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?.

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.

Background: The purpose of this paper is to describe an anatomical variation of the hand extensor on the little finger of the right hand which receives four tendons, condition unknown, as it is the first case reported so far in the literature. The human extensor tendons of hand often display an array of variations. Awareness of the anatomy and variations of the extensor tendons on the dorsum of the hand is necessary not only for the anatomist but also for surgeons when considering tendons for hand surgery, tendon rerouting or transplants. Materials and Methods: Bilateral anatomical variation in the upper limb was found during routine dissection in a 75-year-old male cadaver in the Morphology Laboratory at the University of Pamplona. The variations were recorded and photographed. Result: In the left hand the extensor digitorum there was a single tendon to the index, double tendon to the middle, triple tendon to the ring finger, a single tendon to the little finger or digiti minimi. The extensor digiti minimi has double tendon. In the right hand the extensor digitorum there was a single tendon to the index, triple tendon to the middle finger, triple tendons to the ring finger, a double tendon to the little finger. The extensor digiti minimi has double tendon. The little finger receives four tendons, 2 of extensor digitorum and 2 of extensor digiti minimi. The dorsum of the left hand and right showed juncturae tendinum type 2, between the extensors tendons in the 3rd intermetacarpal space; type 3, between the extensors tendons in the 4th inter metacarpal space. Conclusion: The presence of multiple tendons may alter the kinematics around the site of attachment to the phalanx. Knowledge of anatomical variations and normal anatomy of the extensor tendons, may be helpful while performing graft and tendon transfer operations.Bangladesh Journal of Medical Science Vol.15(2) 2016 p.278-282

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.

This article deals with the determination of the rate of convergence to the unit of each of three newly introduced here multivariate perturbed normalized neural network operators of one hidden layer. These are given through the multivariate modulus of continuity of the involved multivariate function or its high-order partial derivatives and that appears in the right-hand side of the associated multivariate Jackson type inequalities. The multivariate activation function is very general, especially it can derive from any multivariate sigmoid or multivariate bell-shaped function. The right-hand sides of our convergence inequalities do not depend on the activation function. The sample functionals are of multivariate Stancu, Kantorovich and quadrature types. We give applications for the first partial derivatives of the involved function.
