As a core tool in modern dental diagnosis and treatment, the performance of oral endoscopes directly depends on the technical level of their core component—the camera module. The OCH2B30 camera module launched by OmniVision Group in 2024 (with ultra-small size of 2.6mm×2.6mm, 2-megapixel resolution, and compatibility with 3D intraoral scanners) not only fills the technical gap in ultra-small, high-resolution modules but also reflects the core direction of the industry's future development. Combined with the 11.1% compound annual growth rate (CAGR) of the global dental intraoral scanner market (2022-2030) and the upgrading of clinical needs, the future oral endoscope camera modules will present five clear development trends, each supported by current technological breakthroughs, with both feasibility and rigor.
This trend will be further deepened in the future: On one hand, packaging technology will upgrade to "chip-level integration." Through wafer stacking technologies such as PureCel®Plus-S, it will integrate light sources (e.g., micro LEDs) and signal processing units while maintaining an ultra-small size, reducing reliance on external components. On the other hand, the module diameter may further decrease to less than 2mm to adapt to scanning of more delicate oral areas (e.g., interdental spaces, gingival sulcus). This integration not only reduces device size (e.g., portable intraoral scanners) but also lowers the calibration difficulty of multi-camera collaboration, improving scanning efficiency.
The core requirement for imaging in dental diagnosis and treatment is "discernible details and capture of dynamics"—it must clearly display micro-features such as early dental caries texture and periodontal pocket depth, while addressing dynamic scenarios like patient swallowing and changes in mouth opening. The OmniVision OCH2B30 has achieved a frame rate of 60 fps at 1500×1500 resolution and 120 fps at 720p resolution. It also uses a CMOS sensor with 1.12μm pixel size, which maintains high signal-to-noise ratio even in low-light environments. These parameters already meet basic clinical needs.
Future upgrades of imaging performance will be more "clinically targeted": First, the pixel size may be optimized to less than 1.0μm. Combined with back-illuminated sensor technology, it will further improve the ability to capture details in low-light environments (e.g., shadowed areas deep in the oral cavity). Second, the frame rate will be increased to over 120 fps for 3D scanning scenarios to avoid image blurring caused by slight patient movements, ensuring the accuracy of 3D model reconstruction. Third, image processing algorithms will be deeply integrated with dental scenarios—for example, built-in modules for "tooth texture enhancement" and "gum color restoration" will reduce the cost of post-processing software adjustments and directly output images that meet clinical diagnostic standards.
Oral endoscope camera modules directly contact oral mucosa and undergo frequent disinfection and sterilization processes, making medical compliance a core threshold. The OmniVision OCH2B30 has passed ISO 13485 certification and EMC/EMI testing, with biocompatibility and waterproof performance. It also requires no calibration before delivery, significantly simplifying the FDA approval process.
Future compliance systems will extend toward "full-lifecycle reliability": First, sterilization compatibility will upgrade from "single-use sterilization" to "repeated sterilization for over 100 times" to meet the needs of high-frequency use. Second, biocompatibility will improve from "non-toxic" to "low allergenicity" to reduce mucosal irritation. Finally, "long-term power-on stability testing" (e.g., 1000 hours of continuous operation without failure) will be added to avoid interruptions in diagnosis and treatment. This deepening not only reduces medical risks but also helps enterprises enter global markets quickly.
3D intraoral scanning has replaced traditional dental impressions, and camera modules are the core guarantee of 3D scanning accuracy. The ultra-small size and high frame rate of the OmniVision OCH2B30 support synchronous data collection by multiple cameras, providing high-density data for 3D modeling.
Future synergy will upgrade toward "data closed-loop": On one hand, modules will integrate "real-time 3D point cloud output" to shorten post-processing time. On the other hand, built-in lightweight AI chips will enable functions such as "real-time dental caries identification," upgrading modules from "imaging tools" to "diagnostic auxiliary nodes." In addition, integration of Wi-Fi 6 and Bluetooth 5.3 will support real-time data exchange with diagnostic software and patient management systems, forming a complete data chain of "scanning-diagnosis-treatment planning."
The global dental intraoral scanner market is growing rapidly (from USD 570 million in 2022 to USD 1.33 billion in 2030), driven by the demand for cosmetic dentistry, the high incidence of oral diseases due to aging, and the equipment upgrading needs of primary medical institutions. The mass production capacity of the OmniVision OCH2B30 provides a "high-performance + mass-producible" solution for the market.
Future market-driven development will be reflected in two aspects: First, application scenarios will expand from "high-end clinics" to "primary institutions/family care," with the launch of "entry-level modules" (retaining core performance while simplifying non-essential functions to reduce costs). Second, customized modules will be developed for segmented scenarios—such as "wide-field modules" for orthodontics and "macro HD modules" for periodontal diseases—to achieve precise matching. This not only expands market scale but also promotes the popularization of oral medical equipment.
