The Effect of Common Local and Systemic Conditions on Dental Implant Osseointegration: A Review of Literature

Context: Although dental implant (DI) is an increasingly prevalent therapeutic approach in partial or complete edentulous patients, understanding the bone healing mechanisms and effective factors on it, is still necessary for us. The initial requirement in DI success rate is to achieve a proper wound healing, DI stability and desirable osseointegration, Thereby, assessment of all probable risk factors of DI treatment should be considered prior to a treatment plan. Evidence Acquisition: Literature searching was performed through electronic search in three data bases of MEDLINE, Google scholar and SCOPUS, and also manual search on available performed studies up to June 2013. Results: Though, there are multiple technique-related or patient-related local and systemic factors, which may interfere with proper osseointegration or compromise the long-term implant prognosis. There are just few absolute contraindications for DI therapy such as IV bisphosphonate therapy and severe renal failure. Conclusions: There are few absolute contraindications for DI treatment. As a whole, correct patient selection, and applying standard rules of surgical procedure and DI loading would lead to a successful DI treatment.
