Abstract
OBJECTIVE: The aim of the present systematic review was to assess the efficacy of parathyroid hormone supplementation on the osseointegration of implants. METHODS: The addressed focused question was Does parathyroid hormone supplementation affect osseointegration around implants? Indexed databases were searched from 1965 up to and including April 2015 using various key words including: Bone to implant contact; implant; parathyroid hormone; and osseointegration. Letters to the Editor, case-reports/case-series, historic reviews, commentaries and articles published in languages other than English were excluded. The pattern of the present systematic review was customized to primarily summarize the pertinent data. RESULTS: Eighteen studies fulfilled the eligibility criteria. Evidence was limited to preclinical animal studies only (11 studies in rodents, 4 in dogs and 3 in rabbits). Number of titanium implants placed ranged between 20 and 80 implants. Results from 16 studies showed that PTH supplementation enhanced new bone formation and/or BIC around implants. One study suggests that PTH-coated implants improve BIC and BA. One study showed no significant difference in BIC and new bone formation around implants with PTH hydrogel placement. CONCLUSION: Efficacy of PTH supplementation on osseointegration of implants shows promising results in animal models, however further investigation is necessary to assess the effectiveness in humans.
