About this trial
The current clinical implant techniques used include immediate implantation, early implantation, and delayed implantation. With the acceleration of the current pace of life, immediate implantation is increasingly favored by patients due to its advantages such as fewer surgeries, shorter waiting times, and less impact on aesthetics. The research group has shown that the mismatch between traditional implants and extraction sockets in immediate implantation surgery has caused some complications. Therefore, it is believed that 3D printed personalized root shaped implants with certain roughness are more suitable for use in immediate implantation surgery.

Treatment groups
Trial outcomes
Primary outcomes
Alveolar ridge height
The distance from the top of the alveolar ridge to the tip of the implant
Secondary outcomes
Width of alveolar ridge, buccal and lingual directions
The width of the implant platform from the buccal and lingual to the alveolar bone
Implant mobility
Measure the movement of the implant using an implant mobility meter and record the ISQ value
Gingival condition
Two independent clinical doctors conducted gingival examination in the oral implant area of the patient, and gave a comprehensive score for gingival condition based on changes in gingival color, shape, and texture. A 3-point scoring method was used, with good, average, and poor results.
Exploration depth and Exploring bleeding
Same periodontal probing. Use blunt head periodontal probing to measure the depth of probing at six points around the implant, including the buccal mesial, buccal central, buccal distal, lingual palatal mesial, lingual palatal central, and lingual palatal distal. Record the depth of probing and calculate the average value, 2-4mm if normal, if depth \>5mm, consider the occurrence of periimplantitis. The improved gingival sulcus bleeding index (mSBI) can be used to detect bleeding: 0=Along the periphery of the implant, no bleeding after soft tissue edge exploration; 1=scattered points after exploration, hemorrhage in shape; 2=After diagnosis, the bleeding appears linear in the groove; 3=severe or Spontaneous bleeding.
