Abstract
Introduction: Poor retention, stability and margin gap due to excessive bone lose following
surgery is one of the major problems of rehabilitation in orbital defect with adhesive retained orbital
prosthesis.
Presentation of Case: This clinical report describes a simplified technique for the fabrication of an
adhesive retained silicone orbital prosthesis by proper evaluation and using of remaining tissue
undercuts to achieve ideal fit and aesthetics in a patient who has severely loss orbital bone after the surgery.
Discussion: Aesthetics will be compromised if the proper evaluation of remaining tissue and
treatment plan is not done prior prosthetic rehabilitation. To solve this issue sometimes
maxillofacial prosthodontist may have to think for implant retained facial prosthesis. This is also
sometime not possible due to several factors such as peri-implantitis, hygiene practice and dose of
radiation etc.
Conclusion: Proper use of remaining anatomical undercuts can be an alternative way to
overcome the issue.
