Neutral zone or conventional implant-retained overdentures? an assessment on quality of life, denture stability, patient satisfaction and maintenance requirements.
Article in BMC oral health, 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
purposeThis study evaluated whether implant-retained overdentures fabricated using the neutral zone (NZ) technique offer superior long-term oral health related quality of life (OHRQoL) outcomes compared to conventional overdentures (CO) and assess the influence of these techniques on denture stability, patient satisfaction, and maintenance requirements. MATERIALS AND
methodsThis study involved 29 edentulous patients (14 in the NZ group and 15 in the CO group) who received mandibular implant-retained overdentures with a minimum two year follow up. Two implants were placed in the mandible for each patient, and overdentures were fabricated using either conventional methods or the neutral zone concept, all performed by the same clinician and technician. The OHIP-EDENT questionnaire assessed functional, physical, psychological, and social aspects. Statistical analyses compared pre and post treatment scores as well as intergroup differences.
resultsBoth groups demonstrated significant post-treatment improvement in OHRQoL (p < 0.001). However, no statistically significant difference was observed between the NZ and conventional groups in overall satisfaction, functional outcomes, pain reduction, or psychological and social well-being (p > 0.05). Furthermore, no significant difference was found in prosthesis fracture rates or the frequency of locator replacements (p > 0.05).
conclusionsImplant-retained overdentures, regardless of fabrication technique, significantly improved patient reported outcomes. However, the NZ technique did not provide a significant advantage over the conventional technique in long term OHRQoL or prosthodontic maintenance.
