Abstract

|
Medication-related osteonecrosis of the Jaw (MRONJ) is an uncommon complication that can occur in patients receiving antiresorptive drugs. MRONJ is often reported in connection with surgical dental treatments, such as extractions. While a substantial amount of information is available on the progression and treatment of MRONJ, data regarding implant therapy for MRONJ-treated jaws is lacking. Short implants, typically 6 to 8 mm long, have been validated for effectiveness based on numerous research findings. However, the utility of ultra-short implants (<6 mm long) remains the subject of debate. In this case report, we discuss the placement of a 6 mm long implant designed to be placed as a 5 mm ultra-short implant in a healed jaw with MRONJ accompanying peri-implantitis around the lower right second molar. Successful bone healing was achieved by simultaneously removing the implant and necrotic bone, and establishing a 5 mm ultra-short implant in the healed alveolus resulted in a positive outcome. However, due to the lack of long-term follow-up studies, caution is required when considering such treatment.
