Abstract

The extraction of the tooth inevitably leads to the remodeling of the alveolar ridge and the loss of the soft and hard tissues. Objective. Aim — to understand the efficacy of the alveolar ridge soft tissue preservation by using the root fragment of the extracted tooth as a coverage of the alveola. Materials and methods. Vestibular soft tissue thickness in the two groups of patients was measured before the tooth extraction and after the six months of the final restoration. Soft tissue under the root fragment biopsies were analyzed for the histo-morphometrical analysis after the 3 months of healing after the placement of the fragment. Results. In the control group of patients (20 subjects) the vestibular soft tissue thickness before the extraction of the tooth was 1.44 mm. After the extraction no socket preservation technique was used and socket healed under the blood clot. In the test group of patients (20 subjects) the vestibular soft tissue thickness before the extraction was 1.52 mm. After the extraction the root fragment socket preservation technique was used. After the three months of healing dental implants were placed in both groups of patients. Soft tissue thickness was measured again after the six months of the function of the final restoration. The vestibular soft tissue thickness represented 0.89 mm in the control group and 1.5 mm in the test group. The histo-morphometrical analysis generally showed that the soft tissue under the root fragment was a regular immature soft tissue with some proliferating cell elements and it could not be classified as a pathological tissue. Conclusion. It was concluded that the root fragment socket preservation technique is advantageous in order to preserve the volume of the vestibular soft tissue of the alveolar ridge in comparison with a classic socket healing under the blood clot. The root fragment socket preservation technique is effective in order to preserve the volume of the vestibular soft tissue which is important and advantageous for the further dental implant treatment.
