BackgroundVarious medical conditions and the drugs used to treat them have been shown to impede or complicate dental implant surgery. It is crucial to carefully monitor the medical status and potential post‐operative complications of patients with systemic diseases, particularly elderly patients, to minimize the risk of health complications that may arise.AimThe purpose of this study was to review the existing evidence on the viability of dental implants in patients with systemic diseases and to provide practical recommendations to achieve the best possible results in the corresponding patient population.MethodsThe information for our study was compiled using data from PubMed, Scopus, Web of Science and Google Scholar databases and searched separately for each systemic disease included in our work until October 2023. An additional manual search was also performed to increase the search sensitivity. Only English‐language publications were included and assessed according to titles, abstracts and full texts.ResultsIn total, 6784 studies were found. After checking for duplicates and full‐text availability, screening for the inclusion criteria and manually searching reference lists, 570 articles remained to be considered in this study.ConclusionIn treating patients with systemic conditions, the cost–benefit analysis should consider the patient's quality of life and expected lifespan. The success of dental implants depends heavily on ensuring appropriate maintenance therapy, ideal oral hygiene standards, no smoking and avoiding other risk factors. Indications and contraindications for dental implants in cases of systemic diseases are yet to be more understood; broader and hardcore research needs to be done for a guideline foundation.
