insertion direction for each of these parts. This makes it possible to effectively compensate for small divergences and achieve perfect harmony between the telescopics.

Tip: Adjust the insertion directions for each secondary telescopic individually to ensure optimum fit and function.

Reason: Each primary part of a telescopic has its own specific characteristics and dimensions. An individual adjustment of the insertion direction for each secondary telescopic is therefore necessary to compensate for small deviations or divergences that may occur during the production of the primary parts. This precise approach allows each secondary part to fit exactly and without tension on the corresponding primary part. Such a customized fit not only ensures perfect harmony between the telescopics, but also helps to increase the longevity and functionality of the prosthesis. The individual adjustment of the insertion directions ensures that the telescopics slide into each other without unnecessary pressure or friction, which increases wearing comfort for the patient while minimizing the risk of damage or premature wear of the telescopic components.

Such customization is not only a sign of craftsmanship, but also reflects a deep understanding of the complexity and intricacies of telescopic technology. With this technology in particular, it is important to keep an eye on every detail. Paying attention to this point ensures that the telescopics you produce are not only functional, but also comfortable for use in the dental practice.

Following the consideration of the insertion directions, we will now focus on another critical area: the internal fit and the blocking out of the undercuts.

Another crucial aspect in telescopic technology is the careful design of the internal fit. A key element in this process is the blocking out of undercuts. This is often the most effective way to ensure an optimal fit and function of the telescopics.

Blocking out the undercuts creates an even and frictionless surface which contributes significantly to the overall stability and comfort of the telescopic prosthesis. This method minimizes the risk of stresses and inconsistencies between the parts, ultimately resulting in a more accurate fit and preventing future complications. It is a process which requires not only technical know-how, but also a deeper understanding of the material dynamics and interactions within the telescopics.

Tip: Use the blocking out of undercuts to optimize the internal fit of the telescopics and achieve a higher accuracy of fit.

Reason: Blocking out undercuts is an essential process in the fabrication of telescopic prostheses, especially in the context of the preparation margin, which usually has a chamfer. The aim is to make the edge of the prosthesis as long as possible, whereby it should be noted that there may be a downward bend. This makes the blocking out of undercuts all the more important in order to ensure an even and smooth surface and the optimal fit and function of the telescopics.

Experienced dental technicians have mastered tricks which enable them to deliberately switch off the block-out function. This is an advanced procedure, as deliberately maintaining undercuts requires a deep understanding of the material dynamics and the interactions within the telescopics. However, deliberately switching off the block-out function is not recommended for beginners in dental technology, as it can lead to problems with accuracy of fit and functionality without extensive knowledge and experience.

Having emphasized the importance of blocking out undercuts, we would now like to address an essential point: the effective handling of friction points.

One of the challenges is dealing with friction points that can occur during the fitting process of telescopics. It is essential to identify these friction points at an early stage and handle them accordingly.

If friction points become visible when fitting telescopics, it is advisable not to start the grinding process directly at the affected point, but above it. This approach helps to remove the material evenly and thus avoid a sticking effect. Such gentle and gradual processing not only ensures a more precise fit, but also protects the structural nature of the telescopic components.

Tip: Start the grinding process above friction points to ensure even material removal and avoid jamming effects.


Reason: Starting the grinding process above the friction point ensures that the material is removed evenly and in a controlled manner. This approach makes it possible to reach and process the friction point precisely without excessive removal or damage to the surrounding material. Such a gentle and gradual approach is crucial to maintaining the precise fit and functionality of the telescopics. It helps to prolong the life of the prosthesis and ensures comfortable and problem-free use by the patient. This technique not only protects the structural integrity of the telescopic components, but also ensures a more consistent and satisfying wearing experience for end users.
