In case of the insufficient horizontal bone loss, a regular diameter implant is not possible without lateral bone augmentation. In this situation, narrow diameter implants (NDIs) could be the alternative to lateral bone augmentation procedures. However, complication generally expected with the NDI is implant fracture. Recently, the survival rate and success rate of NDI in the posterior region are similar to that of standard-diameter implants (SDIs). These 3 case reports demonstrate the incorporation of NDI to replace missing mandibular posterior teeth. So far, the follow-up examination period was maintained and no unusual complications were presented for more than four years. Long term follow-up clinical data are needed to confirm the excellent clinical performance of these implants.

A severely vertical resorbed ridge is a significant challenge in implant dentistry. To solve this problem, several augmentation techniques, such as guided bone regeneration (GBR), onlay bone grafts, distraction osteogenesis, and ridge splitting techniques, have been proposed and used for several years. Among these methods, vertical ridge augmentation using guided bone regeneration aims to build space and guide osteoblasts to this space to promote osteogenesis. The aim of guided bone regeneration is to maintain and stabilize the space and block the proliferation of adjacent soft tissue. In our hospital, we encountered a case of a woman in her forties with an atrophied mandible, who underwent implant surgery in the right mandible. Titanium reinforced Gore-Tex (TRG) was used to augment the mandible and titanium mesh was used in the left mandible. Favorable results were obtained. This report compares the two methods and reviews the relevant literature.
