Abstract :Purpose To examine the effectiveness and safety of immediate implant placement insert ignore into journalissuearticles values(IIP);, we evaluated the risk of lingual plate perforation insert ignore into journalissuearticles values(LPP); and mandibular canal perforation insert ignore into journalissuearticles values(MCP); associated with posterior mandible anatomy using cone beam computed tomography insert ignore into journalissuearticles values(CBCT); images. Materials and Methods A morphological study of the molar sockets of 135 patients insert ignore into journalissuearticles values(age: 18–84 y); was done and its relationship to the mandibular canal was investigated. The risk of LPP and MCP was recorded as yes or no. Mandibular cross-sectional morphology was defined as one of three types insert ignore into journalissuearticles values(U-P-C); using the criteria of Chan et al. Results The risk of LPP was significantly higher for second molars insert ignore into journalissuearticles values(p = 0.0001);, and the risk increased with age insert ignore into journalissuearticles values(p = 0.039);. There was a strong relationship between the risk of LPP and cross-section type U insert ignore into journalissuearticles values(p = 0.0001);. The mean root to alveolar canal insert ignore into journalissuearticles values(RAC); distance insert ignore into journalissuearticles values(mm); of males was significantly higher than that of females. The mean RAC value was 5.02 mm for males and 3.49 mm for females. There was no statistically significant relationship between the risk of MCP and sex. There was a significant relationship between the risk of MCP and cross-section type U insert ignore into journalissuearticles values(p = 0.0001);. Although the MCP risk was higher in second molars, there was no statistically meaningful relation between MCP and tooth type. Conclusion The results suggest that IIP in the mandibular molar area carries a high risk of MCP and LPP. Based on the elevated level of risk, a delayed implant protocol should be considered.
