Summary
Local factors like implant proximity to teeth pose risks to dental implant survival. However, evidence for other factors such as soft tissue thickness and keratinized tissue width is limited, requiring more research.
Area of Science:
- Dental Implantology
- Periodontology
- Biomaterials Science
Background:
- Dental implant therapy involves numerous local factors that may influence outcomes.
- Understanding these factors is crucial for optimizing implant success and longevity.
Purpose of the Study:
- To evaluate the impact of local risk factors on dental implant survival and success.
- To assess secondary outcomes including mucosal recession, bleeding on probing, and marginal bone loss.
Main Methods:
- A comprehensive literature review was performed.
- Inclusion criteria were applied to human clinical studies.
- 19 relevant articles were selected after screening 2,681 publications.
Main Results:
- Placing implants within 3 mm of adjacent teeth increases the risk of proximal bone loss.
- Insufficient data exists on implant placement in infected sites, though it may be feasible.
- Soft tissue thickness, keratinized tissue width, and bone density were not identified as significant risk factors for implant survival based on current data.
Conclusions:
- The multifactorial nature of implant therapy complicates the isolation of specific risk factors.
- Conclusions are constrained by a lack of high-quality clinical trials in this field.
