A recent study published in the Journal of Prosthetic Dentistry suggests that trans-sinus implants may be an effective treatment for patients with atrophic maxilla, a condition marked by insufficient bone height in the upper jaw. Trans-sinus implant surgery allows dental implants to be placed through the sinus cavity, where they are partially embedded in the sinus floor, providing added stability for dental prosthetics.
Due to limited systematic evaluations on the effectiveness of trans-sinus implants for rehabilitating atrophic maxilla, researcher Pedro Henrique and his team conducted a comprehensive analysis to assess their efficacy. The study examined data from five databases, including both peer-reviewed and non-peer-reviewed literature up to March 2024. Using RevMan software for meta-analysis, they analyzed implant loss and marginal bone loss, applying a 95% confidence interval. The studies’ risk of bias was measured using the ROBINS-I tool.
Out of 1,884 articles initially reviewed, only four studies met the criteria for inclusion: one randomized clinical trial and three observational studies. The analysis included 144 patients with a total of 658 implants, of which 207 were trans-sinus implants. Results showed a 97.2% success rate for trans-sinus implants, with no statistically significant differences in efficacy or marginal bone loss compared to traditional implants. However, none of the included studies showed a low risk of bias.
Overall, the findings indicate that trans-sinus implants can be a highly effective option for treating atrophic edentulous jaws. Nonetheless, the researchers caution that the limited controlled studies and potential for bias are significant factors to consider before opting for this treatment approach.
