Clinical Trial Summary
Oral rehabilitation by dental implants in the severely atrophic maxilla often represents a
challenge. To overcome this difficulty, bone augmentation procedures such as sinus
augmentation, guided bone regeneration (GBR), or distraction osteogenesis have been used to
obtain adequate bone height and width for proper three-dimensional implant placement. To
avoid surgical morbidity and shorten treatment length, alternative methods such as short or
tilted implants, as well as zygomatic implants (ZIs),have been proposed and have shown
promising outcomes.
Description:
Placement of dental implants in the pterygo-maxillary region provides adequate posterior bone
support for the prosthesis which permits better distribution of masticatory forces without
the need of sinus floor augmentation, onlay and inlay grafts, split crest technique, or
osteogenic distraction. This allows rehabilitating patients with satisfactory full arch fixed
maxillary prosthesis, which is usually spanned from second molar to contralateral second
molar tooth.
The purpose of the present study is to compare the Reliability of all on four by 2 zygomatic
implants with 2 conventional implant in anterior region versus all on four approach by
conventional implant for the rehabilitation of the atrophied maxilla in terms of survival
rates and improving the quality of patient's life and involved complication with maxillary
sinus.
