Acquired Ankyloblepharon Correction Using Ocular Surface and Tarsal Mucous Membrane Grafting in Cicatrizing Ocular Surface Diseases.

Purpose: To report the long-term surgical outcomes of acquired ankyloblepharon correction using mucous membrane graft.

Methods: Five eyes of 4 patients (median age, 19 years) with acquired ankyloblepharon were managed using eyelid splitting and mucous membrane graft anchored to the recti muscles on the bulbar surface in the respective quadrant and onto the bare tarsal surface. Outcome measures include a change in the palpebral fissure width, ability to fit scleral contact lenses, visual acuity, and cosmesis.

Peri-implant bone regeneration in pigs.

Purpose: To review the current literature to answer the focused question: in the experimental pig model (population), which types of peri-implant bone defects (exposure) have been used evaluate different modes of therapy and what is their capacity for spontaneous healing and regeneration (outcome)?

Methods: Following PRISMA guidelines, electronic databases were searched for studies reporting peri-implant bone defects in the maxillae or mandibles of pigs. Those studies which reported a control group of untreated defects with assessment of spontaneous regeneration [new bone area (BA)] and/or re-osseointegration [new bone-to-implant contact (BIC)] via quantitative radiography or histomorphometry were included in a random effects meta-analysis for the outcomes BA and BIC.

Results: Overall, 21 studies, mostly performed in the mandibles of minipigs, were included.

Proteomic Analysis of Human Serum Proteins Adsorbed onto Collagen Barrier Membranes.

Collagen barrier membranes are frequently used in guided tissue and bone regeneration. The aim of this study was to analyze the signature of human serum proteins adsorbed onto collagen membranes using a novel protein extraction method combined with mass spectrometry. Native porcine-derived collagen membranes (Geistlich Bio-Gide, Wolhusen, Switzerland) were exposed to pooled human serum in vitro and, after thorough washing, subjected to protein extraction either in conjunction with protein enrichment or via a conventional surfactant-based method.

Digital precision meets dentin preservation: PriciGuide™ system for guided access opening.

Traumatic injuries to maxillary central incisors often necessitate root canal treatment (RCT). However, traditional access cavity preparation can remove significant dentin, compromising tooth strength and long-term prognosis. This article explores the use of the PriciGuide™ system for minimally invasive access cavity preparation in such cases.
