Since Branemark introduced a new dental treatment, titanium implant, a dental implant could be a predictable treatment option if there is sufficient bone quantity and quality. Unfavourable conditions of the alveolar bone due to periodontitis, extraction, or trauma provoke a decrease in the alveolar ridge due to bone atrophy. Such bone atrophy could cause a change in the arch form and size in vertical, transverse, and sagittal planes, which may cause incorrect dental implant placement functionally and aesthetically.
