Smartee introduces the S8, S9 and S10 as solutions for mandibular repositioning to enhance your orthodontic treatments.
Achieving ideal orthodontic treatment results goes beyond just aligning teeth, especially in complex Class II and Class III cases. Mastering mandibular repositioning is key to achieving functional balance, occlusal harmony, and long-term skeletal stability. With the right knowledge and tools, you can elevate your clinical practice and deliver more precise, predictable outcomes.
Smartee Denti-Technology, in collaboration with Professor Gang Shen and leading research institutions, has developed a systematic approach to mandibular repositioning. This includes Prof Gang Shen’s Diagnostic Classification of Malocclusion, which provides a framework for categorising different clinical indications, analysing developmental mechanism, and offering comprehensive technical solutions and devices. To address varying mandibular repositioning needs, Smartee has introduced a range of innovative devices, with the S8, S9, and S10 serving as core solutions.

S8 mandibular advancement devices
The S8 appliances, including the S8-SGTB and S8-SGHB, offer orthodontists a highly adaptable and precise means to address diverse cases of mandibular retrusion, ensuring optimal treatment outcomes with minimal invasiveness.
- S8-SGTB: primarily used for the treatment of facial convexity malocclusion associated with physiological mandibular retrusion, including skeletal Class II cases characterised by deep overbite, large overjet and excessive curve of Spee, and a mandibular body exhibiting a flat and horizontally rectangular morphology
- S8-SGHB: designed to address facial convexity malocclusion associated with pathological mandibular retrusion with arthropathies, particularly skeletal-originated mandibular retrusion caused by condylar resorption. This type of malocclusion typically presents a triangular morphology of the mandibular body.
S9 mandibular repositioning device with bite plane
The S9 is a clear version of the maxillary bite plane, uniquely designed to handle complex orthodontic cases where forward mandibular positioning is contraindicated due to facial profile concerns. It works by vertically opening the occlusion of anterior and posterior teeth.
The S9 is particularly effective in cases such as:
- Class I molar relationships with deep overbite in patients with a straight profile
- Mandibular positioning-originated facial convexity malocclusions with mandibular retrusion and mandibular deviation associated with condylar resorption.
S10 mandibular repositioning device with occlusal splint
The S10 anatomical occlusal splint corrects the deviated mandible to its normal position. Its main indications include:
- Mandibular positioning-originated facial concavity
- Absolute mandibular positioning-originated deviation
- Pathological joint-originated mandibular deviation, including cases caused by condylar asymmetric hyperplasia or resorption.
Histological mechanism for mandibular repositioning
The clinical therapy of orthodontics is supported by two major histological mechanisms, which are periodontal and alveolar remodelling for dislocating orthodontic teeth, maxillary jawbone suture remodelling for reshaping the maxilla, and temporomandibular joint remodelling for displacing the mandible.
Mandibular repositioning, as an orthopaedic therapy, amplifies or reinitiates the biological pathway for bone formation in condylar cartilage. It stimulates condylar growth and reconstructs disc-condyle-fossa relationship to stabilise the advanced mandible at a new position, thereby re-establishing jaw relationships and ultimately correcting deep overbite, large overjet, and excessive curve of Spee. It can also correct the mandibular retrusion and deviation caused by pathological condylar resorption.
TMJ plays a vital role in the post therapeutic stabilisation mechanism of mandibular repositioning. By means of mandibular repositioning and occlusal reconstruction, the interlocking, restraining, mutually coordinated and balanced relationship between occlusions, joints, and jaw positions are restored, serving as the physiological basis for stabilising the new mandibular position; periodontal remodelling, as a result of TMJ reconstruction and occlusal contact caused by mandibular repositioning, serves as the histological basis for stabilising the new position of mandible.
