Prosthodontic treatment for patients with large mandibular defects; porous hydroxyapatite grafts.

It is difficult for both prosthodontists and their patients with large marginal defects to achieve a satisfactory prosthodontic result, because retention, support, and stability of the prosthesis are limited and recovery of esthetics is unsatisfactory owing to large mandibular defects. Alveolar ridge augmentation therapy is performed to compensate for such problems. We have experienced a good prognosis of prosthodontic treatment for over 10 years in two patients with large marginal defects of the partially edentulous mandible, who had undergone grafting of porous hydroxyapatite blocks to their bone defects. It has been reported that porous hydroxyapatite blocks are unsuitable for edentulous patients, because the mucosa covering the hydroxyapatite block is too thin and delicate to support dentures. We, therefore, designed the denture to prevent concentration of occlusal stress on the mucosa. In both of these two cases, we achieved recovery of occlusal function and esthetics by affixing denture to the large marginally resected defect augmented with a graft of porous hydroxyapatite block.

[Retrospective analysis of 30 cases of mandibular ameloblastoma operated in the Ivory coast from 1992 to 2000].

OBJECTIVE: We analyzed a retrospective series of 30 cases of ameloblastoma operated in the Ivory coast from 1992 to 2000. PATIENTS AND METHODS: The following techniques were used--temporary reconstructions via the endobuccal approach using a Peri prothesis in 27 cases and a resin coated Peri prosthesis in one;-- definitive reconstructions using iliac bone grafts in 3 cases and rib grafts in 14. These reconstructions were performed in a second operation via a cutaneous approach to replace the Peri prosthesis. Thirteen patients were lost to follow-up for this second phase. Mean follow-up ranged from 6 months to 13 months (mean 9.9 months). RESULTS: Satisfactory outcome was acchevied when mouth opening was greater than 10 mm and patients with an acceptable cosmetic result no longer complained of mastication or phonation problems. There were four postoperative infections after bone graft reconstruction (two of them were immediate reconstruction). The resin coated Peri prosthesis led to a skin ulceration. DISCUSSION: This study demonstrated the interest of mandibular reconstruction in undermedicalized countries where indications are dominated by reconstruction after resection for ameloblastoma. The large number of patients lost to follow-up before the second stage bone grafts points out the need for immediate reconstruction using autologous bone. Further study in a larger series would be needed to determine the cause of failure after immediate reconstruction.

Use of acrylic of low polymerization after heminandibulectomy.

Two cases of mandibular reconstruction are presented in which a premolded prosthesis of acrylic of low polymerization covered by silicone rubber was used. We believe that the good results obtained were not only due to the material used, but also because the periosteum and meniscus were preserved in the joint space.

Benign lower jaw tumours and their management: a ten year experience in Nigeria.

Lower jaw tumours in Nigeria often grow to enormous size. A high cure rate can be achieved by wide excision of the tumours and bone grafting. Of 23 patients who underwent mandibular reconstruction in Enugu, Nigeria, over a ten year period, loss of bone graft occurred in three patients (14.28%), but no recurrence of tumour was noted over a follow-up period ranging from 2-12 years. An acceptable aesthetic and functional result followed bone grafting in most cases.

Mandibular guidance prostheses following resection procedures: three case reports.

Unilateral loss of mandibular continuity creates problems in prosthetic reconstruction. For dentate patients, palatal guide ramps or mandibular guide flange prostheses are indicated. Edentulous patients are much more difficult to retrain in mandibular movements, but complete dentures designed with stabilising occlusal contacts can be successful in compensating for the deviation. Three case reports are presented.

The prosthetically guided osteodistraction of the mandible in the microvascular bone reconstruction after cancer surgery.

The rehabilitation of the mandible after ablation cancer surgery is a challenge. Furthermore, osteodistraction in the microvascular fibula flap makes it difficult to predict adequate bone lengthening. The aim of this article is to evaluate a protocol used to manufacture templates for measuring osteodistraction, in terms of force vectors and definitive height. An accurate prosthetic wax-up with guide pins measuring the quantity of bone lengthening must be performed to manufacture the template. This device may be used to establish the end of the osteo-distraction in respect to the vertical dimension of the definitive occlusion.

Dental restoration with endosseous implants after mandibular reconstruction using a fibula free flap and TMJ prosthesis: a patient report.

This patient report describes the secondary reconstruction of a hemimandibular and condylar defect and the dental restoration of a 56-year-old woman who had been subjected to radical ablative surgery 30 years earlier to remove a tumor. In the first phase, a fibula free flap was used in combination with a total TMJ prosthesis for the reconstruction of the hemimandible and condyle. Secondly, 3 endosseous implants were placed in the residual mandible. These implants were used to support an overdenture prosthesis that has remained in continuous function for a period of 2 years.

[Resection prosthetics for free bone transplantation. Prerequisites for establishing a bone transplantation concept of the mandible].

The present paper examines the development of dental and surgical methods for the reconstruction of bone defects in the lower jaw. Starting with the resection-prosthesis we highlight important stages of bone transplantation in the lower jaw. Until 1914, actually no concept existed for reconstruction of continuity in the lower jaw. Only when dentists and surgeons started working together in the First World War, a bone-transplantation concept for the lower jaw could be elaborated.

Prosthetic plate mandibular reconstruction.

The head and neck surgeon may choose one of several available methods to reconstruct the mandible following tumor ablation. This article discusses the use of metallic mandibular prostheses, the indications for alloplastic mandibular reconstruction, techniques of plate application (AO and THRP), and associated complications.

[Anaesthesia and spontaneous return of sensation following resection of the mandibular continuity with primary alloplastic materials].

Resection affecting the continuity of the mandible and the mandible nerve leads to complete anaesthesia of the lower lip and mental area, furthermore to deformity and functional disturbance like uncontrolled salivation. In our long term follow up study on multimodal neurological investigation sensibility is reported to have uncomplete regenerated spontaneously often already after one year. Complete sensory, however, could not be found; the incomplete sensory return was to be measured in individually different degrees of hypaesthesia. Furthermore the axonal qualities of the mandible nerve show different regenerative potential: the receptor function for pressure and contact sensitivity could be demonstrated in the most of cases, whereas the heat- and painreceptor qualities could not be revealed in all cases.

"Planned" management of squamous cell carcinoma of the mandibular oropharynx.

The term "planned," where management of squamous cell carcinoma of the mandibular oropharynx is concerned, has been put into proper perspective with several case examples in order to clarify its relationship to the pathophysiology of the disease and the anticipated morbidity involved in its cure.

[Resection of metastatic pulmonary lesion of osteosarcoma extended into the left atrium and ventricle via the pulmonary vein].

A 35-year-old woman had underwent an amputation of the right hemimandibula for an osteosarcoma. Twenty months after the operation, she was admitted to our hospital with complaints of syncope. On chest computed tomography and echocardiography, an atrial tumor was disclosed, which extended from the lesion of the left pulmonary lower lobe. This tumor intravascularly developed through the left inferior pulmonary vein. The intracardiac tumor was resected through left atriotomy under cardiopulmonary bypass, and immediately after weaning of bypass left lower lobe was resected. On pathological study the tumor was diagnosed as metastasis of osteosarcoma. Despite postoperative chemotherapy including CDDP, she died of metastasis in pulmonary, adrenal gland and liver 12 months after the second operation.

[Prosthesis in mandibulectomized patients].

The most frequent options currently available for rehabilitation of patients requiring mandibular resection, are discussed. Accordingly, prostheses are designed depending on the surgical technique employed. The most common characteristics of the oral cavity are reviewed, as well as their involvement in mandibulectomized patients. Finally, the relationship that should exist between maxillofacial prostheses and the stomatological cares required by patients who are candidates for radio and/or chemotherapy is stressed.
