摘　　要：目的探讨疑难无牙颌患者使用改良颌位记录基托行全口义齿修复的修复效果。方法选择20例牙槽嵴重度吸收的无牙颌患者,用光固化树脂基托材料制作记录基托,在基托组织面内衬硅橡胶印模材料形成具有良好稳定性和固位力的改良记录基托,以确保取得精确的上下颌关系及良好后堤封闭的闭口终印模。结果采用改良颌位记录基托制作疑难全口义齿20例,其中18例患者感义齿稳固,咀嚼功能好,无压痛。2例患者感黏膜稍有疼痛,通过调改后均取得满意效果。结论对牙槽嵴重度吸收的无牙颌患者,采用改良颌位记录基托可以获得精确稳定的颌位关系及具有良好后堤封闭的闭口终印模,最终拥有一副理想的全口义齿。Objective To explore clinical effects of complete denture with modified jaw position record base on restoration of compli- cated edentulous patients. Methods 20 cases of edentulous patients with severe alveolar ridge resorption were selected. The record ba- ses were made of light-cured resin base material, which were relined by silicone rubber impression material to obtain stability and reten- tion,to ensure accurate maxillamandibular relationship and definitive impression with well postpalatal seal. Results 20 complicated full denture cases were treated with modified jaw position record base. 18 cases had a stable denture and chewed well without tender- ness. 2 cases had mild tenderness, but thereafter the pain was solved by selective grind. Conclusions 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.
