PURPOSE: The aim of this study was to compare denture wearer's evaluation and clinician's technical rating for complete denture used on edentulous patients. MATERIALS AND METHODS: Total 43 edentulous patients who had complete denture fabricated more than one year ago were recalled. The questionnaire based on the various literatures was modified and applied to patients for subjective assessments. Functional aspects related to retention, stability, occlusion and denture condition were included in operator's evaluation. In addition, correlations were evaluated between patient's subjective and operator's objective assessments. Friedman test and Cohen's Kappa value were used for statistical analysis. RESULTS: It was found that denture wearers' evaluations were slightly or fairly agree to clinician's rating for complete denture. More differences were found in maxillary denture than mandibular denture and moderate difference was found in esthetic, occlusion aspects. CONCLUSION: There were slightly or fairly agreement between subjective and objective evaluations.

It is difficult to make impression and fabricate conventional dentures for patients with microstomia and flat ridge. This is a case report of 53-year-old female with limited mouth opening (25 mm) who had been wearing denture for 7 years and which was recently broken. Close mouth with suction impression method was used. Proper diagnosis and appropriate set of procedures and methods were needed for this patient. The conventional complete denture fitted with closed mouth method for this condition resulted in retentive and stable denture which was inserted and removed easily.

CAD/CAM technology has already been used in most areas of prosthetics. The range of CAD/CAM application in denture fabricating process has been gradually increasing since the CAD/CAM technology was introduced for the fabrication of complete dentures in 1994. This paper describes a technique that combines conventional and CAD/CAM technology for the fabrication of complete dentures: the master casts from a conventional impression techniques were scanned first, and the wax denture was fabricated using Amann Girrbach's Ceramill full denture system (fds). The purpose of this paper is to introduce the case in which making an esthetically and functionally satisfied denture in shorter time is possible with CAD/CAM technology.

Flabby ridges commonly occur in edentulous patients. Inadequate retention and stability of a complete denture are the often encountered problems in these patients. A liquid supported denture due to its flexible tissue surface allows better distribution of stress and hence provides an alternate treatment modality in such cases. This case report presents the use of a liquid supported denture in a patient with completely edentulous maxillary arch with flabby tissue in anterior region opposing a partially edentulous mandibular arch.

PURPOSE: The aim of this study was to evaluate correlations between denture satisfaction and various factors related to patients' and wearing dentures. MATERIALS AND METHODS: Total 43 edentulous patients were recalled and they were wearing complete dentures fabricated more than one year ago. For patients' subjective assessment, the questionnaire based on the various literatures was developed and applied to patients for data acquisition. In addition, correlations were evaluated between subjective assessment and denture satisfaction score. For statistical analysis, Spearman correlation coefficient, multiple regression analysis, Mann-whitney U test and Kruskal-Wallis test were used to found out what the most considerable factors to denture satisfaction score (P < 0.05). RESULTS: Denture satisfaction score of maxilla was higher than mandible (P < 0.05). In functional aspects, maxillary denture were received a favorable evaluation. Especially fit and pain causing were highly correlated to satisfaction. Gender, age, using period, visiting times after manufacturing denture were unrelated to satisfaction. But previous experience was related to denture satisfaction. CONCLUSION: Denture satisfaction was determined by a combination of various factors related to patients.

This study helps to clarify conflicting reports by comparing the physical properties and accuracy of complete denture processed by the pack and press technique, continuous-pressure injection technique(SR-Ivocap system) and Mark press technique. The 6 different specimens have been evaluated using the SEM, Impact test, DSC (Differential Scanning Calorimetry) and DMTA(Dynamic Mechanical Thermal Analysis). Each sample was made of SR-Ivocap resin and QC-20 resin by different processing methods. The results were as follows ; 1. As the result of the observation on the fracture surface of resin by use of SEM, sample SR-Ivocap resin cured by continuous pressure injection method showed the most homogeneous structure. This is why molecules in SR-Ivocap resin have no orientation. 2. As the result of the Impact test in order to measure the deformity, fracture energy and impact resistance of resin, the samples with QC-20 acrylic resin and SR-Ivocap resin cured by continuous pressure injection method were exellent. 3. In consequence of measuring alpha-glass transition temperature by use of DSC on the basis of temperature change, the glass transition temperatures of sample QC-20 resin cured by pack and press method and sample SR-Ivocap resin cured by continuous pressure injection method were very similar. Thus volumetric stability could not be evaluated only by glass transition temperature. 4. In comparing volumetric stability data by DMTA, the glass transition temperature(Tg) showed 137.88degrees C at sample QC-20 resin cured by pack and press method and 139.78degrees C at sample SR-Ivocap resin cured by continuous pressure injection method. Therefore sample SR-Ivocap resin cured by continuous pressure injection method seems to be superior to sample QC-20 resin cured by pack and press method in the dimensional stability at high temperature. 5. In comparing storage modulus data by DMTA, the storage modulus of sample SR-Ivocap resin cured by continuous pressure injection method was higher than that of sample QC-20 resin cured by pack and press method. So, sample SR-Ivocap resin cured by continuous pressure injection method seems to be superior to sample QC-20 resin cured by pack and press method in impact strength.
