Assessment of Efficacy (Time Taken During Stage I and Pain Perception) of Customized Lingual Orthodontic System
Introduction: To assess of the efficacy of customized lingual orthodontic system (IncognitoTM 3M Unitek), during initial aligning and Levelling based on time factor and also to assess patient‟s discomfort during initial aligning and Levelling. Methodology: 12 patients between age group of 15 – 26 years with mild to moderate crowding based on Little‟s irregularity index, in upper and lower arches which were bonded with IncognitoTM Appliance System. Results: The average rate of initial aligning and levelling for all patients is 0.0361mm/ day. When time taken for initial aligning and levelling in both the arches was compared, it was seen that time was more for maxilla than mandible but it was statistically insignificant. Conclusion: Majority of patients reported, eating and having hot drinks aggravated pain while lying down, medication, sleep and having cool drinks relieved pain. 83.33 % of patients described the overall pain experience as mild.
Concentrated Growth Factor (CGF) in Alveolar Bone Grafting Procedures: Dilemma or Reality? – A Commentary
Alveolar bone grafting is considered to be one of the most challenging task in the management of cleft lip and palate patients as it is expected to bridge the gap between the alveolar segments and provide the solid base for the un-erupted tooth/teeth to erupt through it, besides effectively healing the Oro-antral fistula if any passing through the cleft into the nasal cavity. Although the traditional approach is to use autogenous bone graft from iliac crest, which has its own side-effects like pain, morbidity, additional surgery, etc. However with the advent of Tissue engineering technique, it has become possible to overcome most of these challenges by using a tissue friendly yet innovative material by name CGF (Concentrated Growth Factor) which in reality is the latest version of platelet-rich plasma having in it abundant of growth factors thereby serving the purpose of a regenerative medicine, wherein three factors are important to stimulate the bone regenerative effect: 1) Scaffold 2) Growth factors and 3) Autologous cells. All these are found to be present in sufficient quantity in CGF which was first introduced by Sacco in 2006 followed by Corigliano in 2010.
