This article evaluates literature from the Pubmed/Medline database on the subject of zirconium oxide and its use in edentulous patients. The question is which type of zirconia should be used in edentulous patients, taking into account the respective prosthetic, functional and esthetic problems. It was analyzed which implant and prosthetic criteria have a positive influence on the esthetic result. It was shown that zirconium oxide frameworks can also be used for wide-span restorations, although the respective material must be carefully selected depending on the patient case. Further investigations and further development of materials and techniques in the application are necessary.
