Book excerpt: In a split-mouth design, 6 implants were placed in edentulous mandibular ridges of 10 mongrel dogs after preparation of 6 cylindrical mid- crestal defects, 5 mm in depth and 10 mm in diameter. An implant site was then prepared in the center of each defect to a depth of 5 mm beyond the apical extent of the defect. One mandibular quadrant received three commercially pure titanium screw implants (3.75 x 10 mm), while the contralateral side received three titanium double plasma sprayed hydroxyapatite-coated root-form implants (3.3 x 10 mm). Consequently, the coronal 5 mm of each implant was surrounded by a circumferential surgically created defect approximately 3 mm wide and 5 mm deep. The three dental implants in each quadrant received either canine demineralized freeze-dried bone (DFDBA) and an expanded polytetrafluoroethylene membrane (e- PTFE), membrane alone, or no treatment which served as the control. Standardized radiographs were taken at one week and 4 months post-implant placement. Computer-Assisted Densitometric Image Analysis (CADIA) was performed for each of the implants. After 4 months of healing, v block sections of the mandibles were harvested for light microscopy and histomorphometric analysis.
