Case for implant platform unswitching.
Platform switching was introduced to reduce marginal bone loss and therefore maintain the gingival architecture, leading to a more favorable esthetic result. In the patient presented, recession had resulted in the exposure of the implant neck and threads; this was managed with a custom-made additional prosthetic component. The result, although not ideal esthetically, provided an implant abutment interface that was easier for the patient to clean.
