Abstract
PurposeThe purpose of this study was to evaluate the success of Immediate Loading protocol using Zygomatic Implants as remote anchors in combination with 4 conventional implants in the anterior maxillae region in the prosthetic treatment of severely resorbed maxillae. Material y MethodsThis clinical study included a total of 48 immediately loaded implants distributed among 16 bilateral zygomatic implants (Branemark Nobel Biocare) in combination with 32 conventional implants (Replace Select Tapered Nobel Biocare and SFB Alphabio TEC) in the anterior region maxillae. Hybrid prostheses were installed with metal screws/ cross arch resin without cantilevers extensions 24 to 48 hrs. after implant surgery, in a total of 8 patients with completely edentulous maxillae, 5 women and 3 men with a mean age of 52.5 years, who met the inclusion criteria ResultsAll patients selected for this clinical work were operated on successfully without surgical complications during implant insertion, obtaining an average of implant stability (ISQ), measured with the Ostell Mentor instrument, of 72.3 for zygomatic implants and an average surgical insertion torque for the conventional implants of 46.4Ncm. The success rate for zygomatic implants and conventional implants, as well as for the prosthesis treatment was 100% after 18 months of functional loading. ConclusionsWith the limitations of this preliminary study, the indication and installation of zygomatic implants for the treatment of severely resorbed maxillae, under the form of Immediate occlusal function is a highly efficient alternative, without long waiting times for patients (reported cases).
