Goal of the study : To detect the prevalence, association and correlation that may exist between the vertical dimension of occlusion and certain facial clues in a toothed population in search of a simplified method for the determination of DVO in complete edentulous people.Introduction : The methods for recording the vertical dimension of occlusion, rest or phonetic vertical are very numerous, attesting to the absence of a universal scientific method for its determination. The aesthetic criterion of respecting morphological proportions constitutes for many authors a preferential reference guide. Determining the vertical occlusion dimension (DVO) remains a complex and imprecise step using several complementary methods. Exploitation of clues Facials seem a simple and promising means but a subject still to controversies. Material and method : We conducted a diagnostic study, spread over a period of one and a half years within the faculty of dentistry of Rabat. The facial indices studied were as follows: the inter-pupillary distance, the distance between the inner canthus and the labial commissure, the distance between the center of the pupil and the labial commissure, the internal canthus distance from the eyes × 2, the external canthus distance from the ear, the distance between external canthus and internal canthus (opposite eye), width of eyes × 2 and distance between external wing of nose and eyebrow. The measurements (DVO and different facial clues) were taken by the same operator directly on the toothed subjects, using a caliper.Results and discussion : On the 103 subjects, our sample presented a predominantly female with an average age of 21 years ± 3.9. The average vertical occlusion dimension was 50.49 mm ± 6.45. We noted a concordance between the DVO and two facial indices namely the internal canthus-labial commissure distance (51.16 mm ± 6.11) and the center of the pupil-labial commissure distance (52.18 mm ± 6.66). The reliability analysis was in favor of a positive, strong and very significant correlation between the DVO and the following measures: the inter-pupillary distance, the internal canthus distance-labial commissure and the center distance of the pupil-labial commissure (p <0.001). By adjusting the inter-pupillary distance, the internal canthus-labial commissure distance, the center distance of the pupil-labial commissure, the internal canthus distance from the eyes × 2, the external canthus-ear distance, the width of the eyes × 2, the distance between the external wing of the nose and the eyebrow, only the distance between the internal canthus and the labial commissure, the distance between the external canthus and the ear and the width of the eyes × 2 were explanatory variables for the DVO.Conclusion : The inter-pupillary distance, the internal canthus-labial commissance distance and the center distance of the pupil-labial commissure approximate the vertical dimension of occlusion in the dentate subject. The use of these facial indices seems interesting in complete removable prosthesis because of its simplicity and speed.

The aim of this study is to demonstrate the use and the effectiveness of cephalometry and golden proportions analysis of the face in planning prosthetic treatments in totally edentulous patients. In order to apply this method, latero-lateral and posterior-anterior X-rays must be performed in addition to the common procedure. Two main concerns for totally edentulous patients are the establishment of the vertical dimension and the new position of the occlusal plane. The divine proportion analysis was carried out by the use of a golden divider. The prosthetic protocol was divided into three steps and a case was selected for better understanding. Referring to the golden relations, if the distance from the chin to the wing of the nose is 1.0, the distance from the nose to eye is 0.618. This proportion is useful and effective in determining the correct prosthetic vertical dimension. The incisal margin of the lower incisor must be positioned between Point A (A) and protuberance menti (Pm) according to the gold ratio 0.618 of the total height A-Pm. Posteriorly the occlusal plane must be placed 2 mm below the divine occlusal plane (traced from the incisal margin of lower incisors to Xi point). A prosthesis made in accordance with cephalometric parameters and divine proportions of the face helps to improve the patient’s aesthetics, function and social personality.

The intermaxillary relations refer to the position of the mandible in relation to the maxilla in the vertical and horizontal planes, being the occlusion vertical dimension (OVD) and the centric relation (CR) essential in the treatment with complete dentures. This article reports a case of reestablishing intermaxillary relations with conventional complete dentures (CCD).A 82-year-old male patient sought care to replace his complete dentures due to dissatisfaction with the aesthetics and chewing function. After anamnesis and extra and intraoral exams, it was found that the current complete dentures showed large wear of the teeth, causing decreased OVD, aesthetic, and masticatory damage. The edges had satisfactory conditions for CCD rehabilitation. From the anatomical impressions of edges were obtained study models for making individual trays, later used for functional impression and obtaining the working models, on which were made wax plans. After adjustment of the upper wax plane and registration of the facial arch, the upper model was mounted on the semi-adjustable articulator. For the determination of the OVD, metric, physiological, aesthetic, and phonetic methods were used, and for the determination of CR, manipulation and physiological methods were used. The inferior model was assembled after determination of intermaxillary relations. Teeth were selected and mounted. In the aesthetic and functional testing of the teeth, occlusion, OVD, and esthetics were restored. The dentures were polymerized and installed. In proservations, the patient reported improvement in chewing, aesthetics, and phonetic. It was concluded that the reestablishment of intermaxillary relations contributed to aesthetic, masticatory, and phonetic rehabilitation.

The Relationship

Background/Aim. The vertical dimension of occlusion is a very important parameter for proper reconstruction of the relationship between the jaws. The literature describes many methods for its finding, from the simple, easily applicable clinically, to quite complicated, with the use of one or more devices for determination. The aim of this study was to examine the possibility of determining the vertical dimension of occlusion using the vocals ?O? and ?E? with the control of values o btained by applying cognitive functions. Methods. This investigation was performed with the two groups of patients. The first group consisted of 50 females and 50 males, aged 18 to 30 years. In this group the distance between the reference points (on top of the nose and chin) was measured in the position of the mandible in the vertical dimension of occlusion, the vertical dimension at rest and the pronunciation of the words ?OLO? and ?ELE?. Checking the correctness of the particular value for the word ?OLO? was also performed by the phonetic method with the application of cognitive exercises when the patients counted from 89 to 80. The obtained difference in the average values i n determining the vertical dimension of occlusion and the ?OLO? and ?ELE? in the first group was used as the reference for determining the vertical dimension of occlusion in the second group of patients. The second group comprised of 31 edentulous persons (14 females and 17 males), aged from 54 to 85 years who had been made a complete denture. Results. The average value obtained for the vertical dimension of rest for the entire sample was 2.16 mm, for the word ?OLO? for the entire sample was 5.51 mm and for the word ?ELE? for the entire sample was 7.47 mm. There was no statistically significant difference between the genders for the value of the vertical dimension at rest, ?ELE? and ?OLO?. There was a statistically significant difference between the values f or the vertical dimension at rest, ?OLO? and ?ELE? for both genders. There was a statistically significant correlation between the value for the vertical dimension at rest, ?OLO? and ?ELE?, for both groups of subjects. Conclusion. Determining the vertical dimension of occlusion requires 5.5 mm subtraction from the position of the mandible in pronunciation of the word ?OLO? or 7.5 mm in pronunciation of the word ?ELE?.

Esthetics plays a crucial role in rehabilitation of removable dentures to achieve a pleasant smile. Denture esthetics is the effect produced, which improves the beauty and attractiveness of a person. With the advances of implants and ceramics, the conventional removable denture needs to be updated. denture characterization is a must in avoiding denture look and giving natural look. Giving the prosthesis as close as possible to the natural apparatus before the tooth loss is the key to a successful prosthetic, esthetic and functional rehabilitation. As a prosthodontist dealing in fulfilling the aesthetic challenges an economical alternative to high-end costly procedures is a must considering the Indian scenario, keeping in mind the biocompatibility and longevity of the treatment. As per literature light cure, gum staining is one of the techniques for masking denture base color and imparting natural color to mucosa but considering the cost involved many patients requiring aesthetic enhancement of prosthesis avoid going for such treatment thereby compromising their aesthetic. the present case series describe an innovative cost-effective alternative to the previously describe technique for masking the denture base color by using composite mixed with stains to replicate the natural apparatus.

This article reveals the philosophical grounds of the aesthetics of color, analyzes the correlation between the structures of philosophical and artistic comprehension of coloristics. Interaction of philosophy and art as the forms of cultural identity manifests in the sphere of intellectual understanding of the perception of color and its semantics in painting. In the hidden logic of contemplation of color, can be traced the outlines of the problematic of transcendental and intelligible in art conditions for the aesthetic approach towards chromatic space. Color creates the visual beauty, thus it is apparent why the aesthetic knowledge seeks to clarify to which extent we can assess the experience of color &ndash; the result of coloration of light. The art itself creates the so-called color ontology of the world. First the first time, the beauty of color and its perception are analyzed in the context of correlation between art and transcendental traditions of philosophizing &nbsp;(Descartes, Kant, early Husserl &ndash;&nbsp; his work &ldquo;The Philosophy of Arithmetic&rdquo;) that allows matching the key to a new interpretation of the tradition of color. Determination of its meaning requires comparing history and structure of the philosophical and artistic metaphor of color. It is demonstrated that the phenomenon of color is of crucial significance for the aesthetics, as it implies not only comprehension of the problem of correlation between nature and art, but also cognition of the beauty of color, its universal value for all forms of art, profound structures of perception of coloristic phenomena, picturesque unveiling of the color harmony of the painting.

Objective methods of determining the vertical dimension of occlusion (VDO) offer significant advantages because no radiographs or others special measuring devices are required. One of the objective measurement of vertical dimension of occusion is twice the intercanthal distance (ICD). The purpose of this study was to compare whether there was a difference between the length of VDO and the length of twice the ICD among Mongoloid race, which was represented by eighty students, chosen randomly from undergraduate students of Faculty of Dentistry Universitas Padjadjaran that fulfilled all criteria stated. Result showed that there was no difference between the length of VDO and twice the ICD in this population. Thus, in this study, the ICD can be suggested as a method to determine the VDO in this population.

Introduction. Optimal reconstruction of vertical dimension of occlusion is crucial for functional and physiognomic rehabilitation of edentulous patients. This article is aimed at presenting attitudes and studies on application of cephalometric analysis in obtaining optimal vertical dimension of occlusion. The review of literature presents the studies which analyse the possibilities of cephalometric analysis aimed at improving the clinical methods for vertical dimension of occlusion determination in treatment of edentulous patients. The research carried out so far can roughly be divided into: cephalometric vertical dimension of occlusion evaluation in dentulous patients performed to determine precise indicators of vertical dimension of occlusion and to establish cephalometric standards for practical application in prosthodontics; the method of producing pre-extraction cephalometric registries involves the production of cephalometric radiographs for potential prosthodontic patients in dental pre-extraction period which are kept for reference to be used in later therapy; the cephalometric method of registering the position of physiologic rest position of the mandible involves measuring cephalometric parameters in cephalometric radiographs made when the mandible is in physiologic rest position; cephalometric evaluation of vertical dimension of occlusion in complete denture therapy after clinical determination of intemaxillary relationship is recommended for timely detection of possible mistakes, with a possibility of correction in the process of complete denture production; and cephalometric analysis in edentulous patients with old complete dentures for a planned vertical dimension of occlusion extension. Conclusion. Data from the literature give no proof of a scientific and universally accepted method for precise determination of vertical dimension of occlusion, which is a point many authors agree upon. Different methods proposed for vertical dimension of occlusion determination in everyday practice are usually recommended in combination with other methods. Determination of individual, morphological vertical dimension of occlusion indicators by cephalometric analysis is, in this sense, one of the directions for finding a better solution when planning an artificial occlusion complex.

AbstractIn this paper, I discuss Kant’s concept-less schematism (KU, 5: 287) in the third Critique1 and make three claims: 1) concept-less schematism is entirely consistent with the schematism in the first Critique; 2) concept-less schematism is schematism with no empirical concept as an outcome; and 3) in accordance with 1) and 2), the imagination is free to synthesize the given manifold and leads to judgements of taste without this meaning either that the categories play no role at all or that these judgements are full-fledged cognitive determining judgements. While most commentators read the freedom of the imagination as its independence from the understanding, I argue that the freedom of the imagination is based on a non-determining employment of the pure concepts of the understanding. The freedom of the aesthetic imagination consists in the temporal schematization of the categories without any complementary determination of the empirical concept.

Kinematic data from neutral hydrogen observations provide information to solve the interdependent problems of the determination of the main Galactic constants (the Solar-Galactic center distance R0, the Oort constant A and others) and the Galactic rotation curve (Nikiforov & Petrovskaya 1994, hereafter NP94, and references therein). However, in the standard method for finding R0 by comparing the rotations of HI clouds and some other objects (typically HII regions/CO clouds), the kinematic model, constructed typically solely from HI data, is considered to be the same for both galactic subsystems (e.g. Merrifield 1992). In practice a discrepancy between their rotation curves can produce strongly erroneous results (Merrifield 1992, NP94). Establishing the common rotation law from HI plus HII/CO data in NP94 is only a part of attacking the problem.
