Abstract:
Objective To summarize and analyze the clinical experiences of treatment of complicated geriatric odontoptosis for the purpose of establishing a better technique to cope with such situation.Method The data of 542 outpatients with geriatric odontoptosis,from 1998 till the present treated in the Department of Outpatient,General Hospital of PLA,were summarized and analyzed according to the type and location of odontoptosis,with complications such as severe attrition,periodontitis,food impaction and detective occlusion.The special prosthetic designs on certain cases were also summarized.Some cases were followed-up.Results Removable partial dentares(RPD)with cast framework were prescribed to the geriatric odontoptosis patients.According to the site and type of odontoptosis,four special designed frameworks include casting fence-wall enforced artificial tooth prosthesis for lower clearance cases,metal strengthened plastic occlusive pad or metal occlusive pad for severe attrition cases,casting splint prosthesis for periodontal and food impaction with impaction preventive denture.36 cases were followed up for two years with satisfactory result in 31 cases,but in four cases the clasp was broken.In the cases with failure the dentures were redesigned and fabricated with cast framework,and better results were accomplished.Generally,the patients were accustomed to the new RPD quickly and revisit times were less frequent.The strength of prosthesis was enhanced.It was proved that custom designed framework could solve the clinical dilemma of severe dentition attrition,food impaction and periodontitis,and the odontoptosis was repaired.Conclusion The designed fence-wall prosthesis,metal strengthened plastic occlusal pad and metal occlusal pad,casting splint prosthesis and casting food impaction stop are effective prosthetic procedure for certain cases.
