简要总结
Introduction - According to Albrektsson (1993), a successful implant should sustain less than 1.5 mm of bone loss during the first year and less than 0.2mm annually thereafter. The assessment of marginal bone loss around implants is carried out by means of periapical radiographs and more recent advances like cbct. Another important aspect is primary and secondary implant stability. Primary implant stability directly dependents on bone quality. A promising tool for assessing peri-implant bone formation is the detection of specific biomarkers in peri-implant crevicular fluid. Tgf-alpha is an important biomarker during the first stages of osseointegration, a fibrin-rich vascularized matrix populated by fibroblast-like cells is created providing a template for future bone.
Aim - the aim of this present study is to evaluate and compare the peri-implant bone loss between immediate and delayed loaded implants.
Materials & methods - For group a, 8 sites indicated for replacement of missing tooth with more than 6mm width and 10mm height of bone will be taken for implant placement with immediate loading followed by placement of healing abutment. Acrylic crown will be placed within 72hrs. For group b, 8 sites indicated for replacement of missing tooth with sufficient height of bone will be taken for implant placement with delayed loading followed by placement of healing abutment. Picf samples will be collected at 15 days, 30 days and 90 days. Isq and crestal bone levels will be measured at baseline and 3 months.
