Abstract:
BACKGROUND: Studies have shown that conventional flap-guided bone tissue regeneration is a method commonly used in the immediate implantation of the upper anterior teeth. It is an ideal method for repairing small bone defects, but it is difficult to achieve favorable osteogenesis effect in the tooth neck area. OBJECTIVE: To evaluate the clinical effects of modified flap immediate implant in maxillary aesthetic area. METHODS: Sixty cases of immediate implant placement were investigated, and randomized into two groups: 30 received modified flap immediate implant in which a gingiva former with suitable size was screwed followed by buried healing (experiment group) and 30 received traditional flap immediate implant in which a cover screw was screwed followed by buried healing (control group). They were impressed digitally and restored with all-ceramic crown 6 months after the surgery. Implant retention rate, pink esthetic scores, gingival growth and labial bone absorption were detected and compared between two groups. RESULTS AND CONCLUSION: The implant retention rates of both groups were 100%. Compared with the control group, the pink esthetic score and gingival growth were significantly increased in the experimental group (P < 0.05), and the labial bone thickness was significantly decreased (P < 0.05). The proximal, distal or mesial gingiva growth was increased a bit in the experimental group compared with the control group, but there was no significant difference between the two groups (P > 0.05). To conclude, the modified flap immediate implant is conducive to soft tissue reconstruction in maxillary aesthetic area.
