Summary

The aim of study is evaluation of accuracy of completely versus partially limiting computer generated surgical three-dimensional guides during placement of zygoma implants in patients with atrophic maxillae.

Conditions

  • Maxillary Deficiency
  • Alveolar Bone Loss

Interventions

PROCEDURE

completely limiting computer generated surgical three-dimensional guide

Long mid-crestal incision from the right to the left maxillary tuberosity and raising a full thickness flap to expose the maxilla up to the fronto-zygomatic notch. According to the zygoma anatomy-guided approach classification and previously planned surgery using Cone beam C.T lateral window and sinus foor lifting will be decided to be done or not. After securing the surgical templates in its proper position, sequential osteotomy drilling will be performed in a steady in and out movement under copious sterile saline irrigation.The drills will be entering the maxilla palatally and puncturing the alveolar crest to reach the buccal side.The drills will be visualized through the bony window created until it reaches the zygomatic bone.Sequential drills with the uses of guided tubes,sleeves and keys will be used to guarantee that the implant have been placed in a fully completely guided manner.Afterwards the zygomatic implants will be placed.

PROCEDURE

Partially limiting computer generated surgical three-dimensional guide

Long mid-crestal incision from the right to the left maxillary tuberosity and raising a full -thickness flap to expose the maxilla up to the fronto-zygomatic notch. According to zygoma anatomy-guided approach classification and previously planned surgery using cone beam C.T.lateral window and sinus floor lifting will be decided to be done or not.After securing the surgical templates,The first drill only will be used using the guide then it will be removed and the other drills will be completed in a free hand without the use of guide to guarantee that the implant will be placed in partially guided manner.Afterwards the zygomatic implants will be placed.
