Objective data are required for assessing the influence of movements of the tongue on the position of the teeth. Electromagnetic articulography (EMA) makes it possible to track movements of the tongue using the principle of inductive distance measurement. A helmet made of light but robust acrylic material serves as a carrier for three transmitter c...

During orthodontic-surgical treatment of dentofacial deformities, centric relation of the mandibular condylar head to the fossa articularis must be maintained. Intraoperative application of the condylar positioning appliance, in combination with different surgical splints, allows three-dimensional adjustment of the jaw segments. The condylar positi...

The care of patients with cleft lip, alveolus, and palate demands supervision of the development and progress over a long period of time. It also requires a standardized and systematic basic documentation. In our cleft center the documentation is summarized on one sheet of paper with DIN-A4 formation (297 x 210 mm). The use of electronic data proce...

In orthognathic surgery a three-dimensional positioning of the maxilla is possible by means of the Le Fort I osteotomy and subsequent maxillary movement. In treatment planning and at the time of surgery it is very important to achieve an exact positioning of the upper incisors in relation to the upper lip and the rest of the skull. The Model Positi...

A prospective follow-up study of 21 class-II patients, who were treated with a combination of orthodontics and orthognathic surgery, revealed typical postoperative changes in opening mobility. Their characteristics were: a strong initial loss of mobility and a regeneration period of about one year. Because the increase of mobility could not complet...

Eine prospektive Verlaufskontrolle von 21 Patienten mit Klasse-II-Anomalie, die in gleicher Weise kieferorthopdisch-kieferchirurgisch behandelt worden waren, zeigte als wesentliche Merkmale postoperativer Vernderungen der ffnungsmobilitt einen starken initialen Mobilittsverlust und einer Regenerationsphase von etwa einjhriger Dauer. Da die Zunahmen...

Resection affecting the continuity of the mandible and the mandible nerve leads to complete anaesthesia of the lower lip and mental area, furthermore to deformity and functional disturbance like uncontrolled salivation. In our long term follow up study on multimodal neurological investigation sensibility is reported to have uncomplete regenerated s...

Commonly, only radiographic procedures have been used up to now for the assessment of intraoral movements during swallowing, speech and voluntary motor activities. In this article two methods for assessing intraoral function without involving radiation exposure are described: palatography and electromagnetic articulography. Palatography is particul...

The examination of tongue motor functions requires a clinical examination of voluntary movements as well an objective evaluation of the intraoral movements during speech, deglutition, mastication and during rest. For a comparison with the simple visual assessment of voluntary movements with the mouth opened, intraoral tongue movements have been stu...

A new technique for positioning control in Le Fort I osteotomies is presented. This intraoral procedure allows three-dimensional positioning of the condyles in the desired centric or therapeutic relation and of the maxilla at the same time. It combines the intraoperative use of the "Condylar Positioning Appliance" with the "3D Doublesplint Method".

A new method for positioning the maxilla and condyle after Le Fort I osteotomy maintains the patient's vertical dimension (ie, the relation of the mandible to the skull above the osteotomy plane) in the preoperative and postoperative positions during both cast surgery and actual surgery. During surgery the condylar positioning appliance is fixed to...

The Le Fort I osteotomy can be used to change the position of the maxilla in all three dimensions. A presurgically fabricated occlusal splint is used to reproduce the planned sagittal and transverse position of the maxilla. Various methods for determining the proper vertical position have been described. The major difficulty in vertical control whe...

Hydroxylapatite is commonly used for augmentation of the atrophic alveolar ridge. A new surgical technique is described for HA-augmentation and simultaneous vestibuloplasty on the severely atrophic jaw. The open surgical technique includes a lingually based mucoperiostal flap, the implantation of Hydroxylapatite particles in a vicryl mesh and the u...

It has been shown that electronic axiographic tracings of patients 2.5 months after a surgical advancement of the maxilla by Le-Fort-I osteotomie changed only slightly in comparison to preoperative tracings. The sagital opening path as well as the sagital protrusive path showed alterations in curvature. On the other hand sagital split osteotomie wi...

The presented anamnestic sheet with its detailed subcategories is the basis for a computer-aided documentation system for longterm follow-up of patients with lip, alveolar, and palatal clefts. The expected result is a reduction of later treatment requirements.

Explains the background of a movement to weaken vocational agriculture programs in Texas. Describes the efforts of alumni and current members of Future Farmers of America to change vocational agriculture's image; these efforts have turned public opinion and enabled educators to help reshape the agricultural education curriculum.

In der interdisziplinären Sprechstunde für Patienten mit Lippen-Kiefer-Gaumenspalten (LKG) erfolgt nach Entwicklung eines geeigneten Dokumentationsbogens seit kurzem die Dokumentation der Befunde und übriger Daten mittels eines Personal-Computers (PC- System). Dies stellt eine Weiterentwicklung des anderenorts bewährten Lochkarten- Systems dar und...
