Gingival fibromatosis is a relatively rare condition of gingival hyperplasia and seldom accompanied with bony changes. We present a case of gingival fibromatosis with deformed alveolar bone in a 35-year-old woman. Gingival hyperplasia and significant displacement of the remaining carious teeth had spoiled her appearance. In the molar region, a decayed crown had resulted in loss of teeth contacts leading to interjawal contact by the hyperplastic maxillary and mandibular ridges. To improve her appearance and restore masticatory function, we planned surgery which consisted of extraction of all remaining teeth, gingivectomy and selective alveolectomy in one operation. Since it was difficult to re-shape the alveolar ridge, surgical templates （STs） and immediate dento-maxillary prostheses were fabricated preoperatively, which were based on precise model prediction. The use of STs during the operation helped to maintain the preoperative position of the jaw and to operate quickly and easily. Immediate dentures were fixed with circumferential wiring for 3 weeks. Seven years have passed postoperatively, and the patient is contented with her appearance and masticates well with dentures.
