[The development of the deciduous dentition under the influence of differently shaped pacifiers].

Intending to perform a prospective study after the birth of their children 312 mothers were asked for co-operation and a newly developed preventively shaped pacifier was given them (free of charge) for use. Two years later it was possible to join 202 children and morphologically investigate their primary dentition. On the base of the real behaviour in the meantime the subjects formed five groups: children without sucking habits, finger suckers, user of cherry-shaped pacifiers, so-called health pacifiers and test pacifiers. The findings show specific significant differences. Especially cherry-shaped pacifiers but also medically recommended pacifiers can badly influence the development of the deciduous dentition. However, the harmful results can be minimized by a special preventive shape.

[The development of methods for the objective assessment of occlusal parameters].

For reasons of different data in literature on occlusal parameters and their metric registration, at the beginning of the 80's two methods independent of each other were developed--the capacity measuring method and the quasiplanimetry method to register the total occlusal contact area and the number of occlusal surfaces of contact at dental casts. The results obtained independently from each other showed a high degree of correspondence. That's why the method of quasiplanimetry was further developed and used for the direct analysis of enorally obtained wafers of different characteristic. The method is improved now with a modern system of digital analysis. The results obtained up to now admit the conclusion that the occlusion of the teeth represents an individual condition of high variability. With the reproducible method used individual occlusal parameters can be numerically registered.

Findings of dentitions whose orthodontic treatment by removable appliances with and without extractions was ended about 23 years ago.

Out of a total of 300 patients the data of which and the dental casts including a control cast after an interval of 3 years were completely available, 56 patients could be investigated after an interval of about 20 years. When obtaining the last impressions they were aged 38 1/2 years. All casts were estimated and evaluated according to the method of Eismann (1969). It gives prerequisites to different dentofacial anomalies to compare them with each other under reproducible conditions. 15 factors are used in the assessment of the morphology of the dentition. Each of the criteria is measured and the results are evaluated according to the table. Points are scored for each condition registered and the total number will signify the extent of the morphological abnormality. The reduction of the numerical value between the initial and final casts is a measure of the success of treatment, and the difference between the score for end-of-treatment and follow-up casts is a measure of the degree of stability. Thus the cases between the end of treatment and the first control casts showed a slight improvement of the results. Between the first and the last control casts two trends were observed. On one hand single dentitions showed a further improvement, on the other the amount of the dentofacial anomaly symptoms increased a little. There are no trends derivable that there are special reacting differences between the extraction therapy group compared to the patients without extractions. The individual mode of reactions seems to be the most important factor with respect to the morphological changes independent of type of treatment.

The total surface and number of occlusal contacts in the static and dynamic occlusion of the teeth. Development of the methods.

For reasons of different data in literature on occlusal parameters and their metric registration at the beginning of the eighties two methods, independent from each other, were developed to registrate the total occlusal contact area and the number of occlusal surfaces of contact on dental casts--the capacity measuring method and the quasi-planimetry method. The results obtained independently from each other show a high degree of correspondence. Because of its easy handling the method of quasi-planimetry was further developed and used for direct analysis of enorally obtained wafers of different characteristics. The total surface of occlusal contacts in the static occlusion ran up to 4-6 mm2, and the number of stops to 19-30. The method of qualitative and quantitative analysis of occlusal parameters is improved with a modern system of digital analysis. The results obtained up to now admit the conclusion that the occlusion of the teeth represents an individual condition of high variability.

[Individual overbite behavior between the deciduous and permanent dentition].

Manuals and relevant publications give rise to the impression that the formation of the overbite in the incisor region throughout its development is a process easy to overlook. Impressions of 108 cases were taken, one of the deciduous dentition and one of the permanent dentition 13 years later. A mathematic-statistical analysis of objective measurable morphological dentition criteria were made and discussed. This shows that neither from the degree of overbite nor from any other feature of the deciduous dentition a prognosis concerning the extent of the final overbite of the permanent dentition can be derived. Changes throughout the development of the overbite are predominant. There are only little correlative coherencies among the morphological symptoms that can be applied quickly and easily for the prognosis in the clinical inspection. For estimating the development tendency longterm individualized observations are necessary.

Periodontal findings before and after orthodontic therapy in cases of incisor cross-bite.

Maloccluding incisors are subject to over-loading in chewing which adversely affects the health of the periodontal tissues. Following orthodontic treatment the effect of the masticatory forces is normalized. This results in the recovery of these tissues as demonstrated by evaluation of clinical findings before and one year after treatment. The results emphasize the necessity for and effectiveness of orthodontic treatment.

[Combined valuation of the success of therapy of orthodontic anomalies, periodontal diseases and dental caries].

Using the DMF/T, GPM/T and CPITN-index systems, the numerical evaluation method according to Eismann and measuring the occlusal contact areas in static occlusion in 101 orthodontically treated adolescents and young adults the effect of complex preventive and therapeutic programs was studied. The used parameters allow to characterize oral health status. After completing the orthodontical treatment there is a need to continue preventive programmes and therapeutic interventions in adults to reach stable oral health conditions.

[Objectivization of the methods for recording the total contact surface and the number of occlusal contacts in static occlusion].

The occlusal contacts of teeth in a dentition have been analysed metrically with the aid of a new method. The outstanding advantage of this method is offered by the fact that the contacts of teeth are registered immediately in the subject and then evaluated with the aid of the teleplanimetric measuring variant. From error computation it follows that the method leads to reproducible and largely objective results. In 84 subjects with an average age of 16.9 +/- 3.7 years the total contacting area and the number of contacts in static occlusion were determined and examined with respect to specific groups.
