“…Regarding the use of direct application of forces on the MIs for the correction of molars on the sagittal plane , cases of uprighting all three mandibular molars were found, which were initially either mesially tilted or impacted. In order to treat these cases, several options regarding the insertion sites of the MIs were used: (a) in the retromolar area [ 2 – 5 , 12 , 15 , 23 , 25 ] (Figs. 2 and 3 ), (b) vertically in the alveolar ridge of a mesial edentulous molar site [ 2 , 26 ] (Fig 4 ), or (c) mesial to the mandibular molar and between the roots of the adjacent teeth [ 4 , 15 , 27 ] (Fig 5 ).…”

Mandibular molar uprighting using orthodontic miniscrew implants: a systematic review

2018

View full text Add to dashboard Cite

The purpose of this systematic review was to identify studies and present the use of miniscrew implants (MIs) as an alternative treatment to mandibular molar uprighting. An electronic search and handsearching were conducted by two independent reviewers to identify relevant articles, published up to January 27, 2017. In order to methodologically assess the eligible studies, a pilot checklist consisting of 22 items was also implemented. After exclusion of all the irrelevant papers, only 17 studies were included, presenting 27 cases of mandibular molar uprighting in all planes using both direct and indirect force traction by MIs. Regarding the quality evaluation, the mean score of the included studies was 13.2, indicating a rather poor methodology implemented in the majority of the included cases. Due to many advantages, MIs provide a unique treatment alternative and constitute a reliable solution for treating tipped or impacted molars. Regarding the force application, a direct method is simpler, as it requires one MI and a single bracket or button, minimizing the patient’s discomfort and also reducing chair time compared to more complex indirect anchorage. It also eliminates the possibility of unwanted movement of the anchorage unit, which can occur even with indirect anchorage as a result of technical errors. However, direct anchorage has limitations in cases of lingually tipped or rotated molars because a single force may be insufficient to upright the tooth.

“…Their attachment to the bone is mechanical with no intent to establish any form of osseointegration [ 21 , 22 ]. Therefore, after the treatment, when they are no longer needed, they can be removed through a simple procedure, with negligible risks for the patient [ 23 ].…”

“…The power chain can be adjusted every three weeks, to compensate for the force loss due to decay. However, Sivolella, et al suggested an elastic change every two weeks which seems an interesting road of investigation [33]. It can be explained with a slightly quicker correction time of approximately 2-4 months.…”

Introduction: Impaction of the lower second molars is quite rare ranging from 0 to 2.3% of the population and represents 0.03 to 0.04% of the overall dental impactions. This article aims to present and illustrate the simple orthodontic management approaches of the impaction of the lower second molars in synergy with Regional Acceleratory Phenomenon along with an overview of the main therapeutic options, their indications, and drawbacks. Materials and methods:An unrestricted database search was conducted via PubMed, Ovid Medline and Google Scholar performed until January 2022. Results:The main reason for the impaction or semi-impaction of the second lower molars is the lack of space in the posterior segment which may be necessary to evaluate the benefit/risk ratio at the beginning of impaction to perform the appropriate therapeutic option. Following a brief of the management along with the surgical and orthodontic protocol procedures, a new simplified orthodontic technique is presented combined with miniscrews. Discussion:The simplified protocol proposed in this article is simple to perform orthodontically, quick, and effective to upright second mandibular impacted molar. A rapid outcome is obtained by maximizing the Rapid Acceleratory Phenomenon created by removal of the wisdom tooth, surgical exposure of the lower second molar, and the thin interseptal bone between the lower second molar and wisdom tooth. However, an experienced clinician is required for the MIs placement. Conclusion:The contemporary evolution towards orthodontic treatments with a non-extraction protocol and with the benefit of the miniimplants will increase the therapeutic approaches along with the probabilities of easier molar uprighting in the impaction cases.

“…That indicates that the mechanics used in the treatment of this bimaxillary protrusion case had no unwanted effect on the vertical dimensions. Jacobs et al [ 28 ] reported that space closure following first molar extraction using anterior and premolar teeth as an anchorage has a side effect of posterior displacement for the soft tissue, which was accompanied by unpleasant profile changes. Furthermore, previous studies reported a midline shift as another side effect of first molar extraction on one side.…”

Atypical extraction in class I malocclusion: A case report

The treatment of Angle Class I malocclusion by atypical extraction is rather challenging. The extraction of four first premolars often manages it. However, in cases of compromised and non-restorable teeth, the extraction decision may be altered, making the anchorage and the treatment mechanics more challenging. This article reports the clinical case of a 16-year-old patient from Sudan who presented with a chief complaint “My teeth are crooked and sticking out.” He had Angle Class I malocclusion with a bimaxillary dentoalveolar protrusion. He had severe crowding in both arches and localized marginal gingivitis related to an ectopically erupted upper right canine (UR3) and lower right first premolar (LR4). The patient had a provisional restoration in the lower right first molar (LR6). Extraction of three first premolars and one first molar was the alternative of choice for this treatment, which restored function, providing improved periodontal health, achieved the desired facial esthetics, and allowed finishing with a stable and balanced occlusion. Management of angle class I malocclusion with atypical extraction patterns should be performed with careful mechanics and anchorage planning to obtain good results.
