Abstract:

Purpose of the Study: We investigated a long-term survey on the comparison of the biological and hardware complications with removable prostheses, including implant overdenture and implant telescope (with natural teeth), in full-mouth reconstruction.

Methods: Thirty-three patients of average age 74 ± 9 years (11 males and 22 females; upper: 23 cases and lower: 17 cases) using implant telescope (included Double crown, 40 cases) and implant overdentures (8 cases) were studied from 2001 to 2019 for their clinical follow-up. Biological and hardware complications in 164 implants (Straumann®, Switzerland) and 71 teeth (average denture wearing period: 10 years and 1 month ± 5 years and 2 months) were evaluated statistically.

Results: The survival rates of the implant and natural teeth were 97% and 90%, respectively, indicating no significant difference between them. Hardware complications with implant telescopes (average: 0.8 cases/year) were less than those of implant overdentures (average: 4 cases/year), with a statistically significant difference (P < 0.05). In telescope type of prosthesis, detachment of the inner cap occurred in 23.4% cases, while implant body breakage was recognized only in one case.

Conclusion: Long-term hardware complications with implant telescopes were considerably lesser than that of implant overdentures. It was suggested that implant telescopes recovered the occlusal support over a long period.
