The aim of the present study was to evaluate the incidence of somatosensory abnormalities and neuropathic pain symptoms and its impact on oral health quality of life on patients rehabilitated with single immediate implant loading. 33 patients with single-tooth loss on the posterior region of maxilla or mandible were evaluated at 8 different times (baseline; 3 days; 7 days; 15 days; 1 month; 3 months; 6 months; and 1 year). DN4 and OHIP-14 questionnaires were applied for tracking neuropathic pain and oral health quality of life, respectively. Also, thermal QST and QualST were performed at the contralateral and ipsilateral region to the surgery, extra- and intraorally. Descriptive statistic was reported for DN4 results as the Repeated Measures ANOVA test on OHIP-14 data. The Two-Way Repeated Measures ANOVA test and post hoc Tukey test were used on QST values and Cochran Q test on QualST. DN4 data suggesting neuropathic pain were not seen after 1 month follow-up. At the operated side, overall CPT (extraoral: p=0.030), CDT and CPT (intraoral: p<0.001) decreased over time. In the contralateral region, maxilla CDT (extraoral: p=0.024; intraoral: p=0.031), WDT (extraoral: p=0.026; intraoral: p=0.047) and overall CPT (extraoral and intraoral: p<0.001) also decreased. QualST showed extraoral pinprick stimuli (p=0.032) and intraoral pinprick (p=0.000), cold (p=0.000) and touch (p=0.002) stimuli abnormalities over time. The OHIP-14 values showed a significant improvement (p<0.001). Although minor somatosensory abnormalities were found, those did not represent clinical relevant changes, confirming single-tooth immediate loading surgery as a low risk procedure and with a positive impact on the oral health-related quality of life.
