Description
Occlusal analysis and adjustment identifies and corrects bite imbalances causing tooth wear, jaw pain, or headaches, with costs typically ranging from ¥300–¥1000; ChinaMedicalHub assists with hospital booking and interpreter support.
Main Uses
Primary purposes include diagnosing occlusal discrepancies contributing to temporomandibular disorders (TMD), evaluating functional stability before and after restorative or orthodontic treatment, identifying premature contacts or interferences causing pain or tooth mobility, guiding occlusal adjustments for prosthetic rehabilitation (e.g., crowns, bridges, implants, dentures), and managing bruxism-related wear or fracture risk. Applicable scenarios: pre-prosthetic assessment, post-orthodontic retention evaluation, TMD workup, unexplained tooth sensitivity/mobility, and recurrent restoration failure.
Normal Range
There is no universal numerical 'normal range' for occlusal analysis and occlusal adjustment (occlusion adjustment) as it is a qualitative, functional, and biomechanical clinical assessment—not a quantitative laboratory test. Key evaluated parameters include: intercuspal contact symmetry (ideally even, bilateral, simultaneous), occlusal contact timing (centric relation should coincide with maximum intercuspation within 0.1–0.3 mm tolerance), absence of premature contacts or interferences (<0.05 mm thickness foil detection), lateral and protrusive guidance angles (typically 20°–40° for canine guidance; 10°–25° for group function), and occlusal force distribution (measured via T-Scan or pressure-sensitive films: ideal load ratio <1.5:1 between left/right sides and <2:1 anterior/posterior). No standardized reference values exist across populations due to individual anatomical and functional variability.
Low Values - Possible Causes
1. Hypo-occlusion (excessive tooth wear or over-reduction during restorative procedures), 2. Open bite malocclusion (skeletal or dental origin), 3. Insufficient vertical dimension of occlusion (e.g., severe edentulism or long-term denture use), 4. Neuromuscular dysfunction (e.g., trigeminal motor weakness or Parkinson’s-related bradykinesia affecting jaw closure), 5. Iatrogenic errors in prosthodontic fabrication (e.g., under-occluded crowns or bridges).
High Values - Possible Causes
1. Hyper-occlusion (premature contact due to unadjusted restoration or crown), 2. Bruxism or clenching habits causing localized occlusal trauma and elevated contact forces, 3. Occlusal interferences from malpositioned teeth or orthodontic relapse, 4. Temporomandibular joint (TMJ) disc displacement leading to compensatory occlusal changes, 5. Inflammatory periapical pathology causing protective avoidance and apparent 'high' contact on contralateral side.
