Bi-maxillary rehabilitation using the all-on-four method in patients with hypertension: case report and literature review

Objective: Cardiovascular diseases (CVD) are diseases of the circulatory system that affect the anatomy and pathophysiology of the heart and blood vessels; hypertension is one of the most common cardiovascular diseases. This case report aims to illustrate the implant survival rate and marginal bone loss in patients with hypertension undergoing fixed prosthetic rehabilitation, according to the all-on-four method, in both arches, at two years of follow-up. Materials and methods: The patient, suffering from hypertension, presented with severe diffuse periodontitis in both arches. Requiring a fixed rehabilitation, considering a more severe bone loss in the posterior maxillary and mandibular sectors, we opted for rehabilitation with a reduced number of implants according to the “All-on-Four” method. Follow-up visits were performed one week after surgery, after six months, and once a year for the following period (24 months). Any intra- and postoperative complications were noted so that the patient could be monitored. Every four months after surgery, hygiene maintenance sessions were carried out. Results: No implants were lost during the follow-up period, and no intra- and postoperative complications were recorded. Conclusion: By promoting reasonable blood pressure control, implant placement in patients with hypertension could be considered a predictable and safe procedure. Moreover, constant patient monitoring and adherence to a strict hygiene maintenance protocol could be crucial to promote implant survival
