Early Implant Failure in Patients Using Antihypertensive Medications: A Retrospective Cohort Study.
Article in International dental journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
INTRODUCTION AND
aimsAntihypertensive medications increase osteoblasts differentiation and bone mineral formation. Osseointegration of dental implants depends on new bone formation and remodelling. Consequently, improved osseointegration may be speculated in patients receiving antihypertensive drugs. Aim - Asses the effect of antihypertensive medications on osseointegration of dental implants.
methodsRetrospective cohort study. All individuals (792) who received at least one dental implant during a 6-year period at a single medical centre. The cohort was divided into three groups: normotensive (74.8% - 593) patients (NT group), hypertensive (23.4% - 185) patients using antihypertensive medications (HTN +med group), and hypertensive patients not using (1.8% - 14) antihypertensive medications (HTN -med group). Interventions-Installation of dental implants by experienced oral and maxillofacial surgeons with or without bone augmentation. Main measures - Early implant failure (EIF) (≤12 months from loading) reflects lack of new bone formation or excessive bone turnover during osseointegration.
resultsThe study included 792 individuals, 14 in the HTN-med group, 185 in the HTN +med group and 593 in the NT group. At the patient level, the HTN -med group were most likely (P = .041) to experience EIF 28.60% (4/14 patients). Due to the small sample of the HTN -med group, an additional analysis was carried out excluding this group. EIF of 9.70% (18/185 patients) in the HTN +med group was significantly (P = .047) lower than the NT group 14.50% (86/593 patients). 2971 implants were inserted in all study groups, 71.4% (2123) in the NT group, 26.4% (784) in the HTN +med group and 2.2% (64) in the HTN -med group. Collectively, EIF was recorded for 114 (3.84%) implants. In the HTN -med group, EIF of 6.25% (4 implants), was significantly (P < .001) higher than the two other groups. The EIF rate of the HTN +med group was 2.29% (18 implants) which was significantly less than that of the NT group 4.33% (92 implants). Controlling modifying parameters, using antihypertensive medication yielded lower EIF with marginal significance (P = .059) and OR = 0.618.
conclusionBased on statistically significant lower EIF rate found in the HTN +med group, antihypertensive medications may decrease the EIF rate of dental implants. CLINICAL RELEVANCE: Clinicians should be encouraged to treat hypertensive patients with implant-supported prostheses, provided patient compliance regarding medications intake is good.
