Clinical trials

In everyday clinical practice, the proper management of the post-extraction socket is crucial in order to enable an optimal healing of the wound and a close post-surgical monitoring is critical to prevent possible complications. After an injury, the cellular reaction starts early, presenting significant changes as soon as 12 to 24 hours later. Favourable wound healing begins with the timely formation, organization, stabilization, and attachment of the blood clot. The stability of the clot is influenced by various factors including the host response, local anatomical characteristics, presence of bacteria and severity of surgical trauma. Delayed healing can lead to increased complications, patient discomfort, and potential procedure failures. In the light of these considerations, the proven effectiveness of piezoelectric devices to facilitate healing mechanisms is known in literature. Inverse piezoelectric effect, as used in current devices, creates mechanical shock waves that oscillate linearly at sonic and ultrasonic frequencies (from 30 to 30.000 Hz). In addition, mechanical micro-movements with a frequency between approximately 24 and 30 kHz create a cavitation effect in the irrigation solution, limiting intraoperative bleeding, thereby increasing the visibility and safety of the procedure. The purpose of the present study is to evaluate if the application of cavitation effect of post-extractive socket is capable of reducing healing time and Numeric Pain Rating Scale (NPRS) values.

The goal of this observational study is to monitor, within a cohort of patients requiring rehabilitation at two different sites in the premolar area, the primary and secondary stability of implants placed with different surface treatments: vacuum-plasma activation, ozonated oil and non-activated implants.
