The One Abutment–One Time Protocol
Frequently disconnecting and reconnecting healing abutments, impression copings, provisional abutments and definitive abutments is believed to compromise the peri-implant mucosal barrier, move the connective tissue zone apically and increase bone remodeling at the implant platform. Based on this reasoning, the “one abutment–one time” protocol1,2 was developed, placing the definitive restorative abutment concurrently with the implant to reduce marginal bone loss over time. Does this protocol truly lead to a significant reduction in marginal bone loss in the short and long term? Are other factors involved? This issue of Prosthodontics Newsletter considers these questions.
