Following the general check-up and the creation of a study model, the planned implant location demonstrated an external right maxilla diameter of more than 5 mm, thereby validating the cone-beam computed tomography (CBCT) radiograph. The next step is the sinus lift operation, followed by the placement of dental implants. Production of PRF: 30 mL of venous blood was extracted and separated into three layers. The PRF was inserted into the space formed by the sinus floor and sinus membrane, and the flap was secured. The procedure involved creating an opening in the bone, separating the sinus membrane from the sinus floor, and making holes for implant insertion. The primary stability of the implant was assessed using an ISQ measurement device. Cone-beam computed tomography scans were taken and compared preoperatively, 6 months postoperatively, and follow-up assessments after 3 days, 7 days, and 6 months. And showed initial stability, pain, infection, blood bruises, peri-implant inflammation, osseointegration, bone loss around the implant, changes in bone thickness and sinus mucosa, and problems during the procedure. The Chi-squared test tested initial stability, whereas the paired sample &lt;i&gt;t&lt;/i&gt;-test analyzed bone width and height changes.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The study assessed the initial stability of a dental implant using bone density, with bones classified as D2 showing the strongest stability (76.7%). Three days after surgery, 26.7% of patients experienced mild pain, which decreased to 6.7% after 7 days. Six months later, the implant site showed no pain, no inflammation, and no bone loss. The ISQ was greater than 70, indicating strong integration with the surrounding bone. The thickness of the sinus membrane mucosa and alveolar bone changed significantly, with a significant difference (&lt;i&gt;p&lt;/i&gt; &lt; 0.05) in breadth and height.

A search methodology, specifically designed for this database, was developed using MeSH terms combined with Boolean operators such as \"AND\" and \"OR\". The Bibliometrix tool was employed to facilitate the study, using indicators including the number of citations and publications, the authorship of the publication, the country of origin, the year of publication, the type of publication, the H-index, WorldMap, Sankey diagram, keyword analysis, topic evolution, and scientific findings.</p><p><strong>Results: </strong>A total of 50.7 and 27.3% of the publications were in Q1 and Q2 quartile journals. The University of Central Lancashire has the most publications (17), but the University of California at San Francisco has the highest impact (1545 citations per publication). The journal Periodontology 2000 had a total of 643 citations per publication. Sim Kaur Singhrao (16) and Ingar Olsen (10) were the authors with the most publications, whereas Eric C Reynolds had the highest impact with 1,300 citations.</p><p><strong>Conclusions: </strong>This bibliometric study found a gradual growth in publications, with the highest number of studies during 2021 and 2022, followed by a decrease in subsequent years, with Q1 and Q2 journals predominating. In terms of scientific productivity, the United States is the leading country in this area of research. The journal Periodontology 2000 had the highest number of citations, demonstrating the particular interest of periodontology in studying the association between periodontal disease and systemic diseases.</p><p><strong>Clinical significance: </strong>The present study is significant because the relationship between periodontitis and Alzheimer is currently considered a novel multidisciplinary research opportunity, given that it includes both medical and dental specialties. This research also provides a valuable contribution to academics, universities, and research centers because it will allow us to understand trends and new research horizons and identify the most productive authors.
