Use of Anatomical Undercut in Adhesive Retained Orbital Prosthesis: An Alternative to Osseointegration to Improve Retention and Reduce Margin Gap.

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.
