Three Methods Of Repairing Periodontal Escort Off The End Missing Comparative Study

Objective: To explore the new periodontal diseases denture repair method.Methods: by using three-dimensional finite element analysis method, weretested and compared for removable partial dentures, telescopic denture,composite denture (attachments and telescopic crowns combined) repair ofmandibular bilateral periodontal diseases denture abutment and periodontaltissue stress; randomly selected24cases of mandibular bilateral periodontaldiseases denture patients, is divided into A, B two groups in age, sexdistribution, and the defect of dentition case matching.On three repair methodsfor clinical observation and masticatory efficiency comparison, two groups ofpatients were removable partial denture with telescopic denture, removablepartial denture with composite denture itself.Then the telescopic denture andcomposite denture group comparison.Results:1, the telescopic denture and composite masticatory efficiency,comfort, beauty and so superior to removable partial denture;2, composite denture with telescopic crown denture masticatory efficiencyhas no obvious difference in.3, removable partial denture abutment maximum stress for2.17MPa,crown telescopic abutment maximum stress is1.79MPa, compound denturemaximum stress of0..85MPa composite.Conclusion:1, through3D finite element modeling analysis proves thatthe composite denture treatment in periodontal diseases denture effect best,abutment maximum stress value of0.85MPa, only the47%telescopic crownremovable partial denture, as of39%.2, composite denture (crown and attachment joint) relative to the sleevecrown, in the repair of periodontal diseases with mandibular distal-extension absence, of edentulous alveolar ridge stress is smaller, edentulous alveolarridge of the maximum stress value of3.179MPa,3.732MPa and telescopiccrown.
