ClinConnect Summary

Early marginal bone loss (EMBL) is a non-infective remodeling process of peri-implant crestal bone occurring within the first year after implant insertion. EMBL has a multifactorial etiology, being influenced by various surgical and prosthetic factors, including insufficient crestal width, surgical trauma, biological width formation, microbial colonization of implant-abutment micro-gap, horizontal implant-abutment mismatch ("the platform-switching concept"), the number of abutment connection/disconnections, prosthetic abutment height, design and mechanical stability of implant-abutment conn...
