The essential conditions for a successful osseointegration of dental implants are bone support and the bone-implant contact area. The aim of this study was to evaluate an innovative treatment in sheep periimplantitis, carried out in three stages: preparation of the implant bed, fixation of the implants and induction of periimplantitis. In phase I was verified the process of osteogenesis following the premolars extraction. Ten sheep were prepared by putting them on a diet before surgery and by giving them antibiotics. Under inhalatory anesthesia, a total of 8 premolars/animal were extracted by dislocating each one, followed by rotational movements in the perpendicular axis and straight traction to the outside. A hemostatic sponge was inserted into the tooth alveoli and the gum was sutured. After extraction, the sheep received anti-inflammatory and antibiotic treatment. During the monitoring period, the local and general clinical conditions were monitored, and bone regeneration was assessed by Computer Tomography. Clinically, the evolution was favorable, with no signs of discomfort, with gum scarring in 7 days and weight gain of 24-41%. Imagistic, a degree of bone atrophy within physiological limits could be observed, and the density of the neoformation bone tissue showed an optimal regeneration. Through the approached technique we provided a favorable environment for performing the next stages of the study, the osteogenesis process being validated both clinically and paraclinical. We also propose this method for flocks of sheep with dental diseases.
