A patient with oral submucous fibrosis and resorbed ridges poses a challenge for prosthodontic rehabilitation because of the limited mouth opening and fibrotic mucosa. The fabrication of prosthesis is very difficult due to abnormal jaw relations, influencing the long-term prognosis of the patient. To present a case of oral submucous fibrosis with severely resorbed edentulous ridges which was successfully managed by adopting a modified technique in fabricating a complete denture prosthesis. A 55-year-old female patient with completely edentulous maxillary and mandibular arches diagnosed with oral submucous fibrosis was rehabilitated with complete dentures by recording neutral zone for resorbed mandibular ridge and by arranging the posterior teeth in cross arch relation for compensation of the abnormal jaw relations. The cross-arch arrangement of posterior teeth provides a more stable and retentive complete denture prosthesis for patients with severely resorbed ridges and a wider mandibular arch.

Summary A patient with several missing teeth in the anterior aesthetic region along with severe ridge defect poses a greater challenge for prosthodontic rehabilitation. In such cases treatment using fixed partial denture (FPD) may not be feasible because of the extent of edentulous span and the periodontal conditions of the abutment teeth. To present a case of multiple missing maxillary anterior teeth with class III ridge defect rehabilitated using FPD-removable partial denture. A 38-year-old female patient was successfully rehabilitated using Andrew's bridge system in the maxillary anterior region. The fixed-removable Andrew's bridge system provides a good prognosis if diagnosed and planned meticulously.

Odontogenic tumours involving the maxilla or mandible are usually treated with surgical resection. To prevent recurrence, extensive surgical intervention might be carried out leaving the patient with anatomical defects. However, rehabilitation of such patients with an obturator can improve function, facial form and social acceptance. In this case, we have evaluated the different designs and techniques of fabrication of an obturator prosthesis used for the rehabilitation of a hemipalatomaxillectomy patient. A 40-year-old man presented with a loose fitting obturator prosthesis. He had undergone hemipalatomaxillectomy for the treatment of an ameloblastoma 2 years earlier and had been using an obturator prosthesis since then. Hollow-bulb obturator prostheses were fabricated using two different methods, the lost salt and open lid techniques. The obturator prosthesis fabricated with the lost salt technique weighed less than the patient's old obturator. But the obturator fabricated using the open lid technique did not only considerably reduce the weight of the prosthesis but also improved health, function, aesthetics, phonetics and quality of life in this hemipalatomaxillectomy patient.

Objective: To present the outcome of a case with completely edentulous poor and flabby mandibular ridge rehabilitated using liquid supported denture and conventional complete denture. Case report: A 71- year old female patient was successfully rehabilitated using liquid supported mandibular denture for the management of flabby tissues. Methodology: Initially patient was given conventional complete denture. Once the patient was comfortable and started using same denture then liquid supported denture was introduced to the patient. After all post insertion follow up appointment patient was asked to give feedback for both dentures in the form of questionnaire. Results: The post-insertion check-ups after insertion of liquid supported denture and conventional denture showed that liquid supported denture can be a promising solution to certain problematic situations such as poor and flabby ridges, which are difficult to rehabilitate prosthodontically.
