Odontogenic myxoma of the jaws is a rare benign odontogenic tumor. In this case, a 61-year-old male patient had a chief complaint about maxillary anterior gingival mass and excisional biopsy result confirmed odontogenic myxoma. The clear acrylic resin custom tray was designed to minimize displacement of flabby tissue which remained after the surgery. Neutral zone and external impression technique could provide satisfactory result in terms of denture stability and retention during jaw relation record and wax denture try-in procedure. This clinical report describes fabrication of complete dentures for a patient with odontogenic myxoma in regard to flabby tissue and neutral zone.

치성종양은 악구강계 영역의 질환 중 중요한 관심거리가 되어왔으며, 이중 상피성 치성종양에 관한 보고는 많으나, 중배엽성 치성종양에 관한 보고는 많이 이루어지지 않았다. 저자는 1975년부터 1985년까지 서울대학교병원 치과진료부에서 방사선학적, 병리학적으로 중배엽성 치성종양인 치성섬유종, 치성점액종, 백악질형성섬유종으로 진단된 증례들을 토대로 하여 연구, 분석한 결과 다음과 같은 결과를 얻었다. 1. 치성섬유종의 연령분포는 32세에서 72세로 광범위 하였으며, 발생위치는 모두 상악구치부이었고, 단방성이 2증례, 다방성이 1증례이었다. 2. 치성점액종의 연령분포는 40세에서 55세로 비교적 중년층에서 호발했고, 4증례가 상악에, 2증례가 하악에 발생하였다. 6증례 모두 방사선학적으로 다방성 방사선투과성을 보였으며, 경계는 비교적 불분명하였다. 3. 백악질형성섬유종은 주로 ?년에서 중년 성인 사이에 많이 발행하였고 40대에 가장 많은 출현율을 보였다. 남녀비는 약 1:2로 여자에게서 빈발하였다. 19증례중 하악에 15증례, 상악에 4증례가 발생하여, 하악이 호발부위였으며, 상하악 소구치, 대구치 부위에 발생하였다. 방사선학적으로 방사선투과성이 2증례, 혼합성이 12증례, 방사선불투과성이 5증례이었다.

Odontogenic myxoma is a rare tumor which occurs almost exclusively in the jaws, and seems to be of odontogenic origin. Clinically this tumor tends to appear in the second and third decades of life, and most of the lesions are located in the premolar - molar region. It is characterized grossly by mucoid or gelatinous gray-whitish tissue that replaces the cancellous bone and expands the cortex. It is invasive locally and has a high recurrence rate ranging from 10% to 33%. Radiographically, the appearance of this tumor is varied, but usually appears as a unilocular or multilocualr radioluscency of varying size. We experienced a rare case of odontogenic myxoma 12 years old patient related to mandibular bilateral impacted canines in the mandible, so we report this case with literature.

Odontogenic myxoma is a benign neoplasm composed of a uniform myxoid appearance that is believed to arise from the primitive mesenchymal portion of the tooth germ. It appears as painless swelling, but it should be distinguished from cystic lesion or other benign tumor. Although odontogenic myxoma is benign, its behavior is known to be aggressive and infiltrative, so thorough curettage and enucleation is necessary. We report a case of odontogenic myxoma of the mandible observed in our clinic with good prognosis after enucleation was done.

Odontogenic myxoma is one of rare tumors in oral and maxillofacial region and it is thought to be mesenchymal or ectomesenchymal origin. Its characteristics are benign and non-metastatic but it has the potential of local invasion and high recurrence rate. It originally occurs in atrium of heart and in central case, my xoma is located mainly in the maxilla and mandible. Most odontogenic myxoma develops in 2nd or 3rd decades of life and rarely occurs in child or older persons over fifty. The distribution of reported cases between the sexes is similar and the maxilla and mandible are equally affected or slightly higher in mandible. Clinically it is usually asymptomatic, however it can cause pain and paresthesia is complained in the advanced stages. Displacement and mobility of teeth have also been reported. Odontogenic myxoma is not a frequent tumor, but in case of slow and painless growing tumor it must be considered as a differential diagnosis.

In this report, a case is presented in which resected mandible was reconstructed immediately with vascularized bone graft and adjunctive implantation of osseointegrated dental implants. The primary was central odontogenic myxoma of mandible extending from symphysis to the left condylar neck. The hemimandibulectomy defect was restored with free fibular flap. Three months after 1st surgery, the transplant received five $IMZ^{(R)}$ implants. The masticatory function was restored with the implant borne denture. The result including facial appearance was very satisfactory.

Although odontogenic myxoma (OM) has various radiographic appearances, the characteristic features of OM are the multilocular radiolucent lesion, straight bony septa along the margin forming either square or triangular spaces. We present a case of OM in a 25-year old-male patient. Multilocular radiolucent lesion on the left mandible body showed tennis racket appearance. Cone beam computed tomography (CBCT) showed straight bony septa along the margin and cortical perforation. This CBCT features would have significantly contributed to allowing a diagnosis of OM. We think that this case shows characteristic radiographic features of odontogenic myxoma.

Squamous cell carcinoma is the most common type of oral cancer and odontogenic myxoma is relatively uncommon benign tumor of mesenchymal origin. There are, to our knowledge, no prior reports of simultaneously occurring squamous cell carcinoma and odontogenic myxoma of the jaw bones. In this case, at first, the plain films and computed tomograms revealed a large expansile multilocular radiolucent lesion on left mandible and marked expansion of cortical plate. In addition this radiograms revealed also infiltrative bony destruction of anterior and medial border of ascending ramus of left mandible and alveolar bone of left maxilla, floating teeth on left lower molar area and metastatic enlargement of left submandibular, jugular digastric and spinal accessory lymphnodes. Magnetic resonance imaging of this patient revealed infiltrative growth of tumor on alveolar bone of left maxilla, left retromolar fat pad. left masseter and left medial pterygoid muscle. Intraoral presurgical biopsy presented typical features of squamous cell carcinoma. After chemotherapy with radiation therapy during 6 months. this central lesion was diagnosed as odontogenic myxoma by the postsurgical biopsy. After 3 months, this patient presented multiple metastatic signs at lumbar spines, rib and liver. Consequently, our case is simultaneous occurrence of squamous cell carcinoma and odontogenic myxoma.

Odontogenic myxoma, a rare tumour that occurs in the jaws, locally invasive, destructive tumors that do not metastasize to lymph nodes. Large odontogenic myxoma on mandible is treated by mandibulectomy, defected mandible is reconstructed by bone graft. Reconstructed mandible is difficult to reconstruct dentition using implant because of deficiency of bone amount. So it is necessary to additional bone graft. But a poor aspect of soft tissue lead to unsatisfactory result. Because of distraction osteogenesis is possible to reconstruction of an amount of bone and soft tissue, that is advantage to reconstruction of alveolar bone on reconstructed mandible. We report with review of literatures the 25 years old male patient who had odontogenic myxoma in left mandible, was undergone mandibulectomy and successfully implant installation and prosthetic restoration after distraction osteogenesis(Track $Plus^{(R)}$, KLS Martin, Germany) on the reconstructed mandible with a free iliac bone graft, and we have conservative and successful result.
