PURPOSE. To compare the changes in the occlusal vertical dimension, activity of masseter muscles and biting force after insertion of immediate denture constructed with conventional, tooth-supported and Implant-supported immediate mandibular complete denture. MATERIALS AND METHODS. Patients were selected and treatment was carried out with all the three different concepts i.e, immediate denture constructed with conventional (Group A), tooth-supported (Group B) and Implant-supported (Group C) immediate mandibular complete dentures. Parameters of evaluation and comparison were occlusal vertical dimension measured by radiograph (at three different time intervals), Masseter muscle electromyographic (EMG) measurement by EMG analysis (at three different positions of jaws) and bite force measured by force transducer (at two different time intervals). The obtained data were statistically analyzed by using ANOVA-F test at 5% level of significance. If the F test was significant, Least Significant Difference test was performed to test further significant differences between variables. RESULTS. Comparison between mean differences in occlusal vertical dimension for tested groups showed that it was only statistically significant at 1 year after immediate dentures insertion. Comparison between mean differences in wavelet packet coefficients of the electromyographic signals of masseter muscles for tested groups was not significant at rest position, but significant at initial contact position and maximum voluntary clench position. Comparison between mean differences in maximum biting force for tested groups was not statistically significant at 5% level of significance. CONCLUSION. Immediate complete overdentures whether tooth or implant supported prosthesis is recommended than totally mucosal supported prosthesis.

In fully edentulous cases, which are accompanied by severe residual ridge resorption and impairment of supporting tissues of complete dentures, proper diagnosis and systemic treatment planning are required for the improvement in retention, stability, and support of prosthesis. Provisional restoration, while it is unfamiliar in complete denture restoration, can be used as a valuable tool, which makes possible to evaluate the stability of complete dentures and receive feedback from patients in complex clinical situations. In this case, a provisional denture was used to improve stability of impression, polished, and occlusal surfaces of complete denture, and to consider esthetic requirements before final denture construction. The result was clinically satisfactory in terms of functional and esthetical aspects.

PURPOSE. The purpose of this clinical study was to evaluate the frequency and type of prosthetic complications in relation to type and properties of removable dentures and to investigate the influence of these complications and several data about the existing dentures on patient satisfaction. MATERIALS AND METHODS. Ninety nine patients (44 males and 55 females) wearing removable dentures have been included in the study. The complications of the patients were recorded; patient satisfaction was determined with a Visual Analog Scale (VAS) and the relationship of complications and patient satisfaction with several data about the dentures such as denture age, type of denture, centric relation and vertical dimension was investigated. Kruskal Wallis, Mann Whitney U and Chi square tests were used for statistical analyses. The results were evaluated statistically at a significance level of $P$ <.05. RESULTS. Need for addition of artificial teeth for dentures with correct centric relations was found to be significantly lower than dentures with wrong centric relations ($P$ <.01). Loss of retention, ulcerations and high vertical dimension affected the VAS chewing ability scores negatively and ulcerations affected the VAS phonation scores negatively ($P$ <.05). CONCLUSION. Considering the results of this study, it can be concluded that loss of retention, ulcerations and high vertical dimension caused patient dissatisfaction. Additionally, dentures with wrong centric relations caused need for addition of artificial teeth.

Severely absorbed edentulous ridge cannot bear mechanical stress, causes undesired transformation of oral environment and makes patients difficult to adapt to dentures. Nowadays implant overdenture can be a treatment of choice in order to relieve patients' discomfort and improve stability and retention of the denture. Placement of implant on maxilla is difficult because of its bone quality and anatomic structure. It also has wide supportive tissue and convenience of border sealing, which provides sufficient support and stabilization with conventional complete denture. Mandible, on the other hand, is difficult to obtain sufficient support, retention and stabilization with conventional complete denture. Therefore, implant overdenture is recommended on mandible. Locator attachment has been improved for convenience of use and male parts of various retention enabled it to replace ball type attachment clinically. In this study, we restored maxillary arch with conventional denture, and mandibular arch with implant and tissue-supported overdenture and Locator attachment system.

There are various approaches to treatment for patients with fully edentulous jaw. In maxilla, it is easy to obtain sufficient stability, support, and retention with the traditional full denture method. In mandible, however, there are difficulties caused by anatomical limitations. In this case, treatment with implants can be considered. If it is difficult to place implants in posterior area, a fixed complete denture can be considered, using 4 - 5 implants anterior to mental foramen. This approach has changed in many ways, such as surgical methods and materials used, over the years. This case report compares two approaches and their changes over time, especially in the cases of mandibular fixed prostheses using implants, paired with maxillary complete denture.

For this study, self curing resin and heat curing resin used for existing usual resin denture base in the denture industry were chosen by manufacturer. Curing tests for 30-minute, I-hour, 2-hour and 3-hour were conducted to know the strength of the resins and conduct analysis to get other necessary information. The results obtained are as follows: 1. Heat curing resins show a little differences among the manufacturers. However 30-minute curing resin shows great difference as shown in the fracture strength test. 2. The effect from the granularity of the resins on the fracture strength was found insignificant which means there is no difference between coherence and strength. 3. To summarize the results from each time level, the longer the time is, the more the minute cracks on the surface, which is the cause of reduced strength. From this test, it was identified that in making the denture base for patients in dental clinics, 30-minute curing is most efficient and effective in reducing discoloration and monomers, although long-time curing has been considered to be the principal.

When wearing complete dentures, patients want to function naturally within a physiologically stable range. To do this, recovery of esthetics, biologically stable arrangement and contour, and occlusal contacts with denture stability are necessary. In this case report, a complete denture patient of adverse conditions was presented. To increase stability of the dentures, functional impression was made by border molding using the neutral zone. The dentures were checked for physiological centric relations and stable occlusion. The clinical results showed satisfactory results on function and esthetics.

Dental care is becoming more available on the NHI(National Health Insurance) in Korea. Especially, complete denture, partial denture, dental scaling, and dental implant has been applied by NHI from 2012 to 2014. Although, the entire nation is not eligible for the benefit now, the more dental coverage of NHI is extended, the more regulaition is tightened. Essential documents for proof of correctness of dental treatment covered by NHI are dental records and the receipt book. Summary of regal regulation about them is as follows 1. Chief complaints of patients, diagnosis, progress, and act of treatment, drugs and materials of treatment, doctor's sign, date and hour should be placed accurately on dental record 2. Dental clinic should collect patients sharing of the dental cost covered by NHI. 3. Dental clinic should keep the receipt as proof of purchase of dental drugs or materials.

Patients who get tooth loss would also lost their esthetic, stability and functional aspect suddenly. They have to get provisional restoration immediately. This case reports a satisfied result that thermoforming technique is good for patients to get injury from unexpected tooth loss.
