Complication rates of guided bone regeneration using titanium-reinforced PTFE membranes: a retrospective analysis.
Article in Clinical oral investigations, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionThis study analyzed complication rates of guided bone regeneration (GBR) using titanium-reinforced polytetrafluoroethylene (PTFE) membranes for alveolar ridge augmentation. MATERIAL AND
methods84 patients treated with GBR using titanium-reinforced PTFE membranes (91 sites) were retrospectively analyzed. Complications such as membrane exposure and early removal were analyzed concerning patient age, defect site position, size, simultaneous vs. two-stage implant placement, smoking, and the use of bone grafts (BG) and substitutes (BS).
resultsEarly removal due to membrane exposure was necessary in 14/91 sites (15.4%). No correlation was found between early removal and patient age (p = 0.917). Analyzing early removal between the upper and lower jaw and between both jaws' anterior and posterior tooth regions revealed no correlations (p = 0.381 and 0.477, respectively). Defect sites sizes of 5-6 mm exhibited the highest rate of membrane exposure, requiring early removal, accounting for 57.1% of these sites (8/14). No correlation was observed between the defect sites size and early removal (p = 0.660). Comparison of simultaneous (74 sites) vs. two-stage implant placement (16 sites) showed no correlation with early removal (p = 0.706). Membrane exposure incidence was 42.9% among smokers (27 patients, 32.1%) and 57.1% among non-smokers (57 patients, 67.9%), without correlation. No correlation was found between the type of BG and BS and early removal (p = 0.500).
conclusionGBR using titanium-reinforced PTFE membranes is effective for alveolar ridge augmentation and has favorable long-term outcomes. CLINICAL RELEVANCE: Careful surgical technique and postoperative care can minimize the notable risk of PTFE membrane exposure.
