Study Notes

Goals and Maintenance of Tissue Integration

Protect and maintain tissue integration through good oral hygiene and periodic recalls reinforcing regimen.
Successful implant maintenance aims to prevent peri-implantitis and retain tissue integration.
Marginal bone loss should be less than 0.1mm with no mobility.

Clinical Parameters and Signs of Implantitis

Clinical parameters include occlusion, proper torque on screws, bleeding, radiographic assessments, and implant system.
Signs of implantitis mirror abscess conditions, showcasing mobility, bleeding, and radiolucency.

Criteria for Successful Implant

Successful implants exhibit no peri-implantitis, marginal bone loss of 1.0-1.5mm in the first year, and less than 1mm annually thereafter.
Success rates depend on factors like bone quality, loading dynamics, implant placement location, and case selection.

Maintenance and Oral Hygiene Aids

Recommended maintenance includes home-care regimens, periodic recalls, and regular ultrasonic scaling.
Unrecommended practices for oral hygiene aids include hand scaling or specific chemicals like chlorhexidine not in line with clinical best practices.

Implant Stability and Radiographic Assessment

Implant stability indicates fixture health, while radiographic assessments are crucial for monitoring bone loss and implant success.
Rapid bone loss can occur due to occlusal trauma, incorrect implant sizing, or fixture fractures.

Dental Implant Prosthodontics

Implant prosthodontics involve similar procedures as natural teeth, but require meticulous occlusal adjustments and impression techniques.
New ideas in implant prosthodontics emphasize abutment selections and fitting techniques.

Impression Techniques

Two primary methods for taking implant impressions: open tray and closed tray techniques.
The selection of an impression method depends on factors like the dental area involved and the type of restoration, with fixture level used when vertical space is adequate.

Factors Affecting Implant Selection

Important factors for choosing an implant abutment include soft tissue levels, marginal bone level, type and diameter of implant, and mesio-distal dimension.
Apical bone quality impacts implant success; D1 to D5 bone densities range from high cortical density to loose trabecular structures.

Common Problems and Errors

Common issues during implant procedures include angulation errors and interference from surrounding bone structures.
For patients with limited mouth opening, issues like incorrect drilling angles and potential perforations can occur.

Contraindications and Considerations

Absolute contraindications for dental implants include severe renal disorders and myocardial infarction.
Relative contraindications cover active periodontal disease and significant smoking history.

Bone Density Impact on Implantology

Denser bone promotes better implant stability; however, conditions like osteoporosis in elderly patients can complicate outcomes.
The influence of bone density on success rate emphasizes that higher quality bone leads to better clinical outcomes.

Radiographic Advantages and Surgical Considerations

Panorama radiography aids in true anatomical imaging and bone height assessment, useful for treatment planning.
Surgical interventions for varying bone densities require specific drilling methods and careful planning to prevent complications.

General Principles

Ensure appropriate mesio-distal spacing between implants and natural teeth to maintain oral health.
Always consider patient's overall condition, including diabetes and other underlying health issues, when planning implant procedures.
