Description
Computer-assisted implant surgery uses 3D planning and real-time navigation for precise dental or orthopedic implant placement, often needed for complex cases or compromised bone; costs range ¥2,000–¥5,000, with ChinaMedicalHub coordinating hospital booking and interpreter support.
Main Uses
Dental implant navigation surgery is primarily used for precise, minimally invasive placement of dental implants in complex anatomical scenarios—such as severely atrophic jaws, proximity to vital structures (inferior alveolar nerve, maxillary sinus, nasal floor), immediate loading protocols, full-arch rehabilitation (All-on-4/6), and revision surgeries. It enhances accuracy, reduces intraoperative complications, improves prosthetic outcomes, and enables predictable treatment in compromised cases.
Normal Range
Dental implant navigation surgery is not a laboratory test with numerical values or reference ranges; it is a computer-assisted surgical procedure. Therefore, there is no 'normal range' of quantitative indicators (e.g., no lab values like mmol/L or ng/mL). Instead, success metrics include implant primary stability (measured as Insertion Torque Value: 20–50 N·cm; Resonance Frequency Analysis [RFA] ISQ value: 60–80), angular deviation (<3° from planned position), and depth deviation (<1 mm from planned depth). These are intraoperative/performance parameters—not patient biomarkers.
Low Values - Possible Causes
Low insertion torque (<20 N·cm) or low RFA ISQ (<60) may result from: 1) Low bone mineral density (e.g., osteoporosis or advanced alveolar atrophy); 2) Insufficient bone volume/quality (Type IV bone, severe resorption); 3) Over-preparation of osteotomy site (excessive drilling); 4) Use of undersized implants or improper surgical technique; 5) Early-stage healing or micromotion compromising stability.
High Values - Possible Causes
Excessively high insertion torque (>50–60 N·cm) or abnormally elevated RFA ISQ (>85) may indicate: 1) Dense cortical bone (e.g., Type I bone) causing excessive compression; 2) Under-preparation of osteotomy (narrow drill diameter relative to implant); 3) Implant thread design mismatch or aggressive insertion protocol; 4) Measurement artifact (e.g., sensor misalignment during RFA); 5) Post-surgical bone compaction or early osseointegration in highly favorable conditions.
