Background:
Dental implant success depends on optimal osseointegration and soft tissue integration. Titanium surfaces experience biological aging over time, reducing their bioactivity. Photofunctionalization using ultraviolet (UV) light has been proposed to restore titanium surface properties and enhance clinical outcomes.
Materials And Methods:
A split-mouth study was conducted with 20 implants placed in 10 patients. Group I (n = 10) received non-photofunctionalized immediate implants, while Group II (n = 10) received photofunctionalized immediate implants. Soft tissue healing was assessed using intraoral scanning at days 0, 3, 6, and 15. Crestal bone levels were evaluated using radiovisiography at baseline, 2-, 4-, and 6-month postloading.
Results:
Photofunctionalized implants demonstrated significantly superior soft tissue healing (79.734% vs. 61.612% at day 15, P = 0.001). Additionally, photofunctionalized implants showed crestal bone gain (0.513 mm at 6 months), whereas non-photofunctionalized implants exhibited bone loss (-0.506 mm at 6 months), with statistically significant differences (P = 0.001).
Conclusion:
Photofunctionalization enhances soft tissue healing and promotes crestal bone gain, potentially improving long-term implant success rates.
