Study Notes
Avoiding Bad Implant Treatment Outcomes
- Understand personal limitations and the complexity of each case.
- Classify treatment difficulty and communicate risks and alternatives to patients.
- Develop a thorough treatment plan.
Factors Influencing Implant Treatment Outcomes
-
Patient Factors:
- Dental and medical risk factors, anatomical risks, and smoking habits.
-
Clinician Factors:
- Experience, skills, and clinical judgment.
-
Biomaterials:
- Quality documentation and material characteristics.
-
Treatment Approach:
- Comprehensive documentation and evaluation of risk based on SAC classification.
ITI SAC Classification
- Evaluates potential difficulty and risk levels of implant cases.
- Guides clinicians in case selection and planning.
- Three classifications:
- S: Straightforward
- A: Advanced
- C: Complex
Classification by Esthetic Risk
- Straightforward cases lack esthetic risks.
- Esthetic zones must be considered either advanced or complex due to higher challenge levels.
Complexity Determinants
- Complexity assessed based on procedural steps involved and areas needing successful outcomes.
- Predictability of outcomes plays a crucial role in determining complexity.
Complication Risks in Treatment
- Increased difficulty in managing potential surgical and restorative complications.
- Unacceptable outcomes may lead to short-term or long-term failures.
Loading Protocols
- Immediate Loading: Restoration in occlusion within 48 hours of implantation.
- Early Loading: Restoration contact with opposing dentition done between 48 hours and 3 months post-placement.
- Conventional Loading: Prosthesis attached after a healing period of 3-6 months.
- Delayed Loading: Prosthesis attached after the conventional healing period.
- Immediate Restoration: Restoration within 48 hours without occlusal engagement.
Modifying Factors for SAC Classification
- Considerations include general factors, esthetic factors, surgical challenges, and restorative factors.
General Risk Factors for Implant Therapy
- Medical Risks: Conditions affecting bone health or immune response.
- Periodontal Risks: Active or historical periodontal disease.
- Oral Hygiene: Patient compliance and hygiene practices.
- Occlusal Issues: Conditions like bruxism.
Esthetic Modifiers to Implant Treatment
- Factors influencing aesthetics: medical status, smoking, lip line, gingival biotype, tooth shape, infection, surrounding restorations, and anatomical considerations.
Impact of Smile Line on Esthetics
- Low Smile Line: Minimal esthetic risk, less visibility of peri-implant margin.
- Medium Smile Line: Moderate esthetic risk, potential visibility of mucosal margin.
- High Smile Line: High esthetic risk, significant exposure of peri-implant margin.
Tissue Biotypes and Esthetics
- Thick Biotype: Greater than 2 mm tissue thickness, less prone to trauma, and more stable.
- Thin Biotype: Less than 1.5 mm tissue thickness, prone to recession and trauma, requiring careful handling.
Tooth Shape and Esthetics
- Square Shape: Favorable aesthetics with stronger proximal contacts, reduced risk of bone loss.
- Triangular Shape: Higher risk for black triangles, less favorable for filling inter-proximal spaces.
Adjacent Bone Level and Esthetics
- Adjacent bone height affects the restoration of esthetics; bone loss complicates this effort.
Bone Requirements Around Implants
- Minimum of 1 mm of bone needed on palatal and facial aspects around implants.
Recommendations for Partial Wall Presence During Implant Placement
- Utilizing a staged treatment approach due to unpredictable outcomes associated with simultaneous bone augmentation.
Influence of Tooth Loss Reason on SAC Classification
- Lower risk for tooth loss due to caries or trauma; higher risk associated with periodontal disease or occlusal issues.
