Optimum Ortho with Removable & Fixed Appliances
1 #39 Ortho-Tain, Inc. 1-800-541-6612 OPTIMUM ORTHODONTICS FOR THE 5 TO 12 YEAR-OLD BY COMBINING REMOVABLE AND FIXED APPLIANCES WITH THE USE OF THE NITE-GUIDE AND OCCLUS-O-GUIDE APPLIANCES INTRODUCTION: Early intervention of common orthodontic problems seen developing in the late deciduous dentition as the mandibular incisors begin to erupt is frequently made more efficient by a combination of appliances. For example, the Nite-Guide technique is an efficient means of preventing overbite, increasing arch development and correcting overjet. There often develops, however, a shortage of arch size for cases where, (a) the maxillary canines erupt in a mesial direction, (b) there is a bi-lateral constriction of the upper arch, (c) where the upper permanent molars are positioned too far mesially or have been rotated mesio-lingually; due to loss of arch length from deciduous molar loss or decay, (d) where there is insufficient arch development for the incoming (upper and/or lower) incisors, (e) where persistent thumb or finger sucking is preventing the full eruption of permanent incisors, and (f) incomplete eruption, rotation and torque corrections of the permanent teeth. These six examples of problems can be associated with the use of the Nite-Guide technique and can also occur in the mixed dentition when the Occlus-o-Guide would be used. These six problems are usually easily rectified by various forms of limited fixed appliance methods and associated appliances such as the quad-helix, cervical head-gear, and maxillary and/or mandibular bumpers, rapid palatal expanders, anti-thumb sucking appliances as well as various other removable appliances. -
Current Evidence on the Effect of Pre-Orthodontic Trainer in the Early Treatment of Malocclusion
IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) e-ISSN: 2279-0853, p-ISSN: 2279-0861.Volume 18, Issue 4 Ser. 17 (April. 2019), PP 22-28 www.iosrjournals.org Current Evidence on the Effect of Pre-orthodontic Trainer in the Early Treatment of Malocclusion Dr. Shreya C. Nagda1, Dr. Uma B. Dixit2 1Post-graduate student, Department of Pedodontics and Preventive Dentistry, DY Patil University – School of Dentistry, Navi Mumbai, India 2Professor and Head,Department of Pedodontics and Preventive Dentistry, DY Patil University – School of Dentistry, Navi Mumbai, India Corresponding Author: Dr. Shreya C. Nagda Abstract:Malocclusion poses a great burden worldwide. Persistent oral habits bring about alteration in the activity of orofacial muscles. Non-nutritive sucking habits are shown to cause anterior open bite and posterior crossbite. Abnormal tongue posture and tongue thrust swallow result in proclination of maxillary anterior teeth and openbite. Mouth breathing causes incompetence of lips, lowered position of tongue and clockwise rotation of the mandible. Early diagnosis and treatment of the orofacial myofunctional disorders render great benefits by minimizing related malocclusion and reducing possibility of relapse after orthodontic treatment. Myofunctional appliances or pre orthodontic trainers are new types of prefabricated removable functional appliances claimed to train the orofacial musculature; thereby correcting malocclusion. This review aimed to search literature for studies and case reports on effectiveness of pre-orthodontic trainers on early correction of developing malocclusion. Current literature renders sufficient evidence that these appliances are successful in treating Class II malocclusions especially those due to mandibular retrusion. Case reports on Class I malocclusion have reported alleviation of anterior crowding, alignment of incisors and correction of deep bite with pre-orthodontic trainers. -

Distalization of the Mandibular Dentition with Mini-Implants to Correct a Class III Malocclusion with a Midline Deviation
CASE REPORT Distalization of the mandibular dentition with mini-implants to correct a Class III malocclusion with a midline deviation Kyu-Rhim Chung,a Seong-Hun Kim,b HyeRan Choo,c Yoon-Ah Kook,d and Jason B. Copee Uijongbu and Seoul, Korea, Philadelphia, Pa, and Dallas, Tex This article describes the orthodontic treatment for a young woman, aged 23 years 5 months, with a Class III malocclusion and a deviated midline. Two orthodontic mini-implants (C-implants, CIMPLANT Company, Seoul, Korea) were placed in the interdental spaces between the mandibular second premolars and first mo- lars. The treatment plan consisted of distalizing the mandibular dentition asymmetrically and creating space for en-masse retraction of the mandibular anterior teeth. C-implants were placed to provide anchorage for Class I intra-arch elastics. The head design of the C-implant minimizes gingival irritation during orthodontic treatment. Sliding jigs were applied buccally for distalization of the mandibular posterior teeth. The active treatment period was 18 months. Normal overbite and overjet were obtained, and facial balance was improved. (Am J Orthod Dentofacial Orthop 2010;137:135-46) very orthodontic tooth movement is accompa- patients. Therefore, several authors have attempted to nied by a reaction. This can make it difficult to treat this type of malocclusion by distal tooth movement Ecorrect a malocclusion by using intraoral appli- alone. For example, animal studies and clinical investi- ances alone, especially when complete distal movement gations have used conventional implants as absolute of the mandibular dentition is planned in nonsurgical anchorage2-4 and miniplates for intrusion or distalization Class III malocclusion treatment. -
Molar Distalization-A Review
Molar Distalization - A Review Dr. Sumnima Sharma1 , Dr. Vijayta Yadav2, Dr. Neha Choudhary3 P G Student1,3, Reader2, Department of Orthodontics & Dentofacial Orthopedics, Career Post Graduate Institute of Dental Sciences & Hospital , Lucknow Abstract The most important step of gaining space in the dental arch in treatment planning can be achieved by different methods one of which is molar distalization. Various appliances have been introduced to distalize molars by using non extraction treatment. Headgear was the first appliance which was used for this purpose but this appliance need patient cooperation and was esthetically unpleasant. Thus there were various intra oral appliance which have been introduced. How to cite this Article: Sharma S, Yadav V, Choudhary N.Molar Distalization - A Review.

Intraoral Approaches for Maxillary Molar Distalization: Case Series Dentistry Section
DOI: 10.7860/JCDR/2017/25656.9922 Case Series Intraoral Approaches for Maxillary Molar Distalization: Case Series Dentistry Section DEVINDER PREET SINGH1, SHEFALI ARORA2, SUMIT KUMAR YADAV3, NEAL BHARAT KEDIA4 ABSTRACT Correction of Class II malocclusion by distalization of maxillary molars with intraoral appliances is a non-extraction treatment approach, which has been described as an alternative to Head Gear. From the past few years, the procedures have undergone rectification to achieve treatment objective more precisely. This has been made possible by a better understanding of bone physiology, tooth movement, biomechanics and newer biomaterials. Nowadays newer distalizing appliances, like the Jones Jig, Lokar distalizer and Carrière distalizer, have been developed which have compact designs and cause minimal discomfort to the patient. Refinement in these appliances is concentrated mainly on achieving bodily movement of the molar rather than simple tipping. These appliances are also operator friendly as these are easy to insert and remove. The present case series presents the efficacy of these appliances in Class II malocclusion patients with a mean age of 16 years (age range of 15-17 years) that reported with the chief complaint of irregular upper front teeth, since non-extraction approach in correcting Class II malocclusion is gaining a lot of attention.

Caruso et al. BMC Oral Health (2019) 19:182 https://doi.org/10.1186/s12903-019-0880-8 RESEARCHARTICLE Open Access Impact of molar teeth distalization with clear aligners on occlusal vertical dimension: a retrospective study Silvia Caruso1†, Alessandro Nota1,2*†, Shideh Ehsani2, Elena Maddalone2, Kenji Ojima3 and Simona Tecco2 Abstract Background: A common strategy in the non-extraction treatment of Class II molar relationship is maxillary molar distalization, which could increase lower face height and cause clockwise mandibular rotation. The aim of this retrospective study was to analyse the effects on vertical dentoskeletal dimension of young adults treated with sequential distalization with orthodontic aligners. Methods: Lateral cephalometric radiographs of 10 subjects (8 females 2 males; mean age 22.7 ± 5.3 years) treated with upper molars sequential distalization with orthodontic aligners (Invisalign, Align Technology, San Josè, California, USA) were analyzed. Results: No statistically significant difference was observed for the primary outcome SN-GoGn between T0 and T1 and it was recorded a mean variation of 0.1 ± 2.0 degrees. Statistically significant differences were found in the linear position of the upper molars (6-PP, 7-PP) the molar class relationship parameter (MR) and the upper incisive inclination (1^PP) with at least p < 0.01. Conclusions: Upper molar distalization with orthodontic aligners guarantee an excellent control of the vertical dimension representing an ideal solution for the treatment of hyperdivergent or openbite -

Parmar, Govt. medical college, Nahan Abstract Molar scissor-bite is a common finding in orthodontics and many times, it can be found as a sole malocclusion in a patient. Alignment of such buccally erupted molars is a challenging task. This article describes a modified use of conventional quad helix appliance to correct scissor bite in a growing child. Keywords: Scissor bite, malocclusion, quad helix, early treatment. Introduction techniques.[1,5] Scissors bite, also known as buccal crossbite is Cross elastics have a disadvantage of extrusion of the buccal occlusion of the maxillary teeth with the molars and also require patient compliance. Many palatal mandibular teeth and can be classified as complete cantilever arches are designed which are activated with or incomplete, unilateral or bilateral.[1] In the young e-chains. These are difficult to manage clinically and patient scissor bite may not be urgent, but it can hide a require frequent activations due to e-chain’s faster force problem with the temporomandibular joint (TMJ) that decay. Pulling the upper molar palatally with elastic can become manifested with growth.[2] This abnormality traction from a single palatal implant causes the crown may not resolve by itself and if left untreated would of the tooth to tilt lingually, burying its lingual cusps affect chewing and muscle function and may impair into the mucosa, posing problems in banding the molar normal growth and development of the mandible.
