Objective:
To evaluate clinical results of implant supported telescopic overdenture.
Methods:
21 patients with edentulous jaws underwent telescopic overdenture restoration. A total of 28 prostheses were fabricated. Of them, 13 were in the upper jaws, 15 in the lower jaws. Among 139 placed implants, 74 were Camcog, 28 IMZ, and 37 Frialit-2. The secondary crown was fabricated by electroforming technique and wax-lost cast method. Clinical examination and radiographs were conducted. Changes in the marginal bone level around the implants were evaluated with radiograph. The mean follow-up time was 26.5 months (range 12 - 39 months).
Results:
This type of restoration could provide sufficient stability and maintain peri-implant hygiene easily. Peri-implantitis and prosthetic complications were not observed. Marginal bone around implants was stable. No implant was lost during the loading time.
Conclusions:
The preliminary clinical results of this research showed that implant supported telescopic overdentures were predictable for edentulous patients.
