Saleh,&nbsp;Hong-Chang Lai,&nbsp;Matteo Sangiorgi,&nbsp;Giovanni Zucchelli,&nbsp;Tiziano Testori","doi":"10.1111/cid.70007","DOIUrl":"https://doi.org/10.1111/cid.70007","url":null,"abstract":"<p>Maxillary sinus elevation is a critical procedure in dental implantology, often necessary to address bone deficiencies in the posterior maxilla. However, various medical conditions, local factors, and surgical complexities can significantly influence the outcomes. This article delves into the implications of systemic conditions such as smoking, diabetes, osteoporosis, antiresorptive and antiangiogenic medications, radiotherapy, immunocompromised states, cardiovascular diseases, chronic alcoholism, and oxidative stress on sinus floor elevation and associated dental implant placements. Each condition presents unique challenges and necessitates tailored clinical considerations to mitigate risks and enhance surgical success. A comprehensive pre-operative assessment is essential, including detailed patient history and radiographic evaluation. Local conditions affecting the maxillary sinus, such as sinusitis, require careful examination and possible otolaryngologist consultation. The article discusses a standardized Digital Surgical Planning (DSP) protocol involving CBCT imaging, intraoral scans, virtual diagnostic wax-ups, and guided implant placement to optimize surgical planning and outcomes. Surgical techniques for lateral window antrostomy are examined, including flap design, window size and location, and piezoelectric and rotary instrumentation. Subsequent regenerative procedures involve meticulous membrane elevation and particulate graft placement, with considerations for graft material and technique to ensure stability and volume retention. Post-operative care, encompassing antibiotic prophylaxis, corticosteroid use, and decongestants, is outlined to prevent infections and manage edema. Conclusively, the article stresses the necessity for implantologists to be proficient in various techniques and make evidence-based decisions tailored to individual patient needs, ensuring optimal implant therapy outcomes. The lateral window approach remains a cornerstone of regenerative dental procedures, maintaining its significance through evolving methodologies and clinical advances. The lateral window sinus elevation procedure has demonstrated consistent success as a pre-prosthetic surgical intervention for over four decades, supported by multiple reviews. Initially a hospital-based procedure requiring autogenous bone harvesting, it has evolved into a minimally invasive, office-based procedure without the need for donor bone. Smaller access windows and flaps have further reduced morbidity. Despite the emergence of less invasive techniques such as the transcrestal approach and the use of tilted or short implants, the lateral window procedure remains relevant due to its unique advantages: Provides greater access to overcome obstacles like septa. Facilitates single-surgery management of multiple implant sites. Remains applicable regardless of residual crestal bone height. Allows intraoperative management of complications such as membrane perforations.</p>","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":"27 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cid.70007","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143925999","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}

For each implant position, mean linear (Δ<i>X</i>, Δ<i>Y</i>, Δ<i>Z</i> axes) and angular deviations (ΔANGLE) and three-dimensional (3D) Euclidean distances (ΔEUC) were measured as primary outcomes with a dedicated software program (Hyper Cad S, Cam HyperMill, Open Mind Technologies) and reported as descriptive statistics. Secondary aim was to determine using linear mixed models whether implant number affected trueness. All statistical analyses were conducted using Stata 18 (Stata Corp, College Station) and significance was set at 0.05.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>A total of 30 definitive casts with 4 (<i>n</i> = 13), 5 (<i>n</i> = 8), and 6 (<i>n</i> = 9) multi-unit abutment (MUA) analogs were analyzed (<i>n</i> = 146 implant positions). The mean deviations along the <i>X</i>-axis were −3.97 ± 32.8 μm, while along the <i>Y</i>-axis, they were −1.97 ± 25.03 μm. For the <i>Z</i>-axis, a greater deviation of −33 ± 34.77 μm was observed. The 3D Euclidean distance deviation measured 57.22 ± 27.41 μm, and the angular deviation was 0.26° ± 0.19°. Statistically significant deviations were experienced for Δ<i>Z</i>, ΔEUC, and ΔANGLE (<i>p</i> &lt; 0.01). Additionally, the number of implants had a statistically significant effect only on the <i>Z</i>-axis deviation (<i>p</i> = 0.03).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Within study limitations, IPG technology was feasible for complete-arch digital implant impression with mean linear, angular, and 3D deviations far below the acceptable range for a passive fit. Reported IPG trueness might avoid a rigid prototype try-in. The implant number had no influence on trueness except for Z-axis deviations. Integrating photogrammetry with intraoral optical scanning (IOS) improved practicality, optimizing the digital workflow. Further clinical trials are needed to confirm these findings.</p>\u0000 </section>\u0000 </div>","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":"27 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/cid.70049","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143919373","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}

Sinuses to be lifted were randomized into three groups: piezosurgery with a surgical guide, a specially designed bur for lateral sinus lift, and conventional burs. Intraoperative complications, ease of access, and operation time were recorded. Pain measured with visual analog scale (VAS) and analgesic consumption were evaluated over 1 week postoperatively. Edema was evaluated preoperatively and on the 2nd and 7th postoperative days.
