It is commonly shared among implant dentistry specialists that graft-less procedures and immediate loading approaches can improve the comfort and quality of life of patients with severely resorbed edentulous maxilla and mandible.
The zygomatic anchorage concept was developed by Brånemark in the 1980s. According to different studies, a high implant survival rate (between 91% and 100%) has been described on two and four zygomatic implants; and depending on the severity of the resorption, this approach may be used as a viable and a predictable treatment to support a fixed restoration in patients with an atrophic maxilla (Bedrossian, 2010; Aparicio et al., 2014).
Moreover, in cases of atrophic maxilla, two immediate loaded zygomatic implants in each zygoma have been reported to successfully rehabilitate the patient (Malevez, 2012; Davo and Pons, 2015).
The following clinical case report describes a successful bimaxillary rehabilitation with immediate loading on 4 Straumann® Zygomatic Implants in the maxilla and 4 Straumann® Mini-Implants in the mandible. The design and properties of these implants allowed us to treat both arches without the need of grafting procedures and as consequence, to achieve an excellent patient acceptance.
