The three main factors in complete denture construction are mechanics, esthetics, and phonetics. Out of which phonetics is generally given least importance as the tongue tends to adapt and patients tend to return to normal speech after a post insertion practice period of several weeks to several months. This may not be acceptable to certain group of people in accordance with their needs to speak socially or vocationally. An accurate approximation of palatal contours of a maxillary complete denture to patient’s tongue can improve intelligibility and decrease the post- insertion practice period. This article outlines a technique to replicate the patient’s palatal anatomy onto the polished palatal surface of a complete denture.

The topical literature lacks any comparison between stereolithography (SLA) and direct light processing (DLP) printing methods with regard to the accuracy of complete denture base fabrication, thereby utilizing materials certified for this purpose. In order to investigate this aspect, 15 denture bases were printed with SLA and DLP methods using three build angles: 0°, 45° and 90°. The dentures were digitalized using a laboratory scanner (D2000, 3Shape) and analyzed in analyzing software (Geomagic Control X, 3D systems). Differences between 3D datasets were measured using the root mean square (RMS) value for trueness and precision and mean and maximum deviations were obtained for each denture base. The data were statistically analyzed using two-way ANOVA and Tukey’s multiple comparison test. A heat map was generated to display the locations of the deviations within the intaglio surface. The overall tendency indicated that SLA denture bases had significantly higher trueness for most build angles compared to DLP (p < 0.001). The 90° build angle may provide the best trueness for both SLA and DLP. With regard to precision, statistically significant differences were found in the build angles only. Higher precision was revealed in the DLP angle of 0° in comparison to the 45° and 90° angles.

AbstractSeveral difficulties are encountered in providing a successful, single complete denture treatment. This case report deals with successful rehabilitation of completely resorbed mandibular ridge opposing a full complement of natural teeth prosthetically incorporating metal denture base in place of the conventional Poly Methyl Methacrylate material to combat the masticatory forces from natural dentition and improve the longevity of the prosthetic rehabilitation, at the same time improving the strength of the mandibular denture base.

AIM: The objective of the present study was to evaluate the effect of different denture base materials on the stress distribution in TMJ articular disc (AD) in complete denture wearers.MATERIAL AND METHODS: Two three dimensional Finite Element (FEA) models of an individual temporomandibular joint (TMJ) were built on the basis CT scan. The FEA model consisted of four parts: the condyle, the articular disc, the denture base, and the articular eminence skull. Acrylic resin and chrome-cobalt denture base materials were studied. Static loading of 300N was vertically applied to the central fossa of the mandibular second premolar. Stress and strain were calculated to characterize the stress/strain patterns in the disc.RESULTS: The maximum tensile stresses were observed in the anterior and posterior bands of (AD) on load application with the two denture base materials. The superior boundaries of the glenoid fossa showed lower stress than those on the inferior boundaries facing the condyle.CONCLUSIONS: Within the limitations of the present study it may be concluded that: The denture base material may a have an effect in stress-strain pattern in TMJ articular disc. The stiffer denture base material, the better the distribution of the load to the underling mandibular supporting structures & reducing stresses induced in the articular disc.

O presente trabalho teve como intuito apresentar um relato de caso que exigiu intervenção cirúrgico-protética para confecção de uma prótese total imediata em uma paciente com periodontite crônica. Paciente do gênero feminino, 40 anos, que se apresentou no plantão da Clínica de Periodontia da Universidade Federal de Alfenas - UNIFAL, manifestando como queixa principal “os dentes amolecidos”. Após anamnese e exame clínico, foi solicitado o exame radiográfico. Por meio deste, pode-se constatar a presença de periodontite crônica, dentes com extensa destruição coronária por cárie e presença de raízes residuais. Para tanto foi delineado o planejamento desta paciente com o objetivo de reabilitar a saúde bucal, estética e a função através da prótese total imediata. As próteses totais imediatas representam um procedimento clínico necessário, vantajoso e eficaz para pacientes que, inevitavelmente, deixarão de apresentar uma condição dentada ou dentada parcial.
