Clinical Case Report Of Combined Clasp Anti-insertion For The Restoration Of Molar Food Insertion

Objective: To discuss the causes of molar food insertion,and to observe the clinical effection of combined clasp anti-insertion for the restoration of the insertion,in order to provide an effective and suitable reference for the treatment of molar food insertion.Methods: A total of 43 cases(15 males and 28 females,aged 43-67 years,mean 58 years)were selected from December,2014 to December,2016,who were diagnosed as molar food insertion in our hospital.After obtaining the patient's informed consent,90 teeth had been a perfect periodontal treatment,and then the combined clasp anti-insertion was put into used.Through two ways,which were effective and ineffective to determine its clinical effect.Effective: patient have no obvious symptoms,the affected area has no occurred food insertion or food insertion symptoms improved markedly,good chewing function,restoration stability,foreign body sensation is small,no significant impact on the pronunciation,gingival of the affected area is normal,no significant periodontal pocket,it have no periodontal membrane space widening or the bone resorption through X-ray.Invalid: the patients feel discomfort,the symptoms of food insertion have no remission,or even more serious,gingival papilla is redness and swollen?bleeding and pyorrhea,deep periodontal pocket,clasp exfoliation,abutment tooth pain and loosen.After repairing for 2-24 months,the status and clinical effect of the affected area and the restoration are comprehensively evaluated.Results: 43 cases(90 teeth)were repaired by the combined clasp anti-insertion after a perfect periodontal treatment.Followed up for 2 ~ 24 months,41 cases were in an effective treatment,the effective rate was 95.4%.This part of patients had a good response to the combined clasp anti-insertion.The symptom of food insertion was obviously improved or completely disappeared.The masticatory function was good.The restorations were stability.The gums had no obvious inflammation.The foreign body sensation was small and acceptable.The other 2 cases were failure.One case was the restorations exfoliation after two days,and the gingival papilla had no redness and bleeding,the teeth had no loosen or pain,so the restoration was re-adhesive,followed up observation for 5 months without abnormal.The other case of was an anti-insertion with metal wings surrounded by a single tooth.The patient have symptom of chewing pain and gum bleeding after two weeks.Gum redness and swollen?percussion(+)?horizontal pain was more than vertical pain?tooth mobility I?,clasp has no loosen,without food insertion?supra-occlusion.Analysis of the reason for the restoration maybe was that the gingivitis had not been cured completely or gingival was oppressed.To remove the anti-insertion,and subgingival scaling with local anesthesia,to renew restoration after healing,follow-up observation for 7 months without abnormal.Conclusion: To choose the suitable cases,combined clasp anti-insertion can solve the vertical and horizontal type of food insertion.And the restoration is small,less injury to abutment tooth?clinical operation is simple ?without picking wear? less expenses ?lasting effect?have no bad influence on oral soft and hard tissue,the satisfaction rate of patients is quite high.
