A frequent clinical situation, either in the maxillary or mandibular arch, is of a missing first premolar and first molar, resulting in fixed partial denture design in which the canine and the second molar act as terminal abutments and second premolar act as a pier abutment. It has been postulated that the tendency of terminal abutments to intrude during function results in a teetering movements, where the pier abutment act as a fulcrum. These movements will eventually result in debonding of the less retentive terminal retainer. In order to overcome this potential risk, utilization of non rigid connectors has been advised. This clinical case report describes incorporation of non rigid connector to rehabilitate pier abutment case.

The acquired defects of the palate are created commonly surgical intervention of benign or malignant neoplasms. The size and location of the defect influence the level of difficulty in prosthetic rehabilitation. Surgical intervention creates anatomic defect which forms communication among the oral cavity, nasal cavity and maxillary sinus. The goal of prosthodontist is to rehabilitate missing oral and extra oral structures with restoration of normal anatomic and physiologic function. Prosthetic rehabilitation with obturator restores the oral structures and also acts as barriers between communications among the cavities.
