Facial clefts are considered as predominant malformations of the oro-facial sphere due to their frequency, aesthetic and functional repercussions. 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 and involves temporary, mixed, and permanent dentition.The aim of this article is to review the place of dentofacial orthopaedics in the therapeutic calendar of facial cleft management.

Abstract Since turn of the 20th century orthodontic diagnosis and treatment planning has been based on the Angle paradigm that considers ideal dental occlusion ‘nature's intended ideal form’. The orthodontist's task is to seek balance between the patient's aesthetic demands, functional efficiency and structural harmony. The soft tissues largely determine the limitations of orthodontic treatment, from the perspectives of functions and stability, as well as aesthetics. Therefore orthodontist must plan treatment within the patient's limits of soft tissue adaptation and soft tissue contours. This is a case report showing a well finished case keeping in mind the emerging soft tissue paradigm in diagnosis and treatment planning.

The objective of this review was to analyze the process of wear of implants leading to the shedding of titanium particles into the peri-implant hard and soft tissues. Titanium is considered highly biocompatible with low corrosion and toxicity, but recent studies indicate that this understanding may be misleading as the properties of the material change drastically when titanium nanoparticles (NPs) are shed from implant surfaces. These NPs are immunogenic and are associated with a macrophage-mediated inflammatory response by the host. The literature discussed in this review indicates that titanium NPs may be shed from implant surfaces at the time of implant placement, under loading conditions, and during implant maintenance procedures. We also discuss the significance of the micro-gap at the implant-abutment interface and the effect of size of the titanium particles on their toxicology. These findings are significant as the titanium particles can have adverse effects on local soft and hard tissues surrounding implants, implant health and prognosis, and even the health of systemic tissues and organs.

Abstract Background The choice between extraction and expansion treatment is an endless debate in orthodontics. Ethnic and secular variations showed that there was a change in  arch perimeter over the last 50 years. Accordingly, the purpose of this study was to investigate the relation between the arch perimeter and the intercanine and intermolar widths in normal occlusion. Also, to design regression equations for the prediction of the arch perimeter based on arch width, in a sample of the Egyptian population. The images of 340 cast pairs for 11 to 13-year-old patients were traced using TracerNet. Intercanine width, intermolar width and arch perimeter were measured, statistical analysis was performed and regression equations for both arches were formulated. Results There was a positive correlation between the lower arch AP, ICW and IMW and between the upper arch AP and ICW. Lower arch perimeter = 0.536 I33 + 71.642, lower arch perimeter = 0.828 l66 + 58.604 and upper arch perimeter = 1.988 U33 + 30.492 were the significant derived equations. Conclusions The formulation of regression equations offers a tool for the prediction of arch perimeter or arch width that can act as a guide in diagnosis and treatment planning.

Analysis of sagittal jaw relationship is important in orthodontic diagnosis and treatment planning, and can be investigated by angular or linear parameters. In the present study an analysis was performed using profile cephalograms of 40 children with skeletal Class II malocclusion. A correlation analysis is presented, involving five different methods of expressing sagittal jaw relationships. Whilst some degree of agreement could be noted, it was not possible to suggest a pair of measurements, which in combination, could give a more accurate picture of sagittal jaw relationships.
