Objectives: The objective was to assess the accuracy of orthognathic surgical planning using three-dimensional virtual planning compared with conventional two-dimensional planning. Material and Methods: MEDLINE (PubMed), Embase and Cochrane Library search combined with hand-search of relevant journals was conducted to identify randomized controlled trials (RCTs) published in English through August 2nd, 2022. Primary outcomes included postsurgical accuracy of hard and soft tissue. Secondary outcomes included treatment planning time, intraoperative time, intraoperative blood loss, complications, financial expenses, and patient-reported outcome measures (PROMs). Quality and risk-of-bias assessment were evaluated by Cochrane risk of bias tool and GRADE system. Results: Seven RCTs characterised by low, high, and unclear risk of bias fulfilled inclusion criteria. Included studies disclosed conflicting results regarding accuracy of hard and soft tissue as well as treatment planning time. The intraoperative time was shortened, and financial expenses were increased with three-dimensional virtual surgical planning (TVSP), while no planning-related complications were revealed. Comparable improvement in PROMs were reported with TVSP and two-dimensional planning. Conclusions: Future orthognathic surgical planning will indisputable be performed by three-dimensional virtual planning. The financial expenses, treatment planning time, and intraoperative time will therefore probably decrease due to further development of three-dimensional virtual planning techniques. The hard and soft tissue accuracy between planned position and achieved surgical outcome seems to be improved by three-dimensional virtual planning compared with two-dimensional planning, although results are inconsistent. Further development of three-dimensional virtual planning involving cutting guides and patient-specific osteosynthesis plates are therefore needed to improve the accuracy of orthognathic surgical planning.

Purpose: To carry out a comparative evaluation of the intra- and postoperative complications, and bone healing, following bilateral sagittal split osteotomy (BSSO) with or without concomitant removal of third molars.Material and methods: A retrospective analysis was performed of two cohorts subjected to BSSO with the intraoperative removal of third molars (test group) versus the removal of third molars at least 6 months prior to BSSO (control group), comprising at least 1 year of clinical and radiographic follow-up. Partially or completely erupted third molars were extracted immediately before completing the osteotomy, whereas impacted third molars were removed after the osteotomy had been performed. Hardware reinforcement was performed in bimaxillary cases where concomitant molar extraction impeded placement of the retromolar bicortical screw of the hybrid technique.Results: A total of 80 surgical sites were included (40 in each group). Concomitant extraction of the molar represented a mean increase in surgery time of 3.7 min (p < 0.001). No additional complications occurred in the test group (p = 0.476). The gain in bone density was preserved in both groups (p = 0.002), and the increase was of the same magnitude in both (p = 0.342), despite the fact that the immediate and final postoperative bone densities were significantly higher in the control group (p = 0.020).Conclusion: The results obtained support concomitant molar extraction with BSSO as a feasible option.

The aim was to investigate oral health in randomly selected patients with chronic kidney disease (CKD). Data obtained by structured interview (self-reported lifestyle, oral symptoms and regularity of dental visits) and oral examination of patients with CKD from the Copenhagen University Hospital. Fourteen patients with CKD were screened. Only half of the patients reported regular dental visits and poor dental status was registered in half of the patients. Oral mucosal changes were registered in thirteen patients (93%). Eleven patients (79%) had gingival inflammatory disease. Twelve patients (86%) were carriers of Candida, and three (21%) had oral candidosis. Six patients (43%) had low whole saliva flow rate. Twelve patients (86%) reported at least one oral symptom. Overall, there was no differences in oral symptoms or findings related to kidney transplanted or not transplanted patients. The small sample size most likely influences the results. However, the vast majority of patients with CKD reported oral symptoms and only half consulted a dentist regularly. Poor dental status, oral mucosal changes and gingival disease were prevalent findings. Patients with CKD need focus on daily oral healthcare and regular dental visits. Interdisciplinary cooperation could encourage patients with CKD to focus on oral health.
