Application of new dental biomaterials in horizontal augmentation of the alveolar ridge in the post-traumatic region

For the surgical technique of guided bone regeneration, the choice of available membranes until recently did not include an option that is mechanically strong, durable, synthetic and resorbable. The most commonly used resorbable membranes are made of collagen, with relatively low mechanical strength. In order to control better the degradation and improve the mechanical and chemical properties of collagen, new synthetic procedures have appeared that improve the properties of the collagen membrane. To solve these problems, a new pure magnesium barrier membrane was developed for the GBR technique. The membrane is intended to function similarly to other degradable membranes, however due to its metallic structure, it provides better mechanical properties (than collagen) and has an initial shape stability. During decomposition, its metal structure turns into magnesium salts, which are then resorbed by the body. A 25-year-old patient comes to the Department of Oral Surgery with the desire to repair partial toothlessness in the region 21-22. Clinical examination and CBCT analysis of the mentioned region showed horizontal atrophy of the alveolar ridge with insufficient width for implant placement. In the first phase, the patient underwent guided bone regeneration in a combination of autologous and xenogenic bone covered with a NOVAMag membrane and fixation screws (Botiss dental GbmH, Berlin, Germany). Patient is being monitored and no complications have been recorded. After installation, the magnesium membrane separates the regenerating bone from the soft tissue, and the gradual decomposition and generation of gases prolongs the effect of the membrane. By presenting this clinical case with the application of a new generation of biomaterials for GBR, a series of clinical research in the Croatia begins, which aims to prove all the advantages of the magnesium membrane and magnesium fixation screws.
