ABSTRACT
Since the inception of implant dentistry, implant-supported metal-acrylic resin hybrid prostheses are the major prostheticdevices given to restore physiological and esthetic functions of oral tissues of edentulous or partially edentulous patients. Theclinical performance of the most commonly used acrylic resin in the fabrication of dentures, namely, polymethyl methacrylate(PMMA) resin determines its long-term deformation and wear resistance. However, its poor mechanical resistance to wearand tear poses a major setback. An attempt to incorporate graphene derivative with PMMA resin in prosthesis fabrication hasdemonstrated significant improvement in the mechanical strength as per literature. This case report presents rehabilitation ofedentulous mandibular jaw and also briefly states the properties of graphene and the polymerization process of the resin withthe graphene derivative.
ABSTRACT
Patients with head and neck cancer face high morbidity due to the disease and its treatment and are affected on a variety of personal and physical levels. Maxillofacial prosthetics offer support for other disciplines in a multidisciplinary setting; can help to prevent / minimize the sequelae from disease and treatment, and offers the patient help in the rehabilitation process. Maxillofacial prosthodontics focuses on optimizing the disrupted rudimentary function of individuals whose rehabilitation will be a lifelong proposition. Normal function may not be achieved but optimal function should always be achieved and the patients can lead a near to normal life.

Maxillary obturator prosthesis is the most frequent treatment option for management of partial or total maxillectomy. Heavy weight of the obturators is often a dislocating factor. Hollowing the prosthesis to reduce its weight is the well established fact. The alternate technique to hollow-out the prosthesis has been described in this article which is a variation of previously described processing techniques. A pre-shaped wax-bolus was incorporated inside the flasks during packing of the heat-polymerized acrylic resin to automatically create the hollow space. The processing technique described is a single step flasking procedure to construct a closed-hollow-obturator prosthesis as a single unit. To best understand the technique, this article describes management of a patient who had undergone partial maxillectomy secondary to squamous cell carcinoma rehabilitated with a hollow-obturator prosthesis.

Objective. The aim of this study was to evaluate tooth loss prevalence, denture types and prosthetic dental treatment needs among people of ages 35-44 of Bayangol District of Ulaanbaatar City. Materials and Methods 9351 subjects were examined and questionnaires were presented to partially and/ or totally edentulous subjects among patients of this research. The questionnaire consisted of questions; age, gender, education level, place of residence, problems with dentures, necessity for new denture. Results. Most of the people were partially edentulous (93.0%) and 6.0% was full dentate, 1.0% was complete edentulous. In this research, only 6% of the people are full dentate but 94.3% have missing teeth and it indicates that the most of the people are demanding partial denture treatment. Acrilic denture was consumed in (3159) 95.0% of total dental coverage, but only 116 people had fixed denture. Acrylic denture was consumed much more than removable partial denture and bridge, and it may be due to expensive price of bridge and implant. The number of female patients with complete dentures was more than the number of males, with opposing trend for partial dentures. Tooth loss is a major indicator of oral health among adults, which may be increased by the lack of access to care, certain chronic diseases and/or insurance status. Conclusions. Almost 940 people in each 1000 people of ages 35-44 or 9 of every 10 subjects of among patients of Bayangol District, Ulaanbaatar City have edentulism /р>0.001/. It has been estimated that 34.5% about adults of those with edentulism had prosthetic treatment and majority (95%) of them use acrylic denture. We can see that 94.3% of subjects among the patients of ages 35-44 in our research have had missing teeth and 60% of them had no any treatment and are demanding prosthetic treatment.
