Transverse Maxillary Deficiency is a recurrent orthodontic problem with multifactorial etiology. Posterior crossbite, narrow nasal cavity, and alar base are usually associated with maxillary deficiency and may lead to a higher frequency of mouth breathing and respiratory problems. The approach to maxillary atresia is based on the cause of the jaw's discrepancy, the patient's bone growth potential, and the magnitude of the correction. It usually involves a maxillary expansion procedure. We aim to present a new minimally invasive surgical technique associated with MARPE to treat maxillary transverse deficiency in adult patients. Parameters such as operative time, treatment-related pain, appliance type (bone-borne or tooth-bone-borne expanders), and dental and skeletal transverse maxillary effects will be discussed. The MISMARPE technique yields good skeletal outcomes with minimal trauma under local anesthesia in an ambulatory regimen. The presented technique can be an effective and lower-morbidity alternative to SARPE in mature adult patients.
Learning Objectives:
After this session, attendees will be able to:
Define the indications of the MISMARPE technique that uses the MARPE concepts associated with a Minimally Invasive Surgically procedure to correct transversal skeletal deficiency in mature skeletal individuals.
Evaluate the dental and skeletal effects of MISMARPE when compared to RPE, MARPE, and SARPE.
Recognize the advantages and disadvantages of the MISMARPE technique.
