“…In such cases, an option would be lower arch expansion with a lip bumper. This appliance produces buccal inclination of the incisors and distal inclination of the permanent first molars, which increases perimeter and arch length 18 . An increase in the arch width was also reported.…”

Background The beneficial effect of the extraction of primary canines in the resolution of incisor irregularity and its side effects are controversial. Aim To systematically review the effects of the extraction of primary canines in incisor irregularity and dental arch morphology. Design Controlled non‐randomized (non‐RCT) and randomized clinical trials (RCT) evaluating children treated with extraction of primary canines compared with those without intervention. Results A total of 984 articles were found, of which two RCTs and one non‐RCT met the inclusion criteria. Both had a low RoB. A high level of evidence was observed through GRADE. A meta‐analysis showed the extraction of primary canines produced a significant decrease in incisor irregularity (95% CI: −3.56, −2.09 mm). This decrease, however, was associated with a reduction of arch length (95% CI: −1.58, −0.94 mm), intermolar width (95% CI: −0.61, −0.22 mm), and overjet (95% CI: −075, −018). A mild overbite increase was found (95% CI: 0.10, 0.76 mm). Conclusion A high level of evidence showed that the extraction of primary canines improved incisor irregularity in the mixed dentition. Side effects included reduced arch length and intermolar width. A slight reduction in overjet and a mild increase in overbite were also observed. When they are not part of the treatment goal, these occlusal changes can be prevented by installing a lingual arch.

“…This narrative review reported M2 impaction in 7–12% of the treated group and 1.4% in the untreated group. The second was a systematic review that evaluated the effects of lip bumper therapy on the mandibular dental arch of children and adolescents as the primary outcome and M2 eruption disturbances as the secondary outcome [ 28 ]. A number of other studies reported first molar distalization or arch length changes with lip bumpers when compared with untreated controls [ 29 – 33 ].…”

Background Arch length preservation strategies utilize leeway space or E-space in the mixed dentition to resolve mild to moderate mandibular incisor crowding. The purpose of this systematic review of the literature was to analyze the effects of arch length preservation strategies in on mandibular second permanent molar eruption. Methods A search for relevant articles published from inception until May 2020 was performed using PubMed/Medline, Cochrane databases, Clinicaltrials.gov, Google scholar and journal databases. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were adopted for the conduct of the systematic review. Using RevMan 5.3 software, the most pertinent data were extracted and pooled for quantitative analysis with 95% confidence intervals. Heterogeneity was analyzed by using Cochran Q test and I squared statistics. Results A total of 5 studies involving 855 mixed dentition patients with arch length preservation therapy were included in the qualitative analysis. Pooled estimate of the data from two studies revealed 3.14 times higher odds of developing mandibular second molar eruption difficulty due to arch length preservation strategies using lingual holding arch (95% CI; OR 1.10–8.92). There was no heterogeneity found in the analysis. The certainty levels were graded as very low. Conclusions This systematic review demonstrates that arch length preservation strategies pose a risk for development of mandibular second molar eruption disturbances, but the evidence was of very low quality. Registration number: CRD42019116643.

“…Arch perimeter management in the mixed dentition is a strategy often used to resolve space deficiencies in the mandibular arch. [1][2][3] The literature generally reported that this therapy was effective in relieving crowding in the anterior region of the mandibular arch, mainly through the preservation of the leeway space. [2][3][4] However, although the early preservation of space in the anterior area is usually considered a priority, less attention is given to what happens in the posterior region of the arch.…”

Objectives To investigate the association between the management of mandibular arch perimeter during development of the dentition and its effects on second permanent molar (M2) eruption. Materials and Methods Seven electronic databases were searched without restrictions up to June 2020. Assessment was performed using the Risk Of Bias In Non-randomized Studies of Interventions (ROBINS-I) tool for non-randomized clinical trials (non-RCT). Odds ratio (OR) with 95% confidence intervals was calculated from random-effects meta-analyses. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool was used to assess the certainty of the evidence. Results Five non-RCTs, with serious to moderate risk of bias, were included. A low certainty of evidence indicated that individuals undergoing mandibular arch perimeter management by controlling the position of the first molar had a high prevalence of M2 eruption difficulties. The odds of eruption disorders was 7.5 times higher (OR: 7.57, [3.72, 15.41], P < .001) in treated individuals. Subgroup analysis revealed that appliances that increased the arch perimeter lead to a greater chance of eruption disorders compared to appliances that only maintained the perimeter. The predictive factors for the M2 eruption difficulty were its previous mesioangulation in relation to the first molar (>24°) and the treatment time (>2 years). Conclusions Mandibular arch perimeter management during development of the dentition leads to an increase in the occurrence of M2 eruption difficulties. The identification of possible risk factors as well as the choice of the appropriate appliance type and the monitoring of these individuals seems to be essential to avoid undesirable effects with this therapy.
