Pre-extraction alveolar buccal bone overbuilding: a preclinical investigation.

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
backgroundThe pre-extraction overbuilding procedure was designed aiming to mitigate buccal bone resorption following tooth extraction. The objective of this study was to compare the efficacy of pre-extraction and juxta-extraction buccal overbuilding treatments in preserving buccal bone volume following tooth extraction. MATERIAL AND
methodsAt the test sites (pre-extraction sites), an alveolar crest overbuilding was performed on the buccal aspect of the distal root of the fourth premolar using a xenograft covered with a collagen membrane. No treatment was applied at the control sites. After 3 months, the distal roots of both fourth premolars were extracted and the alveoli were filled with a collagenated xenograft. An overbuilt procedure was performed also at the control sites (juxta-extraction sites). After 3 months, biopsies were collected.
resultsConsidering the initial height difference between the lingual and buccal bone plates at the time of extraction, histological evaluation revealed that the resorption of the buccal bone relative to the lingual bone wall was 3.2 mm at the pre-extraction sites and 3.3 mm at the juxta-extraction sites. New bone originated from the residual pre-existing bone crest in an attempt to restore the original dimension.
conclusionThe buccal overbuilding procedures performed three months before tooth extraction did not contribute to preserve the buccal bone crest, despite necessitating an additional surgical procedure. Evidence of ongoing bone regeneration was observed within the augmented space maintained by the biomaterial, suggesting that a prolonged healing period, potentially exceeding six months as indicated by this study, might be required to achieve optimal outcomes.
