Objective To analyze the effect of minimally invasive dental implant technology in the treatment of mandibular molar tooth loss and its inffuence on aesthetics. Methods A total of 72 patients with mandibular molar tooth loss admitted to our hospital from April 2023 to April 2025 were selected, and they were divided into the reference group and the study group by the random number table method, with 36 patients in each group. The reference group was treated with traditional gingival ffap operation for dental implant, and the study group was treated with minimally invasive dental implant technology. The surgical indicators, occlusal function, aesthetics and periodontal indicators were compared between the two groups. Results The operation time, postoperative redness and swelling time, wound healing time and postoperative pain time in the study group were shorter than those in the reference group (P<0.05). At 3 months after treatment, the maximum occlusal force, maximum occlusal contact area, PES and WES scores in the study group were higher than those in the reference group, while the occlusal force asymmetry index, gingival index and bleeding index scores were lower than those in the reference group (P<0.05). Conclusion The application of minimally invasive dental implant technology in the treatment of mandibular molar tooth loss can effectively improve occlusal function and periodontal health, with high aesthetics, as well as shorter operation time and duration of postoperative symptoms.
