Placement of restorations and dental prostheses are necessary to rebuild missing teeth and to rehabilitate occlusal functions. However, design and fabrication of prostheses for the purpose in periodontally compromised dentitions should be carefully adopted in order to protect the limited periodontium from further deterioration. It highlights the need for well-balanced occlusal loading, adequate assessment of plaque control, and motivation of periodontal maintenance. Through case presentation, factors could affect periodontal prognosis, such as tooth morphology and alignment, periodontal severity, prosthetic considerations and therapeutic modalities, will be discussed.
