    Notes: The redistribution of Fe and Ti implanted into InP and its recrystallization is studied using 〈m1;37.6p〉various thermal annealing techniques. Fe and Ti profiles are measured by secondary-ion mass spectroscopy and recrystallization by Rutherford backscattering channeling. Ti shows absolutely superior thermal stability under any circumstances as compared to Fe. Iron always accumulates at the surface and at a depth of approximately twice the projected range Rp. After high-dose implantation Fe additionally accumulates in the 0.8Rp region. At similar doses Ti still shows no diffusion and only faint accumulation between the surface and Rp.

    Description / Table of Contents: Summary A method of surgical support of a rapid maxillary expansion is described. Specific osteotomies are performed on the attached region of the maxillary zygomatic process and the dorsal and middle part of the hard palate. The results of 14 patients are demonstrated. Almost all patients underwent surgical correction of sagittal and/or vertical jaw relations after a subsequent harmonization. This surgical orthodontic expansion proved to be an efficient and low pain method of preoperative correction of transverse maxillary deficiencies and facilitated the following skeletal surgery.
    Notes: Zusammenfassung Eine Methode zur chirurgischen Unterstützung einer forcierten Gaumennahterweiterung wird beschrieben. Hierbei werden gezielte Osteotomien im Bereich der Ansatzstelle des Processus zygomaticus der Maxilla und des dorsalen und mittleren Abschnittes des harten Gaumens durchgeführt. Die Ergebnisse an 14 patienten werden exemplarisch dargestellt. Bei fast allen Patienten erfolgte nach anschließender Zahnbogenkoordination eine operative Korrektur der sagittalen und/oder vertikalen Kieferrelation. Die chirurgisch-orthopädische Gaumennahterweiterung erwies sich als effiziente und schmerzarme Methode zum präoperativen Ausgleich von transversalen Kieferdiskrepanzen und erleichterte das spätere operative Vorgehen.
