The presented feasibility case series aims to introduce an original titanium frame (TF) design, customized for each defect, as a modification of well-known principles and materials for GBR, for an enhanced and more predictable horizontal and vertical bone augmentation. Three patients with significant horizontal defects were treated with pre-trimmed TFs to create needed space, a 50%-50% mixture of autograft and bovine xenograft was placed, and then covered with collagen membrane. After 8 months of healing, the sites were reopened, the titanium screws were removed with the frame. An average of 8.0 ± 1.0mm horizontal and 3.0 ± 0.0mm vertical bone gain was achieved at the time of re-entry and implant placement surgery. Bone core biopsy was obtained during the implant placement. Histomorphometric analysis revealed that 42.8% of the sample was new vital bone, 18.8% was residual bone graft particles, and 38.4% was bone marrow like structures. After 3-4 months from implant placement, the implants were restored with provisional crowns and then finalized with zirconia screw-retained crowns.

The quality of studies was evaluated using the upgraded Jadad scale. Included studies were assessed for percent root coverage (PRC), clinical attachment level (CAL), keratinized tissue (KT), probing depth (PD), recession width (RW) and recession depth (RD). Weighted mean difference (WMD) was used as the statistics for measurement data and the effect sizes were expressed as 95% confidence intervals (CI). Totally 24 RCTs were eligible for the final analysis. The patients accepting ADM had a higher gain in CAL (WMD: 0.250, 95%CI: 0.030-0.470, P=0.026) but a smaller gain in KT width (WMD: -0.440, 95%CI: -0.629--0.252, P<0.001) than those receiving CTG.

Carbonate apatite (CO3Ap) granules (Cytrans Granules, GC) are chemically synthetic bone graft material that are similar to autologous bone mineral and more biocompatible than allografts and xenografts. The aim of this report is to evaluate the efficacy of CO3Ap granules in implant treatments using CO3Ap granules in combination with autogenous bone or CO3Ap granules separately. This report will show the clinical findings as well as radiographic and histological assessments in three cases of immediate implant placement, lateral GBR and vertical GBR. These results demonstrated, although it was a short-term report, that in histological findings CO3Ap granules were efficiently resorbed and replaced bone in clinical use. Furthermore, the clinical findings showed that CO3Ap granules contributed to maintaining their morphology tissue around the implant.
