3 reasons why Charisma Diamond with its unique TCD matrix can be your game changer
Today's dentists face a myriad of challenges: demanding patients, the need for durable and long-lasting results, and the expectation of restorations that look natural and aesthetically pleasing. The good news is that using the right materials can make your daily challenges much easier. One such innovative solution is Charisma Diamond, powered by Kulzer's unique TCD matrix, a breakthrough in dental composite technology
1. High flexural strength combined with minimal shrinkage stress
First and foremost, the value of durable dental materials cannot be overstated. Patients expect and deserve restorations that stand the test of time, minimizing the need for repeat visits and additional treatments. Charisma Diamond, based on Kulzer's Tricyclodecane (TCD) matrix, is specifically designed for durability, with a high degree of cross-linking that provides exceptional mechanical strength. This robust structure helps to reduce the likelihood of chipping and fracture, one of the main reasons for restoration failure.
This advanced structure of the TCD matrix helps to make restorations less prone to chipping and fracture, giving dentists greater confidence in their work and patients long-lasting results.

2. Reduced shrinkage stress
During the light-curing of composites, shrinkage stress is a common problem that can lead to marginal gaps and consequently secondary caries. Charisma Diamond addresses this issue with its low shrinkage stress, thanks to the TCD matrix and optimized filler system.
Dr Andreas Utterodt, Senior Scientist at Kulzer, explains: “The unique feature of TCD is the urethane molecule, which vibrates less and takes up less space than conventional matrix molecules. This minimal movement results in significant benefits such as low shrinkage stress, which helps to reduce the risk of marginal gap formation and secondary caries.”

Conclusion: Not all low-shrinkage composites in this test demonstrate low polymerization shrinkage values. Also in order to effectively reduce polymerization stress, a low post-gel shrinkage must be associated to a relatively low elastic modulus.
3. The TCD-matrix is free of BPA-related monomers
In today's dental environment, patients are increasingly concerned about the composition of the materials used in their treatment. Charisma Diamond is formulated without any BPA-related monomers. Investigations conducted by an external analytical laboratory found no detectable BPA release from Charisma Diamond composite (test reports 10-2023 and 03-2025). This provides additional assurance of the safety and reliability of these materials. BPA Statement
Enhance your practice with Charisma Diamond and its unique TCD matrix
In summary, Charisma Diamond offers a comprehensive solution to today's dental challenges by improving durability, reducing shrinkage stress, ensuring patient satisfaction and achieving aesthetic excellence. Incorporating Charisma Diamond into your practice can lead to more efficient procedures, improved patient outcomes and higher levels of satisfaction for both dentists and patients.
