The diagnostic framework expands on conventional strategies by together with facial look, jaw place, and joint well being to information orthodontic remedy planning.
A analysis group led by Gang Shen, BDS, MDS, PhD, chief scientist of GS Know-how at Smartee Denti-Know-how, has printed a brand new diagnostic framework titled “A New Classification System for Malocclusions with Facial Convexity” within the 2026 Quantity 1 situation of the Journal of Aligner Orthodontics (JAO).
Increasing Conventional Diagnostics
Whereas the normal Angle classification system focuses totally on molar relationships, the brand new analysis integrates further parts into the diagnostic course of. These embrace facial look, mandibular place and morphology, depth of the curve of Spee, and temporomandibular joint (TMJ) well being.
The examine investigates the mechanisms behind distinct facial convexity subtypes and proposes particular remedy methods based mostly on scientific indications and biomechanical ideas.
Mandibular Morphology Evaluation
The analysis introduces mandibular morphology evaluation, which evaluates the general contour of the mandibular physique and the diploma of symphyseal concavity utilizing lateral cephalograms.
The paper notes that leveling the occlusal curve is a prerequisite for attaining the specified mandibular repositioning impact. It additionally advises that the need of tooth extraction needs to be evaluated based mostly on this refined diagnostic classification.
“This classification system bridges the hole between preliminary analysis, remedy planning, and long-term scientific outcomes,” says Shen, lead creator and chief scientist of GS Know-how at Smartee Denti-Know-how, in a launch. “By figuring out particular mandibular morphologies, practitioners could make extra knowledgeable choices between standard extraction therapies and mandibular development repositioning.”
Scientific Utility and Know-how
The classification system serves because the theoretical basis for Mandibular Development Repositioning Know-how (MART) and Smartee’s GS product line. This consists of the S8-SGTB, a specialised equipment designed for treating facial convexity.
Radiographic follow-up knowledge from the examine signifies that MART, when carried out by way of programs just like the S8-SGTB, can facilitate adaptive TMJ reworking. In response to the researchers, this gives a non-surgical various for attaining sustainable mandibular repositioning in grownup sufferers.
