Abstract:
OBJECTIVETo discuss the technique of installation of zygomatic implants in severely resorbed edentulous maxillae, and maxillary defect.
METHODSFive patients received 8 zygoma implants and 11 dental implants. On the basis of an axial spiral CT data, anatomical models of natural size were manufactured using CAD/CAM system and before operation preoperative measurements of relevant parameters (length, areas, and volumes) carried out. Theses maxillary and zygomatic measurements obtained were referred for installing zygomatic implants.
RESULTSThe ideal direction and position of installation of the 8 zygomatic fixtures were obtained in 5 patients. The anatomical model and surgical plate were used for preoperative planning and intraoperative control of the insertion of zygomatic fixtures. The implants could be positioned precisely as preoperatively planned. The length of the zygomatic implants was between 40 mm and 50 mm.
CONCLUSIONSThe use of surgical drilling guides should be encouraged for zygomatic implant placement. 3-D image data and anatomical models improves preoperative planning and facilitates clinical procedure.
