Abstract: Presented is a prospective cohort study of 72 calcium phosphate coated Bicon Integra-CP implants for 18 patients with pronounced class V and VI maxillary atrophy according to the classification of Cawood and Howell (1988) and treated with four ultrashort 4.0 x 5.0 mm locking taper implants. The patients were divided into three groups. For the first group, four 4.0 x 5.0 mm implants were placed. For the second group, two narrow 3.0 x 8.0 mm implants were placed in very thin anterior alveolar bone. For the third group, the alveolar bone in the premolar and molar region was too narrow and too shallow; therefore, 4.0 x 5.0 mm implants were placed in the maxillary tuberosities. All implants were restored with TRINIA, a metal-free fiber-reinforced hybrid resin CAD/CAM material. Two patients lost one implant each during the observation period, which were subsequently replaced successfully. The cumulative one-year patient-based implant survival rate (CSR) was 88.8%. The cumulative one-year implant-based survival rate was 97.2%. Since the patients with a failed implant were able to wear their prosthesis with only three implants while the replacement implants were being osseointegrated, this resulted in 100% prosthetic success. The good result allows the conclusion that the long-term use of four ultrashort and narrow locking taper implants reveal a comparable outcome to standard size implants with complex bone augmentations.

Abstract: The purpose of this work is to describe the technique of double-stage genioplasty and to bring out its interest in the important retromicrogenia l and its feasibility in the context. The study provides a descriptive and cross sectional study with prospective data collection, conducted in the department of Maxillofacial and Aesthetic Surgery of the Mohammed 6 Teaching Hospital of Marrakech, on two patients who have benefited a double-stage genioplasty. These are two clinical cases of retromicrogenia. The first (patient1) is subject to temporo-mandibular ankylosis, and the second (patient2) is subject to congenital with growth disorders of the dental arch, a tendency to class-II skeletal patterns, pro-alveoli, swallowing problems, and occurrence of recurrent mouth infections due to poor oral hygiene. They were treated, respectively, with double-stage genioplasty only and a combined procedure of double-stage genioplasty associated with Wassmund osteotomy at the same time. The patients were female, young on average 24 years of age. The average duration of the intervention was 1h10 minutes; the mandibular advances were on average 8mm per fragment. The dental articulation and the projection of the chin were satisfactory. Retromicrogenia is a rare pathology, the source of functional and morphologic complications. “Double-stage” advancement genioplasty is the treatment of choice. It allows a necessary advancement for a good reflection of the chin, and remains a simple technique, minimal, and ensuring good aesthetic and functional results over the long term.

Abstract: Facial fractures are a worldwide health problem as they constitute a potential cause of functional and morphological disabilities and death. In elder patients more than in the younger, facial fractures expose to difficulties of treatment and risks of unfavourable outcome due to limited physiological reserves, osteoporosis, frequent defective dental status and underlying medical conditions. The aim of this study was to analyse facial fractures' frequency, aetiologies, gender distribution and treatment outcome in elder patients at a referral hospital in Burkina Faso. The medical records of patients with facial fractures and who were 60 years of age at least, during a 13 year-period, were retrospectively analysed. All the patients had clinical and radiological evidence of facial fractures. Surgical treatment of the facial fracture was performed by plates and screw system or by a 0.5mm-diameter soft stainless steel wire internal fixation which was always combined with jaws immobilization in patients with occlusal fractures. Out of 2400 facial fractures patients, 103 (4.3%) were 60 years old or over. Patients’ age ranged from 60 to 85 years and fractures' frequency decreased gradually with age. There were 107 males and 27 females (male to female ratio 3.9:1). The leading circumstance of trauma was road traffic crashes (87.3%) followed by far by interpersonal violence (7.8%). Nearly two third of facial fractures involved the midface with at first rank the zygomatic complex (45.7%) while mandibular fractures accounted for 29.1%. In 29 patients (28.1%), extra facial lesions were noted which consisted mostly in cranial trauma and limb fractures. There was a need of surgical treatment in 23 of the 103 patients (22.3%) but 7 patients (6.8%) declined this approach. Out of the 96 patients treated according to indication, 88 (91.6%) had an uneventful and satisfactory treatment outcome. Complications or unsatisfactory outcome comprised operative site infection, facial sensory disturbance, delayed bone union, diplopia, and temporomandibular joint dysfunction. The findings of this study command enforcement of road traffic security in Burkina Faso.
