excessive alveolar bone resorption is commonly found when teeth are extracted. this is a problem in anterior part of mouth because it will result in an unaesthetic pontic on a narrow hollowed out alveolar ridge. yet, another problem is gingival recession and root exposure in adjacent teeth which represent a therapeutic problem to the clinician. use of acellular dermal matrix graft is an appropr...

the biological mechanisms of tooth movement are based on the response of periodontal tissues to mechanical forces. the final result of these responses is remodeling of the extracellular matrix. tissue reactions may vary depending upon the type, magnitude and duration of the applied forces. the purpose of the present study was to analyze the effects of centrifugal force on the transcription of c...
