A long‐term follow‐up study of non‐submerged ITI implants in the treatment of totally edentulous jaws

Abstract

In this prospective multicenter study, non-submerged ITI implants were followed in order to evaluate their long-term prognosis in fully edentulous jaws. A total of 1286 implants were inserted in 233 consecutive patients and, after a healing period of three to six months, the successfully integrated implants were restored with 163 overdentures and 95 fixed full-arch bridges. This prospective study not only calculated the 10-year cumulative survival and success rates for the 1286 implants by life table analysis, but also evaluated the actual survival and success rates for 498 implants after at least five years of functional loading. In addition, cumulative success rates were calculated for implant subgroups according to implant length and location. Additional analyses were performed to evaluate the estimated and actual survival and success rates of the implants in relation to various prosthetic rehabilitation techniques. The 10-year cumulative survival and success rates were 95.9% and 92.7%, respectively. The actual 5-year survival and success rates of the first 498 implants that were inserted were 97.7% and 95.0%, respectively. The analysis of implant subgroups showed slightly more favourable cumulative success rates for 12 mm long implants (93%), in comparison to 10 mm and 8 mm long implants (91.6% and 89.6%, respectively). The cumulative success rate for mandibular implants (approximately 94%) was also more favourable than that for maxillary implants (approximately 91%). Patients who were loaded with both maxillary and mandibular prostheses maintained success rates well above 90%; while only implants that were inserted to support maxillary overdentures that were retained by Dolder bars showed a success rate below 90%.

Dual effects and mechanism of TiO2 nanotube arrays in reducing bacterial colonization and enhancing C3H10T1/2 cell adhesion

“…Dual effects and mechanism of TiO 2 nanotube arrays 1 minute, in a mixture of HNO 3 and HF, to remove the TiO 2 nanotube arrays formed in the first anodization step and were then washed with distilled water. Subsequently, these samples were immediately anodized again under the same conditions for the desired length of time: the group of samples anodized at 10 V during the first anodization step was anodized at 10 V for 45 minutes, whereas the applied voltage for the group of samples anodized at 20 V during the first step was fixed at 20 V for 45 minutes as the second anodization step.…”

MicroCT-based evaluation of the trabecular bone quality of different implant anchorage sites for masticatory rehabilitation of the maxilla

“…While the zygomatic trabecular bone quality was previously suggested to be poor compared with the maxilla (Nkenke et al, 2003), the present intra-individual analysis proved a comparable trabecular bone quality of the zygomatic bone with the anterior maxilla. Further, both were significantly superior to the posterior maxilla, which might contribute to the inferior outcomes of implant survival rate reported for the posterior maxilla (Ferrigno et al, 2002;Weng et al, 2003). Altogether, the description of an equivalent trabecular bone quality of the zygomatic bone to that of the anterior maxilla presents valuable information for further research on zygomatic implants.…”
