In May, 400+ clinicians attended Straumann's day-long Dental Implant Complications symposium. Topics discussed including identifying and addressing implant complications, understanding the reasons they occur, determining treatment and solutions, and understanding how to avoid them through prevention methodologies such as proper planning, patient selection and timely treatment. Here are some highlights from one of the six presentations.
The causes of implant complications involving soft tissue are numerous. According to Dr. Pasquinelli, they include, but are not limited to: chronic inflammation, loose and/or poorly made components, poorly placed implants, abutment contour, deficient bone or soft tissue, deficient bone levels on adjacent teeth, proximity of adjacent teeth, angulation, restorative platform positioning that is too shallow or too deep, implant positioning that is too far facial or too far palatal. In other words, just about everything!
Additionally, like Dr. Froum, Dr. Pasquinelli acknowledged the cement controversy. Too much or subgingival cement dissects and coats the implant, and can go into bone. Including the obvious use of screw-retained implants, solutions for preventing the ?cement problem? include keeping margins less than 1 mm apical to the free gingival margin, leaving a reservoir (vent holes) in the abutment, using radiopaque cement, and anesthetizing the patient so the clinician can go subgingival.
