Inteross® collagen block in alveola preservation

Introduction: The dentist always tries to save the patient's teeth, but sometimes this is not possible for various reasons. In most cases after teethextraction occurs one resorption of the alveolar process, thereby reducing its height and width. We do the preservation of the alveolus in order to preserve a sufficient volume of it.
Objective: The preservation of the alveoli is performed in purpose to prevent the volume of the bone. The preservation of the alveoli is attempted to be perform after atraumatic tooth extraction to preserve the alveolar walls and the surrounding soft tissue.
Material and methods: Preservation can be carried out with the help of autogenous, heterogeneous, alloplastic materials and materials of synthetic origin. The filled bone alveolus with any preservation material is covered with a membrane that can be resorptive or non-resorptive, which prevents the growth of connective tissue and stimulaets the guided bone regeneration.
Conclusion: After preservation of the alveolus, the patient can decide between prosthetic or implant prosthetic rehabilitation, which obtaine excellent results from an aesthetic and functional aspect.
Key words: preservation of the alveolus, aqueous tissue regeneration, resorptive membrane, alloplastic materials.
