Introduction:

After tooth extraction, bone resorption phenomena occur that can affect the volume of hard and soft tissues. The aim of the present study was to show the results of treatment with mineralized bovine bone and collagen membrane of the post-extraction socket.

Clinical case:

A 45-year-old male patient with no relevant medical history came to the clinic for implant treatment due to the loss of the first right premolar. The patient was recommended a treatment plan consisting of extraction of the premolar followed by placement of an implant which, after a healing period, will be rehabilitated with a screw-retained crown. On the day of surgery, the extraction was performed. Subsequently, the socket was filled for alveolar preservation with a Bio-Oss® mineralized bovine bone xenograft (Geistlich, Wolhusen, Switzerland) and the wound was covered with a Mucograft® dermal collagen matrix (Geistlich, Wolhusen, Switzerland). After a 3-month healing period, the implant placement surgery was performed. The corresponding milling was performed and an IPX® implant (Galimplant, Sarria, Spain) with an internal connection and treated surface (sandblasted and etched) of 3.5 mm in diameter by 12 mm in length was inserted. Eight weeks after surgery, the implant was functionally loaded by placing a provisional crown. A definitive zirconium crown was then placed. The clinical follow-up time was 24 months, with no complications.

Conclusions:

The results of this clinical case demonstrate that dental implants can be inserted in areas regenerated with mineralized bovine bone covered with a collagen membrane for alveolar preservation.
