Bone loss of edentulous alveolar ridges.

RRR is probably multifactorial process subject to a wide number of covariables. In any given patient, these convariables will be in a unique combination which will determine the rate of RRR for that patient at that time. If the variable change in any given patient, the rate of RRR may change. The dentist who wishes to help his edentulous patient should seek to be sensitive to all these variables, and to understand and treat that unique combination of factors which exists in that patient.
