Long term assessment of root coverage stability using connective tissue graft with or without an epithelial collar for gingival recession treatment. A 12-year follow-up from a randomized clinical trial.

Aim: To evaluate the long term root coverage outcomes of coronally advanced flap plus a connective tissue graft with (CAF + CTG) or without an epithelial collar (CAF + ECTG), and evaluate the adjacent treated sites included in the flap.

Methods: Seventeen of the original 20 subjects included in the randomized clinical trial were available at 12 years (43 sites). Mean root coverage (mRC), keratinized tissue width (KTW), gingival thickness (GT) on the grafted and adjacent sites were evaluated and compared with baseline and 6 months.

Significance of the epithelial collar on the subepithelial connective tissue graft.

Background: Most clinicians adopt two versions of the subepithelial connective tissue graft (SCTG) procedure, SCTG with or without the epithelial collar on the graft combined with a coronally advanced flap (CAF). However, limited evidence is available to determine whether a retained epithelial collar on an SCTG is needed for a better outcome. The goal of this study was to compare the clinical outcomes of the two SCTG techniques (i.

Sandwich bone augmentation using recombinant human platelet-derived growth factor and beta-tricalcium phosphate alloplast: case report.

This report presents a case of reconstructing and augmenting a buccal fenestration defect associated with simultaneous implant placement using recombinant human platelet-derived growth factor BB (rhPDGF-BB) combined with the synthetic alloplast beta-tricalcium phosphate (beta-TCP) and collagen membrane. Fenestration and fracture of the labial plate occurred at the time of implant placement at the maxillary left lateral incisor position. The sandwich bone augmentation technique was applied using autogenous bone as the inner grafting material and rhPDGF-BB + beta-TCP as the outer grafting material.

Flapless implant surgery in the esthetic region: advantages and precautions.

Because osseointegration is now considered highly predictable, the current trend is to develop techniques that can provide function, esthetics, and comfort with a minimally invasive surgical approach. To achieve those goals, flapless implant surgery using a tissue punch technique has been suggested. This paper presents two clinical cases of single-tooth implants placed in the esthetic region (anterior maxilla), which illustrate systematic approaches to flapless implant surgery for immediate and delayed loading protocol.
