Cleft lip and palate management with maxillary expansion and space opening for a single tooth implant
摘要:
An adult Class I malocclusion with a unilateral cleft lip and palate is presented. The maxillary transverse deficiency was managed with orthopedic expansion and the missing lateral incisor with space opening, bone grafting, and single tooth implant. The mild maxillary retrognathia and deficient lip support was managed with dental compensation.

An efficient and highly versatile method for the synthesis of diverse regiospecific 1-arylbenzotriazoles being important medicinal scaffolds, by the copper (1) catalysed intramolecular N-arylation of diazoaminobenzenes of 2-haloaryldiazonium salts in PEG-water has been developed. A very simple reaction protocol, large number of substrate affordability and excellent yields are the main features of this methodology.
