However, maintaining marginal bone stability remains a crucial factor for long-term success, particularly in the case of short implants. The present multicenter prospective case–control study aimed to compare the clinical outcomes of bone-level and tissue-level short implants in the posterior maxilla, focusing on implant survival and peri-implant marginal bone stability over 1 year of function.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Fifty-nine patients who met specific inclusion criteria were enrolled and treated by three clinical centers with a total of 74 short implants, either bone-level (7 mm in length, placed 1 mm sub-crestally) or tissue-level (5 or 6.5 mm in length). The primary outcome was physiological bone remodeling (PBR) measured via radiographs at baseline (T0), prosthesis delivery (T1), and 12 months post-loading (T2). Statistical analysis was performed to evaluate differences in PBR between groups, with multivariate analysis assessing the influence of various patient and site-specific factors.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The final analysis included 58 patients who were treated with a total of 71 short implants, comprising 36 tissue-level and 35 bone-level implants (one patient dropped out as he did not attend follow-up visits on time). All implants were rehabilitated with fixed, screwed prosthetics after 5 months, with no recorded complications up to 1 year of loading. Stability was similar between the two implant types at T0 and T1, with no significant differences in insertion torque and implant stability quotient (ISQ). Multivariate analysis revealed a significant positive correlation between insertion torque and ISQ at T0, as well as with bicortical engagement of the implant apex with the sinus floor. Tissue-level implants demonstrated significantly lower peri-implant bone remodeling (PBR) compared to bone-level implants at both T1 (0.11 ± 0.27 mm vs. 0.34 ± 0.35 mm, &lt;i&gt;p&lt;/i&gt; = 0.004) and T2 (0.30 ± 0.23 mm vs. 0.55 ± 0.42 mm, &lt;i&gt;p&lt;/i&gt; = 0.003). Multivariate analysis showed a significant positive correlation between PBR (T0–T1) and thin vertical mucosal thickness (≤ 2 mm) at T0 in both tissue-level and bone-level implants. Additionally, PBR (T1–T2) in both groups significantly correlated with the use of short prosthetic abutments (≤ 2 mm) and, only in bone-level implants, with crown emergence angles &gt; 30°.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusion&lt;/h3&gt;\u0000 \u0000 ","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":"27 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cid.13428","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142831235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Of them, 27 patients (38 implants) received a single preoperative shot of antibiotics (2 g amoxicillin; Pre-op), 12 patients (19 implants) were prescribed with postoperative antibiotics for 3 days (500 mg amoxicillin, 3 x day, Post-op), and the remaining 10 patients (13 implants) did not receive any systemic antibiotics (No-Ab). Mean probing depth values (mean PDs; primary outcome), bleeding on probing (BOP), plaque (PI), suppuration (Sup), and deepest PDs values (max PD) were assessed prior to surgery (baseline), after 6 and 12 months. To assess the differences in changes in the clinical parameters, and disease resolution (PD ≤ 5 mm, ≤ 1 BOP site and no Sup) among the groups, logistic regression analyses were performed.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>After 12 months, the mean PD reduction amounted to −1.74 ± 1.56 mm, −1.91 ± 1.88 mm, and −1.13 ± 1.05 mm in the No-Ab, Pre-op, and Post-op groups, respectively, with no significant difference detected among the groups. The BOP was reduced in 60%, 59.3%, and 83.3% of the patients after 12 months in the No-Ab, Pre-op, and Post-op groups, respectively, with no significant differences among them.
