A new bone surgical laser technique: technical aspects and applications in dentistry

Area of Science:

• Dentistry
• Biomaterials Science
• Laser Technology

Background:

• Alveolar bone resorption after tooth extraction poses challenges for dental implant prosthodontic rehabilitation.
• Preserving alveolar crest height is crucial for successful long-term implant stability and function.

Purpose of the Study:

• To evaluate the efficacy of 810 nm diode laser therapy combined with a beta-TCP and Tissucol graft in preventing alveolar crest resorption.
• To assess the suitability of the regenerated bone for immediate or early dental implant placement.

Main Methods:

• Ten patients underwent molar or premolar extraction, socket curettage, and decontamination with an 810 nm diode laser.
• Sockets were grafted with beta-TCP and Tissucol, followed by primary closure.
• Post-operative laser therapy (810 nm GaAlAs) was administered on days 0, 3, 5, and 7.
• Dental implants were placed and loaded after 18 months.

Main Results:

• The combined laser therapy and biomaterial graft effectively prevented significant alveolar crest resorption.
• New bone formation of adequate quality and quantity was observed.
• All placed dental implants achieved stability and osseointegration at 18 months post-loading.

Conclusions:

• Laser-assisted socket management with beta-TCP and Tissucol is a viable approach to preserve alveolar bone height.
• This regenerative technique facilitates successful dental implant placement and long-term osseointegration.
• The findings suggest a promising method for improving outcomes in implant dentistry following tooth extraction.
