SHANGHAI, July 8, 2026 /PRNewswire/ — Professor Gang Shen, Chief GS R&D Scientist
of Smartee Denti-Technology and Chief Orthodontist at Taikang Dental, together with
his orthodontic team, has published a new research article titled "**_Pathological
Mandibular Retrusion: Causality and Orthodontic Intervention"_** in Issue 2 of 2026
of the **Journal of Aligner Orthodontics (JAO).**

The publication marks the team’s third consecutive paper in JAO since 2025. Together
with the previously published "**_A New Classification System for Malocclusions 
with Facial Convexity_** and **_Working Mechanism" _**_and _**_"Clinical Management
of Mandibular Advancement Repositioning Technology in Treating Three-Depth Malocclusion_****
_in Adult Patients"_**, the latest study forms a research series covering malocclusion
classification, treatment mechanisms, and the pathogenesis and orthodontic management
of pathological mandibular retrusion.

**Advancing the Understanding of Pathological Mandibular Retrusion**

The newly published paper focuses on the **etiology, clinical characteristics, and
orthodontic management of pathological mandibular retrusion (MPaR)**. It describes
MPaR as a clinical condition associated with temporomandibular joint (TMJ) status,
mandibular morphology, and characteristic occlusal features. The study proposes 
a structured framework for patient assessment and discusses orthodontic intervention
approaches based on long-term clinical observations.

According to the authors, patients presenting with skeletal facial convexity and
a triangular mandibular morphology may show increased susceptibility to temporomandibular
disorders (TMD). The paper further discusses condylar resorption as a potential 
factor contributing to mandibular retrusion and outlines associated occlusal characteristics
that may support earlier identification and more comprehensive clinical evaluation.

**From Mechanisms to Orthodontic Intervention**

Based on long-term clinical experience and research, the paper further discusses
an orthodontic intervention approach centered on mandibular repositioning. The proposed
protocol, using the Smartee S8-SGHB clear aligner system, aims to guide the mandible
toward a more stable therapeutic position while supporting the reconstruction of
occlusal and temporomandibular joint relationships.

The authors also highlight the importance of comprehensive TMJ assessment and longitudinal
monitoring before, during, and after orthodontic treatment, particularly in patients
with skeletal facial convexity and triangular mandibular morphology.

The publication of this three-paper series reflects the team’s ongoing research 
efforts in mandibular repositioning and related clinical topics. Through continued
collaboration between Smartee Denti-Technology and Professor Gang Shen’s orthodontic
team, research findings are being explored for translation into digital orthodontic
technologies and clinical applications, supporting the continued development of 
clear aligner therapy based on clinical evidence.
