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.
