Keratocysts, also known as keratocystic odontogenic tumors (KCOT), make up 7% of all odontogenic cysts and develop asymptomatically in most cases. Enucleation is the benchmark treatment. However, there are surgical alternatives. Marsupialization and decompression are necessary in some cases, mainly when the KCOT is large, thus causing an increased risk of bone fracture, or if it has engulfed important elements such as the inferior alveolar nerve or teeth, consequently causing alveolar bone growth failure. The authors describe the case of a nine-year-old child treated for a large keratocyst situated in sector 4 (lower right jaw), impacting both premolars and the canine (45, 44 and 43)...

OBJECTIVE: The aims of this study were to determine the cephalometric norms in a Lebanese population of young adults, to find the differences in cranio-facial morphology between males and females and to establish the equivalency between conventional measurements and those based on the true horizontal. MATERIALS AND METHOD: Ninety subjects divided into 43 women and 47 men, aged from 18 to 30years, were selected based on specific criteria. The lateral cephalograms were taken in the natural head position...

In a private practice, between January 2010 and December 2015, 621 impacted teeth were exposed for orthodontic purposes. The majority were maxillary canines (464=74.71%), followed by maxillary central incisors (36=5.80%), mandibular canines (32=5.15%) and, finally, second premolars (30=4.83%). The 464 maxillary canines were present in 356 patients with a mean age, at the time of the intervention, of 15 years and 3 months (7 years and 10 months to 45 years and one month). The gender distribution was 60.7% (F) to 39...

Facial asymmetry requires multidisciplinary management. In some cases, predictable problems due to congenital abnormalities can be corrected by early orthodontic treatment. Orthodontics is nevertheless often part of an orthosurgical treatment plan. The solutions are conventional and familiar: maxillomandibular rotation osteotomy and genioplasty. Many cases can be treated in this way, but there is often persistent residual asymmetry due to loss of volume that is not corrected by these techniques. The use of maxillo-acial endoprostheses designed on the basis of three-dimensional craniofacial analyses can rebalance volumes simply and with due regard to the patient's anatomy...

Date of birth: 12/10/1987; sex: female. A. PRETREATMENT RECORDS: 24 years 8 months; 16/06/2011. DIAGNOSIS: Skeletal and dental Class I, maxillary endognathia, anterior vertical excess with open bite; teeth missing prior to treatment: 18, 28, 38, 48. TREATMENT PLAN: Appliances and devices: single-stage surgical-orthodontic treatment using pretorqued and preangled bimaxillary multibracket appliances with 0.022×0.028″ archwire, along with an expander during the surgical phase and then a transpalatal arch to stabilize the transverse correction...

The aim of this work was to model tooth movement in a more clinically-exact fashion, thanks to the use of new IT tools and imaging systems (cone-beam). Image segmentation and 3D reconstruction now enable us to model the anatomy realistically, while finite element (FE) analysis makes it possible to evaluate stresses and their distribution on the level of the tooth, the periodontal ligament (PDL) and the alveolar bone when a force is applied. The principle is to monitor tooth movement by obtaining optical impressions at each stage of treatment...

Mandibular advancement devices (MAD) are recommended in certain cases for the treatment of obstructive sleep apnea and hypopnea syndrome (OSAHS). The aim of this study was to make a retrospective investigation into the dental and skeletal effects in patients suffering from OSAHS after wearing an MAD, and according to the type of device, rigid or semi-rigid. Cephalometric criteria on lateral cephalograms before and after at least 6 months of treatment were analyzed. Twenty-two patients were included. We observed average labial tipping of the lower incisors (+4...

OBJECTIVE: To investigate the effect of a cross-linking agent on the mechanical properties of self-cured orthodontic acrylic resin using PMMA powder (CPM-PMMA) with a compromised microstructure. MATERIALS AND METHODS: The mechanical properties of three sample groups were investigated in this study: CPM-PMMA, orthocryl and orthoplast. CPM-PMMA powder was prepared by suspension polymerization. It was mixed with a commercially available liquid (orthocryl) to yield a test specimen and to compare its flexural properties and Vicker hardness with the two commercial products...

OBJECTIVE: The purpose of this study is to evaluate the postretention stability of the dental arches in Class II division 1 patients treated with four bicuspid extractions and the edgewise technique. MATERIALS AND METHODS: A digital caliper was used to analyze the dental casts from 29 Class II division 1 malocclusion patients with skeletal type II (14 males, 15 females; ages ranging from 10.2-18.0 years), treated with four bicuspid extractions and the edgewise technique...

PURPOSE: A 13-year-old male patient, presenting a Class II, division 1 malocclusion and crowding was treated by an innovative technique. METHODS: After rapid palatal expansion by a Hyrax appliance, the teeth were bonded with straightwire brackets. Two miniscrews were inserted, one per side, in the mandibular buccal bone between the roots of the mandibular first molar and the second premolar. On the right side, the miniscrew implant was connected to the hook clamped on a 0...
