Brief summary

Objectives: to investigate the success rates, marginal bone level, implant stability and patient satisfaction with immediately loaded single oral implants placed in fresh extraction sockets in anterior maxilla. A total of 32 participants will receive immediately loaded Co-Axis implants (Southern Implants, Irene, South Africa) placed into fresh extraction sockets. The control group is from a previous research project of similar design (Hall et al., 2007) which involved immediate loading of single oral implants placed in healed sites in anterior maxilla

Interventions

Immediate loading of single tapered oral implants placed immediately following extraction of maxillary anterior and premolar teeth.
