Bisphosphonate (BP) drugs are a commonly prescribed group of medications used in the treatment of metabolic and oncologic bone disorders. The aim of this study was to conduct a systematic review in order to evaluate whether patients on BP therapy are appropriate candidates for dental implants as compared to patients not taking BP drugs with respect to successful implant osseointegration and the risk of developing bisphosphonate-related osteonecrosis of the jaw. Based on the current literature, a history of oral or intravenous BP use is not an absolute contraindication for dental implant placement, and dental implants can osseointegrate successfully in this patient population. Importantly, the studies currently available on this topic are of moderate to weak strength of evidence with inherent bias and limitations, and hence results must be interpreted in this context. Well-controlled studies with higher strength of evidence and larger population sizes are required to address this topic more accurately in the future.

IntroductionGaucher disease is an autosomal recessive systemic condition, and the most common of the lysosomal storage disorders. It is characterized by lipid accumulation in certain cells and organs, particularly macrophages, which appear on light microscopy as ’Gaucher cells’ or vacuolated lipid-laden reticuloendothelial cells. Long bone involvement is common in Gaucher disease, whereas craniofacial bone involvement is extremely rare. Reports confirming the diagnoses of Gaucher disease involving craniofacial bones by histopathologic evidence are even rarer.Case presentationA 46-year-old Caucasian Ashkenazi Jewish woman with Gaucher disease presented with jawbone pain and lytic radiographic lesions of her mandible. Surgical biopsy of a mandibular lesion revealed Gaucher cells infiltrating the mandible, which correlated with radiographic and clinical findings, supporting a diagnosis of Gaucher disease with jawbone involvement.ConclusionsLysosomal storage diseases can have head and neck manifestations, and bone involvement in Gaucher disease is common. Therefore, careful consideration of signs and symptoms and medical history, with a thorough review of systems, is important when evaluating patients with lysosomal storage disorders to rule out head and neck involvement of disease. Biopsy may be warranted in some cases for more definitive diagnosis of painful jawbone lesions and to rule out other odontogenic and non-odontogenic conditions in the differential diagnosis.

Bisphosphonate (BP) drugs are a commonly prescribed group of medications used in the treatment of metabolic and oncologic bone pathoses. The aim of this study was to conduct a systematic review in order to evaluate whether patients on BP therapy are appropriate candidates for dental implants as compared to patients not taking BP with respect to successful implant osseointegration and the risk of developing bisphosphonate-related osteonecrosis of the jaw (BRONJ). Based on the current literature, a history of oral or intravenous BP use is not an absolute contraindication for dental implant placement, and dental implants can osseointegrate successfully in this patient population. Importantly, the studies currently available on this topic are of moderate to weak strength of evidence with inherent bias and limitations and hence results must be interpreted in this context. Well-controlled studies with higher strength of evidence and larger population sizes are required to more accurately address this topic in the future.
