Oral rehabilitation with dental implants in patients with tooth agenesis: a retrospective study in Helsinki University Hospital, Helsinki, Finland.
Article in Acta odontologica Scandinavica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThe aims of this retrospective and descriptive study were to investigate oral rehabilitation with dental implants in tooth agenesis patients treated at Helsinki University Hospital, Finland, between 2015 and 2019, and to analyze implant survival and prosthetic complications within the first 2 years. Material and methods: This study included 72 patients (42 oligodontia and 30 hypodontia). Data concerning general/oral health and implant treatment modalities were retrieved from hospital records. Results: Patients were mostly systemically healthy nonsmokers with a mean age of 32.3 years at the time of implant placement. Orthodontic treatment was required for 77.7%, and 31.9% underwent also orthognathic surgery. Patients had 6.6 missing teeth on average and received 2.8 implants each, 205 in total. Tissue augmentation was needed in 64.4% of cases. Screw-retained suprastructures, mainly single crowns (76.4%), were used in 95.5% of cases, all with custom abutments. The mean follow-up time was 25.2 months, with one technical and one mechanical complication. No implants were lost.
conclusionsWith multidisciplinary planning and collaboration, replacement of all teeth in tooth agenesis may not be required. In this study, despite an average of 6.6 missing teeth per patient, only 2.8 implants were placed on average.
