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. 

Dr. Stuart Froum

Just as Dr. Williams observed in his earlier presentation, Dr. Froum concurred that he is definitely seeing more cases of peri-implantitis than ever before, both at the NYU clinic and in his private practice. Describing peri-implantitis as an inflammatory process, Dr. Froum said that its risk can be significantly reduced by creating implant restorations that are easily maintained and cleaned as well as by removing excess biome and cement during placement.

Intermittently during the program, co-presenters Dr. Froum and Dr. Rosen alluded to and discussed the controversy surrounding the role of cement in peri-implantitis. HINT: Choose cement carefully; some are known to encourage the growth of gram-negative bacteria. And zinc polycarboxylate has been shown to corrode some implants.

They did state that peri-implantitis can be definitely linked both to plaque as well as the presence or absence of keratinized tissue. Other risk factors include poor oral hygiene, a history of periodontal disease, smoking, poorly controlled diabetes, alcohol use, and plain old genetics.

Dr. Rosen presented a systematic general treatment regimen for peri-implantitis, involving flap access, implant surface decontamination, and defect debridement and filling. He also cited a recently published protocol using air abrasion, a tetracycline slurry, sterile saline spray, and a rotary titanium brush . Another suggestion: use citric acid to remove biofilm from implant surfaces when treating peri-implantitis; it encourages clot stability.
