Title Improvement Seen in Socket Preservation And Bone Resorption In Post Extraction Patients Treated With Bovine Bone Mineral And Porcine Collagen
Clinical Question Is bone resorption and socket preservation improved in post-extraction patients treated with bovine bone mineral and porcine collagen compared to extraction alone in patients wanting implants?
Clinical Bottom Line The use of bovine bone mineral and porcine collagen membrane decreases bone resorption compared to extraction alone.

#1) 22577648Cardaropoli/201241 Post Extraction Patients Randomized Controlled Trial
Key resultsThere was less reduction in ridge width in the SP group (1.04 ± 1.08 mm vs 4.48 ± 0.65 mm, P < .001) and height (0.46 ± 0.46 mm vs 1.54 ± 0.33 mm, P < .001). Histologically, there was bone formation and maturation without inflammation. No significant difference in the mineralized and non-mineralized fractions was noted between the SP and control group.

Comments on
The Evidence
This was a randomized controlled trial that included 41 patients who had one or more mandibular or maxillary molar or premolar extracted. The edentulous sites were randomly assigned to the experimental group (SP) or control group (EXT). The sockets were filled with bovine bone material and porcine collagen while the control group underwent extraction alone. The pocket probing depth, clinical attachment level, changes in residual ridge and histology were compared at baseline and after 4 months. All of patients completed the study and an adequate follow up was provided in order to compare residual ridge height, histology, PPD, and CAL.
Applicability Patients wanting successful implants post extraction
