Presurgical orthopaedic treatment using hard plates

Nasolabial and alveolar morphology following presurgical orthopaedic treatment in complete unilateral clefts of lip, alveolus and palate

“…Furthermore, good morphological results involving not only alveolar but also nasolabial form, can be achieved by presurgical orthopaedic treatment (Hotz and Gnoinski, 1976). While the effect of orthopaedic treatment on alveolar form has been previously described (Huddart, 1979;Weil, 1987;Hochban and Heinz, 1989;Mishima et al, 1996; Nasolabial and alveolar morphology 345 Kozelj, 1999), the influence of orthopaedic treatment on facial form has not been quantitatively investigated.…”

“…The efficacy of the Hotz's plate in the improvement of feeding, growth and configuration of the maxillary segments, has been previously described (Huddart, 1979;Weil, 1987;Hochban and Heinz, 1989;Mishima et al, 1996;Kozelj, 1999). Few reports, however, have addressed the effects of this device on nasolabial form.…”

Presurgical Orthopedic Treatment Ameliorates Postoperative Nasal Deformity After Cheiloplasty

“…The HP is applied to maintain or improve the dental arch form, and to control the effects of surgical lip closure. 1,2 It encourages a passive orthopedic guidance of maxillary growth 3 and importantly, prevents the tongue from slipping between the cleft segment. 4,5 Furthermore, continuous use of the HP until the time of palatoplasty seems to be effective for improving postoperative articulatory function.…”

Longitudinal Study of Effect of Hotz's Plate and Lip Adhesion on Maxillary Growth in Bilateral Cleft Lip and Palate Patients

“…Infant orthopedic treatment was first introduced by McNeil (1956) and was further improved by others (Hotz and Gnoinski, 1976, 1979; Huddart, 1979; Weil, 1987; Hochban and Heinz, 1989). It has been reported that appliances help guide the alveolar arch to an ideal form.…”
