Growth defects in unrepaired unilateral cleft lip and palate

Photographs of dental casts or digital models: rating dental arch relationships in bilateral cleft lip and palate

“…A reliable method for evaluating and comparing treatment outcomes, in particular dental arch relationships, is essential. For patients with a unilateral cleft lip and palate (UCLP) several scoring methods have been described 4,6,9,10,13 . Two of these methods have been modified for patients with a complete bilateral cleft lip and palate (CBCLP) 5,12 .…”

Position, shape, and dimension of the maxilla in unoperated cleft lip and palate patients: Review of the literature

“…The overjet was described with negative values by Spauwen et al (1993), normal values by Bishara et al (1976) and Crabb and Foster (1977), and with larger values by McCance et al (1990), who also found a narrower dentition, whereas Spauwen et al (1993) documented no hypoplasias.…”

“…Isiekwe and Sowemimo (1984) did not describe premaxillary rotations, but did mention a mediolingual rotation of the central incisors. A cross-bite situation was more frequently noted in the canine area by Innis (1962), Bishara et al (1976), Crabb and Foster (1977), and Spauwen et al (1993) and in the premolar, molar, and incisor areas by Isiekwe and Sowemimo (1984). A cross-bite without exact localization was reported by Bishara et al (1985) and McCance et al (1990).…”

“…The dental arch was assessed using the parameters of dental arch width and length, collapse of the dental arch, rotations, cross-bite situations, molar relations, overjet and overbite, as well as tooth width. The dental arch width in the molar area was described as normal by Crabb and Foster (1977), Spauwen et al (1993), andDerijke et al (1994), but Sidhu et al (1982) assessed it as slightly larger. Conversely, McCance et al (1990) found a narrowing in the dental arch width.…”

“…A narrower width was described by Derijke et al (1994), not only with the bicuspid teeth but also in the canine area. Crabb and Foster (1977), McCance et al (1990), and Spauwen et al (1993), i.e., all authors who commented on the dental arch width in the canine area, described a smaller dental arch width.…”
