ABSTRACT
Nylon-derived flexible dentures are an excellent alternative to conventional way of treating microstomia. Thermoplastic resins not only provides excellent comfort and aesthetics but also adapt to the constant flexibility during insertion and removal of dentures in restricted mouth opening cases.This case report discusses the successful management of a patient with microstomia due to surgical excision and radiotherapy with thermoplastic flexible dentures

Rest or vertical stops are not required for flexible dentures because on functional loading they would flex and distribute the stress to the underlying tissues3,4. Insertion and removal of this flexible denture is very easy compared to other means of attachments in sectional dentures in patients with limited mouth opening . The patient reported with the marked improvement in mastication as he was able to chew his food properly .The patient was also satisfied with the esthetics and light weight of the prosthesis. Even though these thermoplastic resin materials have disadvantages like require special instruments for adjustments, repairing is difficult , needs atleast 4mm of interoccusal space for adequate retention of teeth to the denture base and technique sensitive , the flexible denture has provided a simple and effective treatment solution for this patient3, 6

As a dental nurse at the Eastman Dental Hospital I was fortunate enough to have the opportunity to work with dental hygienists in the preventative management of head and neck cancer patients, ensuring long term oral health of the dentition and preventing unwanted effects of tooth loss after radiotherapy. Inspired by this experience and with a strong desire to help others, I decided to pursue a career in dental hygiene and therapy to make a difference in people's lives through oral health care.
Dentures are removable appliances that can replace missing teeth and help restore a patient’s smile. There are many steps involved in providing dentures. Firstly, patients must schedule an appointment at the dental office. Patients
So here we go for an advanced technique of implanting which provides a more secure and stable denture. Most people prefer to get replaced with the permanent teeth. For those people, we move on with their desire using a technique called as a hybrid denture. It consists of dentures that are fixed onto implants with a full set of high-quality prosthetics to replace full rows of teeth.

Implant overdentures have contraindications, mainly in relative to the risks related to the surgical procedures, even if in specific cases it can be regarded as a minimally invasive one. Additionally, using this specific treatment concept is limited to cases with reduced prosthetic vertical space that makes it impossible to apply the attachment systems and also provide adequate prosthesis resistance (e.g., using Locators requires a minimum of 8.5mm vertical space and 9mm horizontal space; bar attachments require 10 to12 mm vertical space) .Implant overdentures are not recommended when there is a decreased D4 bone density, in bruxism and in severe oral hygiene deficiency.
Alice stated that she does not wear her dentures because they do not fit well. The dentist can assess her periodontium and readjust her partial dentures.
The importance of the teeth is nothing new to be described as these plays an inevitable role in our life. All of us understand the need and the advantage of having healthy teeth throughout our life. The dentures and the implants are the excellent examples to teach us the usefulness of the original teeth. There are several complications that are related with the oral and dental health that tend us to seek the services from a dentist. The broken crown is one of these complications that require intervention from the dentists. The crowns are usually found to be intact for lifetime but in some cases, these may become broken or get chipped due to different reasons. In these conditions, we need to see the dentist for an appropriate cure.
Initially, for the purpose of denture base, vulcanized rubber (vulcanite) has been in use. It was introduced in the year 1855 to the field of dentistry (Tandon et al., 2010). However, there were several issues faced with respect to its fabrication as well as the aesthetics. With this, the year 1937 saw the advent of PMMA which replaced vulcanite as it had enhanced properties (Machado et al., 2007). It also was less expensive than vulcanite and aesthetically more pleasing. From then on, PMMA has been in use. Recently, additional polymers such as nylons, vinyl acrylic and light activated urethane dimethymethcarylate have been evaluated for use as denture base materials (Diaz-Arnold et al., 2008). Even if these materials do exhibit very capable properties, none of them have been deemed superior to PMMA. However, clinical studies (Ray et al., 2014; Dhiman & Chowdhury, 2009) have reported midline fractures to be a common problem in maxillary complete dentures due to fatigue
This prosthesis cannot be removed by the patient. It necessitates sacrificing of natural tooth structure, which unfortunately could lead to loss of vitality of the abutments. In a recent systematic review (Pjetursson et al. 2015), the survival rate of metal-ceramic fixed partial denture over five years is estimated to be about 94.4%, reinforced glass ceramic fixed partial dentures is 89.1% , glass-infiltrated alumina fixed partial dentures is 86.2% and the survival rate of densely sintered zirconia fixed partial dentures is 90.4% in 5 years of
The first procedure I observed was a placement of a porcelain-fused-to-metal (PFM) crown. The patient was in need of a crown due to fracturing tooth number 15. The procedure did not include anesthesia based on the patient’s preference. A
The pulp of teeth repeatedly undergoes irreversible disease caused by caries, trauma, congenital abnormalities, or as a complication of previous dental procedures (7). Endodontic therapy aims to an effective and specific treatment for the irreversibly diseased pulp, with preferable short- and long-term outcomes (7,8). However, endodontic prognosis studies have conclusively shown that the presence of pre-operative infection, generally determined by lack of response to vitality tests and the presence of a radiolucent periapical lesion, reduces the long-term outcomes of treatment by about 15-20%, compared with cases with vital pulp (8). While the prognosis of endodontic treatment in these cases remains favorable, the situation is more complicated incases with young immature teeth. Root canal instrumentation, disinfection, and sealing are more technically difficult to performing these cases (9-11). Perhaps more importantly, the tooth remains weak and is therefore susceptible to fracture due to functional stresses or minor trauma, an outcome that has been determined to range from 28-77%, depending on the degree of root maturation (13).This distinction is important, given that calcium hydroxide is rarely used long-term today, because of the availability of apexification techniques that rely on these of
The artificial teeth were arranged by using denture teeth (Trubyte Portrait IPN, TP; SR Vivodent DCL, SR) and Type II baseplate wax (TruWax Baseplate Wax; Dentsply International Inc, York, PA) (Fig 14). The trial maxillary IAORPD was tried-in and esthetic and phonetic were evaluated. The prosthesis was processed with heat-polymerized acrylic resin, Lucitone 199 (Dentsply International Inc., New York, PA). The occlusion was adjusted after deflasking procedures, and the prosthesis were finished and

Traumatic dental injuries are the most common of all the facial injuries and majorly involve maxillary incisors because of its position in the arch (4). Luxation injuries occur commonly in the primary dentition and mainly due to the resiliency of the alveolar bone (5). Treatment decisions for primary teeth are based on the degree of displacement, root formation and the ability of the child to cope with the emergency situation. Immediate repositioning and stabilization of laterally luxated teeth in their anatomic position are essential for the healing of periodontal ligament and to maintain esthetics and functional integrity (6, 7). Indications for extraction are severe injury or if the tooth is nearing exfoliation.
