Material and Methods: An electronic search extending from 2012 to 2022, targeting mainly clinical trials was performed on the following databases PUBMED (MEDLINE), The Cochrane Library, SCIENCE DIRECT, EBSCO HOST DATABASES, and GOOGLE SCHOLAR. The search was established on a well-defined research question following the PICO principle: population, intervention, comparator, and outcome. Search evaluation and the assessment of the risk of bias (RoB) were undertaken in each study following its type and design. Results: Thirteen studies were included for qualitative analysis, with a low to moderate RoB. Ten studies used only heavy conventional palatal anchorage such as a fixed trans palatal arch (TPA), while one study used skeletal anchorage to manage the orthodontic traction ...

Objective: The aim of our study is to explain the important place of orthodontic therapies, whether orthopedic or surgical, in the multidisciplinary management of OSA and in the improvement of nasal breathing through a systematic review. Material and methods: A search of the literature was performed in the following databases: PubMed, ScienceDirect, Cochrane Library . The search was limited to publications written in English and French from 2010 to January 2022. Results: On the basis of the keywords, eighty-three references were initially identified. After the elimination of duplicates, the number of articles was reduced to seventy-nine. The study of the titles and abstracts made it possible to select fifty articles. Aft...

It is defined as a proclination of maxillary and mandibular incisors in relation to the skeletal bases, which results in labial biprotrusion and forced closure of the lips. This case report shows the orthodontic management of a young female patiente, who presented herself to the orthodontics department in Rabat for aesthetic consultation: maxillary protrusion and dental crowding.

In fact, even though craniofacial deformations are the result of both genetic and environmental factors, there is irrefutable evidence for the high genetic control on craniofacial development and for the significant genetic influence in many dental, occlusal and skeletal variables. The aim of this twin's case report is to clinically show the role of each of these two factors on the expression of abnormalities and particular traits. Case presentation: The case reflect 10-year-old twins who consulted for their anterior overlap. The comparison between the twins is done through clinical and cephalometric investigation. The clinical examination revealed a great resemblance between the two patients both at the extra-oral (ortho-frontal profil, nasolabial angle, the shape of the forehead, cervico-chin distance) and intra-oral view (Palatoposition of the maxillary lateral incisors, molar class I, mandibular arch perfectly identical with mirror effect), Cephalometric analysis revealed a very high morphological similarity (identical skeletal class III, biproalveolia, hyperdivergenc and the position of mandibular incisor). Conclusion: The existence of a very important genetic control on craniofacial development and the installation of dysmorphosis is undeniable, in particular on skeletal class III and hyperdivergence. But the severity of these dysmorphosis can also be increased by environmental and behavioral factors.

This study involved the participation of 127 untreated Moroccan adults from the patient population of the ODF (Dentofacial Orthopedics) Department at the Center for Dental Treatment and Consultation (CCTD) in Rabat. Full adult dentition was the only criterion for inclusion. Patients with major syndromes and patients with facial clefts were excluded from the study. For the purposes of this analysis, we used profile teleradiography to measure vertical and sagittal skeletal variables as well as vertical dentoalveolar variables in the anterior and posterior maxillary and mandibular regions. We also measured the incisor axes. Analyses and statistical tests were performed with SPSS(®) statistics software (version 9.5 for Windows). Results indicate that: (i) upper posterior alveolar height (UPAH) does not correlate with skeletal variables of facial divergence, but correlates strongly with anterior facial height (AFH) and moderately with posterior facial height (PFH); (ii) lower anterior alveolar height (LAAH) correlates negatively with facial height index (FHI), positively with the FMA and AFH, but does not correlate with PFH; (iii) lower posterior alveolar height (LPAH) does not correlate with skeletal variables of facial divergence; (iv) upper anterior alveolar height (UAAH) changes inversely with FHI, correlates positively with the FMA and does not correlate with PFH.

Cent vingt-sept patients adultes marocains non traités de la population consultante du service d’ODF du Centre de consultation et de traitement dentaire (CCTD) de Rabat ont participé à cette étude. Une denture adulte complète constituait le seul caractère d’inclusion. Les grands syndromes et les patients présentant des fentes faciales étaient exclus de l’étude. Pour réaliser cette analyse, nous avons mesuré sur les téléradiographies de profil les variables squelettiques du sens vertical et du sens sagittal, des variables dento-alvéolaires du sens vertical dans les régions antérieures et postérieures maxillaires et mandibulaires. Nous avons aussi mesuré les axes des incisives. Les analyses et les tests statistiques ont été réalisés sur le logiciel statistique SPSS® version 9.5 pour Windows. Les résultats indiquent que : (i) la hauteur alvéolaire postérieure supérieure (HAPS) n’est pas corrélée aux variables squelettiques de la divergence faciale, mais l’est fortement avec la hauteur faciale antérieure (HFA) et l’est moyennement avec la hauteur faciale postérieure (HFP) ; (ii) la hauteur alvéolaire antérieure inférieure (HAAI) est négativement corrélée avec l’index des hauteurs faciales (IHF), positivement corrélée avec l’angle FMA et la HFA, et ne l’est pas avec la HFP ; (iii) la hauteur alvéolaire postérieure inférieure (HAPI) n’est pas corrélée avec les variables squelettiques de la divergence faciale ; (iv) la hauteur alvéolaire antérieure supérieure (HAAS) évolue inversement de l’IHF, est positivement corrélée avec l’angle FMA et ne l’est pas avec la HFP.

To investigate and quantify the release of BPA from these retainers. Methods: Three types of orthodontic bond were selected randomly from the most popular orthodontic composites: Transbod XT, Master-Dent® Flow and Nanocomposite Proclinic Expert. Specimens were made using a metallic parallelepiped mold and polymerized for 20 seconds with an LED lamp. Each cured sample was immediately immersed in artificial saliva with different pH levels (7, 4, 2). Samples were analyzed at t0, t1 and t2 using a High-Performance Liquid Chromatography. Data were analyzed using a statistical package for social sciences. One-factor Anova and Anova for repeated measurements tests were used. A value of p less than 0.05 was considered statistically significant. Results: The analyses showed BPA release from Proclinic, although both Transbond XT and Master-Dent® didn't show any release of BPA in saliva (p>0.05). Release from Proclinic was influenced by the pH of medium (p<0.05) and the immersion time (p<0.05), thereby the more the pH decreased the more the amount of BPA increased (p<0.05) and as the immersion time increased the amount of BPA increased (p<0.05). The maximum amount of BPA reached from Proclinic was 0.680µg/ml and 1.032µg/ml at t2-Ph4 and t2-Ph2 respectively. Conclusions: The different amounts of BPA released from Proclinicremain relatively lower than the tolerable daily intake of BPA, but clinicians should be careful about the use of composites.

He was diagnosed with an asymmetrical anterior open‐bite, asymmetrical occlusion, unilateral crossbite, gummy smile, skeletal Class II pattern, loss of six molars, periodontal defect and restorative complication on the mandibular left first molar. He refused the surgical-orthodontic treatment option, although he wanted to correct the malocclusion. After periodontal treatment and initial alignment with Edgewise appliances .022” .028” and the Tweed technique, differential intrusion of anterior and posterior teeth, left and right side in max‐ illary arch was necessary to maximize the skeletal treatment effects using two mini‐implants as a temporary anchorage devices (TADs). These TADs were inserted at convenable areas on maxillary arch to allow reasonable biomechanics using archwires with accentuated curves of Spee. After a hopeful improvement of the malocclusion, extracti...

The management of patients with CLAP requires several repair procedures for the soft palate, the primary and secondary bony palate, the alveolar ridge, the lips and the nose. These patients often present with a maxillary transverse deficit responsible for maxillary endognathy which must be corrected for a harmonious development of the maxillomandibular complex. The objective of our work was to evaluate the efficacy of slow, rapid and surgical maxillary expansion in patients with sequelae of CLAP following a systematic review protocol. Materials and methods: Four databases were searched: PubMed / MEDLINE, ScienceDirect, Cochrane Library and EBSCOhost, using the keywords present in the MeSH according to the equation [Maxillary expansion] AND [Cleft lip and palate]. The selection of articles included all studies published since January 2010 and for which the full text is available, such as met...

The overall prevalence of cleft palates is estimated at 1 per 700 births in the general population, with 77% of isolated cases, 16% associated with another malformative pathology, and 7% associated with a known syndrome. They can disrupt soft tissues (upper lip, nasal threshold, nasal wing, palate veil), hard tissues (alveolar arch, dental germs, palate), or both.They constitute a congenital dysmorphosis for which the therapeutic management extends from birth to the end of adolescence. Orthodontic care has evolved considerably in recent years, mainly due to the synergy of the different specialities involved in the care of these children by the multidisciplinary team.These cleft lips and palates have a multifactorial and complex etiology requiring a multidisciplinary approach. Orthodontic treatment has a strategic place in this treatment a...

Method: five databases were consulted: PubMed; PubMed Central, Google Scholar, Cochrane Library, and Ebscohost. The research included published studies from 2010 to 2018, meta-analysis studies, randomized and non-randomized controlled trials, prospective and retrospective studies, case series, control cases. Results: Among the 299 selected references, only 4 studies met our inclusion criteria. There is no statistically significant difference in alveolar bone loss between the two closed and open techniques for palatal canine traction. Bone loss ranged from 0.03 mm to 0.39 mm compared to the contralateral normal canine. For vestibular traction, bone resorption compared to the normally located canine varies from 0.82 to 0.89 mm. Conclusion: Canine traction is accompanied by a statisti...
