Except for special situations, it is generally agreed that best results in the treatment of facial fractures is expected if reduction is done within the first 2 or 3 weeks after injury. We reduced facial bone fractures at 4 to 7 weeks after trauma. A 44-year-old female patient underwent open reduction for her right zygomaticomaxillary complex fracture at 7 weeks after injury. A 59-year-old female patient underwent surgery for the right mandible body and left parasymphysis fractures at 4 weeks after injury. Using traditional approaches, granulation tissue and callus were removed from the fracture sites, and malunited fracture lines were separated by a small osteotome. We reduced the displaced fractured zygoma and mandible to their normal anatomical positions and fixed them using titanium plates. No complications such as asymmetry, malunion, malocclusion, or trismus were seen. Unfavorable asymmetric facial contours were corrected, and we obtained good occlusion with favorable bony alignment. The functional and aesthetic outcomes were satisfactory. Through removal the callus and limited osteotomy, a successful approach to the previously fractured line was possible, and an exact correction with symmetry was obtained. This method can be a good option for obtaining good mobility and clinical results in treating delayed facial bone fractures.

After periodontal surgery, the potential healing responses were occurred by interaction among junctional epithelium, gingival connective tissue, alveolar bone and periodontal ligament. The only cell that created periodontal regeneration was derived from periodontal ligament. The aim of the study was to evaluate the regenerative effects of the collagen membrane($collacote^{\circ}C$) and autogenous connective tissure graft with periosteum. Experimental periodontitis were created in furcation area of 4 adult dogs with bone removal and gutta percha packing. After 6 weeks later, the gutta percha was removed and experiment was performed divided by 3 groups. 1) Flap operation(control group). 2) Flap operation with collage membrane(Experimental group I). 3) Flap operation with autogenous connective tissue graft with periosteum (Experimental group II). After dogs were sacrificed after two and three weeks, specimens were prepared and stained with hematoxylin-eosin and masson-trichrome stain for light microscopic study. The results were as follows : 1. In all gruoups, connective tissue compartments were increased from two to three weeks especially in experimental group I. 2. Collagen membrane and connective tissue were increased collagen deposits of periodontal ligament. Therefore collagen fiber attached to tooth surface was seen. 3. In al experimental groups, newly forming alveolar bone was seen. 4. Collagen membrane and connective tissue were which prevented proliferation of epithelium, aided connective tissue new attachment and influenced periodontal regeneration.
