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.

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.

More recently, a heating process to denature albumin in the platelet poor plasma (PPP) layer has been shown to extend the resorption time of PRF from a typical 2-week period to 4–6 months. Because of its &gt; 4 month resorption properties, extended PRF (e-PRF) membranes have been used in dentistry as an alternative to collagen membranes in alveolar ridge preservations, ridge augmentations, soft tissue grafting, and as a barrier membrane in lateral sinus grafting procedures.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Materials and Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;A total of 22 patients from 3 different clinical facilities participated in this multicenter case series study. All clinicians completed a standard lateral window sinus technique with sticky bone utilizing allograft, xenograft, or autologous dentin with an e-PRF membrane utilized for sole coverage of the lateral window. The survival rate at second stage implant surgery (~6 months) and radiographic analysis determined on consecutive radiographs: (1) the mean residual bone height (RBH) under the maxillary sinus at implant placement and (2) the change in endosinus bone level, were calculated to assess the endosinus bone changes at 6 months.&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;Between June 2022 and December 2023, 22 patients were included in this study. Patients included 12 women and 10 men with a mean age of 58.8 years, ranging from 32 to 78 years. In 22 lateral window sinuses completed, a total of 31 implants were placed. All patients healed uneventfully without any post-operative complications. Post-op CBCTs were taken at 6 months to demonstrate successful sinus floor augmentation and to calculate endosinus gain. No soft tissue invagination was encountered in any of the study participants nor displacement of the graft material into the buccal mucosa. In one case highlighted in this study, the e-PRF membrane was utilized to repair a sinus perforation. The average 6-month post-operative sinus height was 12.3 mm with a mean change in endosinus bone gain of 8.0 mm.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusion&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Utilizing extended-PRF membranes in place of collagen membranes for coverage of the lateral window during sinus floor elevation was shown to be a successful treatment modality in this case series.

Clinical measurements comprising the KM width (KMW), buccal mucosal thickness (MT), and clinical parameters were examined in a 5-year follow-up. Marginal bone loss (MBL) was evaluated with standardized radiographs using the paralleling technique. Patient-reported outcomes (PROs) during the first week post-surgery and at the 5-year follow-up were evaluated.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>KMW increased significantly during the follow-up period in both groups. The FGG group had a significantly greater KMW than the CM group at the 1, 2-month follow-up and after the 6-month follow-up. KM shrinkage was observed, and was greatest within the first 2 months post-surgery in both groups. At the 5-year follow-up, the KM shrinkage was significantly different between the groups (FGG: 47%; CM: 70%) (<i>p</i> &lt; 0.01). The MT increased significantly in the FGG group. The clinical parameters and MBL were similar between the groups. The bleeding score in the FGG group was higher than that in the CM group (<i>p</i> &lt; 0.05) within the first 2 days post-surgery, while other PROs scores were similar between groups in the first week post-surgery.

The goal of bone regeneration in sinus lift procedures is to provide a sufficient amount of newly-formed tissue to support implant osseointegration. However, it is still unclear whether there is a minimum quantity of vital bone within the newly-formed tissue required for effective support, though it is generally assumed that vital bone is essential for this process. The source and integration of new bone in maxillary sinus floor elevation procedures remain debated. Most clinical studies suggest a paramount role for sinus floor and bony walls, with a centripetal pattern of new bone formation, while conflicting reports exist regarding the osteogenic role of the Schneiderian membrane. The influence of mechanical input on peri-implant bone formation, mineralization, and maturation is significant, with bone remodeling regulated by mechanical strains generated during loading. Defining optimal loading for implants, particularly in sinus lift procedures, is challenging, as early loading may damage interfacial tissue, interfering with osteogenesis. Differences in osseointegration dynamics between native and augmented bone may arise from biological and mechanical factors, but also from patient-specific factors which should be evaluated in treatment planning. Factors to consider include sinus anatomy, patient and site-specific regenerative potential, and the selection of graft material that matches the osteogenic and mechanical requirements. Tailored approaches integrating patient-specific considerations and refined implant strategies will enhance predictability and longevity of treatment.</p>","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":"27 1","pages":""},"PeriodicalIF":3.7,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cid.13424","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142786892","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}
