Within the limits of the study, both treatment procedures resulted in significant reduction in REC at 12 months. No statistically significant differences were found between PCM+CAF and CTG+CAF with regard to any clinical parameter. The collagen matrix represents a possible alternative to CTG.
The present study showed that the combined orthodontic and periodontic therapy performed resulted in the realignment of extruded teeth with infrabony defects, obtaining a significant probing depth reduction, clinical attachment gain, and radiological bone fill.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
