For the lateral window technique, meta-regression analysis suggested a positive association between the initial alveolar bone height and implant survival rates. No relationship was found between the initial alveolar bone height and implant survival rate for the osteotome technique due to a lack of data below 4 mm of initial bone height.

The neutral part of the acetone extract from the bark of Pinus taiwanensis Hayata has been Investigated and found to consist of alkanes (C14‐C33), longifolene, aliphatic esters (C42, C44, C49), aliphatic alcohols (C24, C26), 3β‐21α‐dimethoxyserrat‐14‐enc, 3β‐methoxyserrat‐14‐en‐21‐one, β‐sitosterol, 3β‐methoxyserrat‐14‐en‐21ã‐ol and 3β‐hydroxyserrat‐14‐en‐21‐one.

Local delivery of osteogenic molecules has been investigated as an alternative to the use of autografts for managing large alveolar defects. Bone morphogenetic protein (BMP)-2 is among the most potent and frequently studied bioactive molecules.BMPs belong to the transforming growth factor (TGF)β superfamily, discovered by Urist in 1965(Urist, 1965. Urist identified an interfibrillar protein complex in demineralized bone that can induce ectopic bone formation (Urist & Strates, 1971). Isolation of the first BMP occurred only in the late 1980s (Wozney et al., 1988). Other BMPs were subsequently purified, characterized and cloned (Celeste
