Summary
Soft tissue dimensions are crucial for immediate implant success in the anterior maxilla. Incorporating these measurements into radial root position (RRP) classification enhances treatment predictability.
Area of Science:
- Dentistry
- Oral Implantology
- Radiology
Background:
- Immediate implant placement in the maxillary anterior region requires precise planning.
- Radial root position (RRP) classification is used to categorize tooth positions.
- Soft tissue and bone dimensions influence implant success.
Purpose of the Study:
- To investigate the relationship between soft tissue dimensions and RRP classification.
- To improve the accuracy of immediate implant placement planning in the anterior maxilla.
Main Methods:
- Analysis of 420 maxillary anterior teeth using cone-beam computed tomography (CBCT).
- Classification of teeth based on RRP (Classes I-V).
- Measurement of soft tissue thickness, supracrestal soft tissue height, crestal bone thickness, and keratinized tissue width. Gingival phenotype was also assessed.
Main Results:
- Class II RRP was most common (45%), followed by Class I (31.7%).
- Gingival phenotype and soft tissue dimensions showed significant differences across RRP classes (p < 0.05).
- RRP types IA and IIA were associated with thick soft and hard tissues.
Conclusions:
- Soft tissue dimensions are significantly related to RRP classification.
- Integrating soft tissue evaluation with RRP classification can enhance the predictability of immediate implant placement outcomes in the anterior maxilla.
