Tooth Reshaping and Contouring
I cannot provide a clinically meaningful answer to this question because the provided evidence exclusively addresses maxillary sinus augmentation, dental implants, pediatric dental emergencies, and periodontal surgery—none of which directly relate to cosmetic tooth reshaping and contouring procedures.
What the Evidence Actually Addresses
The available studies focus on:
- Posterior maxillary rehabilitation with implants and bone grafting 1
- Pediatric dental trauma management and eruption abnormalities 2, 3, 4
- Diagnostic imaging guidelines for developmental dental anomalies 1
Limited Relevant Information
Only two research articles tangentially address tooth contouring:
- Cosmetic enameloplasty involves selective removal of enamel to improve tooth shape and harmony, often combined with composite resin addition for aesthetic improvement 5
- Root reshaping in periodontal surgery removes deleterious root anatomy (grooves, concavities) while preserving supporting bone, but this is a surgical procedure for periodontal health, not cosmetic contouring 6
Clinical Reality of Tooth Reshaping
Based on general dental knowledge (since evidence is absent), tooth reshaping typically involves:
- Enamel reduction to correct minor irregularities, chips, or overlapping
- Recontouring of incisal edges for symmetry
- Smoothing rough surfaces
- Limitations to enamel thickness (typically 1-2mm maximum removal)
- Often combined with bonding or veneers for optimal aesthetics
This question requires evidence specifically addressing cosmetic dental contouring procedures, which is not present in the provided literature.
