[Comparison of location between nasion and orbital points on soft tissue and on bony structures, in articulatory technique].

A skin projection of the orbitale as palpated through soft tissues was designated on the left cheek of 22 subjects. The nasion, orbitale and cephalostat nasion direction medium were plotted on transparent paper after teleroentgenography. Mutually parallel lines were drawn through the points, the line obtained on the construction of the nasion direction medium used as a basic one. Distances between the lines were measured and results statistically processed. Transfer of the model into the articulatory region by means of the orbitale and buccal arch nasion direction appeared not to orientate reliably the model according to reference planes of the head. Our results are consistent with literature data available.

[Evaluation of the reconstruction of occlusal plane by use of Ponans angle].

In this study, teleroentgenocephalograms of 34 subjects with at least 20 natural teeth were used. Correlation between the angle formed by linking the PORION-NASION-SPINA NASALIS ANTERIOR (PONANS angle) points and the angle made by Frankfort horizontal and occlusion plane was studied. The coefficient of correlation was 0.1263. It is considered that there is no correlation if the coefficient of correlation is less than 0.5. Thus, there was no correlation in the study sample, which is consistent with the results reported by Karkazis and Polyzois, but in disagreement with those published by Monteith. In our sample, the occlusion plane could not be oriented in the articulatory space or in toothless mouth by means of the method proposed by Monteith.

[Radiographic analysis of condyle position in patients with TMJ dysfunctions].

Decreased joint space is one of the basical radiographic signs of joint disease and correlation with crepitus the real clinical symptom of structural joint damage. The aim of this investigation is to find out if there is any correlation between the intrajoint condyle position and joint dysfunction symptomatology, by means of TMJ tomography evaluation. Among the patients with characteristic symptoms of TMJ dysfunction examined in our Departments, a group of hundred were tomographed (Polytom--Philips-Massiot). Thirty students not showing any anamnestic or clinical symptoms formed the control group. In the evaluation of radiographic findings we accepted the static relation between condyle and glenoid fossa in the maximal intercuspal position, where the joint space was divided in three almost equal parts. The radiographic findings of the relationship between condyle and glenoid fossa in the maximal intercuspal position are presented on with the intention of establishing the most characteristic differences between the groups. The statistical elaboration has been carried out by multivariante analysis of variance. The characteristic radiographic findings in our group of patient are: --excentric condyle position, --posterior condyle displacement and --marked asymmetry. Therefore, these findings represent efficient aid in TMJ dysfunction diagnosis, and show direction for repositioning of condyle in therapy dysfunction.

[Glass-ionomer cements].

Glass-ionomer cements represent a new type of dental materials widely clinically applied owing to their good adhesion to dental tissue, caries-protective effects, biocompatibility and simple handling. They are two-component materials commercially available in forms of powder or liquid. The two components are mixed manually or automatically in a vibrator to produce a compact mixture. In addition to chemical, light-polymerizing hybrid glass-ionomer cements are also available. A description is given of physical and chemical features of these materials, their classification and use in particular clinical cases.

[Positions of the central relation and central occlusion as recorded by a functiograph in patients with a stomatognathic system dysfunction].

Positions of the central relation and central occlusion were intraorally graphically recorded in 100 patients with a stomatognathic system dysfunction and in 0 control subjects. Results of the study showed asymmetry of these two positions to play a major role in the etiology of dysfunction. Occlusal program had an almost two-fold impact on the graphic tracing of the central occlusion position, as compared to the influence exerted by the articulation and muscle on the central relation tracing. Instrumental functional analysis and the instrument used alike, are simple to use and allow an objective assessment of the state to be made.

[Design of bond cast bridges].

A technique of etching was employed in 50 patients for bridge retention. The Rexillium III (Jenevie Industries, Wallingford Co.) alloy and Comspan bond (L. D. Caulk Co., Milford Del.) were used. Therapeutic results obtained with adhesive (etched) bridges depend on a variety of factor: careful and accurate indication, precise work plan, minimal preparation of the supporting tooth, appropriate method of retention of the attachment metal portion, and the type of bond and of dental alloy. Clinical application of bond cast bridges has a quite good prognosis. A prolonged period of observation should provide more data on the behavior of such appliances in the oral cavity and allow us evaluations.
