ABSTRACT
Objective@#To study the effect of the edentulous arch with implant supported telescopic overdenture. @*Methods@#Fifteen patients with edentulous jaws underwent telescopic overdenture restoration. A total of 26 prostheses were fabricated (11 in the upper jaws, 15 in the lower jaws) with 104 placed implants. The secondary crown was fabricated by wax-lost cast method. Clinical examination and radiographs were conducted. Changes in the marginal bone level around the implants were evaluated by radiograph. The satisfaction level of complete denture and implant-supported overdenture were compared. The mean follow-up time was 32 months (range 6-60 months).@*Results@#Twenty-six prostheses showed better stability, maintenance and occlusion. There were statistical differences between complete denture and implant-supported overdenture in comfort level and chewing function. 1 mm bone lost was found in two patients after 4 years. No implant was lost during the loading time. @*Conclusion @#The preliminary clinical results of this research showed that implant supported telescopic overdentures were reliable for edentulous patients.
