Indications, techniques and complications associated with full-arch rehabilitation using trans-sinus implants: A
Purpose:
To evaluate the failure rate of trans-sinus implants for full-arch rehabilitation in atrophic maxillae, comparing their outcomes to those achieved with axial and tilted implants.
Materials And Methods:
The review followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines, including studies where patients underwent rehabilitation with trans-sinus implants alone or in combination with axial or zygomatic implants. The review was registered on the International Prospective Register of Systematic Reviews (ID: CRD42024537320). A meta-analysis using Haldane and hybrid corrections compared failure rates between implant types.
Results:
Out of 2,359 articles, 10 studies employing trans-sinus implants were selected. In the meta-analysis, the trans-sinus group was composed of 232 implants, 5 of which failed, compared to 5 of the 675 implants in the axial/tilted group. There were no statistically significant differences in failure rate between the groups (RRHaldane = 2.80, 95% confidence interval 0.89 to 8.77, P = 0.076; RRHybrid = 2.74, 95% confidence interval 0.91 to 8.17, P = 0.070). The pooled analysis indicated a comparable success rate.
Conclusions:
Trans-sinus implants represent a viable alternative, in terms of survival rate, to axial/tilted implants for rehabilitation of the atrophic maxilla, minimising the need for invasive procedures such as extensive bone grafting; however, further controlled clinical trials with longer follow-up periods are needed to confirm these results.
