Abstract
BackgroundArch 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.MethodsA 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.ResultsA 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.ConclusionsThis 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.
Highlights
Arch length preservation strategies utilize leeway space or E-space in the mixed dentition to resolve mild to moderate mandibular incisor crowding
This review considered the studies pertaining to arch length preservation utilizing lingual holding arch and lip bumper appliance as an interceptive procedure
Following full-text assessments, 7 articles were excluded: 6 articles were narrative or systematic reviews related to the use of similar appliances but with different outcome measurements, and 1 article was a conference abstract on the topic
Summary
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. Loss of mandibular arch length is an inevitable event during the transitional period, and it was estimated to be about 1.8 mm per side of the arch [1] This phenomenon raised a reasonable question that if simple arch length preservation during the transition period could provide adequate space to manage crowding in the mixed dentition without any active intervention [2]. Clinical studies could not demonstrate long-term lower incisor positional stability through ALPS when compared to mixed dentition expansion protocols or extraction of premolars [11]
