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?.

Pain Symptoms

This article presents the analysis of the relevant literature highlighting the mechanisms of the development of malocclusion and pain symptom at the reduced occlusal vertical dimension. In this case, the key complaint presented by patients is permanent steady pain described as dull, stabbing, or compressing by its character. Most often, the pain is localized within the paratoid-masticatory area as well as buccal, temporal and frontal areas, and irradiates to the upper and lower jaw or the teeth that often leads to performing unnecessary dental manipulations; to the region of the temporomandibular joint (TMJ); to the ear that sometimes is accompanied with fullness and tingling in the ears. In some cases this pain can irradiate to the hard palate and tongue. Many patients note the growing intensity of pain when chewing. Some patients experience episodic increase in pain when there are pain attacks described as compressing or stabing in the background of steady dull pain. The pain gets more intense even at the slightest movements of the head, lower jaw, or when speaking. The duration of the pain attack is approximately 20–30 minutes. A few minutes before the onset of the attack, all patients notice the emergence of somes forerunning symptoms, e.g. hyperlsalivation, paresthesia, toothache. The attacks can be provoked by conversation, overcooling, and emotional tension. It has been experimentally proven that a prolonged muscle contraction, which is often observed during emotional stress, can cause pain in the regions mentioned above. But whether will it arise or not and to what extent, it depends on the state of adaptive capacity of the body and dentofacial system. When the adaptive capacity of the body and the dentofacial system as its part are weakened, the local background for the occurrence of pain symptoms in the maxillofacial area may be: affective states (depression, anxiety), prolonged chewing load, and prolonged neck muscle tension during dental manipulations. Among the local factors that can cause pain, malocclusions rank the leading place. For example, a hyperbalancing contact is a sign of impaired muscle activity and coordination during the maximal closure of teeth in the lateral position of the mandible, and occlusal contacts on the balancing side affect the distribution of muscle activity during parafunctional closure, and this redistribution can impact on the temporomandibular joint (Andres K. H. et al.). Occlusion abnormalities may result from reduced occlusal vertical dimension, deformation of the dentitions caused by periodontal disease, partial loss of teeth, pathological tooth wearing, as well as due to improperly inserted fillings, unfit inlays, onlays, crowns. Reduced occlusal vertical dimension can also cause otalgia and some other otorhinolaryngological problems, pathogenesis of which is quite debatable and controversial in current literature. J. S. Costen considered hearing loss, tingling and other ear symptoms are associated with pressure produced by the head of the mandible joint onto the auditory tube. Reducing the vertical occlusal dimension results in increasing pressure of the head of the mandible joint onto the subtle bone arch of the articular fossa, which separates the cavity of the joint from the dura mater; this can trigger dull pain in the spine. It is important to remember that pain is a symptom that most often makes patients to search for a dental care. Pain is one of the first clinical manifestations of the body decompensation. Patients with TMJ dysfunction who experience the pain symptom is to a greater or lesser extent make up a group of patients who require a special integrated approach in their treatment.

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.
