摘要: The extraction of teeth involves the elimination extremely sensitive periodontal mechanoreceptors, which play an important role in oral sensory perception. Objectives: aim this study was to evaluate recovery interocclusal perception for micro-thickness individuals with different types implant-supported prostheses. Materials and Methods: Wearers complete dentures (CDs) comprised negative control group (group A, n=17). experimental consisted wearers prostheses supported by osseointegrated implants (Group B, n=29), subsequently divided into 4 subgroups: B1 (n=5) – implant overdentures (ISO) occluding CD; B2 (n=6) fixed (ISFP) B3 (n=8) maxillary mandibular ISFP, B4 (n=10) ISFP natural dentition (ND). Individuals ND represented positive C, n=24). Aluminum foils measuring 10 μm, 24 μm, 30 μm, 50 μm, 80 μm, 104 μm thickness were placed within premolar area, adding up 120 tests each individual. Results: mean tactile thresholds groups B1, B2, B3, B4, C 92 μm, 27 μm, 14 μm, respectively. [Correction added after publication online 18 April 2008: preceding sentence 10 μm corrected 10 μm.] Kruskal-Wallis test revealed significant difference among (P<0.05). Dunn that A statistically from C. Conclusion: Progressive osseoperception as a function combination could be observed. Moreover, ISO and/or combinations may similarly maximize osseoperception.
