A reproducible surgical method for the production of reduced alveolar ridge in dogs using guided tissue regeneration principles is described. 3 defects resembling a reduced ridge were formed on both sides of the mandible in 4 dogs. In each of the dogs. a polytetrafluoroethylene membrane was placed on 4 defects. while 2 defects were covered by gingival flaps only. Half of the defects were allowed to heal for 6 weeks and half for 12 weeks. Bucco‐lingual width measurements revealed healing up to the membrane. In the uncovered defects, the bony wall width increased during the 12‐week healing period. Histological examination showed close adaptation between bone and membrane in well‐sealed defects. In cases of incomplete sealing, connective tissue had penetrated into the defect, resulting in unpredictable bone healing. The use of guided tissue regeneration techniques is suggested as a valuable tool in 1 creating experimentally reduced ridges.
