Abstract
Background. Class III Angle malocclusion represents a major challenge in modern orthodontics due to its
multifactorial etiology, clinical variability, and increased risk of relapse during the growth period. Early
diagnosis and interceptive intervention are essential for guiding craniofacial development and reducing the
complexity of subsequent treatment. Among the objectives of orthodontic treatment are the correction of
anterior crossbite, elimination of functional dysfunctions, and creation of favorable conditions for harmonious
development of the maxilla and mandible, thus contributing to the balanced formation of the stomatognathic
system.
Objective of the study. To highlight the particularities of interceptive treatment of Class III Angle
malocclusion using temporary prosthetic restoration in mixed dentition, employing functionally guided partial
crowns.
Material and Methods. The study is based on a synthesis of the scientific literature and on clinical experience
gained in the interceptive treatment of children with Class III malocclusion. The method consists of the use
of acrylic overlay crowns that cover the occlusal surfaces, increase the vertical dimension of occlusion (VDO),
eliminate occlusal interferences, and facilitate the “occlusal jump By rotating the occlusal plane and
repositioning the mandible posteriorly and superiorly, favorable conditions are created for functional
reorganization of the temporomandibular joint (TMJ) and harmonious jaw development. The method was
applied to a 6-year-old patient in early mixed dentition diagnosed with mandibular prognathism and anterior
crossbite. Cephalometric investigations confirmed a tendency toward skeletal Class III malocclusion.
Treatment included professional cleaning, intraoral scanning, digital planning, and fabrication of functionally
guided partial crowns using specialized software.
Results. After treatment, improvement of the facial profile, harmonization of facial thirds, and achievement
of Class I molar and canine relationships with controlled overcorrection were observed. The method ensured
occlusal stability and superior functional and esthetic comfort compared to conventional interceptive methods.
Conclusions. Interceptive treatment guided by overlay crowns represents an effective and minimally invasive
alternative for early management of Class III malocclusion, promoting physiological adaptation of the
stomatognathic system and harmonious craniofacial growth guidance.
