Management of Severely Atrophied Maxillary Ridge Using Quad Zygomatic Implants

Management of Severely Atrophied Maxillary Ridge Using Quad Zygomatic Implants to Support Immediately Loaded Hybrid Prosthesis.One Year Evaluation of Occlusal Contact and Ridge Resorption

This clinical study will aim to compare and evaluate zygomatic implant stability, occlusal contact, and bone level changes around dental implants

The aim of this study will be to compare and evaluate zygomatic implant stability, occlusal contact, and bone level changes around dental implants and that of the atrophied maxilla rehabilitated with immediate loaded hyprid prosthesis supported by 4 zygomatic implants.

Inclusion Criteria:

• All patients will have healthy healed residual alveolar ridges, Angle's class I maxillomandibular relations, available maxillary restorative space. This will be verified by tentative jaw relation records.

Exclusion Criteria:

• All detrimental bad habits like smoking, TMJ clicking or TMJ dysfunction will be excluded.
