Fig. 6From: Early bone formation around immediately placed two-piece tissue-level zirconia implants with a modified surface: an experimental study in the miniature pig mandibleLM micrographs revealing the buccal peri-implant mucosa after 8 weeks. a Note the intimately adherent junctional epithelium (JE) and its apical end (aJE). b Higher magnification of a. Note the keratinized oral epithelium (OE) and the non-keratinized junctional epithelium (JE). c Note the collagenous fibers (black arrows) in the peri-implant connective tissue running parallel to the implant surface.
