Results: Short implants in maxillary and mandibular rehabilitations
Implant length and diameter distribution are shown in Table 1. Table 2 summarizes implant positions and prosthetic characteristics. Mean residual bone height was 6.21 ± 1.05 mm in the upper jaw and 10.73 ± 1.63 mm in the mandible, and it was significantly different between the 2 jaws (P < .05). No surgical or postsurgical complications were reported.

Overall, cumulative implant survival and success rates were both 100%, and there were no prosthetic or clinical complication. Prosthesis success rate was also 100%.
One year after loading, a mean peri-implant bone loss of 0.71 ± 0.23 mm was recorded; there was no significant difference between mesial and distal measurements (P = .79). Maxillary implants had a mean bone loss of 0.69 ± 0.24 mm (Figures 1 and 2). Mandibular implants had a mean bone loss of 0.73 ± 0.23 mm (Figures 3 and 4). The difference between the 2 jaws was not statistically significant (P = .59).
All single implants were 8.5-mm long; shorter implants were splinted together or splinted with longer implants (10 mm or 11.5 mm, which were excluded from this study). After 1 year, bone loss around single implants and splinted ones was not significantly different (P = .67). Mean bone loss was 0.73 ± 0.23 mm for single implants and 0.70 ± 0.23 mm for splinted implants. No effect of implant abutment characteristics and dimension of platform switching could be evaluated by comparing the 8.5-mm implants with shorter implants in terms of peri-implant bone loss.
The effect on bone resorption of characteristics of the opposing teeth and prosthesis was negligible. Most of the included implants had natural teeth opposing (n = 36); the rest were occluded with teeth-supported prosthesis (n = 6). implant-supported prosthesis (n = 6), or composite restorations or removable prostheses (n = 5). Neither definitive prosthesis material influenced bone loss rate.
