Is There a Better Biomaterial for Dental Implants than Titanium?-A Review and Meta-Study Analysis

Area of Science:

• Biomaterials Science
• Dental Implantology
• Periodontology

Background:

• Peri-implantitis is a growing concern in dental implantology.
• Understanding the role of implant materials and surface modifications is crucial for long-term implant success.
• The peri-implant soft-tissue seal is vital for preventing peri-implantitis.

Purpose of the Study:

• To review preclinical evidence on dental implant and abutment materials from the last decade.
• To examine how different materials and surface modifications affect peri-implantitis.
• To compare titanium versus zirconia implants regarding clinical and radiographic outcomes.

Main Methods:

• Systematic review and meta-analysis of over 30 studies (RCTs, CCTs, prospective CS).
• Studies included had a minimum six-month follow-up period.
• Evaluated outcomes included bone changes, probing depth, plaque levels, and mucosal inflammation.

Main Results:

• No clear evidence indicated titanium superiority over other implant materials.
• Clinical data showed no significant difference in peri-implant bone stability between different materials.
• Meta-analysis revealed a statistically significant advantage for zirconia implants over titanium in promoting favorable alveolar bone response.

Conclusions:

• The choice of dental implant material may influence alveolar bone response.
• Further research is needed to fully elucidate the impact of surface modifications on the peri-implant soft-tissue seal and peri-implant health.
• Zirconia implants demonstrate a potential advantage in achieving favorable bone integration compared to titanium.
