The invention relates to a dental kit used for accelerating the recovery of the tissues affected by the insertion of an implant, and, implicitly, the osteointegration thereof, and also for treating diseases in the oral-maxillofacial area, such as periodontosis. According to the invention, the dental kit comprises two external mouth guards (A and B), the first of which has three work-points, and the second one has two work-points, an external mouth guard (F) with multiple work-points, a material (12) consisting of a polymer with high polarity and an apparatus (D) generating an electromagnetic field which generates, inside the mouth guards (A or B or F), a uniform field with an induction ranging between 0.7..Ø9 mT, with a variation ranging between 5...10%, in the area subjected to the electromagnetic field, on a distance of 1 cm around the same point, and on a volume as high as possible in the areas where the tooth root or the implant is to be positioned, produced by a current of 200 mA, with a frequency ranging between 7...8 Hz, preferably 7.69 Hz, the field lines being perpendicular on the target-tissue.
