[The treatment of adults with removable appliances? A contribution to orthodontic-prosthetic collaboration]. / Erwachsenenbehandlung mit abnehmbaren Apparaturen? Ein Beitrag zur kieferorthopädisch-prothetischen Zusammenarbeit.

Request of adults for orthodontic treatment increases. In that cases requirements to the practitioner are of many kinds, especially if in consequence of secondary changes after lost of teeth the patient is not able, as in the past to accept his irregularities of teeth in relation to masticatory, physiognomic and phonetic function. Absolutely there is willingness to wear also removable orthodontic appliances. Possibilities and advantages of plates for orthodontic-prosthetic problems are discussed and examples of treatment demonstrated.

[Experimental studies on various model material. 3. Dimensional behavior and reproductive fidelity as compared to those of elastomers]. / Experimentelle Untersuchungen an verschiedenen Modellmaterialien. 3. Mitteilung: Das Volumenverhalten und die Wiedergabegenauigkeit im Verhältnis zu einigen Elastomeren.

Bandless impressions of tooth stumps obtained with the model materials Begolith, Dentaloc, Tewestone, Impredur and Keramid-Cement in combination with the elastic impression materials Silcoflex, Sanal/Silcoflex, Xirux/Xirux F and Impergum were studied in relation to dimensional behavior and reproduction fidelity. With reference to these parameters as well as to the hardness and abrasive behavior of the model materials after processing at various temperatures, recommendations are made for the optimum combination of these two groups of materials in practice.

[Various aspects of the prosthetic after care of patients with clefts]. / Aspekte der prothetischen Nachsorge des Spaltträgers.

The success of the prosthodontic treatment of cleft patients depends not only on the type and the extent of the defect and on the result of the surgical intervention and of the orthodontic early treatment, but also on a purposive orthodontic-prosthodontic pretreatment. The fundamental aim is to preserve the teeth and to create favourable static and aesthetic prerequisites for the definitive therapy. Splinting measures, mainly fixed dentures, are used for stabilizing the remaining dentition, with due regard to the morphologic conditions.

[Experimental studies of various model materials. 1. Comparative study on linear dimension behavior]. / Experimentelle Untersuchungen an verschiedenen Modellmaterialien 1. Mitteilung: Vergleichende Untersuchungen zum linearen Dimensionsverhalten.

The linear dimensional behaviour of the model materials Begolith, Dentaloc, Tewestone, Impredur and Keramik-Cement was investigated at various mixing temperature, the thickness of layer ranging from 3 to 5 mm. It seems that the model materials Begolith, Dentaloc and Tewestone will yield good results in practice. Impredur may be recommended on certain conditions. On the contrary, Keramik-Cement is not suited as a model material.
