Sinus Lift-Before-Extraction Approach: Our Experience With a Strategic Approach to Implant Site Development.
Article in Cureus, 2026. 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
objectivesTo present a sinus lift-before-extraction staged approach for maxillary sinus augmentation in patients with posterior maxillary teeth of poor or hopeless prognosis. In this protocol, lateral sinus augmentation is performed before tooth extraction and implant placement to increase available bone height for subsequent rehabilitation. METHOD AND MATERIALS: This retrospective case series included 16 posterior maxillary sites in 13 patients treated over an eight-year period. All cases required lateral window sinus augmentation in regions with compromised teeth planned for future extraction and implant-supported rehabilitation. Preoperative cone-beam computed tomography demonstrated a mean residual bone height of 4 mm. Following augmentation, the non-restorable teeth were temporarily retained during healing to support provisional restorations and maintain function and esthetics. Tooth extraction and implant placement were then performed as a second-stage procedure.
resultsBetween 2014 and 2022, sinus augmentation was performed as the initial stage in 13 patients (43-69 years). Healing was uneventful, and morbidity was minimal. At the second stage, the compromised teeth were extracted, and 39 implants were placed in the augmented sites. All implants achieved osseointegration and were restored with fixed implant-supported prostheses. The mean follow-up was 60 months. Patient-reported satisfaction was favorable.
conclusionA sinus lift-before-extraction staged approach appears to be a feasible approach with favorable clinical, radiographic, and patient-reported outcomes in selected posterior maxillary sites associated with hopeless teeth. Temporarily retaining the teeth during healing may help preserve interim function and esthetics while enabling implant placement after augmentation.
