Tiivistelmä
Objective: The aim of this study was to analyze which occlusal traits can be corrected with prefabricated eruption guidance appliances (EGAs) in mixed dentitions.
Materials and methods: Articles written in English and published between January 1990 and March 2023 were searched from Cochrane Library, Clinicaltrials.gov, EMBASE, International Clinical Trials Registry Platform, LILAC, PubMed and Scopus. The inclusion criteria were formed according to the Patient; Intervention; Comparison; Outcomes; and Study design schema (PICOS). The risk of bias was evaluated using RoB 2 and ROBINS-I tools (PROSPERO CRD42023441197).
Results: The eligibility criteria were met by seven articles that included a total of 277 patients and 219 controls. One of the studies was a randomized controlled trial, one a retrospective study, and three were prospective treatment studies. In addition, two follow-up studies analyzed cephalometric data of already included studies. Four different prefabricated appliances were used: Education Fonctionnelle, LM-ActivatorTM, Nite-Guide® and Occlus-o-Guide®. Treatment protocols varied from passive nighttime use only to various combinations of active daytime use and passive nighttime use. Treatment periods varied from 10 months to 3.3 years. The main findings were reductions in overjet and overbite. Other findings included improvement in deep bite and better tooth-to-tooth contacts between incisors. Even though most of the changes were dental, significant increases in the length of the mandible were reported in two studies. Three studies were included in the meta-analyses. In these analyses, the changes in overjet, overbite, SNB and ANB were found statistically significant.
Conclusion: EGAs comprise a group of functional appliances suitable for reduction of excessive overjet and overbite. With good compliance they have an impact on mandibular growth. The treatment period should preferably exceed one year.
