Abstract: Abstract：Objective To explore clinical effects of complete denture with modified jaw position record base on restoration of complicated edentulous patients Methods: 20 cases of edentulous patients with severe alveolar ridge resorption were selected. The record bases were made of light-cured resin base material, which were relined by silicone rubber impression material to obtain stability and retention, to ensure accurate maxillamandibular relationship and definitive impression with well postpalatal seal. Results: 20 complicated full denture cases were treated by modified jaw position record base. 18 cases had a stable denture and chewed well without tenderness. 2 cases had mild tenderness, but thereafter the pain was solved by selective grind. Conclusion: Edentulous patients patients with severe alveolar bone ridge resorption can finally own an ideal complete denture using modified jaw position record base to obtain accurate and stable maxillomandibular relationship and well postpalatally sealed definitive impression.
