Stability of protraction Facemask/Rapid Maxillary Expansion in skeletal class III malocclusion with maxillary deficiency: Rapid Review

Citra Elitasari Rigel PUTRI, Avi LAVIANA, Gita GAYATRI


this study aimed to evaluate the stability of PFM/RME outcomes in class III skeletal malocclusion
with maxillary deficiency performed during childhood. Electronic database search conducted from 2011-2020 with
criteria RCT, clinical trials, and cohort studies with a treatment group of class III skeletal malocclusion with
maxillary deficiency patients, using PFM/RME and a minimum of 2 years follow-up. The PFM/RME device has
been commonly used for maxillary protraction in cases of maxillary growth deficiency and is used during
childhood. The stability of the PFM/RME protocol results aims to maintain the best possible treatment results.
There were 439 articles from the preliminary search. Six articles were included in this study, two articles were RCT
types, and the other four were CCT types. Clinical evaluation and cephalometric are used to evaluate skeletal and
dentoalveolar changes. 68%-90% of participants maintained overjet until the follow-up period ended. PFM/RME
protocol reduced the need for orthognathic surgery by 3,5 times compared with a control group with no
treatment.PFM/RME treatment can effectively show in the short term from skeletal dan dentoalveolar changes.
There were relapses during the long-term follow-up period. Further evaluation and research are needed regarding
the long-term stability of PFM/RME outcomes.
