BACKGROUND The reconstruction of a large mandibular defect poses a challenging issue in oral cancer ablation surgery. One popular option for mandibular continuity reconstruction after tumor resection involves the use of a reconstruction plate (R-plate), which maintains space and contour without bone harvesting. An R-plate, however, cannot provide final functional loading rehabilitation with imp...

The vascularized fibular flap is one of the standard treatment choices for the reconstruction of the mandible; however, the consequences of condylar restoration have not previously been reported. The use of three-dimensional models allows for a more predictable reconstruction. The purpose of the present study was to assess the outcome of stereolithographic model-assisted reconstruction of the m...

The central giant cell granuloma (CGCG) is benign, nonodontogenic, and intraosseous lesion of the jaw. Aggressive subtypes of CGCG have a tendency to recur after excision and require wide resection that leads to major defects in the jaw. In this case report a patient who had severe mandibular bony deficiency as a result of excision of aggressive CGCG, orthodontic, and prosthetic treatment was d...

Oral lichen planus (OLP) is an immune-mediated mucocutaneous disease associated with an increased risk in oral squamous cell carcinoma (OSCC). Nearly all cases of malignant transformation have been reported in patients >40 years old. We report the case of a 37-year-old woman with a 5-year history of erosive OLP who presented with malignant transformation to OSCC. Delineating the margins of the ...

Effectiveness of bone engineering by cell sheet technology to repair canine mandibular injuries was investigated. Cell sheets were produced from canine stem cells cultured by density gradient centrifugation and osteoblast induction. A scaffold surface of polylactic-co-glycolic acid (PLGA) copolymer was wrapped with cell sheets. Mandibular injuries were created in 12 healthy dogs followed by imp...

Gingival recession is one of the most common soft tissue problems, especially when it hinders the esthetics of a patient. Gingival recession can further lead to root caries, sensitivity, and difficulty in plaque control. Moreover, exposed roots are prone to abrasion and erosion. Periodontal plastic surgery is one of the emerging fields, which helps to meet such soft tissue problems. Currently, ...

PURPOSE In this 10-year longitudinal study we evaluated the amount of mandibular residual ridge resorption for 2 groups of subjects with complete dentures, one group with porcelain artificial teeth and the other with acrylic resin teeth. METHODS One hundred and nine patients who had undergone ridge extension procedures with skin graft and prosthetic rehabilitation with porcelain or acrylic re...

Reconstruction of bone is often required for large bone defects and also in cases of impaired bone regeneration. Vascularized bone transfer has been widely used for reconstruction, especially for segmental mandibular defects, and for reconstruction of long bones of the upper limb and lower limb after trauma or after significant bone resection for tumour. It has also been used in cases of scapho...

The aim of the report is to document 15-month results of mucogingival surgery applied following intentional replantation (IntR). A mandibular left lateral incisor with severe periodontitis and malposition was replanted and splinted following root canal treatment. Three months after IntR, a free gingival graft (FGG) was placed. Fifteen months follow-up of the case demonstrated significant improv...

Experience with 9 patients who underwent mandibular reconstruction with autogenous free bone grafts and subsequent placement of titanium screw-type implants is reported. The interval between bone grafting and implant placement in these patients ranged from 8 to 34 months. A total of 33 implants was placed, followed up for 16 to 53 months, and achieved an 85% survival rate. Analysis of these pat...
