Abstract

Introduction: Post-extraction socket bone regeneration is becoming a cutting-edge theme in implantology nowadays. Bone regeneration uses the mixed between Plasma Rich in Growth Factors (PRGF) and biomate-rials as fillings materials in places where implants will be placed.

Aim of de study: The purpose of this study was to evaluate whether the use of Nd:YAG laser and PRGF enhance the post-extraction bone regeneration.

Description: The protocol used is the study was:

• Iodine is used in order to increase the therapetic effect of the laser.

• Nd:YAG laser was used with a low potency, pulse, optic fiber 20 μ of diameter and the following parame-ters:

• Slow and continuous movements were done during the time neccessary to eliminate all granulation tissues.

• Place PRGF and bone grafting. Membrame was placed.

• Waiting time for implantology: 4-6 months

Evolution: A review of 180 clinical cases in which tooth extraction were carried out using our protocol. In all clinical cases bone regeneration was successfully to carry a rehabilitation with implants.

Discussion: Researchers’ opinions differ concerning the effectiveness of laser in post-extraction socket for bone regeneration. Bibliography shows evidence that support the theory that the use of the laser may help bone healing, making it quicker. Other authors say that this type of procedure shall be used in patients whose bone regeneration is affected by a medical condition such cáncer or biphosphonates.
