Collagen fibers get organized in a stable keratinized tissue.
Implant surfaces not only are the substrate with which the biological structures interact after the insertion of the fixture, but also activate the signals that cause a different response in terms of proliferation and cellular organization. This concept, very discussed in the literature  as regards hard tissues, is now considered important also for soft tissues. 
Specifically, a study of the National Institute of Dental and Craniofacial Research has drawn attention to new cellular migration concepts with a new technology called µPP capable of taking photographs of micropatterns of surfaces and the cellular behavior on them. SEM microphotographs prove that cellular migration appears to be unidirectional and independent from the density of the extracellular matrix, but quite dependent on the characteristics of the substrate.

The grooved surface, with a unidimensional pattern, seems to be the best condition to facilitate cellular mobility and phenotype expression.

With these premises, Sweden & Martina has developed the UTM (Ultrathin Threaded Microsurface) treatment: a microthred that runs all along the neck of the Prama implant offering a guide to the fibroblasts unidirectional movement for all the length of the transgingival portion.
