A Computerized Study Of Midpalatal Suture Expansion, Clelan G. Ehrler

Loma Linda University Electronic Theses, Dissertations & Projects

An investigation has been conducted to consider the effects of midpalatal suture expansion on the cranial-facial complex. Nine patients were treated that had constricted maxillae. Data was obtained from frontal and lateral headplate radiographs which were taken at four intervals during treatment. The Rocky Mountain Data Systems diagnosis was utilized to interpret the radiographic data.

The data from the nine cases were averaged to obtain a composit [sic] change at each of the four times.

Examination of the lateral headplate data revealed that no permanent significant alteration occurred to the positions of the mandible or maxilla in a vertical or …

The Relationship Of The Bucco-Lingual Position Of The Mandibular First Molar To Occlusion And Arch Stability, Lothar M. Guttschuss

Loma Linda University Electronic Theses, Dissertations & Projects

Forty non-treated and twenty-two orthodontically treated cases were selected to determine the relationship of the bucco-lingual position of the mandibular first molar to occlusion and arch stability.

Plaster models and occlusal radiographs were obtained from all the cases. Anterior crowding, intermolar width, molar classification, and molar overhang relative to the basal bone were determined. The modified technique for occlusal radiographs used was found to result in radiographs which were more versatile and accurate when interchanged with the model measurements. Clinical applications of this technique include the determination of root angulations, location of impactions, and the fabrication of individualized preformed arch …
