AI Article Synopsis
- Platform switching in implant dentistry aims to minimize bone loss around implants exposed to the oral environment.
- A study analyzed biopsy specimens from a mandibular implant removed two months after placement, revealing an inflammatory tissue response around the implant platform and healing abutment.
- The reduction in bone loss may be due to the inward shift of the inflammatory connective tissue at the implant-abutment junction, which lessens its negative impact on surrounding bone.
Article Abstract
Platform switching is a concept recently introduced in implant dentistry. It is intended to reduce the crestal bone loss that is commonly found around implants exposed to the oral environment. The aim of this study was to examine biopsy specimens to help explain the biologic processes occurring around a platform-switched implant. A mandibular implant was removed 2 months after placement because of prosthetic rehabilitation difficulties. The implant was then sectioned and subjected to histologic and histomorphometric analysis. An inflammatory connective tissue infiltrate was localized over the entire surface of the implant platform and approximately 0.35 mm coronal to the implant-abutment junction, along the healing abutment. A possible reason for bone preservation around a platform-switched implant may lie in the inward shift of the inflammatory connective tissue zone at the implant-abutment junction, which reduces its injurious effect on the alveolar bone.
