Clinical Study

The Use of Narrow Diameter Implants in the Molar Area

Table 1

The different parameters evaluated in our case series. Patient gender (F, female; M, male ), NDI position in the arch, bone management, type of prosthesis (fixed partial denture = FPD or single crown (SC)), loading protocol, type of edentulism (F = free end saddle, B = bounded saddle), splinted to wider diameter implant, nature of opposing arch, presence of a cantilever, follow-up period, and median probing depth.
