Objective To compare the clinical effect of different materials dentures in repaired of teeth. Methods A retrospective analysis of 570 patients with framework removable partial dentures , which were divided into the Vitallium 2000 group, the pure titanium group and the Co-Cr alloy group randomly from Jan. 2010 to Dec. 2012 in our hospital. Compare the clinical effect of three groups. Results The emplacement rate (χ2=10.283,P<0.05)and the 2-week adjust rate (χ2=16.262,P<0.05)of three groups were statistical different significantly. The incidence rate of denture stomatitis(χ2=12.773,P<0.05),the masticatory efficiency(t=8.194,P<0.05)and the incidence rate of adverse reactions (χ2= 6.028,P < 0.05)of three groups were statistical different significantly. The patients′satisfaction (χ2=2.191,P>0.05)of three groups weren′t statistical different significantly. The degree of comfort(χ2= 6.827,P < 0.05),the speech satisfaction(χ2= 6.002,P < 0.05) and the chewing speech satisfaction (χ2=5.838,P<0.05)three groups were statistical different significantly. Conclusion The clinical effect of the Vitallium 2000 group is better of weight , strength and stability than other groups. The Vitallium 2000 frame removable partial denture is nontoxic , fastness and no peculiar smell , which could be ensure the aesthetics , the degree of comfort and improve the masticatory efficiency , worthy to recommend its clinical use.

The data of 10 cases of traumatic extra-articular ankylosis of temporomandibular joint(TMJ),including the type of trauma and the type of ankylosis,pathology,treatment method,prognosis,and so on were collected and analyzed.A reference of diagnosis and treatment is provided.

OBJECTIVE: To explore the influencing factors for curative effect of maxillofacial fractures. METHOD: Retrospective analysis of the 86 patients for maxillofacial fractures from Jan. 2008 to Dec. 2010 in our hospital, to observe data, sex, type, reason, associated injury, methods of treatment, and so on. RESULT: The success rate of curing was 95.35%. The length of stay for the 86 patients was from 7 days to 28 days, average 16. 8 days. The type, reason, associated injury, methods of treatment were the influencing factors for curative effect of for maxillofacial fracture. The success rate of curing for different ways of operation were different. Recovery rate of operation was 6.097%, it of expectant treatment was 75%, they were statistical different significantly (P < 0.05). CONCLUSION The type, reason, associated injury, methods of treatment were the influencing factors for curative effect of for maxillofacial fracture.
