Internal Irrigation Surgery
Evaluation of an Internal Irrigation Surgical Guide to Reduce Heat Generation During Dental Implant Surgery
Heat generated during osteotomy and implant placement may cause thermal injury to bone and adversely affect healing and osseointegration. External irrigation is commonly used to reduce heat generation; however, cooling may be less effective at the drill-bone interface, particularly during guided implant surgery.
Surgical guides with integrated irrigation channels have been developed to deliver coolant more directly to the osteotomy site, but clinical evidence regarding their effectiveness remains limited. This study will evaluate whether an internal irrigation surgical guide system reduces heat generation during osteotomy compared with a conventional guided implant surgery approach. The study will also assess clinical outcomes associated with implant placement. The findings may help inform safer and more effective protocols for guided dental implant surgery.

상세 설명
Heat generation during osteotomy and implant placement is a critical concern in implant dentistry, as excessive temperatures can lead to bone necrosis, impaired healing, and early implant failure. A temperature increase of 10°C can be considered a threshold for potential issues. Bone cell damage can occur if the temperature reaches 47°C.3 A temperature of 47°C for 1 minute can impair implant osseointegration. The current standard of care involves the use of external irrigation to reduce heat generation during the drilling process. However, this method has limitations including poor visibility of surgical site, uneven cooling at the drill-bone interface, and inability to directly cool in guided surgery.
To address these concerns, recent innovations include surgical guides with integrated irrigation channels, which direct cooling fluid more efficiently to the drilling site and may reduce the risk of heat-induced bone injury. However, clinical evidence supporting the superiority of these advanced irrigation guides over traditional designs is still limited, highlighting the need for further research to optimize both surgical safety and outcomes.
This study aims to evaluate the effectiveness of an internal irrigation surgical guide system in reducing heat generation during osteotomy and improving outcomes of dental implant surgery. The findings from this study could inform clinical practice and contribute to the development of safer, more effective implant placement protocols.
