Retrospective study on forty-eight fixtures inserted in upper jaw
Vol 34, Issue 1S2, 2020
Abstract
It is generally accepted that maxilla has a less bone quality than mandible and this fact makes implant rehabilitation more complex. Recently a new type of spiral implants has been introduced in the global market. Since few reports are available a retrospective study was performed. A total of 48 two-piece spiral implants were inserted, 21in female and 27 in males. The median age was 58 ± 8. Implants replaced 10 incisors, 9 cuspids, 25 premolars and 4 molars. Implant length was 10 mm, 11.5 mm and 13 mm in 13, 24, and 11 cases, respectively. Implant diameter was 3.3 mm, 3.75 mm and 4.2 mm in 25, 17 and 6 cases, respectively. One implant was lost, survival rate (SVR) = 97.91%. Then peri-implant bone resorption was used to investigate success rate (SCR). The mean bone resorption was 0.3 mm after an average period of 1 year follow up. In conclusion the implants studied are reliable devices for oral rehabilitation with a very high SCR and SVR.
