“…7), which indicated bone resorption of varying degree in the crestal area of alveolar bone. This result agreed with studies of Ramfjord and Costich (1968) and Wood et al (1972), showed bone resorption of varying degrees occurs in the crestal area of the alveolar bone with flap implant surgery. 14,15 These results indicated that flapless surgery might be more effective than flap surgery, which agreed with the results of previous studies.…”

Osseointegration has been used as an index for prediction of long-term success of implant. Osseointegration has been routinely evaluated by measuring bone contact ratio on histology based on two-dimensional (2D) sections or images. However, these both methodologies have been less informative analysis of results and have several disadvantages. The aim of this study is to introduce new methodology for evaluation of a degree of osseointegration between bone and implant based on micro computed tomography (µ-CT) images. Specimen was scanned at a voxel resolution of 35 ㎛ by µ-CT. Three-dimensional (3D) models of bone and implant were reconstructed respectively. Bone contact area (BCA) and bone contact area ratio (BCAR) were measured and calculated. Here, osseointegrated BCA between bone and implant surfaces was determined by computing areas of all bone regions existed within 35 ㎛ distance from implant surface. Osseointegration of flapless implant surgery was evaluated by new methodology, compared with that of flap implant surgery. BCA and BCAR in flapless implant surgery was significantly bigger than that in flap implant surgery (p<0.05), suggesting that flapless implant surgery was more effective than flap implant surgery consistent with previous studies. In the conclusion, new methodology for evaluation osseointegration between bone and implant based on µ-CT images was likely to be reliable, useful and more informative analysis of results.

“…[4][5][6][7] It was also suggested that if a thick connective tissue covering did not remain over the bone, it should be protected by a mature epithelialized surface. 8 Hiatt et al 8 suggested that the loss of radicular bone could be minimized by reapposition of a mucoperiosteal flap over the exposed bone.…”

“…As previously demonstrated, the thickness of the remaining connective tissue coverage overlying the marginal radicular bone after reflection of the split thickness flap was probably inadequate from the standpoint of affording protection. [4][5][6][7][8] The graft probably served as a protective dressing and its own underlying connective tissue probably determined the type of epithe lial development. 17, 18 This resulted in the significant differences in the amounts of attached gingiva for the grafted sites compared to the split flap procedures.…”

Apically positioned split thickness flaps were performed at two selected sites in each of 10 patients. Equivalent amounts of periosteum were left exposed to standardize the method. In five patients the preoperative dentogingival margins consisted of gingiva, whereas in the five others a margin of alveolar mucosa was present. In all patients the pre-existing margin was sutured apically to periosteum, after reflection of the split thickness flap. At one surgical site in each patient a free soft tissue autograft, donated from the palate, was sutured to the periosteum left exposed coronal to the apically positioned flap margin. The second surgical site was left not covered by any biological dressing. Measurements from three fixed reference points on a stable acrylic device were recorded preoperatively and at 2, 4, 6, 8 and 12 weeks postoperatively. The graft and split thickness flap procedures were then biometrically compared by application of the Null Hypothesis and t test for the difference of the means to determine any significant differences. It was concluded that the presence of a preoperative dentogingival margin of gingiva suggested that either the free graft or split flap procedure would eliminate pockets extending beyond the mucogingival junction, and would establish adequate zones of attached gingiva without deformity at the dentogingival junction. However, the presence of a preoperative margin of alveolar mucosa suggested the use of the free soft tissue autograft to attain the above. The thickness of connective tissue afforded by a preoperative margin of gingiva was assumed to be the responsible factor for the above conclusions.
