Trans-sinus implants suitable option for rehabilitation of atrophic edentulous jaws, finds study

A new study published in the Journal of Prosthetic Dentistry showed that although trans-sinus implant could be a good choice for treating an atrophic maxilla. When there is not enough bone height in the upper jaw, dental implants can be placed via a surgical technique called trans-sinus implant surgery. Using this technique, the implant is positioned to pass into the sinus cavity and become partially embedded in the sinus floor, providing stability and support for the dental prosthesis. There are not enough systematic evaluations to assess how well trans-sinus dental implants work for oral rehabilitation in individuals with atrophic maxilla. To ascertain the efficacy of trans-sinus dental implants placed in patients with an atrophic maxilla, Pedro Henrique and his team carried out this systematic research.

According to predetermined inclusion and exclusion criteria and the question if trans-sinus implants can be an appropriate choice for the rehabilitation of the atrophic maxilla, five databases including the nonpeer-reviewed literature up until March 2024. Using a 95% confidence interval, the Revman software tool was employed for the meta-analysis of the variables implant loss and marginal bone loss. The ROBINS I technique was used to assess the studies' risk of bias.

4 of the 1884 articles that were initially discovered in the databases under investigation were included in this systematic evaluation. One was a randomized clinical study, while the other 3 were observational studies. With a 97.2% efficacy rate, a total of 144 patients with 658 implants (207 of which were trans-sinus) were assessed. When comparing trans-sinus implants to conventional implants, there was no statistically significant difference in efficacy, and there was no statistically significant difference in the marginal bone loss of the groups. A low risk of bias was not found in any of the examined research.

Overall, a viable and highly successful approach for the rehabilitation of atrophic edentulous jaws is the use of trans-sinus implants. The limited amount of controlled research on the topic and the significant chance of bias, however, are crucial aspects that need to be taken into account before selecting this treatment.
