3-Dimensional Evaluation of Two PNAM Techniques (Modified Grayson & AlignerNAM) on Facial Soft Tissue Morphology: A Randomised Clinical Trial.

OBJECTIVE: Evaluate facial changes after Presurgical Naso-Alveolar Molding (PNAM) in unilateral cleft lip and palate (UCLP) patients treated with Modified Grayson Technique and AlignerNAM (with DynaCleft nasal elevator) using a 3D facial scan. DESIGN: Randomised clinical trial. SETTING: Institutional study. Participants: 20 UCLP patients allocated to two groups (10 patients each). INTERVENTIONS: Group A patients underwent PNAM with Modified Grayson Technique and Group B patients underwent AlignerNAM (with DynaCleft nasal elevator). Their 3D facial scans were obtained by using an iOSbased application (Bellus3D FaceApp) mounted on a novel frame. These .stl files were analysed using 3D software (GOM INSPECT) at three-time intervals; before intervention (T0), after intervention (T1) and one month after lip repair surgery (T2). MAIN OUTCOME MEASURE(S): Changes in facial and nasolabial morphology. RESULTS: Both techniques brought significant improvement in the columellar length, nasal tip projection, columella angle, nasal tip angle and a significant reduction in cleft width. At T1, a statistically significant difference in angular and linear measurements was present in both groups. At T2, no statistically significant difference in linear parameters was observed between the two groups except for the outer lateral height of the non-cleft side, basal lateral height of the non-cleft side, and philtrum width. Similar pattern was observed in angular measurements with no statistically significant difference between the two groups except in nasolabial angle, anterior nasal base triangle III, and anterior nasal root triangle. CONCLUSIONS: Aligner NAM and Modified Grayson technique are equally effective PNAM methods with similar clinical results in nasolabial morphology after lip repair surgery.

Effect of micro-osteoperforations on the rate of orthodontic tooth movement and expression of biomarkers: a randomized controlled clinical trial.

INTRODUCTION: Micro-osteoperforation is a minimally invasive technique that has been used to accelerate orthodontic tooth movement and reduce treatment duration. However, literature presents conflicting reports about this technique. OBJECTIVE: To evaluate the effectiveness of micro-osteoperforations on the rate of canine retraction and expression of biomarkers in gingival crevicular fluid (GCF). METHODS: This was a randomized clinical trial with split-mouth study design. Thirty adult subjects with age above 18 years (20.32 ± 1.96) who required fixed orthodontic treatment and extraction of maxillary first premolars were enrolled and randomly allocated to either the experimental or control group. Randomization was performed by block randomization method, with a 1:1 allocation ratio. The experimental group received three micro-ostoperforations (MOPs) distal to maxillary canine, using the Lance pilot drill. The retraction of maxillary canine was performed with NiTi coil-spring (150g) in both experimental and control groups. The primary outcome was the evaluation of canine retraction rate, measured on study models from the baseline to 16 weeks of canine retraction. Secondary outcomes were the estimation of alkaline and acid phosphates activity in GCF at 0, 1, 2, 3, and 4 weeks. RESULTS: There was a statistically significant difference in the rate of canine retraction only after the first 4 weeks. Subsequently there was no statistically significant difference from the eighth to the sixteenth weeks between MOPs and control group. There was a statistically significant difference in alkaline and acid phosphates activity in GCF between MOPs and control groups during the initial 4 weeks of canine retraction. CONCLUSION: Micro-ostoperforation increased the rate of tooth movement only for the first 4 weeks; thereafter, no effect was observed on the rate of canine retraction during 8, 12 and 16 weeks. A marked increase in biomarker activity in the first month was observed.

RESUMO Introdução: As micro-osteoperfurações (MOPs) são uma técnica minimamente invasiva que tem sido utilizada para acelerar a movimentação dentária ortodôntica e reduzir o tempo de tratamento. No entanto, existem relatos conflitantes sobre o uso dessa técnica. Objetivo: Avaliar a eficácia das MOPs em acelerar a taxa do movimento de retração de caninos e na expressão de biomarcadores no fluido crevicular gengival (FCG). Métodos: Esse foi um ensaio clínico randomizado com desenho de estudo do tipo boca dividida. Trinta indivíduos adultos com idade acima de 18 anos (20,32 ± 1,96 anos) que necessitavam de tratamento ortodôntico fixo e extração de primeiros pré-molares superiores foram incluídos e aleatoriamente alocados para o grupo experimental ou grupo controle. A randomização foi realizada pelo método de randomização em bloco, com proporção de alocação de 1:1. O grupo experimental recebeu três MOPs distais ao canino superior, utilizando uma broca piloto em formato de lança. A retração do canino superior foi realizada com mola helicoidal de NiTi (150g) nos dois grupos, experimental e controle. O desfecho primário foi a avaliação da taxa de retração dos caninos, medida em modelos de estudo do início da retração até 16 semanas depois. O desfecho secundário foi a estimativa da atividade da fosfatase alcalina e ácida no FCG após 0, 1, 2, 3 e 4 semanas. Resultados: Houve uma diferença estatisticamente significativa na taxa de retração dos caninos somente após as quatro primeiras semanas. Após isso, não houve diferença estatisticamente significativa entre os grupos experimental e controle entre a oitava e a décima sexta semanas. Houve uma diferença estatisticamente significativa na atividade da fosfatase alcaline e ácida no FCG entre os grupos experimental e controle durante as quatro primeiras semanas de retração dos caninos. Conclusão: As micro-osteoperfurações aumentaram a taxa de movimentação dentária apenas nas primeiras quatro semanas; depois disso, nenhum efeito foi observado na taxa de retração dos caninos após 8, 12 e 16 semanas. Houve aumento considerável na atividade do biomarcador no primeiro mês.

Esthetic management of complicated crown fracture of three permanent maxillary teeth by grout technique -A case report.

Dental injury particularly anterior teeth trauma has severe effects on the social and mental prosperity of a patient hence requiring useful and esthetic repair at the most urgent. Customarily, fracture anterior teeth have been reestablished with composite tars; in any case, they have the essential disservice of shading bungle and variable wear. On the off chance that the tooth's fracture section is accessible and sound, reclamation of the tooth utilizing its own particular piece has likewise been recommended. Reattachment of tooth part ought to be considered and is a practical other option to customary methodologies as a result of effortlessness, unmatched characteristic style, and preservation of tooth structure. It can give great and dependable style in light of the fact that the tooth's unique anatomic shape, shading, and surface are kept up. Patient collaboration and comprehension of the restrictions of the treatment is of most extreme significance for the good result. This case report accentuation the inventive strategy of overseeing crown root break treated effectively utilizing tooth part reattachment.

Sequential Utilization of E-space for Correction of Moderate Crowding: A Case Report.

Leeway space and E-space plays a crucial role in the late transition phase from primary dentition to permanent dentition. Leeway space is normally 0.9 mm and 1.5 mm in upper and lower arch respectively. E-space is the difference in the mesiodistal width of deciduous second molar and permanent second premolar which is 2.3 in upper arch 2.5 mm in lower arch 1. E-space and leeway space are normally utilized by permanent first molars to establish class I molar relation in permanent dentition. We can also utilize this E-space during fixed orthodontic treatment for reliving of crowding in late mixed dentition. Thus, here in this article, we are presenting clinical technique along with case series of sequential utilization of E-space for correction of anterior crowding without extractions.

Assessment of the relationship between maxillary rotation and nasal morphology in males.

BACKGROUND: Nasal features are important in treatment planning for orthodontic treatment. AIMS AND OBJECTIVES: The purpose of the study was to assess the relationship between maxillary inclination and nasal morphology in males. MATERIALS AND METHODS: Forty-five samples were selected for the study between the age group of 18 and 30 years. Selected individuals were subjected to cephalometric radiography. These lateral cephalograms were traced and divided into three groups on the basis of the angle given by Schwarz for rotation of the maxilla. The nasal features of these groups were evaluated and compared using mean, standard deviation, Student's t-test and analysis of variance. RESULTS: The results suggest that there was statistically significant difference in nasal height, nasal bone length (NBL), nasal depth, nasolabial angle (NLA), nasal tip angle and upper lip inclination angle in different maxillary inclination group. CONCLUSION: The nasal height, NBL, NLA and nasal tip angle had a maximum value in retro inclination group.
