Posterior Maxillary Surgery: Its Place in the Treatment of Dentofacial Deformities
Niall MH McLeod, Peter A Brennan in 50 Landmark Papers every Oral & Maxillofacial Surgeon Should Know, 2020
Four indications for posterior maxillary surgery were described: Posterior maxillary hyperplasia with an open bite and satisfactory lip-to-tooth relationship and increase in lower anterior face height.Total maxillary alveolar hyperplasia, with an increase in vertical dimension and maxillary protrusion.Bilateral or unilateral maxillary crossbite, which may exist in isolation as the only dentofacial deformity or in combination with other deformities such as cleft.Distal repositioning of the posterior maxillary alveolus to create space for an unerupted maxillary canine or premolar.
Alveolar bone grafting in cleft patients
John Dudley Langdon, Mohan Francis Patel, Robert Andrew Ord, Peter Brennan in Operative Oral and Maxillofacial Surgery, 2017
The principal concerns about very early bone grafting have been the potential harmful effects on maxillary growth. However, a further concern is that while the early bone graft will often produce a good repair of the alveolar cleft, by the time the permanent dentition adjacent to the cleft is erupting (especially the permanent maxillary canine tooth) between 7 and 12 years of age +, commonly the bone in the alveolar cleft is of insufficient volume to support those erupting teeth and a further ABG procedure needs to be considered. The same criticism has been levelled at early periosteoplasty.
Dental Anatomy and Occlusion
Jeffrey R. Marcus, Detlev Erdmann, Eduardo D. Rodriguez in Essentials of CRANIOMAXILLOFACIAL TRAUMA, 2014
The position of the cuspids or canines during occlusion has also been used to describe a proper relationship between maxillary and mandibular dentition. When the first permanent molars are in a class I relationship, the mandibular canine occludes mesial to the maxillary canine in the embrasure between the maxillary canine and lateral incisor (see Fig. 4-10, A).
Pain, discomfort, and functional impairment after extraction of primary teeth in children with palatally displaced canines – a randomized control trial comparing extraction of the primary canine versus extraction of the primary canine and the primary first molar

The children in this study were recruited between 2013 and 2018 among patients referred for orthodontic treatment at a public dental specialist clinic in Tromsø, Norway or in a private orthodontic clinic in Bryne, Norway. The inclusion criteria were: (1) chronologic age between 9.5 and 14 years; (2) dental age of 9.5–10.5 years [13]; (3) the presence of both primary maxillary canines and primary maxillary first molars; (4) palatal position of the canine verified by two periapical radiographs; and (5) eruption of the maxillary canine in sectors III and IV according to Lindauer et al. [14] or the maxillary canine in sector II with an angle between the long axis of the canine and the facial midline (Angle C) of at least 25 degrees assessed on panorama radiographs, according to Hadler-Olsen et al. [15]. The exclusion criteria were: (1) agenesis of the maxillary lateral incisor; (2) previous orthodontic treatment; (3) any disease not allowing local anaesthesia or extraction; or (4) the presence of craniofacial syndromes, cleft lip or cleft palate, odontomas or cysts. The treating orthodontist informed patients who fulfilled the inclusion criteria and their legal guardians about the study and invited them to participate.
Incidence of impacted teeth requiring fenestration, traction, and orthodontic treatment in Japan

Among all the dental institutions, the highest incidence of impacted teeth was observed in the maxillary canine region (435 [24.0%] and 411 [22.7%] teeth in the right and left quadrants, respectively) followed by the central incisor region (113 [6.2%] and 112 [6.2%] teeth in the left and right quadrants, respectively), and second premolar region (70 [3.9%] and 65 [3.6%] teeth in the left and right quadrants, respectively). In the mandible, it was particularly high in the second molar region (70 [3.9%] and 55 [3.0%] teeth in the right and left quadrants, respectively) followed by the second premolar region (47 [2.6%] and 42 [2.3%] teeth in the left and right quadrants, respectively) (Table 1). Impacted supernumerary teeth were the commonest (52 teeth) in the maxillary midline region.
Delayed diagnosis of displaced and impacted canines – a prospective longitudinal study

To avoid delayed diagnoses of impacted canines, clinical guidelines have been developed for the GDP, who has the responsibility for diagnosing eruption disturbances, to facilitate interceptive treatment and to perform the follow-up and, if needed, to refer the patient [14–17]. Clinical guidelines may differ between countries but also within the country. For instance, in the United Kingdom it is recommended that the eruption of the maxillary canine to be investigated by the age of 10 years and all patients with an impacted canine should be referred by the age of 12 [14]. Maxillary canines erupting after 12.3 years in girls and 13.1 in boys are considered late in their eruption [18]. Similar recommendations are also found in Sweden, where some county councils recommend that the canines should be monitored by palpation by the GDP every year from the age of nine. If no bulge can be noted, a new examination is recommended within a year. If an eruption disturbance is suspected, radiographs should be taken to determine the position of the canine. At 10 years of age, the position of the canines should be confirmed. However, if the patient’s tooth exfoliation happens early, radiographs should be taken earlier [15–17,19]. Other counties have clinical guidelines with recommendations that the GDP should make a risk evaluation at different dental developmental stages, according to Björk and Krebs [20].
