The Application of a CO2 Laser in Implant Site Development: A Case Report

Abstract

Introduction: Ridge preservation procedures have been utilized to minimize the alveolar ridge dimensional changes following tooth extraction. This case report describes a novel approach to ridge preservation with an application of a carbon dioxide laser (CO2 laser) to stabilize blood clot formation and stimulate wound healing.

Case presentation: A 76-year-old Caucasian male with history of type 2 diabetes was referred for extraction of #8 and placement of a dental implant to reconstruct the area. Extraction was performed in a minimal traumatic manner and a mineralized freeze-dried bone allograft was placed in the socket. A 10,600 nm wavelength CO2 laser was used in setting of 1.0 watts focused continuous wave energy to stabilize the blood clot over the extraction site. The laser was used until a char layer was formed. This char layer was a non-bleeding stable blood clot, and the end-point of laser application was set as “no blood flow from the clot are within 10 seconds.” No membranes or sutures were used. Eleven weeks after the extraction and ridge preservation, a 4.1x10mm dental implant was placed with >35N/cm of primary stability and Implant stability quotient (ISQ) value of 83. A provisional crown was delivered at the time of implant placement. Three months following implant placement, the final restoration was delivered. The soft and hard tissue healing were uneventful to achieve esthetic and functional outcomes.

Conclusion: Within limits of this case report, the application of CO2 laser for “Laser-Assisted Blood Clot Formation” may enhance the soft and hard tissue healing following extraction for ridge preservations.
