Orthognathic surgery – maxilla (Le Fort I, II and III)
John Dudley Langdon, Mohan Francis Patel, Robert Andrew Ord, Peter Brennan in Operative Oral and Maxillofacial Surgery, 2017
When the maxilla needs to be separated into three pieces, similar cuts are performed in the back of the hard palate and then, in addition to connecting to osteotomies across the midline of the hard palate, the cuts are extended laterally to finish, most often, between the upper canines and the lateral incisors on each side. To avoid damage to the teeth adjacent to the planned osteotomies, it is necessary to have the roots orthodontically diverged prior to surgery. It is not necessary to have a diastema between the crowns.
Radiosurgical Techniques
Jeffrey A Sherman in Oral Radiosurgery, 2020
A 10-year-old male was referred to the office for removal of a broad maxillary frenum. After a clinical examination and consultation with the orthodontist, it was decided that the frenectomy would facilitate orthodontic closure of the diastema.
Oral Problems Associated with Gastrointestinal Disease
John F. Pohl, Christopher Jolley, Daniel Gelfond in Pediatric Gastroenterology, 2014
The persistence of maxillary attachment during dental eruption may cause widely spaced central incisors (diastema). The extension of the mandibular frenulum to the interdental papilla may produce periodontal disease and bone loss.
Does dental appearance affect employment prospects: a prospective cross-sectional study

The findings of the current research contrast with those of Pithon et al. (2014) who report that those people with ideal dental aesthetics were evaluated as superior with respect to intelligence and likelihood of being hired, when compared to the same subjects with non-ideal dental aesthetics. These discrepancies may be attributed to differences in the methodology of these two studies. In the earlier study, the photographs were presented in their original size, on a 42-inch monitor placed 50 cm from the participants. In contrast, the photograph attached to the CV in the present study was relatively small (7× 4.8 cm) and was reportedly ignored by numerous participants. Despite the limitations of simply showing a picture, the dental appearances shown in the larger photographs would be more obvious, and less likely to be ignored by participants. Furthermore, the malocclusions in the first study included a midline diastema, crowding, prominent incisors and an anterior open bite, which are different to the dental appearances tested in this study.

She is the mother of patient 1 (individual II.4, Figure 1A). She was diagnosed with bilateral congenital cataracts at 4 years of age that were surgically treated, and had multiple dental alterations including diastema that required orthodontic treatment. At present, she is 36-years-old, has a long narrow facies, broad forehead, long nose, prominent nasal bridge, bulbous nasal tip, thin lips, anteverted pinnae, and normal fingers. The ophthalmological evaluation showed bilateral aphakia and microcornea, as the right horizontal corneal diameter was 7 mm on the right eye and 6 mm on the left eye; the visual acuity test demonstrated that she only perceives shadows. Her cephalometric study showed a skeletal class III with a negative relationship between the maxilla and mandible. The sella-nasion plane indicated a concave side face. The angle between the long axis of the lower incisor and the mandibular plane showed a dentoalveolar maxilar and mandibular retroinclination, with maxillar and mandibular retrusion. The clinical and panorex dental analyses indicated convergent lateral incisors, lateral worn-out teeth (which previously had a conical shape) (Figure 1G and H). The ears were anteverted. Clinical photographs, cytogenetic, and molecular studies of the patients were performed with informed consent.
Successful and stable orthodontic camouflage of a mandibular asymmetry with sliding jigs

Pretreatment facial analysis revealed mild facial asymmetry with the mandible deviated 3 mm to the right, passive lip sealing and 100% of the maxillary incisors displayed upon smiling. The aesthetics of his smile was compromised due to the 2 mm diastema between his maxillary central incisors and the cant of his upper occlusal plane, which led to a greater exposure of his posterior teeth on the right side. The profile was slightly concave with a deficient midface and normal nasolabial angle (Figure 1).
