Enhancing the Predictability of Clear Aligners
Enhancing Predictability of Clear Aligners Bowman DRASTIC PLASTIC: ENHANCING THE PREDICTABILITY OF CLEAR ALIGNERS S. Jay Bowman ABSTRACT Once limitations of clear aligner treatments were identified, conceptualizing techniques to improve the predictability in producing desired results was the next logical step. A variety of concepts, methods, and adjuncts have subsequently been introduced to enhance the efficiency and effectiveness of clear aligners. As a consequence, the scope of biomechanics and type of malocclusions that can be more predictably treated has increased. As one example, the inclusion of miniscrew temporary skeletal anchorage has permitted the addition of direct and indirect anchorage to support and control more predictable programmed tooth movements with aligners. After reviewing the reported shortcomings of plastic aligners, this chapter explores possibilities for improving predictability of aligner therapy. KEY WORDS: Clear Aligners, Miniscrews, Bootstrap Elastic, Attachments, Bonded Buttons INTRODUCTION It has been 20 years since the introduction of a commercialized clear aligner product to the orthodontic marketplace. Based on suggestion by Harold D. Kesling over 50 years earlier, Invisalign and later, increasingly numerous propriety alternatives have come to pass; including the exponential growth of so-called direct-to-consumer (DTC or DIY) offerings [1]. From the original questions of whether even “acceptable” results could be obtained from a sequence of aligners, these queries have now evolved into: Is an orthodontist even needed to be interjected between the manufacturer’s plastic and their “customers?” So, the idea of moving teeth with plastic was nothing new, but the use of software to attempt to predict desired tooth movement and the associated 3D representations of individual tooth position were innovative. -

Stability of Anterior Open Bite Treatment with Molar Intrusion Using Skeletal
González Espinosa et al. Progress in Orthodontics (2020) 21:35 https://doi.org/10.1186/s40510-020-00328-2 REVIEW Open Access Stability of anterior open bite treatment with molar intrusion using skeletal anchorage: a systematic review and meta- analysis Daybelis González Espinosa1,2, Paulo Eliezer de Oliveira Moreira1, Amanda Silva da Sousa1, Carlos Flores-Mir3 and David Normando1* Abstract Objectives: The aim of this systematic review and meta-analysis is to assess the degree of stability of anterior open bite (AOB) treatment performed through the molar intrusion supported with skeletal anchorage at least 1 year posttreatment. Methods: This study was registered in PROSPERO (CRD42016037513). A literature search was conducted to identify randomized (RCT) or non-randomized clinical trials based including those considering before and after design. Data sources were electronic databases including PubMed, Cochrane Library, Science Direct, Google Scholar, Scopus, Lilacs, OpenGrey, Web of Science, and ClinicalTrials.gov. The quality of evidence was assessed through the JBI tool and certainty of evidence was evaluated through the GRADE tool. Random effects meta-analysis was conducted when appropriate. Results: Six hundred twenty-four articles met the initial inclusion criteria. From these, only 6 remained. The mean posttreatment follow-up time was 2.5 years (SD = 1.04). The overbite showed a standardized mean relapse of − 1.23 mm (95% CI − 1.64, − 0.81, p < 0.0001). Maxillary and mandibular incisors presented a non-significant mean relapse, U1-PP − 0.04 mm (95% CI − 0.55, 0.48) and L1-MP − 0.10 mm (95% CI − 0.57, 0.37). Molar intrusion showed a relapse rate around 12% for the maxillary molars and a 27.2% for mandibular molars. -
TITLE PAGE Treatment Outcome with Orthodontic Aligners and Fixed
Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2020 Treatment outcome with orthodontic aligners and fixed appliances: a systematic review with meta-analyses Papageorgiou, Spyridon N ; Koletsi, Despina ; Iliadi, Anna ; Peltomaki, Timo ; Eliades, Theodore Abstract: Background: The use of orthodontic aligners to treat a variety of malocclusions has seen considerable increase in the last years, yet evidence about their efficacy and adverse effects relative to conventional fixed orthodontic appliances remains unclear. Objective: This systematic review assesses the efficacy of aligners and fixed appliances for comprehensive orthodontic treatment. Search methods: Eight databases were searched without limitations in April 2019. Selection criteria: Randomized or matched non-randomized studies. Data collection and analysis: Study selection, data extraction, and risk of bias assessment was done independently in triplicate. Random-effects meta-analyses of mean differences (MDs) or relative risks (RRs) with their 95% confidence intervals (CIs) were conducted, followed by sensitivity analyses, and the GRADE analysis of the evidence quality.Results: A total of 11 studies (4 randomized/7 non-randomized) were included comparing aligners with braces (887 patients; mean age 28.0 years; 33% male). Moderate quality evidence indicated that treatment with orthodontic aligners is associated with worse occlusal outcome with the American Board of Orthodontics Objective Grading System (3 studies; MD = 9.9; 95% CI = 3.6-16.2) and more patients with unacceptable results (3 studies; RR = 1.6; 95% CI = 1.2-2.0). No significant differences were seen for treatment duration. The main limitations of existing evidence pertained to risk of bias, inconsistency, and imprecision of included studies. -
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.
