Effect of edentulous arch restored with implant supported telescopic overdenture

To study the effect of the edentulous arch with implant supported telescopic overdenture.

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).

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.

The preliminary clinical results of this research showed that implant supported telescopic overdentures were reliable for edentulous patients.
