Immediate placement of tapered implants with a moderately rough anodized surface and smooth collar in fresh extraction sockets: A retrospective analysis with 10‐year follow‐up

Abstract

Background There is limited long‐term data on hard‐ and soft‐tissue outcomes of implants immediately placed in postextraction sockets with immediate or early loading. Purpose To evaluate the clinical outcomes of immediately placed anodized tapered implants in consecutive patients with at least 10 years of follow up. Materials and Methods This retrospective analysis evaluated outcomes of 61 consecutive patients who received 89 tapered implants with an anodized implant body and machined collar. Implants were placed in fresh extraction sites and functionalized using an immediate‐ or early‐loading protocol. Outcome measures included survival, marginal bone level change (ΔMBL), and papilla index. Results The 10‐year cumulative survival rate was 100%. ΔMBL at the 10‐year follow up was −0.86 ± 2.10 mm. At 10 years, patients had mesial and distal papilla index scores of 2 or 3 for 95.9% and 87.8% of implants, respectively. Conclusions When used for immediate placement and immediate‐ or early‐loading protocols, this implant produced excellent long‐term hard‐ and soft‐tissue outcomes.

Marginal bone level change during sequential loading periods of partial edentulous rehabilitation using immediately loaded self-tapping implants: a 6.5-year retrospective study

“…TiUnite implants showed greater first-year crestal bone loss than the other modern implants but reached a relatively steady state without further notable bone loss on an annual basis. 44 45 In the present study, pronounced bone loss was also observed from 4 years to 7.5 years, and a stable mean bone level of 2 mm, which may be coordinated with biological width, was ultimately achieved. Further study is needed to discover the causes of these findings.…”

Long‐term performance of implants with moderately rough anodized surface supporting single‐tooth restorations: A retrospective analysis with an up to 15‐year follow‐up

“…It also compares favorably with the published literature. In the studies evaluating anodized implants with a follow‐up of more than 10 years, the mean marginal bone remodeling from implant insertion or prosthetic loading to last follow‐up ranged from −1.66 to −0.60 mm (Glauser, 2016; Mozzati et al, 2015; Mura, 2019), while in another study with bone loss assessed based on implant thread exposure, 90.4% of implants showed very low bone loss of less than 1 thread (Walton, 2016). A systematic review of radiological performance of implant‐supported single crowns estimated a mean bone loss of 1.3 mm after 10 years in function (Hjalmarsson et al, 2016).…”

“…Glauser (2016) and Mozzati et al (2015) reported an 11-year and 12-year CSR of 97.1%, respectively; however, these studies were not limited to single-tooth restorations but also included partial and full arch restorations. In another study published by Mura (2019), using a tapered implant with an anodized body and a machined collar, a 10-year CSR of 100% was reported. These results suggest that anodized implants may offer a reliable solution for long-term clinical performance with survival rates better than those of machined surface implants.…”

“…Nevertheless, evaluation of longterm performance of dental implants in single-tooth indication is limited to implants with machined surfaces since the moderately rough surfaces were only introduced in the early 2000s. Although favorable short-term outcomes of moderately rough anodized dental implants have been reported (Karl & Albrektsson, 2017;Wennerberg et al, 2018), only few studies, as yet, have published data regarding the clinical performance beyond 10 years in function (Glauser, 2016;Mozzati et al, 2015;Mura, 2019;Walton, 2016). The present retrospective study suggests that implants with the anodized surface, 2019) reported a 10-year CSR of 96.4% for contemporary titanium implant systems, while a systematic review on implantsupported single crowns estimates the >10 year implant survival to be 95.0% (Hjalmarsson et al, 2016).…”
