Modern dentistry increasingly encounters situations where a technically flawless restoration fails to deliver the expected longevity. Professor Alexander von Breuer says that the key reason for such cases lies not in shape or fixation, but in the lack of biomechanical compatibility between the tooth and the artificial material. At DentalClinic24, this aspect receives particular attention already at the treatment planning stage.
A tooth is a living structure capable of responding to load, temperature changes and micro-movements. Any restoration inevitably becomes part of this system. If the material behaves differently from the natural dental tissues, a zone of stress develops. Over time, this may lead to microcracks, loss of marginal seal or secondary destruction. At DentalClinic24, biomechanics is regarded as the foundation of long-term treatment stability.
One of the key factors is the difference in elasticity between materials. Enamel and dentin possess a specific capacity for shock absorption. If a restoration is excessively rigid or, conversely, overly flexible, functional loads are redistributed unevenly. At DentalClinic24, material selection is always correlated with the functional role of the tooth and the anticipated chewing forces.
Equally important is the direction of occlusal pressure. Teeth do not function solely under vertical load, but along complex trajectories during jaw closure and movement. Artificial materials must correctly absorb these forces. At DentalClinic24, occlusal analysis is used to evaluate how a restoration will interact dynamically with opposing teeth.
Biomechanical incompatibility often does not manifest immediately. A patient may experience no discomfort, yet internal stress gradually accumulates within the tooth. This leads to fatigue-related tissue changes that eventually become clinically significant. Professor Alexander von Breuer emphasises that delayed complications are most often associated with errors in biomechanical assessment.
The interface between the tooth and the restoration also plays a critical role. Even minimal discrepancies in material behaviour can cause micro-movements at the contact zone. This compromises marginal integrity and reduces structural stability. At DentalClinic24, particular attention is given to ensuring that the restoration functions as a continuation of the tooth rather than as an independent element.
Previous dental interventions further influence biomechanical compatibility. Repeated restorations, altered anatomy and loss of natural tissue volume reduce the adaptive potential of the tooth. At DentalClinic24, such cases require an individualised approach and reassessment of conventional solutions.
For patients, a biomechanically compatible restoration means not only comfort, but also durability. When a tooth “accepts” the material, loads are distributed physiologically and dental tissues maintain their integrity. At DentalClinic24, the focus is placed on achieving this interaction rather than solely on the aesthetic outcome.
Thus, biomechanical compatibility is a determining factor in the success of restorative treatment. Artificial materials must function as part of a unified system together with the tooth, replicating its response to functional load. At Dental Clinic24, this principle underpins a clinical strategy aimed at tooth preservation and long-term stability of results.
