目的比较舌侧集中全口义齿和解剖全口义齿在下颌牙槽嵴重度吸收患者修复中的临床效果。方法将12例下颌牙槽嵴呈3级或4级吸收的无牙颌患者随机分为两组,采用单盲法,让患者分别戴用两种型全口义齿各3个月后,填写全口义齿使用质量评估表,医生通过吸光光度法测量花生米的咀嚼效率,记录每种型全口义齿的疼痛调改次数,采用SPSS 22.0软件对获得的数据进行统计学分析。结果在主观评分上,两种型全口义齿的美观、发音、舒适无明显差异(P>0.05),但在稳固性、咀嚼能力方面舌侧集中全口义齿的评分显著优于解剖全口义齿(P<0.05)。两者在咀嚼花生米的效率上无显著性差异(P>0.05),但舌侧集中全口义齿的疼痛调改次数显著少于解剖全口义齿(P<0.05)。结论舌侧集中全口义齿相比解剖全口义齿更适用于修复下颌牙槽嵴重度吸收的无牙颌患者。
Objective To compare the clinical effect of lingual central complete denture and anatomic complete denture in the treatment of severe mandibular alveolar ridge resorption. Methods 12 cases of mandibular alveolar ridge were graded as grade 3 or grade 4 edentulous patients were randomly divided into two groups, using single-blind method, allowing patients to wear two kinds of complete denture for 3 months, fill in The total denture use the quality evaluation table, the doctor measured the masticatory efficiency of the peanut by the photometric method, and recorded the number of the pain adjustment of each type of complete denture. SPSS 22.0 software was used to analyze the data obtained. Results There was no significant difference in aesthetic appearance, pronunciation and comfort between the two hallux complete dentures in terms of subjective scores (P> 0.05). However, the scores of lingual central complete dentures in stability and masticatory ability were significantly better than those in anatomical Complete denture (P <0.05). There was no significant difference in the efficiency of chewing peanut between the two groups (P> 0.05). However, the total number of pain changes in the lingual central complete denture was significantly less than that of the complete denture (P <0.05). Conclusion The maxillofacial ossification of the maxillofacial ossification is more suitable than the complete denture 解 of the anatomical complete denture for the restoration of mandibular alveolar ridge with severe absorption of edentulous patients.
