Dental implants in patients undergoing chemotherapy showed no significant difference in failure rates. More research is needed to confirm effects on infection and bone loss due to limited data.
Area of Science:
- Oral and Maxillofacial Surgery
- Oncology
- Biomaterials Science
Background:
- Chemotherapy can impact oral health and healing.
- Dental implants are a common rehabilitation option.
- Understanding chemotherapy's effect on implant success is crucial.
Purpose of the Study:
- To compare implant failure rates in patients undergoing chemotherapy versus those not.
- To investigate the impact of chemotherapy on postoperative infection and marginal bone loss around dental implants.
Main Methods:
- Systematic literature search in PubMed/MEDLINE, Web of Science, and Cochrane Oral Health Group Trials Register.
- Inclusion of human clinical studies, both randomized and non-randomized.
- Analysis of nine selected publications.
Main Results:
- No statistically significant difference in implant failure rates was found between patients with or without chemotherapy (Risk Ratio 1.02, P=0.95).
- Insufficient data precluded meta-analyses for postoperative infection and marginal bone loss.
Conclusions:
- Current evidence is insufficient to definitively conclude whether chemotherapy affects dental implant failure rates.
- Limited study specificity, small case numbers, and lack of control groups in existing literature hinder reliable conclusions.
- Further high-quality research is required to assess the impact of chemotherapy on implant outcomes, including infection and bone loss.
