ABSTRACT Objectives Methods Results Conclusions This retrospective study aimed to evaluate the clinical outcomes associated with zygomatic implant (ZI) rehabilitation in partially atrophic edentulous maxillae over a mean follow‐up period of more than 10.3 years.All consecutive patients underwent ZI rehabilitation between 1999 and 2020, with a minimum follow‐up period of 3 years. The primary outcome was the implant survaival rate. Secondary outcomes included the prosthesis success rate, complications, and Oral Health‐Related Quality of Life.Of the 21 patients, treated with 27 ZIs and 48 conventional implants (CIs), 9 (42.9%) were females. The mean follow‐up was 10.3 ± 5.7 years (range 3.2–23.4). ZI and CI survival rates were 100% and 97.9%, respectively, with one CI that failed. Eleven patients received 12 CIs placed in the pterygoid and tuberosity region. Most of the implants (81.33%) were immediately loaded, with 17 patients (80.9%) receiving 21 acrylic bridges. Of the total of 26 definitive prosthesis, the success rate was 96.1%. Local inflammation (n = 2) and soft tissue recession (n = 1) were reported as complications, occurring at a mean follow‐up of 4.5 and 3.2 years, respectively. The mean score of the OHIP‐14 questionnaire was 1.19 ± 1.99.Unilateral ZI rehabilitation was a predictable option for patients with partially atrophic edentulous maxilla who have experienced previous graft or implant failures, or who require immediate loading. Splinting the ZI with CI for restoration appeared to be essential in unilateral ZI treatment. Complications were infrequent and could be managed effectively, with patient‐reported outcomes indicating normalization in quality of life. [ABSTRACT FROM AUTHOR]

Aim: To assess the correlation between the periodontal phenotype (PP) and sinus membrane thickness (SMT) in humans. Methods: This review was conducted according to the PRISMA guidelines. Two reviewers independently carried out electronic and manual literature searches of studies published in English, German, and Spanish, from 1970 to September 2022 in four electronic databases, PubMed/Medline, Scopus, Cochrane Library, and Web of Science, in addition to gray literature. Studies that assessed the correlation between PP and SMT in adults (aged 18 years) were included. Methodological quality was evaluated using the Appraisal Tool for Cross‐Sectional Studies (AXIS) for articles that met the eligibility criteria. Results: Six studies, including 510 patients, were considered for qualitative analysis. All included studies were cross‐sectional, and the correlation between the PP and SMT was evaluated, finding a positive and high correlation in 83.3% of them, based on a value of ≥0.7. All the included studies were assessed with a high overall risk of bias. Conclusions: Periodontal phenotype and sinus membrane thickness are likely correlated. Nevertheless, further standardized studies are required to draw definitive conclusions. [ABSTRACT FROM AUTHOR]

Objectives: This experimental study compared the accuracy of implant insertion using the free-hand (FH) technique, static computer-aided surgery (S-CAIS), or dynamic computer-assisted surgery (D-CAIS) and to evaluate the correlation of learning curves between surgeons' experience and surgical time., Materials and Methods: Thirty-six models were randomly assigned to three groups (FH, n = 12; S-CAIS, n = 12; D-CAIS, n = 12). Each model was planned to receive four implants in the maxillary anterior and posterior regions. Twelve participants, six experienced surgeons, and six dental students were included in this study. The primary outcome was the deviation between the planned and final implant placement from each group. Secondary outcomes were each technique's learning curve regarding surgical time., Results: The average deviation at implant platform, apex and gradual deviation with FH technique were 1.31 ± 0.88 mm, 1.75 ± 0.9 mm and 6.67° ± 3.70°, respectively. The average deviation of implant platform, apex and angular in S-CAIS were 0.67 ± 0.32 mm, 1.00 ± 0.39 and 2.66° ± 1.77°, respectively. The average deviation of implant platform, apex and angular in D-CAIS were 1.14 ± 0.70 mm, 1.23 ± 0.58 and 3.20° ± 2.16°, respectively. Significant discrepancies at the implant platform, implant apex, and angular deviation were found between all surgical methods (p < 0.016). Learning curves were evident after multiple implant insertions using both freehand and S-CAIS., Conclusion: The findings indicate that computer-assisted implant insertion leads to a more precise implant alignment than implants inserted freehand in an experimental set-up., (© 2025 The Author(s).
