THE AIM OF THESTUDY: To develop a method to contain atrophy of the alveolar bone and surrounding soft tissues in the area of many cortical teeth in the first 3 months after removal for subsequent installation of a dental implant.
MATERIALS AND METHODS: A description of a method for containing atrophy of the alveolar bone and surrounding soft tissues after removal of the first molar of the mandible 3 months after tooth extraction is presented. The method consists in closing the mouth of the well with a horizontally oriented fragment of the root of the removed tooth with a preserved section of the ligamentous apparatus. An X-ray assessment of bone restoration in the lumen of the well was carried out according to the Hounsfield coefficient and an assessment of the condition of soft tissues in the area of surgery 3 months after removal. For histological assessment of bone maturity, bone was taken from the implantation area 14 weeks after tooth extraction.
RESULTS: The technique allowed to preserve the quality of soft tissues close to the original; on three-dimensional X-ray images in the lumen of the well, bone restoration sufficient for the installation of a dental implant is diagnosed, the zonal value of the Hounsfield coefficient is more than 300 units; histologically, a well-developed network of coarse-fibrous trabeculae is determined with the beginning of reconstruction into lamellar bone, regeneration of the alveolar process occurs by intramembranous ossification.
CONCLUSION: The proposed technique contributes to the preservation of the qualities of the marginal gum in the healing zone after tooth extraction and the formation of sufficient bone maturity in the lumen of the well.
