Comparison of implant side and contralateral side molar regions

Comparison of occlusal contact area in the molar region

The occlusal contact area in the molar region on the implant and contralateral sides increased with clenching strength and, at clenching intensity of 60 % MVC or above, was less on the implant side molar region (Fig. 3). ANOVA results (Table 4) showed no significant differences in occlusal contact area between the implant side molar region and the contralateral side molar region with BiteEye (P = 0.092). Multiple comparison tests showed no significant differences in the occlusal contact area between the molar region on the implant side and the molar region on the contralateral side at any clenching intensity with either BiteEye or Occluzer (P > 0.05).

Comparison of occlusal load on the molar region

Occlusal load on the implant side molar region and the contralateral side molar region increased with clenching strength and, at clenching intensity of 80 % MVC and above, was less on the implant side molar region (Fig. 3). At 100 % MVC, the occlusal force on the implant side molar region was 212.7 ± 57.6 N and on the contralateral side molar region was 274.4 ± 111.5 N. ANOVA results (Table 5) showed no significant differences in occlusal load between the implant side molar region and the contralateral side molar region (P = 0.278). Multiple comparison test showed no significant differences in occlusal load between the molar region on the implant side and the molar region on the contralateral side at any clenching intensity (P > 0.05).

Comparison of occlusal load on the molar region excluding the first molar

Occlusal load on the implant side molar region and the contralateral side molar region excluding the first molar increased with clenching strength (Fig. 4). At 100 % MVC, the occlusal force on the implant side molar region was 165.0 ± 45.8 N and on the contralateral side molar region was 193.3 ± 85.8 N. ANOVA results (Table 7) showed no significant differences in occlusal load between the implant side molar region and the contralateral side molar region (P = 0.990). Multiple comparison test showed no significant differences in occlusal load between the molar region excluding the first molar on the implant side and the molar region on the contralateral side at any clenching intensity (P > 0.05).
