Introduction:In orthodontics, apart from essential diagnostic aids, there are so many soft tissue analyses in which lips are major part of concern. However, lip prints have never been used in orthodontics as diagnostic aid or forensic tool. Therefore, this study was designed to explore the possible association of lip prints with skeletal malocclusion.Materials and Methods:A sample of 114 subjects in the age group of 18-30 years, from North Indian adult population were selected on the basis of skeletal class I, class II and class III malocclusion, each comprising of 38 subjects with equal number of males and females. Lip prints of all the individuals were recorded and digital soft copies of lateral cephalograms were taken. Lip prints were compared between different skeletal malocclusions.Results:It was found that branched lip pattern was most common in North Indian adult population with no sexual dimorphism. The Z-test for proportion showed that the prevalence of vertical lip pattern was significantly higher in subjects having skeletal class III malocclusion.Conclusion:A definite co-relation of vertical lip patterns with skeletal class III malocclusion was revealed.

Introduction:The success behind orthodontic diagnosis and treatment planning lies in appropriate evaluation of the patient's soft tissue profile appearance.

Since the earliest days of the specialty, Orthodontists have sought to avoid the reciprocal nature of forces. This quest has fostered many schemes that purport to defy the physical realities of Newton's Law. The term "anchorage" is usually applied to the resistive value of the posterior teeth to a force that would produce mesial tooth movement. The mechanism by which these retroactive forces are countered is known as "anchorage control".The anchorage value of posterior teeth in the antero-posterior and vertical direction appear to be higher in lingual orthodontics (than in labial orthodontics) as the forces applied to the anterior teeth are lingual to the center of resistance and distally rotating forces on molars are constantly applied during en-masse retraction. This paper presents a case report of a 30 yrs old male patient with Class I Bimaxillary Protrusion treated using innovative lingual forces with a labial appliance (without any additional intraoral or extraoral anchorage devices) effectively with negligible anchorage loss.

ObjectiveThe purpose of the modified repositioning appliance was to overcome the shortcoming of existing design for repositioning protruded premaxilla in a child with bilateral cleft lip and palate.MethodsThe basic principles of design were similar to Latham’s appliance but the surgical pinning of premaxillary segment was avoided and instead acrylic splint was prepared.ConclusionsThis technique avoids any invasive procedure, is useful to reposition protruded premaxillary segment in bilateral cleft lip and palate cases specifically in child who reports late with deciduous dentition.
