This integration enables the development of more personalized treatment plans, ensures precise implant positioning, and strengthens communication between clinicians and patients, thereby reducing potential errors and risks. Computer-aided implant surgery consists of two primary approaches: static-guided surgery, which uses a physical surgical stent to guide the osteotomy based on the preoperatively planned virtual implant position, and dynamic-guided surgery, which employs an optical tracking system with a real-time monitor display for the visualization of implant osteotomy inside the alveolar bone. Each approach offers distinct advantages and poses unique clinical challenges. This paper provides an overview of the current applications and literature on digital treatment planning and computer-aided implant surgery, discussing the advantages and limitations of each approach. Clinical cases are presented to illustrate the digital workflow and highlight key considerations for implementing these methods. Currently, the use of digital workflow in implant dentistry is rising, and it is essential to strike a balance between precision and practicality. The future is promising, with generalized adoption anticipated.</p>\u0000 </div>","PeriodicalId":50679,"journal":{"name":"Clinical Implant Dentistry and Related Research","volume":"27 3","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143888885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study comprised three primary groups comprising 30 samples, categorized based on the isolation methods and control group. The cement excess was removed with a dental explorer probe for the control group. Moreover, three different cement materials were used: polycarboxylate, temporary implant, and resin cement. Each primary group was subdivided into three subgroups according to the type of cement used, leading to 10 samples per subgroup. Cobalt-chromium superstructures, intended to be cemented onto the implant analog-abutment complex, were fabricated using the direct metal laser sintering method. The crowns were filled with cement, and after the cementation process, any excess cement was subsequently removed using the designated isolation method. After removal, images of the cement residues at the gingival margin of the crown-abutment complex and occlusal surface of the gingiva around the implant were captured. These images were then analyzed using Adobe Photoshop CC2018, wherein excess cement was marked using the Lasso Tool to quantify the total area.
