Objective: To exam the pharyngeal airway dimensions in cleft lip and palate subjects and to compare them with controls before orthognathic surgery and to assess the need for orthognathic surgery for these cases.

Material and methods: Pre-orthodontic cephalograms of two hundred patients were used in this study. Twenty-one landmarks for sagittal pharyngeal airway and soft tissue measurements had been identified for each cephalogram. Patients were selected according to the specific inclusion criteria and divided into 2 groups according to the presence of cleft lip and palate.
The first group was Jordanian cleft lip and palate and consisted of 100 subjects (50 females and 50 males, age ranged between 5 and 12 years, mean age was 8.4 ± 2.4 years), and the second group was 100 controls without cleft lip and palate (50 females and 50 males, age ranged between 5 and 12 years, mean age was 8.7 ± 2.2 years). Independent t-test was used to detect differences between the two groups.

Results: Subject's pharyngeal airway dimensions were significantly narrower, in the lower airway thickness (PNS - AD1) (P= 0.000), upper airway thickness (PNS - AD2) (P= 0.000), total lower sagittal depth of the bony nasopharynx (PNS - Ba) (P= 0.000), posterior sagittal depth of the bony nasopharynx (Ptm - Ba) (P= 0.000), total upper airway thickness (PNS - H) (P= 0.000) .Furthermore, McNamara’s lower pharynx dimension (P= 0.007) when compared to control.
On the other hand, control group showed significantly longer soft palate (PNS – P) (P= 0.000), and wider in both thickness of tongue (TGH) and soft palate (MPT) with (P= 0.000). The tongue length (TGL) and hyoid bone position did not record any significant difference when compared to subject group.

Conclusions: Subjects had narrower pharyngeal airway dimensions when compared with the controls and this was not due to soft tissue hypertrophy but attributed to the smaller bony nasopharyngeal framework and skeletal deformations. Orthognathic surgery is indicated in cleft lip and palate population to correct skeletal discrepancies.

Cysts of the salivary system represent 5 to 6% of all pathologies of the salivary glands. This article reports the cases of 2 patients consulting for labial swelling and swelling on the right side of the floor of the mouth. , cystic enucleation has been performed; and the histologic examination was in favor of a mucoid cyst. The mucoid cyst mainly affects the accessory salivary glands, in all areas of the oral cavity, except the gingival mucosa. Its prevalence varies depending on the location. It is most frequently found in the lower lip.. These cysts are most often false cysts traumatic by salivary extravasation, rather than cysts by retention. The location of the lesion, history of trauma, rapid onset, variations in size, bluish color and consistency are the main important factors to consider before making a diagnosis. Surgical treatment is based primarily on complete enucleation of the cyst.

Joint compression is a frequent consequence of temporomandibular disorders (TMD). Indeed, temporomandibular joints (TMJ) can be exposed to micro or macro traumas during its different functions, but especially during parafunctions inducing changes in the different tissues. These changes can accumulate and form part of an adaptive response process that may eventually be overwhelmed. Displacements of the disc, perforations of the articular disc, reshaping of the ligament and joint surfaces may be the consequences of these excessive forces. These disorders, frequently encountered in our daily practice, are often accompanied by disabling TMJ pain, limitation of condylar and mandibular movements, and sometimes even auricular disorders.
Faced with such symptoms, and after a precise diagnosis has been established, a reasoned management is necessary. It consists of reducing the pressure within the TMJ and stabilizing the results obtained. Thus, the wearing of an occlusal decompression splint is particularly recommended. This work, illustrated by a clinical case, is intended to describe the therapeutic approach of TMJ compression.

The objectives of the secondary impression are to reinforce the physical phenomena of sustentation and retention thanks to models whose purpose is to preserve the osteo-mucosal supporting surfaces by registering the micro-reliefs and respecting the vascular elements.
This recording can be done according to a digital pressure under the control of the practitioner, or according to a physiological occlusal force under the control of the patient.
The aim of this work is to focus on the functional registration of the supporting surface under occlusal control, to define its indications and limits, and to develop a detailed therapeutic protocol of the prosthetic sequences when making the secondary impression under occlusal pressure in the case of completely edentulous.

Fibrous dysplasia is a congenital hereditary non-benign tumor in which normal bone tissue is replaced by fibrous nickname with immature osteogenesis. Its cranio-facial location can be manifested by deformities with aesthetic prejudice. Its evolution is slow and sometimes asymptomatic. The diagnosis is clinical, radiological and histological. In the deforming forms, the treatment is surgical and recurrences are to be feared.

The goal of this work is to provide osteotomy treatment for bilateral fibrous dysplasia.
We report the case of a 17 year old adolescent with bilateral mandibular dysplasia had been evolving for about ten years. This dysplasia was at the origin of a very unsightly prominent chin. The clinical diagnosis was confirmed by radiological and histological analyzes. The treatment consisted of a modulating osteotomy that restored the chin to its original architecture.

Key words: dysplasia, fibrous, osteotomy.

The proalveolie is an alveolar abnormality of the anteroposterior sense characterized by a vestibular version of more than three millimeters of the incisor-canine group and the alveolar bone. It can lead to complications, aesthetic and/or functional sequelae. The objectives of our study were to determine the epidemiological profile of proalveolie in our daily consultations, to list the clinical forms encountered and to describe our conditions of care. This was a descriptive prospective study conducted from January 1st to December 31st, 2016 in the Odonto-Stomatology and Maxillofacial Surgery Department of the Donka National Hospital, Conakry University Hospital. It involved 13 patients with one of the clinical forms of proalveolie. The prevalence of proalveolies compared to other registered orthodontic anomalies was 36%; 69% of our patients were female for a sex ratio of 0.44. Dento-maxillary dysharmony was the most associated abnormality (46.15%). Maxillary proalveolina accounted for 69.23% of cases. The predominant etiologic factors were digital sucking (30.76%), hypotonia of the orbicularis of the lips and lingual interposition were 23.09% each. The established treatment was orthodontic and surgical-orthodontic; evolution and duration of treatment depended on the patient's constant or non-HAWLEY port.

Introduction : The objective of this study is to assess the satisfaction and return that practitioners have of fixed prostheses made in dental offices in Burkina.

Material and methods : It is a cross-sectional survey that targeted all dental surgeons in Burkina. Data collection was carried out using a self-administered questionnaire. Each practitioner was interviewed for a single patient supported in a fixed prosthesis.

Results : The main reason for consultation was aesthetic and functional and 51.9% of practitioners systematically devitalize the crowning tooth. More than half of the patients (67.7%) were satisfied with their fixed prosthesis. This rate is significantly higher among practitioners (90.3%). The main complaints raised by the patients were occlusal (31.6%).

Conclusion : Practitioners' clinical and technical skills must be improved to meet the highest demands on the precision, function and esthetics of fixed prosthetic reconstructions.

Old unrestored partial edentulous induces occlusal perturbations with functional and aesthetic damages. In metallic removable prosthesis, management of these problems requires a careful analysis and prosthetic project which visualizes the rehabilitation’s final result. The aim of this paper is to present the interest of pre-prosthetic analysis, prosthetic project and transitional prosthesis in aesthetic and functional partial edentulous’s rehabilitation. Biomechanical management of the metallic removable partial denture (RPD), using retention devices such as axial attachments, is an interesting and conservative option in cases of reduced periodontium.
